Career, recognition in society, physical strength - the main components of male self-confidence. But the first place is taken by potency. When in an intimate life a man does not have problems, then everything else is easily obtained. If the problem exists, many try to solve it with the help of sildenafil, the active substance of Viagra. But the side effects of Viagra in this case, few people know.
Male potency is based on three components:
- desire or attraction (psychological component);
- erections (physiological component);
- achievement of ejaculation.
Potency will be ideal only if all three elements work together. Difficulties for men can occur at any age, at any stage. The psychological component is the main and the most difficult: if a man does not feel attracted to a woman, then this fact will be difficult enough to change. But the physiological side of the potency can easily change with the help of Viagra.
The history of Viagra began in 1992, when the English pharmacological firm Pfizer was working on testing a new drug Sildenafil citrate. An interesting fact is that the company initially did not plan to create tablets to increase potency. Sildenafil citrate was to be an effective treatment for heart and vascular diseases. At the stage of drug testing, it was found that Viagra does not affect the mechanisms of the cardiovascular system - its effect manifested itself in a completely different place. Subjects refused to return Viagra, as it miraculously increased the erection in men. Clinical studies have confirmed the effectiveness of sildenafil for various erectile dysfunction.
In 1998, Viagra appeared on the market in the form of blue tablets and quickly received positive reviews. In a short time, she gained popularity and took the leading position among drugs that improve erection in men. This magic remedy is widely used by fully healthy people, as well as suffering from diabetes and other ailments. But, like any medicine, Viagra has its own contraindications, side effects.
Contraindications to the use of the drug
Viagra tablets, in addition to high efficiency, also differ in good tolerability. But a number of diseases, in the presence of which you should very carefully approach the reception of this drug, still exists. All contraindications are mainly reduced to cardiovascular diseases. The full list of caveats looks like this:
- Heart failure.
- Angina pectoris.
- Cardiac ischemia.
- A heart attack.
- Disorders of cerebral circulation.
- Uncontrolled hypotension.
- Thrombosis of the arteries.
- Myeloma disease.
- Cell anemia.
- Anatomic deformation of the penis.
No contraindication should be left without attention, as a negligent attitude to the presence of any from the above list can have serious health consequences, and in some cases even lead to of death.
In studies of the negative consequences of Viagra, data from one year were studied. There were 522 deaths in 1473 cases of negative consequences. Of these, the cause of death in 200 people was myocardial infarction, and 94 people stopped their heart during intercourse.
All accidents occurred within the first six hours after taking Viagra. This fact indicates that the drug was in the blood of a person at the time of his death. But the manufacturer of Viagra has never lost in the trial, since all the victims suffered from a particular heart disease. The cause of death in all cases are heart attacks, and it is difficult enough to prove in court what they are caused by: physical activity during sexual intercourse or drug action.
Studies have shown that cases of heart attacks and cardiac arrest during coitus with the use of Viagra do not exceed the expected for elderly men, the frequency of heart attacks during the same process, but without the use of drugs that increase potency. To protect yourself from possible unwanted, life-threatening consequences, you should carefully consider contraindications.
Possible side effects
In the first years of the drug's existence, 29 facts of deafness, complaints of ringing in the ears, dizziness after taking Viagra were registered in the market of medicines. Careful studies of these facts have not found a direct relationship between drug use and the occurrence of a side effect.
A little later, doctors began to suspect that sildenafil adversely affects the sense of smell. On this occasion, scientists from Dresden carried out serious research, the results of which were published by the popular medical journal Journal of Urology in 2007. The publication provided evidence of the effect of the drug on the circulation of blood in the nose.Despite the revealed shortcomings of the drug, the side effects are minor, temporary and not may cause significant harm to health (except for people suffering from the above diseases).
In general, side effects occur when violations of tolerable doses, along with other drugs. The recommended daily dose is 50 mg of the substance. Depending on the tolerability and taking into account the individual characteristics of the human body, this dose can be reduced to 25 mg or increased to 100 mg. If you do not violate the frequency of application (1 time per day) and the maximum dose (100 mg), then undesirable sensations are much less common. Without consulting a doctor, you should not experiment with doses of sildenafil.
The most common side effects are: dizziness, headache, redness of the skin, nasal congestion. There may also be indigestion, a slight change in vision (impaired clarity, increased photosensitivity). To prevent unwanted "special effects" from taking this remedy, do not forget about compatibility and incompatibility of the drug with other substances that enter the body: alcohol, medicines and food.
Compatibility of Viagra with alcohol, food and medicines
Admissible combinations with the drug
- Viagra does not interact with aspirin, their simultaneous use is permissible.
- Viagra and alcohol are compatible. But alcohol can adversely affect the erections and the risk of side effects with the simultaneous use of the drug and alcohol is increased.
- Oily food slows the process of sildenafil absorption into the blood, as a result of which the action of the drug comes an hour later.

- Medical preparations containing nitrate are prescribed for the treatment of angina pectoris (nitroglycerin, cardilate, nitrograss, etc.). The danger of this combination is that blood pressure can drop dramatically and a heart attack may occur.
- Do not take blue tablets with cimetidine, erythromycin, ketoconazole, beta-blockers.
