The Propecia lawyers at Saiontz & Kirk, P.A. were previously reviewing potential lawsuits for men throughout the United States who have experienced erectile dysfunction, impotence and other sexual problems from Propecia or Proscar. These side effects may persist even after no longer using the medication.

Financial compensation may be available through a Propecia lawsuit as a result of the manufacturer’s failure to adequately warn about the risk of permanent injury that may be suffered after taking the prescription medication to prevent or reverse male hair loss.

Propecia (finasteride) is a prescription medication introduced by Merck in December 1997 for treatment of male pattern baldness or hair loss. It is a low-dose version of the prostate drug Proscar, which also contains finasteride as the active pharmaceutical ingredient.

Side effects of Propecia have been linked to a risk of irreversible sexual problems that may persist even after the popular hair loss medication is stopped, such as:

  • Erectile Dysfunction (ED)
  • Loss of Libido or Sexual Desire
  • Impotence or Low Sperm Count
  • Male Breast Growth
  • Testicular Pain
  • Depression

Although it appears that Merck knew or should have known about this risk of Propecia problems, they failed to adequately warn consumers or the medical community, placing their desire for profits before the safety of men using the medication.

Male pattern hair loss is a naturally occurring phenomenon, which is neither an illness nor a disease. Although it may result in an appearance that some consider undesirable, it is important that a pharmaceutical company adequately and completely warn about any injury risk that could be associated with use of a prescription medication to treat this healthy and normal occurrence. Through Propecia litigation, former users are able to obtain compensation for damages and ensure that drug makers are held accountable for placing profits before consumer safety.

Since introducing Propecia for hair loss, Merck has engaged in an aggressive direct-to-consumer marketing campaign for their medication, which has been referred to as a “cosmeceutical” product. Within two years of receiving approval to sell Propecia, Merck was spending over $125 million a year advertising the product without adequate warnings about the potential Propecia sexual side effects.


Merck failed to warn about the potential risk of sexual problems from Propecia, denying and downplaying reports of serious adverse events that were received in association with the use of Propecia by men with male pattern baldness.

Propecia warnings provided in the United States suggested that sexual side effects were only seen in a very small number of men and indicated that the Propecia problems went away in men who stopped taking the drug. However, these statements were deceptive and misleading, as Merck failed to disclose the large number of users who were continuing to suffer persistent and irreversible Propecia sexual problems even after they stopped using the medication.

Recent research has indicated that erectile dysfunction and other sexual injury from Propecia often continues long after discontinuing the medication. Some doctors have indicated that the medication destroyed the life of patients, causing problems that substantially outweigh any concerns about the appearance of hair loss, often leading to depression, fatigue and other injuries.


The lawyers at Saiontz & Kirk, P.A. are reviewing potential Propecia class action lawsuits and individual Propecia injury claims for men who have been diagnosed with sexual problems, such as impotence, infertility, erectile dysfunction, loss of libido or other sexual side effects of Propecia.

All claims are pursued by our Propecia law firm under a contingency fee agreement, which means that there are no fees unless our attorneys are successful obtaining compensation for a sexual injury from Propecia.
