Quebec court OK’s lawsuit alleging link between hair-loss drugs and erections
MONTREAL — Quebec’s highest court has authorized a class-action suit on behalf of men who took medication for hair loss and then allegedly suffered various problems, including erectile dysfunction.
The defendants are Merck Canada and Merck Frosst Canada, which sold the Propecia and Proscar prescription drugs.
Propecia is used mainly to treat baldness, while Proscar is used primarily to treat enlargement of the prostate. Both contain the active ingredient finasteride.
The lawsuit covers Quebec men who were prescribed one of the two drugs before Nov. 18, 2011, and then allegedly developed problems that lasted even after they stopped using them.
