"WASHINGTON (Reuters) - A class of drugs meant to improve symptoms of an enlarged prostate gland actually increase the chance of getting a more serious form of prostate cancer, health officials said on Thursday.
The drugs in this group include Merck & Co's Proscar and GlaxoSmithKline's Avodar and Jalyn, as well as Merck's Propecia, which is approved to treat male pattern hair loss.
The Food and Drug Administration said it revised the labels on all such drugs, called 5-alpha reductase inhibitors (5-ARI), to include the risk after reviewing two large studies.
However, they also said the drugs' benefits outweigh the risks.
