Before taking this medicine
You should not take avanafil if you are allergic to it, or:
if you take medicine to treat pulmonary arterial hypertension, such as riociguat (Adempas).
Do not take avanafil if you are also using a nitrate drug for chest pain or heart problems. This includes nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate. Nitrates are also found in some recreational drugs such as amyl nitrate or nitrite ("poppers"). Taking avanafil with a nitrate medicine can cause a sudden and serious decrease in blood pressure.
Tell your doctor if you have ever had:
heart failure;
angina (chest pain);
a heart rhy disorder;
a heart attack or stroke;
heart surgery;
severe or uncontrolled high blood pressure;
low blood pressure;

bleeding problems;
a blood cell disorder such as sickle cell anemia, multiple myeloma, or leukemia;
a stomach ulcer;

priapism (an erection that is painful or lasts longer than 4 hours);
a physical deformity of the penis (such as Peyronie's disease); or

How should I take avanafil?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.
Avanafil can be taken with or without food.
Avanafil is usually taken only when needed, about 15 to 30 minutes before sexual activity. Follow your doctor's instructions.
Avanafil can help achieve an erection when sexual stimulation occurs. An erection will not occur just by taking a pill.
Do not take avanafil more than once a day. Allow 24 hours to pass between doses.
