Sildenafil
The active ingredient in Viagra® — an FDA-approved, on-demand ED treatment.
Sildenafil is a PDE5 inhibitor that improves blood flow to support erections. It’s the active ingredient in Viagra®, taken on-demand about an hour before activity.
Prescription required. Final clinical decisions rest with the prescribing physician.
What is Sildenafil?
Sildenafil increases blood flow to the penis by relaxing blood vessels, helping achieve and maintain an erection with sexual stimulation. As a generic, it offers the same active ingredient as Viagra® at a fraction of the brand price.
It’s taken on-demand, typically 30–60 minutes before activity, and lasts several hours. A physician confirms it’s appropriate — especially around heart health and any nitrate medications.
