Melanoma Risks Caused by Viagra and Cialis?

According to allegations raised in a recent complaint filed against Pfizer and Eli Lilly, side effects of Viagra and Cialis used for treatment of erectile dysfunction caused an Alabama male to be diagnosed with melanoma.

Melanoma is an aggressive and potentially life-threatening form of skin cancer.

William Kelly in the U.S. District Court filed for the Northern District of California in November, claiming drug makers failed to warn users and the medical community about the melanoma diagnosis risks.

These risks may now be associated with the blockbuster drugs Viagra and Cialis.

Mr. Kelly indicates that he was prescribed Viagra for treatment of erectile dysfunction in 2000, and later switched to Cialis, which he continued to use until 2012. However, in 2011, a biopsy of a skin lesion on his left leg led to a malignant melanoma diagnosis.

This required Mohs surgery in December 2011 and again in April of 2012. As a result of the diagnosis, Kelly suggested that he must remain vigilant for a return of the skin cancer for the rest of his life.

“While designing and formulating Viagra and Cialis, Defendants discovered or should have discovered that the drugs’ mechanism of action, the inhibition of PDE5, also presented a significant risk of exacerbating melanoma,” states the lawsuit.

“Despite these significant findings, Defendants have made no efforts in their ubiquitous Viagra and Cialis advertisements to warn users about the potential risk of developing melanoma that has been scientifically linked to these drugs.”

The case collaborates a growing number of Viagra lawsuits currently pending against Pfizer. There are several other Cialis lawsuits being investigated against Eli Lilly.

These pending suits allege that if users had been provided warnings about the risk of melanoma, they may have been cautiously monitoring for changes in the skin.

Others argue they may have elected not to use the prescription drugs for treatment of erectile dysfunction in the first place. Melanoma treatments in Maryland are successfully done at Dr. George Verghese’s innovative SRT Cancer Treatment practice.
