What Is Sildenafil?

Sildenafil is an oral prescription medication. The prescribed product label identifies its strength and instructions. High-fat meals can affect absorption; ask the prescriber about administration and food.

Who May Be a Candidate

A clinician reviews symptoms, cardiovascular history, blood pressure, kidney and liver conditions, and all medications before prescribing. An intake does not guarantee a prescription. In-person assessment or referral may be required. Do not take PDE5 inhibitors with nitrates or riociguat. Combining PDE5 inhibitors can cause dangerous blood-pressure drops; do not combine medications on your own. Alpha blockers and other blood-pressure medicines require interaction review. Tell the clinician about cardiovascular disease and whether you have been advised to avoid sexual activity.
