When was Viagra go off patent to the World?

Even though Viagra won't officially go off patent until 2020, Pfizer's 2013 settlement with generic manufacturer Teva Pharmaceuticals allowed for Teva to introduce a generic version of Viagra—for which Pfizer will receive royalties—beginning in December

The length of time Viagra will last for will depend on individual factors. For example, some men claim the effects have lasted for up to 5 hours. However, on average the effects of Viagra tend to begin to wear off between 2 and 3 hours after taking the medication.

In general, Viagra takes about 30 minutes to produce noticeable effects. But your diet, your overall health, the medications you're taking, underlying conditions, and much more can all affect the amount of time Viagra takes to work in your body and how long it lasts.

With the expiration of Viagra three years away, you would think that the market for generics would be on hold until then. However, an Israeli manufacturer named Teva Pharmaceutical Industries Ltd. will be allowed to sell a generic version of Viagra beginning December 11, 2017.

Both Viagra and sildenafil are widely used to treat erectile dysfunction. In fact, they contain the same active ingredient. Viagra is a brand name for the sildenafil produced and sold by the company Pfizer. Sildenafil is also sold as a generic drug, which is medically identical to Viagra.

Sildenafil is used to treat male sexual function problems (impotence or erectile dysfunction-ED). In combination with sexual stimulation, sildenafil works by increasing blood flow to the penis to help a man get and keep an erection.
