Sildenafil is the generic version of Viagra®—same active ingredient, same results, just without the brand name price. It’s a more affordable way to effectively treat erectile dysfunction.

Sildenafil is a take-it-when-you-need-it treatment for ED, meaning daily use isn’t required. To get the most out of it, it’s usually best to take a dose on an empty stomach about an hour before sexual activity. Always follow your healthcare provider’s guidance for the best outcome.

Possible risks of this medication include flushing, headache, nausea, dizziness, chest or arm pain, and in rare cases, changes in vision or loss of sight. If you experience an erection that lasts more than four hours or becomes painful, seek emergency medical attention immediately.

Avoid drinking excessive amounts of alcohol, such as five or more drinks, while taking sildenafil
