Sildenafil is medicine, taken in the form of a tablet, which can be used to treat symptoms of erectile dysfunction (ED) in men over the age of 18.

Sildenafil contains the same active ingredient as Viagra, so they work in the same way. The main difference is that Sildenafil has a different name and packaging, and is usually much cheaper.

Sildenafil works by helping to relax the blood vessels in your penis. This allows blood to flow into your penis when you get sexually aroused. Sildenafil will only help you to get an erection if you are sexually stimulated.

How to use

Please read the patient information leaflet before use.

  • Take Sildenafil about an hour before you want to have sex.
  • Swallow the tablet whole with water.
  • 100mg is the maximum dose of Sildenafil. Do not take more than one tablet a day.

Sildenafil stays active in your body for around four hours after you take it.
