Viagra comes in pills of 50mg or 100mg each with 50mg being the recommended dose for most men.

Sildenafil Citrate (Generic Viagra) belongs to a group of medicines that delay the enzymes called phosphodiesterases from working too quickly. The penis is one of the areas where these enzymes work. Sildenafil Citrate is used to treat men who have erectile dysfunction (also called sexual impotence).
