Cautions when Taking

Before the start of drug therapy to diagnose erectile dysfunction and the reasons why it has occurred, it is necessary to collect history and conduct a physical examination. Before the treatment of erectile dysfunction is necessary to assess the risk of cardiovascular complications resulting from sexual activity.

Sildenafil causes mild reversible reduction in blood pressure. Before using the preparation, there should be eliminated the risk of adverse effects from blood pressure reduction, especially against sexual activity. Patients with obstruction of the left ventricle (including aortic stenosis, GOKMP) or with a rare syndrome of multiple atrophy of impaired regulation of blood pressure are most susceptible to the hypotensive effects of vasodilators. Most undesired effects from the CCC develops in people with previous heart disease or blood vessels. Most often, these complications occur either immediately after sexual intercourse, or shortly thereafter. In some cases, these effects occur after using the preparation without intercourse. A causal relationship between these effects and the described factors has not been established. Doses greater than 200 mg do not increase efficiency, but enhance the frequency and severity of dose-related side effects.
