What is the difference between Viagra and Sildenafil?

Sildenafil is the active medical ingredient found in Viagra. Up until June 2013, the pharmacetuical company Pfizer held the patent to produce the branded medication Viagra. Once this patent expired, many other pharmaceutical manufacturers started to produce UK licensed generic versions of Sildenafil at a lower price. An example of a few companies that manufacturers UK licensed Sildenafil include Teva, Sandoz, Mylan, Dr Reddys and Actavis. Generic versions of Sildenafil are proven to be clinically equivalent to Viagra but are available at cheaper prices as they are unbranded.

Can I use Viagra and Premature Ejaculation Treatment at the same time?

Viagra should be used with caution when taking premature ejaculation medication such as Priligy at the same time. This is as combination of these two medications can cause a drop in your blood pressure causing you to feel faint when standing up. To avoid suffering from a drop in blood pressure, we recommed that you leave a gap of at least 24-48 hours between taking ED medications such as Viagra (Sildenafil), Cialis (Tadalafil), Levitra (Vardenafil) and Spedra (Avanafil) and Priligy.
