Propecia Sexual Side Effects Lawsuit

In Colorado, a Propecia sexual side effects lawsuit has been filed against Merck & Co., based on the allegation that the plaintiff suffered erectile dysfunction and other permanent sexual problems after taking the popular hair loss drug.

On October 14, “John Doe” filed the Propecia lawsuit in the U.S. District Court for the District of Colorado.  The plaintiff’s name has been withheld due to the intimate nature of his injuries.

In the complaint, the plaintiff alleges that he experienced the following Propecia side effects:

  • Erectile dysfunction
  • Decreased libido
  • Loss of sexual sensation
  • Decreased semen output
  • Testicular pain
  • Depression
  • Anxiety

This Propecia lawsuit is the latest in a number of Propecia lawsuits filed against Merck by men who claim that they suffer permanent sexual issues after taking the drug.  Though Merck has posted warnings of potentially permanent sexual side effects from Propecia in other countries, this risk has been downplayed in the U.S.  Plaintiffs also allege that Merck continues to provide misleading information that suggests that Propecia sexual side effects will abate when the medication is stopped, which is not always the case.

U.S. Propecia warnings indicate that a small number of men who experienced Propecia sexual side effects in clinical trials had the dysfunction resolve after they stopped taking the medication.  Nevertheless, recent research and numerous post-market reports involving men like “John Doe” suggest that these statements are false and misleading.

Merck updated the Propecia warning label as early as 2008 in several European countries, indicating that some men may experience persistent erectile dysfunction from taking Propecia.  Users and doctors in the U.S. have yet to receive that warning.  Propecia lawyers cite a number of doctors who claim they have repeatedly told Merck that Propecia sexual problems can be permanent, but have been rebuffed by the drug manufacturer.

In his lawsuit, “John Doe” charges Merck with negligence, failure to warn, designing and manufacturing a defective product, misrepresentation, breach of warranty and other charges.  He is seeking compensatory damages for pain and suffering, mental anguish, emotional suffering, medical expenses, and disfigurement.  The suit also asks that Merck be forced to pay back all revenue obtained through the manufacture, marketing, and sales of Propecia.

Propecia (finasteride) is a low-dose version of Proscar, a prostate hyperplasia drug, and has been approved to treat male pattern baldness.

A study published in March in the Journal of Sexual Medicine linked Propecia side effects to sexual problems in men.  Researchers indicated that drugs belonging to the 5-alpha-reductase inhibitor class can cause sexual issues and the growth of male breast tissue, and that in some cases these side effects appear to be permanent.
