Viagra

Viagra (Sildenafil) is a phosphodiesterase inhibitor manufactured by Pfizer and approved by FDA in 1988. It is a drug widely used to treat erectile dysfunctions in men and pulmonary hypertension. Pfizer has two patents for Sildenafil, one is indicated to treat cardiovascular disease and marketed as Revatio which has already expired in 2012 and another is indicated to treat erectile dysfunction and marketed as Viagra, the patent for Viagra will expire in 2019 in USA.

A study conducted in 2014 stated that, there is an 84% increased risk of melanoma (skin cancer) associated with Viagra while other studies also suggests that it may increase the risk of vision problems like blindness. It is been said that men who use Viagra tend to double the risk of developing Melanoma, the most dangerous form of skin cancer. Some studies have put out the estimates as people dying of Melanoma do have majority of male population.

Major complications of Viagra

Viagra Lawsuits

The U.S. Food and Drug Administration ordered a warning to be added to drug's label about vision loss in 2005 and in October 2007, and requested changes in the label to include warnings about sudden hearing loss associated with the drug, when they received 29 reports of patients who experienced sudden hearing loss within hours to two days of taking Viagra.

The manufacturer of Viagra, Pfizer, has failed to adequately warn the consumers about the dangers of NAION and about studies connecting the highly sold drug to increased melanoma risk and hence facing various defective drug lawsuits.

All federal Viagra lawsuits have been centralized into a Multi-District Litigation (MDL No. 2691) in the U.S. District Court for the Northern District of California under Judge Richard Seeborg in April 2016 by Federal judges which involves melanoma (skin cancer) cases.

Melanoma developed claims are still in the initial stages.
