Propecia Warning Label Over Sexual Problems Updated

After substantial pressure and a mounting number of Propecia lawsuits filed by men who have experienced long-term sexual dysfunction, Merck & Co. has finally agreed to update the warning label for their popular hair-loss drug. The warnings were also updated for their higher-dose version of the medication, which is marketed as Proscar for treatment of enlarged prostate symptoms.

The lawyers at Saiontz & Kirk, P.A. are pursuing potential claims for men throughout the United States who have experienced long-term sexual problems from Propecia, which may include:

  • Erectile Dysfunction
  • Loss of Libido or Sexual Desire
  • Impotence
  • Infertility or Low Sperm Count

Although Propecia warnings have indicated that there is a potential risk of erectile dysfunction, misleading information was provided that suggested the problems resolve once the medication is no longer used. However, Merck has known for years that men throughout the United States have been experiencing persistent sexual dysfunction from Propecia long after the medication is stopped.

While the warning label was updated in several other countries as early as 2008 to provide information about reports of persistent sexual problems, Merck has continued to provide misleading and inaccurate Propecia warnings in the United States.

According to a Reuters report, the FDA indicates that the warning label will now be updated to include information about sexual problems from Propecia that may continue after use of the drug was ended, including loss of libido, ejaculation difficulties and problems achieving an orgasm. The label will also describe reports of infertility and poor semen quality.

Despite the risks associated with this non-disease targeting medication, which is used to treat a naturally occurring phenomenon, the FDA has apparently decided not to recall Propecia as we had speculated last month. The FDA indicates that only a small percentage of men who used Propecia or Procar experienced sexual side effects, and that the medications remain safe and effective for approved use.

However, it certainly is important for men seeking to improve their appearance by regrowing hair to know that this medication may leave them with permanent sexual problems and erectile dysfunction. A number of our clients would have never used this medication if they were aware of this information.


As a result of Merck’s failure to provide adequate and sufficient warnings, financial compensation may be available through a Propecia sexual dysfunction lawsuit. Our lawyers are continuing to review potential claims for men throughout the United States and all cases are pursued under a contingency fee agreement, which means that there are no fees or expenses unless a recovery is obtained.
