On December 11, 2015 a legal document captioned In re: VIAGRA® PRODUCTS LIABILITY
LITIGATION, MDL No. 2691 was filed with the Judicial Panel on Multidistrict Litigation (JPMDL)
seeking consolidation of all Viagra – melanoma lawsuits pending in various federal courts around
the country. Soon thereafter, on December 22, the Defendant in those lawsuits, Pfizer, filed a
response to the Plaintiffs’ motion to transfer, agreeing that all these Viagra drug injury lawsuits
should be consolidated in an MDL which should be assigned to the Northern District of California,
a specific division of the federal court system.
The next JPMDL hearing is scheduled for March 31, 2016, and we expect to have the Viagra
MDL ruling issued some time in April 2016, as things stand now.
Viagra (sildenafil), the most common drug prescribed for male erectile dysfunction (ED), appears
to increase the risk for invasive melanoma but not cutaneous squamous cell carcinomas nor
basal cell carcinomas.
Essentially, Viagra acts by inhibiting phosphodiesterase 5 (PDE5). Experimental in vitro studies
show that PDE5 inhibition augments tumor cell invasiveness, supporting this new Viagra side
effect finding
There are four other ED drugs which are phosphodiesterase 5 (PDE5) inhibitors:
 Cialis (tadalafil)
 Levitra (vardenafil)
 Staxyn (vardenafil)
 Stendra (avanafil)
In addition, Cialis is prescribed sometimes when doctors see the signs and symptoms of benign
prostatic hyperplasia (BPH) — as some of you may know from the Cialis TV advertisements.
Two other phosphodiesterase 5 (PDE5) inhibitors are Revatio (sildenafil) and Adcirca (tadalafil).
These drugs are prescribed for the treatment of pulmonary arterial hypertension (PAH).
Medical researchers involved with this still emerging drug-safety issue seem to believe that these
six other drugs (in addition to Viagra) are probably associated with an increased risk of melanoma
skin cancer, too.
We are currently investigating cases of melanoma in men who used Viagra, Cialis, Levitra,
Staxyn, or Stendra, as well as men and women who used Revatio or Adcirca. These cases are
possible drug injury lawsuits against the responsible pharmaceutical companies, not the
prescribing doctors.
