Lawsuit Claims Hair Loss Drug Caused Health Problems

Lawsuit Claims Hair Loss Drug Caused Health ProblemsSeveral law firms have filed a dangerous drugs lawsuit against Merck & Co., alleging that the company's hair loss drug Propecia or Proscar causes the men who take it to develop mental and sexual dysfunctions that persist many years after they stop using it.

Propecia was first used to treat men with enlarged prostates, according to the Hartford Courant, but won Food and Drug Administration approval for the treatment of male pattern hair loss in 1997. However, the active ingredient, which decreases the substance on the scalp which causes hair loss, also causes severe and lasting sexual and mental side effects about which Merck did not adequately warn its customers, the suit claims.

According to one of the dangerous drugs attorneys on the case, the side effects caused by the drug in one plaintiff caused his wife to leave him, and another had to drop out of law school because of the mental impairment allegedly caused by his use of Propecia.

According to the drug's website, nine out of 10 men who took Propecia in a five-year clinical study either regrew hair or stopped losing it.
