What's Sildenafil?

Sildenafil (aka, sildenafil citrate) is proven to combat erectile dysfunction and help you get hard when the time is right. Sildenafil citrate is a well known PDE5 inhibitor that has been prescribed by doctors for the last 20 years, ever since Viagra® was first approved in 1998.

How to take Sildenafil

Typically sildenafil is recommended to be taken on an empty stomach about an hour before you plan to get busy, and you should be able to keep that erection strong for as long as it’s needed.

Sildenafil side effects

Some men experience a tingly feeling in their body, headaches, temporary visual symptoms and other side effects from sildenafil.

If you are experiencing side effects that are bothersome or persistent, use our platform to talk to a clinician who can recommend adjustments to your treatment.

Viagra® vs Sildenafil

The main difference is branding and price. Viagra® is a brand name medication invented by Pfizer, while sildenafil (or sildenafil citrate) is the active ingredient in Viagra® that’s responsible for its positive effects on treating erectile dysfunction.
