How should this medicine be used?

The terms are pretty much interchangeable, the way you might say “Kleenex®” to refer to a tissue. The only real difference between the two medications for ED is how much they cost. Viagra® is a well-known and widely used medication for treating erectile dysfunction (ED), one of the most common sexual dysfunctions in the world. Formulated as that iconic little blue pill, Viagra has the longest history of any FDA-approved ED treatment on the market today. Both generic sildenafil and Viagra work by increasing blood flow to your penis, making it easier for you to get and maintain an erection.

When is the best time to take Viagra?

Sildenafil belongs to a class of enzyme-inhibiting drugs called phosphodiesterase type 5 inhibitors, or PDE5 inhibitors. Like the others in its class, sildenafil works by relaxing the muscle tissue inside the walls of your blood vessels, allowing the vessels to dilate, and improving blood flow throughout some parts of your body — including your penis. It's important to note that these erectile dysfunction medications aren't wonder drugs. They only work if you're sexually stimulated. But if you’ve got sexual stimulation and these pills, research shows that you have an effective, reliable erectile dysfunction treatment. Your healthcare provider will tell you the specific dosage of brand-name Viagra or generic sildenafil that you should use if you’re prescribed this medication.
