(WASHINGTON) -- The U.S. Food and Drug Administration is updating the warning label information on a group of drugs, including Avodart and Proscar, which are used to shrink the prostate.
The FDA says these drugs, which can reduce the risk of some forms of prostate cancer, may increase the risk of a more serious form of the disease for some men. The agency is basing its conclusions on a review of two large studies in which about 27,000 men aged 50 and older used the drugs for several years.
The FDA says the risk of high-grade prostate cancers is small, but doctors should be aware of it.
The drugs Avodart and Proscar are also known as dutasteride and finasteride, respectively.
Also from this group of drugs, and also included in this warning, is the drug Propecia, which is used to treat male pattern hair loss.
If you or someone you know is using these three drugs and has experienced adverse events, tell your doctor. The FDA would also like to hear from you. You can report your experience by going to the Food and Drug Administration website, or by calling the FDA.
