Which dose of viagra is best?

This section covers common questions about the dosage of Viagra.

You may have heard Viagra described as the “little blue pill.” Viagra comes as a tablet that you swallow. It’s a blue tablet that has a rounded diamond shape.

Viagra is available in three strengths: 25 milligrams (mg), 50 mg, and 100 mg.
