The Food and Drug Administration (FDA) announced recently that they have added new warnings to finasteride, the drug used to treat male pattern baldness and enlarged prostate.

Labels for Propecia and Proscar now include an expanded list of sexual adverse events reported to the FDA, citing some side effects events have continued after the drug is no longer being used by a patient.

According to their website, the changes include:

• A revision to the Propecia label to include libido disorders, ejaculation disorders, and orgasm disorders that continued after discontinuation of the drug.
• A revision to the Proscar label to include decreased libido that continued after discontinuation of the drug.
• A revision to both the Propecia and Proscar labels to include a description of reports of male infertility and/or poor semen quality that normalized or improved after drug discontinuation.

The site also says, “Despite the fact that clear causal links between finasteride (Propecia and Proscar) and sexual adverse events have NOT been established, the cases suggest a broader range of adverse effects than previously reported in patients taking these drugs.”

Dr. Drew noted on his HLN show Thursday night, “We don't know how long before the side effects go away. I presume they will, [but] we just don’t know. So think long and hard and then talk to your doctor about these medications.”
