Viagra and It's Side Effects

viagrapillViagra, along with Cialis and other ED medications, belongs to a class of drugs known as PDE-5 inhibitors. These drugs increase blood flow to the spongy tissues of the penis, which creates an erection.

Since Viagra was approved by the FDA in 1998, millions of men have taken the erectile dysfunction drug, making billions of dollars for Pfizer. (The price of one pill averages $25 and in 2012 alone it brought the drug company $2 billion in sales). Pfizer has aggressively promoted its blockbuster drug in direct to consumer advertisements in print and television as a safe treatment for ED. However, soon after it entered the market a number of serious side effects, including heart attacks and strokes, vision and hearing problems, were linked to Viagra. Viagra lawsuits followed.

Viagra NAION

The FDA in 2005 ordered that a vision loss warning be added to the Viagra label. Although PubMed (April 2006) "did not suggest an increased incidence of NAION in men who took sildenafil [Viagra] for ED", several studies indicate otherwise.

Studies have linked the use of Viagra with NAION (Wikipedia cites seven papers dating from February 2000 through August 2005, including two studies published in the Journal of Neuro-ophthalmology 25 (1): 9–13, and another in the Journal of Ocular Pharmacology and Therapeutics 21 (4): 315–7) See more about Viagra blindness and hearing loss.

Interestingly, Pfizer has recently applied for patents for "Innovations related to the treatment of anterior ischemic optic neuropathy", which is the condition its ED drug is allegedly linked to.

Viagra Melanoma

skincancercasepage A study published in The JAMA Internal Medicine(June 2014) showed that men who used Viagra were 84 percent more likely to develop melanoma over a period of ten years. The study comprised more than 25,000 men in the US averaging the age of 65, six percent of whom had taken Viagra to treat erectile dysfunction.

Researchers behind the JAMA report believe that Viagra affects the same pathways that allow cancers to spread aggressively. The ED drug lowers levels of a protein called PDE5A, which protects against cancer. This allows melanoma skin cancer cells to become more invasive.

The researchers identified 580 incidents of squamous cell carcinoma, 3,030 of basal cell carcinoma and 142 incidences of melanoma. While they found that men who used Viagra were at nearly twice the risk for developing melanoma, they didn't find a link between Viagra and risk for other types of skin cancers. Further, the researchers did not find any evidence that erectile dysfunction itself increased the risk of melanoma.

The study determined that those men who had ever used Viagra had double the risk of developing melanoma than those who never took the drug. Even men with no family history of the skin cancer or men who generally are not exposed to the sun are likely to have a greater risk of melanoma after Viagra use.

Melanoma is a deadly skin disease that kills about 9,000 people in the US alone annually, according to The American Cancer Society. The incidence of melanoma has steadily increased since the 1980s.

Viagra Lawsuits

A Viagra Melanoma lawsuit was filed in December, 2014 by an Illinois man. Edward Corboy Jr was prescribed Viagra in 2008 and was diagnosed with melanoma four years later. Corby says in his lawsuit that he never would have taken Viagra if he had known of its serious side effects. Corby claims he didn't know about the risk of skin cancer until the JAMA study was published in June of 2014.

Other melanoma lawsuits have similar allegations. Melanoma Viagra victims claim that, if information and warnings had been provided to them and their doctors, they may have avoided a diagnosis of melanoma by not taking the drug. Or if warnings were provided, a diagnosis of melanoma may have been detected in earlier stages.
