Viagra, Cialis, and Similar Drugs Double the Risk of Melanoma, Studies Find

Viagra, Cialis, and other erectile dysfunction (ED) drugs may raise more than just your libido, a number of studies suggest.

The results of several studies, conducted by different experts, in different locations, during different years, have suggested a positive link between the use of phosphodiesterase (PDE) inhibitors and the likelihood of developing melanoma. PDE inhibitors are mainly used to treat ED by increasing the flow of blood to the penis. However, the same chemicals which allow it to do this also prevent the body from blocking the growth of cells responsible for melanoma.

In 2014, the Journal of the American Medical Association (JAMA) Internal Medicine published the results of a long-term study with almost 26,000 male participants was conducted in the US by a team lead Qing Li, PhD, of the Harvard Medical School. These results suggested that the use of Viagra could increase the risk of developing melanoma by more than 80 percent, which is nearly double the risk associated with non-users.

In 2015, the results of a separate study were published. This time, researchers collected data from almost 24,000 male participants in Sweden. Despite the differences though, both studies came to the similar conclusions.

In 2016, the Cell Reports published one more study led by Robert Feil of the University of Tübingen, one of Germany’s oldest and most famous universities. The results of his team’s research suggest that a class of ED drugs called sildenafil, which includes Viagra, can actually encourage the growth of skin tumors, provided that they are consumed frequently enough and in high enough doses.

Following the publication of these studies, especially the one released in 2014, hundreds of individuals have filed lawsuits against pharmaceutical companies like Pfizer, the manufacturer of Viagra. Most of these claims mainly allege that the pharmaceutical companies have the duty to ensure the quality and safety of their products.  Additionally, they should provide the consumers with adequate warning as to the potential side effects of their products, so that they can make a more informed decision as to whether or not they should use the same.  Taken as a whole, these allegations suggest that the companies involved put their desire for profit above and beyond their responsibilities to the consumer.

If adequate warning was provided, many unfortunate victims may have avoided contracting melanoma by choosing not to take ED drugs, or they could have at least received early diagnosis and treatment for the disease because they were specifically looking for its symptoms.

Should you be an ED drug user who is experiencing symptoms of melanoma, consult a medical professional right away. If you’re still interested in filing a lawsuit against the manufacturer after you’ve received the requisite treatment, rest assured that the O’Brien Firm is ready, willing, and more than qualified to take your case.
