Viagra: a detailed guide to a drug that improves potency

In the fight against poor potency, doctors often use various medications, the most famous of which in Russia is Viagra. The product enhances erection during sexual arousal and is suitable for men of all ages.

We will provide excerpts from the official instructions for the use of Viagra and tell you what effect it has on the male body. We will share data on the dosage regimen and the possible consequences of use.

What is the composition of the drug?

Modern means of self-defense are an impressive list of items that differ in their operating principles. The most popular are those that do not require a license or permission to purchase and use. In the online store Tesakov.com, you can buy self-defense products without a license.

The main active ingredient of the drug is Sildanefil. Sildanefil is a synthetic substance that was originally developed to normalize the functioning of the cardiovascular system. The effective effect on potency was discovered by chance as a result of clinical trials. In addition to the main active component, the structure of the drug contains: magnesium stearate, calcium hydrogen phosphate and other substances. They do not have pharmaceutical effectiveness and are intended to give the medication a tablet-like, solid texture (used as fillers).

Overdose

The daily dose of sildenafil should not exceed 100 milligrams. If a patient accidentally takes too much dosage, they should seek immediate medical attention regardless of the presence of severe reactions.

Interaction with other chemicals

The components that make up Viagra are not compatible with all chemicals, and therefore can cause changes in the effect of other medications. Before starting treatment with sildenafil, you should inform your doctor about all medications taken to treat other diseases or chronic pathologies.

It is strictly forbidden to take Viagra simultaneously with medications containing nitrates. This cannot be done even if the treatment is carried out from time to time and is not permanent.

The chemical processes that are triggered in the body when PDE5 inhibitors and nitrates come into contact disrupt the functioning of the cardiovascular system. This threatens a sharp decrease in blood pressure, which can lead to death. Less “harmless” consequences of this combination include dizziness, loss of consciousness, myocardial infarction, and stroke.

Most often, nitrates are contained in medications intended to treat heart pathologies, as well as “soft” drugs sold in nightclubs. If a man is not sure whether his medicine contains nitrates, he should check its compatibility with Viagra with his doctor.

Deterioration of health may occur with simultaneous treatment with sildenafil and alpha-blockers, which are the basis of drugs intended for the treatment of arterial hypertension and inflammatory processes in the prostate.

Incompatibility is manifested by a drop in blood pressure, general weakness, and dizziness. In this case, treatment should begin with a minimum dose of 25 mg of the active component.

HIV-positive patients taking antiretroviral therapy should also be careful when taking PDE 5 inhibitors. For such patients, individual dosage selection is required; you should start with the minimum.

Do not take Viagra together with other pharmaceutical products that increase potency or are intended for the treatment of erectile dysfunction. Moreover, the form of these products does not matter; tablets, injections, vacuum pumps, implants, etc. are prohibited.

Interaction with alcohol

Ethanol, which is included in any alcoholic drink, has an extremely negative effect on the functioning of all internal organs, and primarily on blood flow.

This fermentation product slows down the movement of biological fluid, as a result of which the genitals become less full, which affects the strength of the erection. In such a situation, the use of reverse-acting drugs (which includes Viagra) is simply useless.

There are also cases where the simultaneous use of sildenafil and alcohol led to a general deterioration in health, impaired coordination of movement, tachycardia, and chest pain. For these reasons, taking Viagra and alcoholic beverages is not recommended.

In what form is Viagra available?

Viagra is available in packages containing from 1 to 12 tablets

Viagra comes in the form of diamond-shaped tablets, convex on both sides. The concentration of the main active ingredient varies from format to format and is 25, 50 and 100 mg per tablet. The dosage is selected based on the severity of erectile dysfunction and the nature of the potency disorder. You cannot choose the dose yourself; this is a direct path to health problems. Packages contain from 1 to 12 tablets. Cost varies according to quantity.

Viagra: how to use it correctly

Detailed instructions are included in each package. And although Viagra is not a drug, doctors still advise you to carefully read it before taking pills. The dosage is commercially available in three variations:

The dosage is prescribed by the doctor. Based on the instructions, it is worth remembering the following rules of use:

• Drink 30-60 minutes before intimacy;
• Do not mix with alcoholic beverages;
• Do not eat fatty foods before taking it, but it is better to drink it on an empty stomach;
• Try not to exceed the dose of 100 mg per day.

It happens that the first dose does not give the desired effect. In this case, you can take the pill again, slightly increasing the dose. It often happens in men that the drug begins to take effect only on the third or even fourth try. The time of onset of action of the tablets is also completely individual. But on average, the expected effect occurs within thirty minutes and lasts for two to four hours. Long-term use of Viagra is not addictive.

We must not forget that not only before exceeding the dose of the drug, but also simply before taking Viagra, a medical consultation is necessary. It simply will not help a completely healthy man without physical disabilities.

Viagra - pills for men: their action, reviews, price - all this, and not only, can be read here. The packaging should be kept away from children, in a dry place where the temperature does not exceed 30 C. The drug can be stored for up to five years. One package of Viagra (1 tablet) will cost approximately 900 rubles.

How does the drug work and when is it obviously ineffective?

The drug is aimed at improving blood supply to the penis (corpus cavernosum). By normalizing blood circulation in the genital area, Viagra provokes a rapid onset of erection and retention of persistent potency for from several tens of minutes to an hour or even more. However, Viagra is far from a panacea.

It is not suitable in a number of cases:

• Low libido. First of all, the drug is ineffective for decreased sexual desire. Libido is an indispensable attribute of normal potency. If there is no sexual desire, Viagra will be ineffective. Watching pornographic materials is not enough, make no mistake. As a rule, most often we are talking about a physiological decrease in libido as a result of testosterone deficiency, taking certain categories of drugs (neuroleptics, antidepressants, etc.).
• Lack of sex hormones. Another important factor is the presence of normal hormonal levels. If the level of androgens, particularly testosterone, is insufficient, Viagra will be an ineffective drug. The blood supply to the penis will be optimal, but an erection will not occur.
• Normal blood circulation in the genitals. The drug is ineffective for use in people who do not have problems with blood supply to the penis. If it is tried simply for the sake of an interesting experience, it will not produce any additional effect. Everything else is legends and speculation.
• Vascular pathologies of the penis. If there are diseases of the vessels of the penis, Viagra will not be of any use. The pharmaceutical product in question is not a medicine in itself. It only increases blood flow. But if the vessels have lost their elasticity and are not able to expand, for obvious reasons there will be no effect.
• Atherosclerosis of the vessels of the penis. Another factor in the ineffectiveness of the drug. Moreover, if there is occlusion of the lumen of veins and arteries by cholesterol plaques. The problem is most often observed in obese patients, smokers, people who abuse alcohol and fatty, fried, salty foods.
• Other disorders of the patency of blood supply structures.
• Prostatitis. Prostatitis entails a violation of innervation, therefore Viagra, which only affects blood circulation, is not effective.
• Psychogenic erectile dysfunction. If the patient has psychogenic erectile dysfunction, Viagra will not help. This is a completely different problem; it is not of a purely physiological nature. We're talking about psychosomatics.

Thus, Viagra can help only with minor circulatory disorders in the pelvic area. For the effect to occur, you need to have, paradoxically, a healthy body.

Reviews from men

Customer reviews are always an indicator of the effectiveness of a drug. According to the data stated in the instructions for use, Viagra has a beneficial effect on the reproductive system after initial use. Below we have collected reviews from men about Viagra tablets for one-time use (names have been changed for ethical reasons; age limits are indicated correctly):

I didn’t have any problems with erections, but I really wanted to try Viagra just for fun, because the name has long become a household name. I took a Viagra 50 mg tablet. while walking along the embankment with my girlfriend - I wanted to return to my room (in an hour or two) and immediately get down to business. The action began about an hour later, and for about thirty minutes I hid the “hip part” from passers-by. The result is the following: I didn’t want any preludes, I was ready to get down to business right away. The partner quickly got tired from such sexual contact and did not receive pleasure, and I could not fall asleep for a long time. Conclusion: the drug works well, but before using it, be sure to consult a doctor, he will decide which dosage is right for you - 25 mg (for those who do not have problems with potency), 50 mg. or 100.

My youth is gone. My wife and I have long forgotten about sleepless nights. And then she suddenly suggested trying Viagra. Frankly speaking, I am against chemistry and pills, because... I am sure that apart from a bad effect on the body, they bring nothing. I resisted for a long time until my wife brought the pill herself. The price at the pharmacy is 500-600 rubles for one such pill. But what an effect! Three weeks later, the erection problems went away. We sit with my wife and write praises for Viagra - she is on women’s forums, I am on men’s forums, because... Both were satisfied! In a week or two I plan to consolidate the result with dietary supplements or medicinal herbs.

I am a middle aged man. I won’t brag about my achievements in bed. I have dealt with Viagra more than once - sometimes for the sake of interest, sometimes with the aim of solving a “pressing problem”. Based on reviews from men and my own feelings, I can say the following about dosages: 25 mg. suitable as a “warm-up”, 50 mg is used by people with real problems with potency, but keep in mind that after 4 months the effect will weaken and the dosage will become insufficient. Another interesting fact is that abuse of Viagra by people over 40 will lead to a feeling of “hangover” after using it, and if your dosage is 100-150 mg. (unacceptable without consulting a doctor.), rapid heartbeat and complete lack of concentration will become your companions. Viagra is a worthy remedy, I won’t say anything, but don’t abuse it. Consult your physician before use. When they take 8 painkillers for a headache (after all, the headache will go away faster), an ambulance arrives half an hour later. It's the same story here. Take the pills in the minimum dosage - the quieter you go, the further you will go.

Mechanism of action

After taking the medication, it is quickly absorbed into the bloodstream. The mechanism of erectile function is associated with an increase in the concentration of nitric oxide in the cavernous body of the penis. This substance stimulates the production of guanylate cyclase, a special enzyme. The presented substance is intermediate; it itself stimulates the activation of the substance cGMP.

Increased potency after taking Viagra occurs only with high-quality sexual arousal

The muscles of the penis relax, its tone decreases, and increased blood circulation is observed in the genital area. As the manufacturer himself points out, in order for the drug to begin to act normally, it is required that the man experience high-quality sexual arousal. Otherwise, the action will not occur. The maximum concentration of the drug in the bloodstream is achieved after half an hour to two hours.

The drug is metabolized in the liver structures, the period of elimination of safe metabolites is approximately 3-5 hours from the moment of administration. Most of the metabolites are excreted in feces (about 85%), the rest is transported by the kidneys. Drug processing products are inactive.

Comments on reviews

Most of the comments from men who have purchased Viagra are positive. Today there are many truly working pills for men, but they act specifically. Some representatives of the stronger sex noted that they bought pills on the Internet - the price of Viagra there is lower. But men experienced strange side effects from the pills ordered online (noise in the head, stuffy nose), but the night went well.

As users say, although the price at the pharmacy is higher, it is safer to buy there. Although, it is often more difficult to buy Viagra at a pharmacy due to male complexes.

Buy this drug from trusted pharmacy chains.

In what cases is the use of the drug permissible and recommended?

According to the instructions for use, the medicine is used for the complex treatment of erectile problems that are of a vascular nature. In all other cases, the drug has no effect. To normalize sexual function, it is necessary, firstly, to stimulate the genital organ, and secondly, to use other drugs. As part of monotherapy, the drug is rarely used.

Viagra is effective in a healthy body

Consequences of overdose

Any drugs and medicines that are sold in pharmacies must be taken strictly according to the instructions (the use and effect of Viagra must be prescribed there). There are cases where men took too many pills for fun. For example, 36-year-old Daniel Metford took 35 tablets at once and soon felt severe dizziness and hallucinations. Everything around him “painted” green. In this case, the situation occurred in a state of strong stimulation of the penis. The erection lasted 5 days. The penis “jumped” from any touch.

How does Viagra work for men?

In this case, the patient was helped. But there are also cases where, in the event of an overdose, the genital organ had to be amputated due to inflammation. There were situations with cardiac arrest.

Therefore, tablets should not be abused.

In what cases should Viagra not be used?

Viagra is a rather heavy drug. It must be used with great caution. Absolute contraindications include:

• liver dysfunction in the decompensation phase;
• immune response (allergic reaction to the components of the drug);
• problems with the optic nerves;
• severe diseases of the cardiovascular system (stage 3 hypertension, coronary heart disease and other cardiac diseases);
• Also, you should not take the drug simultaneously with nitrogen compounds (nitrates “from the heart”, sports drugs “for pumping” - donors of nitric oxide).

Taking precautions, the medication can be used for:

• diseases of the digestive tract (including gastritis, stomach and duodenal ulcers);
• arterial hypertension of mild and moderate severity;
• in case of Peyronie's disease and other anatomical defects of the penis;
• increased blood fluidity;
• previous infarction of the heart muscle or cerebral structures;

Treatment regimen for erectile dysfunction

For most men, Viagra is recommended at a dosage of 50 mg, but if this amount is not enough and the body tolerates the effects of sildenafil well, the dosage can be increased to 100 mg. If you feel worse, the dose is reduced to 25 mg.

Dosage depending on the situation:

• for severe renal failure - 25 mg;
• for liver diseases, including hepatosis and cirrhosis - 25 mg;
• in combination with ritonavir - 25 mg every two days;
• in combination with erythromycin, the initial dosage is 25 mg once a day, further depending on the circumstances;
• When taking adrenergic blockers, administration is possible only after stabilization of hemodynamics.

The maximum allowed number of tablets is one per day. You need to drink it an hour before the intended sexual intercourse. Viagra cannot be combined with alcoholic beverages.

For older men, the dosage is the same as for young men.

Side effects

Side effects are varied:

• secondary prostatitis and dysfunction of the prostate gland;
• pain in the muscles;
• conjunctivitis (inflammation of the membranes of the eyeball);
• weakness;
• flu-like symptoms;
• temporary color blindness (usually goes away within a few hours);
• lymphadenitis;
• secondary pharyngitis;
• diarrhea;
• dyspeptic symptoms;
• secondary rhinitis;
• skin rash.

A number of side effects limit the use of Viagra

In addition to the phenomena described, the following conditions are somewhat more common:

• fainting, increased blood pressure, heart rhythm and breathing disturbances;
• priapism (long, painful erection not associated with sexual arousal);
• immune response (allergy).

FAQ: Answers to frequently asked questions

• How often should you take Viagra?

If you do not experience any side effects, it is acceptable to use the drug on a daily basis (but not more than once a day!). And although Viagra is not a hormonal drug, consultation with a specialist is recommended.

• Can a healthy man use drugs that improve erection?

Yes, this option is acceptable, but pay attention to the dosage of the drug, because an excess of sildenafil in the body can cause the so-called “hangover” feeling and some side effects.

• How long does Viagra last for the male body?

You should not feel overwhelmed or overtired. The drug begins to act after 40-60 minutes and a visible effect is observed over the next 4 hours with a gradual fading of the erection.

• What dosage to use for the first time?

An experienced doctor will tell you how many milligrams of Viagra to take to achieve the effect. It is better to start with a lower dosage.

• What to do when taking Viagra is accompanied by side effects?

In this case, the doctor will most likely recommend several options for you:

1. reduce the dosage to the minimum acceptable;
2. abandon the drug, replacing it with natural supplements.

How to take the drug correctly?

The optimal starting dose is 50 mg per day. It is best to use the medicine approximately an hour and a half before sexual intercourse. The product is used strictly before meals so that nothing interferes with the absorption of the active substance.

You cannot independently determine the dosage and nature of your intake. The regimen of use should be determined by the treating specialist, andrologist or sexologist, after thorough diagnosis and consultation.

Long-term use of Viagra leads to a decrease in the effectiveness of the drug and the opposite effect. It is optimal to take the drug with a minimum dose, gradually increasing it until a lasting therapeutic effect occurs.

Pharmacokinetics

The method of absorption of tablets is linear. Bioavailability can be up to 63%, and the maximum concentration in the blood increases after an hour. This effect is observed when taking the drug on an empty stomach, which cannot be achieved when taken simultaneously with food. The worst way to absorb the medicine is with fatty foods - the effect occurs only after 2 hours.

The main metabolite quickly binds to plasma protein. Regardless of the dose, 96% of the product is absorbed within an hour, and after 90 minutes its components are detected in semen.

Metabolization occurs mainly in the liver, and the cytochrome isoenzyme has a significant influence on it. The concentrations of metabolites in the blood are about 40% of the dosage of the active substance of the tablet. Their traces remain in it for another 4 hours.

Viagra analogues, comparison of drugs

The main analogues of Viagra are Cialis and Levitra. They are the ones most often prescribed for erection problems. All three drugs have an identical effect, inducing increased blood circulation in the pelvic area. However, there are marked differences between the drugs. They are presented in the table:

Thus, the question of the effectiveness of a particular drug is controversial. It all depends on the degree of impairment, the patient’s health status and what the person himself requires. In any case, you cannot do without a doctor’s recommendation.

Contraindications to the use of Viagra

Experts say that Viagra has a fairly wide list of contraindications that should not be forgotten before use. “Love Pills” should not be used in the following cases:

• A person is taking medications to treat pulmonary hypertension. There are also a number of prohibited drugs that are strictly prohibited from being used together with Viagra. For this reason, you should discuss this possibility with your doctor before use.
• Blood pressure disorders.
• The person has recently had a stroke or heart attack.
• There are problems with the kidneys and liver.
• Difficulties with the circulatory system.
• For stomach ulcers.
• If a man has retinitis pigmentosa. This is an eye disease that can be inherited.
• The man's penis is severely deformed.

Viagra is not a safe drug at all, and therefore can only be taken by those people who have good general health, but at the same time have problems with potency.

Anonymous reviews from men

Review #1:

“I am a young man and previously had no problems with intimacy until my girlfriend said that she would like everything to last a little longer. Like, she doesn’t have time to get any pleasure from what’s happening. These words puzzled me, but I decided to listen to her words and try to find a solution to the problem. I didn’t feel like going to the doctor, but soon I saw an advertisement for Viagra tablets on TV. There is hardly a man who has never heard of this miracle drug. And I decided to try.

The price for one tablet is almost 1000 rubles, but what can you do? I took it as instructed and soon got down to business. After just one treatment, the girl was satisfied, and so was I - after all, this time everything really lasted much longer. But immediately after, my blood pressure rose sharply and I had a severe headache.

Later, in addition to the headaches, vision deterioration (thank God, only temporary), drowsiness and lethargy were added. It was hard to fall asleep at night, and then I had to fight sleep all day. It became scary to drive.

And one day my girlfriend noticed that my whole face was red. And, as it turned out, not for the first time. I had to tell her everything. She asked me to stop taking these pills. I stopped and turned to a specialist who was able to solve my problem without expensive medications and unpleasant consequences.”

Review #2:

“Hello, I would like to share with everyone on this forum my successful experience of taking Viagra.

Now I'm almost thirty. I first tried it when I was younger. Just out of curiosity. Now I periodically use it to sometimes add some zest to my intimate life. I am a completely healthy man, I have no complaints about anything. But I really like the effect of these pills. And the girls are delighted with me. I can do it up to five times a night. And if without Viagra, then much less, and the process is shorter. The orgasm after taking it is simply something. You can’t really describe it in words, you just have to experience it yourself.

As for side effects, there have never been any. Neither after the very first dose, nor in the future. Over the several years that I have been taking the drug. If you act strictly according to the instructions, then everything is great.”

4 BEST WAYS TO ENLARGE YOUR PENIS!

1. The most effective and proven is Mighty Tool. They write a lot about it, reviews can be read here.
2. You can use different exercises to enlarge your penis.
3. Using magnification devices such as an extender.
4. And, of course, the surgical route is a dangerous operation, but it works 100%.

Review #3:

“Viagra is a relative drug. It may suit some people, it may not suit others. Just like any other pill. I myself am physically healthy, my penis is large, I don’t complain about the quality of sex. There is just a desire sometimes to prolong the pleasure a little for both yourself and your partner.

You can often find similar discussions on forums. These are ordinary tablets. Blue, diamond shaped. The package contained four pieces of 25 mg each. I drank one half an hour before bed, but instead of the expected excitement, a wild headache began. The skull seemed to be bursting at the seams for about three hours. And no painkillers helped. There is no time for closeness anymore. But when I did, the sex turned out to be very ordinary. The same as it was before taking the drug. Either I chose the wrong dosage, or Viagra is simply not for me. And the price is not cheap!

I decided not to throw it away and next time I drank all three remaining ones at once. I finally felt the action in full. I had a lot of fun, but then my head hurt again. To summarize, I can say that the pills are effective, but the consequences are not the most pleasant.”

Review #4:

“There is hardly a drug more famous in the segment of potency stimulants than Viagra. It has been on the market for several years now, but it hasn’t gotten worse during this time. If you strictly follow the attached instructions, then there will be no particular harm to the organs; the blood flow will be strong, even if the dose itself is small. At least a couple of hours of pleasure are guaranteed. True, I personally have a slight headache in the morning. Yes, the drug is not cheap. And this is its main disadvantage. But it has long proven its guaranteed impact.”

Viagra: a powerful potency stimulant with few side effects

Viagra is a non-hormonal means of strengthening potency. The active component of the drug is sildenafil citrate. The compound is a selective inhibitor of phosphodiesterase type 5 (PDE5). During sexual arousal, the substance relieves spasm of the capillaries of the cavernous bodies of the penis, thereby eliminating obstacles to the free filling of the organ with blood. Sildenafil is non-toxic and has a minimal number of side effects. Viagra acts locally in the genitals, practically without affecting the functioning of other body systems. The medication is well tolerated by the vast majority of men aged 18 to 69 years, but in some cases it can cause negative reactions.

Consequences after taking the drug

For some men, taking Viagra causes various side effects. Usually such symptoms are temporary. But as the dose increases or the drug is abused, the side effects become stronger and stronger. Most often, patients experience:

• nasal congestion;
• temporary visual impairment;
• noise in ears;
• headache;
• cardiopalmus;
• redness of the facial skin.

Such phenomena can occur with a single dose of the medicine. They usually disappear as sildenafil is eliminated from the body.

In rare cases, more severe and long-lasting side effects occur:

• insomnia;
• nausea and vomiting;
• severe tachycardia;
• rhinitis;
• allergic reactions with rash and itching;
• flu-like condition;
• cystitis;
• hearing impairment;
• sinusitis;
• prostate dysfunction;
• disturbance of color perception.

In such cases, Viagra withdrawal and medical consultation are required. Under no circumstances should you increase the dosage of the drug yourself. It is very easy not to calculate the required amount and get an overdose, which is difficult to treat. It is important to know that sildenafil is absorbed very quickly and binds well to blood proteins. It is not so easy to remove it from the body during intoxication.

Regular use of Viagra is not recommended for young men

Young men who do not have problems with potency should not take Viagra. It must be remembered that this is a medication that should be used according to indications. Otherwise, you can train your body to react only to artificial stimulants, after which a natural erection will be difficult to achieve.

Compound

What are the contraindications and side effects of Viagra? What do men and women think about the drug?

Before looking for answers to these questions, it is necessary to study not only the pharmacology of the drug, but also its composition. This is an extremely important point. It is possible that someone will immediately refuse to use it after studying detailed information about the medication.

The Viagra tablet contains:

• microcrystalline cellulose;
• magnesium stearate;
• titanium dioxide;
• croscarmellose sodium;
• lactose;
• calcium hydrogen phosphate.

The active substance in this drug is sildenafil. Thanks to it, blood vessels dilate and blood circulation in the body improves.

Who should not take Viagra

Viagra tablets (sildenafil)

• Persons taking organic nitrates and nitrites, since sildenafil enhances their hypotensive effect and can reduce blood pressure to a critical level.
• Men for whom sexual activity is undesirable or contraindicated for health reasons, for example, in the presence of severe heart failure.
• People who have lost vision in one eye as a result of non-arterial ischemic optic neuropathy.
• Adolescents who have not reached puberty and persons under 18 years of age.
• For women, so as not to cause hormonal imbalance, as there are other drugs for them.

In addition to its main indication, sildenafil is able to influence the vessels of the respiratory system and reduce the pressure in them. Taking Viagra also lowers blood pressure and reduces shortness of breath. True, these indicators return to their previous places after the end of the action of the tablets.

For decades now, the legendary drug has held a leading position among erection enhancers. After all, a full sex life is one of the main criteria for success for many men. And thanks to Viagra, the former energy and joy of life returns.

What is the duration of action?

The absorption time of sildenafil into the blood depends on the contents of the stomach at the time of administration. If the tablet is taken on an empty stomach, its active ingredient enters the blood within 30-40 minutes. When taking the drug after a meal, especially if it contained a lot of fat, penetration of sildenafil into the bloodstream should be expected after 1.5 hours. On average, 1 hour is enough to ensure the desired effect.

The instructions indicate the duration of action after taking the tablet - 4-5 hours. But in each specific case this period will be different. Much will depend on the individual characteristics of the male body.

After taking Viagra, judging by the reviews of men, the duration of action of the tablets can range from 2 hours and up to the whole night.

Contraindications

What are the contraindications of Viagra for men and women? Ideally healthy people do not have to worry about this. They are allowed to take the study drug without any particular concerns.

Contraindications include:

• pregnancy;
• breastfeeding period;
• childhood;
• period of taking nitrate-containing medications;
• taking the drug together with generics.

This is a list of main contraindications. Women's Viagra has exactly the same side effects and recommendations for use as men's. Therefore, next we will consider female and male pathogens together.

Composition and release form

Viagra is presented for sale in the form of diamond-shaped, biconvex tablets with rounded, cut edges. On one side there is an engraving of Pfizer, on the other there is information about the concentration of sildenafil. The tablets are covered with a blue film coating, placed one or two pieces in blisters, which are packed in a cardboard box of 1-2 units; four pieces each - 1 or 3 blisters in a pack; 12 pieces each - 1 blister in a pack. The composition of one tablet is presented in the table:

Viagra and alcohol

According to the instructions, Viagra for men is undesirable in combination with alcohol and tinctures. From a chemical point of view, the substances do not interact, but ethanol reduces the rate of absorption of sildenafil and increases the load on the heart muscle and the body. It is safe to combine 50 mg of the drug with the following amount of alcohol: no more than 100 g of vodka, 700 ml of beer or 450 ml of wine.

Compatibility of Viagra with alcohol, food and medicines

Acceptable combinations with the drug

1. Viagra does not interact with aspirin; their simultaneous use is acceptable.
2. Viagra and alcohol are compatible. But alcohol can have a negative effect on erection and the risk of side effects increases when using the drug and alcohol simultaneously.
3. Fatty foods inhibit the absorption of sildenafil into the blood, resulting in the effect of the drug occurring an hour later.

Dangerous combinations

1. Medicines containing nitrate are prescribed for the treatment of angina pectoris (nitroglycerin, cardilate, nitrograde, etc.). The danger of this combination is that blood pressure may drop sharply and a heart attack may occur.
2. Blue tablets should not be taken together with cimetedine, erythromycin, ketoconazole, or beta blockers.

By adhering to the listed rules for using the drug, you can significantly reduce and even eliminate the occurrence of side effects from Viagra. And although this remedy cannot cause pathologies in men after long-term use, you should not abuse it.

Viagra tablets action

Under the influence of the drug, sex lasts three to five times longer than usual

Sildenafil does not have a direct relaxing effect on the muscle tissue of the penis. It enhances the effect of nitric oxide, which, in turn, increases the tone and elasticity of the smooth muscles of the penis. Under the influence of Sildenafil, the blood is filled with oxygen and blood circulation is activated.

In this case, a stable erection appears immediately after sexual arousal. Sildenafil inhibits the action of the PDE-5 enzyme. The substance blocks nerve impulses sent to the brain to constrict blood vessels, preventing premature ejaculation. Under the influence of Sildenafil, sex lasts three to five times longer than usual, and an erection lasts for four to five hours.

The medicinal component increases the sensitivity of the nerve endings of the erogenous zones, enhances orgasm, and increases endurance. Regular use of the drug allows you to completely get rid of premature ejaculation and improve the quality of your erection. The effect of Sildenafil is reduced by consuming fatty foods. Foods containing more than 30% fat slow down the absorption of Sildenafil from the walls of the stomach, as a result of which the substance is poorly absorbed and does not have the expected effect.

Features of taking Viagra

Combination with medications

The combination of drug therapy and drug intake must be agreed upon with your doctor. To reduce the risks and side effects associated with taking Viagra, you must remember that many medications cannot be used simultaneously with this drug. But, for example, Viagra and Aspirin can be used simultaneously; these drugs do not interact with each other.

Medicines prescribed for the treatment of heart disease and containing nitrate cannot be used together. A one-time dose threatens to sharply reduce blood pressure and provoke a heart attack.

Among the medications incompatible with Viagra are the following:

1. Nitroglycerine;

Combination with alcohol

When combining a potency drug and alcohol, you need to keep in mind that alcoholic drinks are not conducive to impotence, have a negative effect on erection, and increase the risk of side effects.

Food

Knowing how the drug works, you need to choose a diet. When taking the drug to enhance potency, you must avoid foods that are too fatty and difficult to digest. Such products inhibit the absorption of sildenafil and weaken the effectiveness of the drug. Therefore, for potency, choose natural, easily digestible foods.

Taking Viagra and conceiving a child

To understand whether Viagra is harmful for couples seeking fertilization, you need to know how the main component of the drug, sildenafil, works. It is designed to enhance potency, enhances blood flow and does not in any way affect the quantity and quality of seminal fluid. Common myths about negative consequences, the inability to get pregnant and subsequently have healthy children, are associated with ignorance of the principle of action of the drug and a reluctance to acquire such knowledge.

This means that the side effects of Viagra do not affect the possible conception of a child and do not affect further pregnancy and the health of the unborn baby. Viagra tablets increase the chances of becoming parents, people who have tried taking them convince. Strong children born to couples who use stimulants clearly answer the question of whether their use affects the health of future generations.

Studies conducted by medical centers confirm that the active component sildenafil does not affect the ability to conceive. It has the ability to influence the process of sexual intercourse without affecting the composition and quality of sperm.

To confirm this, studies were conducted on the seminal fluid of male volunteers before and after taking the drug. The identical composition of the semen confirmed the spectrum of action of the drug, which means the man who took it should not have any fears or doubts. This confirms that the harm of Viagra, supposedly extending to subsequent generations, is nothing more than fiction.

Action of the drug and composition

As part of Viagra, Sildenafil has a stimulating effect on erection. Please note that this drug only works in the presence of natural sexual arousal. It relaxes the muscles of the penis, causes active blood circulation inside the pelvic organs, increases the sensitivity of erogenous zones, and enhances orgasm.

Sildenafil is an inhibitor of PDE5, an enzyme that causes premature ejaculation. Thanks to the active action of Sildenafil, the work of the enzyme slows down, resulting in intimate contact lasting much longer.

Viagra has a tonic effect on the body as a whole: it increases vitality and stamina, gives vigor and self-confidence.

The drug prevents the development of inflammation and diseases of the pelvic organs, restores their healthy microflora, increases testosterone levels and normalizes hormonal levels. Viagra not only stimulates the production of seminal fluid, but also improves its quality.

A little history

At the end of the last century, the world-famous company Pfizer was developing a drug that was supposed to reduce the intensity of pain during angina pectoris. During the first clinical trials, it was discovered that the active substance of the drug, sildenafil, has a specific effect, increasing blood circulation in the pelvic organs and increasing potency.

The unexpected side effect pleasantly surprised the men who volunteered for the trial. And enterprising managers figured out how to make a profit from an accidental discovery. So, in record time, a new drug called Viagra appeared in pharmacies, the creators of which were awarded the Nobel Prize.

Analogs

We have considered the contraindications of Viagra for men and women in full. And the possible side effects of the drug too. Now it remains to find out what medications can be used instead of the one proposed.

There are a lot of analogues of Viagra. Among them, various generics are most often found. But doctors often prescribe the following remedies:

• "Arsenal";
• "Potenzagra";
• "Potential";
• "Viasil";
• "Kamangra".

You will have to check with your doctor for more accurate information. Or ask the pharmacist at the pharmacy. Finding the pathogen is not difficult. But actually curing impotence is a task beyond the capabilities of Viagra. A person may require complex therapy with medication and a strict diet.

I guess that's all. We managed to study the most complete information about Viagra. Now each person can decide whether he needs to take this drug. You can’t expect long-term healing from impotence from him. This is simply impossible.

Instructions for use

The most pressing question on the Internet is how to take Viagra for men for the first time? In fact, the question is reasonable, since only a medical specialist can choose the most effective and harmless dosage for the body. For the rest, all the subtleties of using Viagra, indications and contraindications, the summary will tell you everything.

Indications

The remedy for low potency or erectile disorders speaks for itself in terms of indications and reasons for its use. Taking synthetic stimulants without a doctor's prescription is extremely risky, since irrational use of potent stimulants can have the opposite effect.

Doctors refer to any erectile disorders as indications, for example, weak and flaccid, unstable and short-lived erections, premature ejaculation, decreased potency and libido. Sildenafil will be effective if sexual dysfunctions and disorders are caused by nervous disorders or poor circulation. If the problems are caused by other pathologies, they must be treated initially, since the stimulant will not be effective.

Directions for use and doses

The instructions for use may not always be a reliable source of information; usually the annotation for the drug offers generally accepted standards; more precise recommendations are given by the doctor. You can use the tablet only once a day; with a single use, it is important to maintain the optimal dosage.

To begin with, Viagra should be taken in a dose of 25 mg to experience the degree of its effectiveness. For older men, it is prohibited to exceed the daily dose of 50 mg of sildenafil. The tablet is taken 30-60 minutes before sexual intercourse orally before eating. After this, the effect of the product will last about 3-4 hours.

Important! Exceeding the dosage of 100 mg of Viagra per day is contraindicated, since the drug can disrupt the functioning of other systems and organs, causing severe side effects.

Contraindications

Since we are talking about a synthetic drug, there are strict contraindications for it. Namely:

• intolerance to components in the composition;
• parallel intake of nitrates and nitrites, nitric oxide donors;
• doctor’s contraindications for male sexual activity;
• optic neuropathy, causing loss of vision in one eye;
• liver dysfunction;
• women and men under 18 years of age.

The drug is used with caution in cases of deformation of the penis, heart failure, hypotension or arterial hypertension, arrhythmia, internal bleeding, priapism, and unstable angina. Then the patient needs permission and special instructions with dosages from the treating doctor.

Side effects

If a man ignores the contraindications and rules for using Viagra, the drug may cause side effects. Namely:

• allergic reactions;
• conjunctivitis;
• diarrhea, nausea;
• nasal congestion;
• flu-like syndrome;
• asthenia;
• inflammation of the pharyngeal mucosa;
• inflammation of lymphoid tissue;
• impaired color perception by the eyes;
• shortness of breath;
• sinusitis;
• increased muscle tone;
• development of infections within the body;
• impaired prostate function;
• headaches and dizziness.

Often, due to an overdose of such a stimulant, a man experiences redness of the face, accelerated breathing and heart rate. This suggests that the dosage taken caused excessive stimulation of the body, which, after the effect was canceled, would be replaced by a loss of strength. Therefore, it is extremely important to start taking pills correctly with minimal doses.

Appearance to the world

It's hard to believe, but Viagra is an accident. The original patent and the right to the brand, drug and sales belong to the American pharmaceutical company Pfizer. As befits any drug company, Pfizer engaged in private research. One of the pressing problems of that time (although the situation is no better now) was heart failure, and all the geniuses of pharmacy fought hard against it, constantly searching for a remedy that could improve or partially restore blood flow to the main muscle of the body - the heart, without any special consequences and overload of the body.

Our regular reader got rid of problems with potency using an effective method. He tested it on himself - the result was 100% - complete relief from problems. This is a natural herbal remedy. We tested the method and decided to recommend it to you. The result is fast. EFFECTIVE METHOD.

It was the early nineties, in America there was a flourishing of medicine and the sphere of convenience of human life. The competition between private pharmaceutical companies was impressive, but they all worked separately, without giving away their secrets. And then one day, in 1992, Pfizer began work on a new drug (sildenafil citrate), which in the future was supposed to become a unique remedy for heart problems. The drug passed initial tests and the creators gained access to the opportunity to try it on people. The results were not impressive - the blood flow to the heart was far from what we would like, and the patients did not note any significant improvements in their condition, as well as complaints about the drug. The original goal of making the myocardium work harder and also changing blood pressure was failed.

However, the experimental department noticed one surprising pattern. Many male patients, after completing therapy, openly or covertly refused to return the remaining medication back to the laboratory. It took some time to understand the root cause of this strange behavior - after all, not a single woman from among the subjects was noticed in this way, and the scientists responsible for the experiment began to figure out what could be the matter and how the drug could surprise men.

By the way, it is not surprising that Viagra had no effect on women. The female genital organs work completely differently, and the flow of blood to the pelvic organs will not have any effect other than the expected - redness and a feeling of warmth. Simply put, Viagra has no effect on women or worsens their well-being, in rare cases disrupting the pressure in the body.

Everything was resolved in a rather unexpected way. It turned out that although sildenafil did not have the desired effect on the heart, it can indeed cause significant blood flow to the organs that work on this principle. And the penis, as we know, is one of them, since it consists entirely of a “spongy” type of tissue and is activated only by blood. When excited, the brain sends a signal and blood flows to the organ - this is exactly what we call an erection. Thus, many men noticed this strange side effect on themselves, quite logically associated the sharp improvement in the quality of their potency with the drug and refused to return the pills - in those days there were no analogues of Viagra, with the exception of folk remedies and the rarest aphrodisiacs.

Fortunately, the company’s management quite reasonably assessed the potential of this “side effect” of the drug Viagra and immediately ordered to begin new tests, but now of an innovative and at that time the most powerful means for improving and restoring male potency. The experiments began the following year and had a stunning effect that exceeded even the wildest expectations. The drug was named Viagra - from a combination of the English words “vigor” (energy, power) and Niagara (the name of the largest and most majestic waterfall in North America). Viagra has come a long way, but in 1998 it was officially certified and went on sale as “the most effective drug for impotence.”

In the same year, the creators of the product (three main researchers - Robert Furchgott, Luis Ignarro and Ferid Murad) received the highest award of the scientific world - the Nobel Prize in Medicine - for their innovative discovery. Photos of that momentous day can still be found online.

How Viagra acts on the body

If blood flows poorly into the penis, it probably leaves it too quickly and this is what leads to erectile dysfunction, and subsequently to impotence. The effect of Viagra occurs due to the dilation of blood vessels in the penis during sexual arousal. Thus, even after one-time use, blood circulation in the penis increases and an erection occurs.

There is an opinion that the tablets can begin to act without any stimulation. This is mostly discussed on forums. But it's not like that. An erection occurs independently, in the presence of stimulating factors. And the drug only helps to maintain it.
