According to an article published online April 7, 2014 in JAMA Internal Medicine, the use of sildenafil (Viagra, Pfizer) is associated with an increased risk of developing invasive malignant melanoma. Other medications used to treat erectile dysfunction, including Cialis and Levitra, were not studied as they were not approved at the time that this study was initiated.
Although further studies are needed, one with a history or malignant melanoma or a family history of melanoma should seriously consider avoiding the use of PDG5A inhibitors (Viagra, Cialis, or Levitra). It is recommended that one discuss this with their Primary Care Physician or Dermatologist.
