PATIENT INFORMATION

STENDRA®

(avanafil) Tablets

Read this Patient Information before you start taking STENDRA and each time you get a refill. There may be new information. This information does not take the place of talking with your healthcare provider about your medical condition or your treatment.

What is the most important information I should know about STENDRA?

STENDRA can cause your blood pressure to drop suddenly to an unsafe level if it is taken with certain other medicines. Do not take STENDRA if you take any medicines called “nitrates.” Nitrates are used to treat chest pain (angina). A sudden drop in blood pressure can cause you to feel dizzy, faint, or have a heart attack or stroke.

Tell all your healthcare providers that you take STENDRA. If you need emergency medical care for a heart problem, it will be important for your healthcare provider to know when you last took STENDRA.

Stop sexual activity and get medical help right away if you get symptoms such as chest pain, dizziness, or nausea during sex. Sexual activity can put an extra strain on your heart, especially if your heart is already weak from a heart attack or heart disease.

What is STENDRA?

STENDRA is a prescription medicine used to treat erectile dysfunction (ED).

STENDRA is not for use in women or children.
