STENDRA (avanafil) is a prescription medication used to treat ED (erectile dysfunction, the inability to attain or maintain a penile erection). You will not get an erection just by taking this medicine. STENDRA helps a man with ED get and keep an erection only when he is sexually stimulated and works in approximately 30 minutes. It works by increasing blood flow to the penis so that you can get and maintain an erection long enough for sexual activity. Take STENDRA 100 mg or 200 mg as early as 15 minutes before sexual activity. Take STENDRA 50 mg approximately 30 minutes before sexual activity. Do not take more than one STENDRA per day and doses should be taken at least 24 hours apart. This product is not for use in women or children.
