2 These are prescription-only medicines (POM). Sildenafil belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. It works by helping to relax the blood vessels in your penis, allowing blood to flow into your penis when you get sexually excited. Sildenafil will only help you to get an erection if you are sexually stimulated. You should not take sildenafil if you do not have erectile dysfunction. You should not take sildenafil if you are a woman. Sildenafil is a treatment for men with erectile dysfunction, which is also sometimes known as impotence.

3 This is when a man cannot get, or keep a hard, erect penis suitable for sexual activity. Based on the data submitted by Macleods Pharma UK Limited, Sildenafil 25 mg, 50 mg and 100 mg film-coated tablets were considered to be generic versions of the innovator products, Viagra 25 mg, 50 mg and 100 mg film-coated tablets (Pfizer Limited). No new or unexpected safety concerns arose from these applications. It was judged that the benefits of Sildenafil 25 mg, 50 mg and 100 mg film-coated tablets outweigh the risks; hence Marketing Authorisations have been granted.
