The FDA is going to study a potential link between melanoma skin cancer and erectile dysfunction (ED) drugs such as Viagra, Cialis, and Levitra, according to information set forth in this document “January – March 2016: Potential Signals of Serious Risks/New Safety Information Identified from the FDA Adverse Event Reporting System (FAERS)”.
In relevant part, the document listed these drugs which have been associated with melanoma as a serious side effect.
PDE-5 inhibitors:
Adcirca (tadalafil; Eli Lilly and Company): tablets
Cialis (tadalafil; Eli Lilly and Company): tablets
Levitra (vardenafil hydrochloride; GlaxoSmithKline): orally disintegrating tablets
Revatio (sildenafil citrate; Pfizer): tablets, oral suspension, and injection
Staxyn (vardenafil hydrochloride; GlaxoSmithKline): orally disintegrating tablets
Stendra (avanafil; Vivus and Auxilium Pharmaceuticals): tablets
Viagra (sildenafil citrate; Pfizer): tablets
On the legal front, a growing number of Viagra – melanoma lawsuits have been filed against the drug company Pfizer. The federal court cases were consolidated in April 2016 before U.S. District Judge Richard Seeborg in the Northern District of California. Those Viagra cases are now part of a multidistrict litigation which often goes the short name “Viagra federal court MDL 2691”.
As regards the general nature of these Viagra – melanoma lawsuits, many of the filed Complaints include allegations along these lines:
- Pfizer knew Viagra posed a cancer risk and purposely concealed facts regarding the drug’s safety;
- Pfizer failed to sufficiently investigate the link between Viagra and an increased risk of melanoma prior to
FDA approval; and, - Pfizer failed to warn users about the link between Viagra and the increased risk of melanoma even after studies showed the
association, and instead continued promotion of the product.
