Sildenafil Treatments

Sildenafil is an active ingredient used in certain medicines for erectile dysfunction (ED). It belongs to a class of medicines called phosphodiesterase type 5 (PDE5) inhibitors and works by supporting increased blood flow to the penis during sexual stimulation.

Sildenafil-containing medicines are available in different strengths and formulations. Their suitability depends on individual health circumstances, other medications and the regulatory status of the particular product.

In the UK, authorised sildenafil medicines are available through regulated healthcare providers and pharmacies. Some sildenafil-containing products marketed internationally, including Kamagra, do not have UK marketing authorisation.

This section provides information about sildenafil-containing formulations, their differences, potential side effects and important medicine-safety considerations.
