Revatio warnings
It is necessary to conduct a medical examination for the diagnosis of erectile dysfunction before starting Revatio therapy. It is also necessary to discuss with your doctor the possible risk of cardiovascular complications due to sexual activity.
Revatio therapy may cause a reversible decrease in blood pressure. Before you start using Revatio, you should discuss the risk of adverse effects from low blood pressure (especially the risks associated with sexual activity). Patients with LVOT obstruction (including aortic stenosis) are most prone to the hypotensive effect of vasodilators.
Most side effects occur in people with previous diseases of the heart or blood vessels. These complications may arise either immediately after sexual intercourse or a short time after. Doses of more than 200 mg do not increase the efficacy of the drug. They will increase the frequency and severity of dose-related side effects.

Inhibitors of cytochrome CYP3A4 and CYP2C9 isoenzymes reduce the metabolism and increase the concentration of Revatio in the blood. Therefore, treatment should be started with a dose of 25 mg.
It is not recommended to mix Revatio and ritonavir.
Grapefruit juice can moderately increase the concentration of Revatio.
Nicorandil can potentiate the side effects of Revatio.

Combination therapy with alpha-blockers can lead to orthostatic hypotension, especially in the first 4 hours after taking Revatio.
