Even though many people do not know that sildenafil is yet the another name of Viagra, many more will probably not know that besides the primary use of this medicine, or besides treating the problems of erectile dysfunction, this medicine is also used for the treatment of the problems of pulmonary arterial hypertension. It functions in the way that it relaxes the arterial wall, thus reducing the pressure and the resistance in the pulmonary arteries. This is also the reason why some professional sportsmen use it, believing that it can enrich their muscles and thus improve their performance. Since recently, sildenafil is used in the treatment of the altitude sickness, as well as for the prevention of this condition, because it has proved to be helpful.
Speaking of the side effects of this drug, everyone, or at least the great majority of the male population, is probably familiar with the serious and damaging effect that this drug may have on the heart. But, the truth to be told, the fact is that the most common side effects of sildenafil are not at all serious, because they are related to headache, dyspepsia, diarrhea, unexplained rash, or nasal congestion and some problems with vision. Infections of the urinary tract are also possible, as well as infections of the respiratory system and back pain. Those which are more serious, but at the same time less frequent, are angina pectoris, cataracts, temporary loss of vision or hearing, depression, insomnia, and congestive heart failure. However, it is important to know that these side effects have been reported in less than 2 % of the people who used this medicine.
Rare, but yet possible are heart attack, arrhythmias, stroke, hypertension, bleeding in the lungs or within the brain, or sudden death. However, these are all extraordinarily rare cases, and the majority of the people who experienced these side effects had some of the risk factors. Also, according to the statistics and reports, all of these side effects usually happen either during or after the sexual activity, which stresses out that this medicine is not intended for everybody, and that it is important to consult the healthcare provider before using this drug, and inform him thoroughly about the medical history. In some cases, it is possible for the person who uses it to experience allergic reaction as well, but unfortunately, this is not something which can be predicted in advance.
