Two Merck drugs for treating male baldness and enlarged prostate will now carry extended labels to add more possible sexual side effects, US regulators said on Friday.The changes involve Propecia and Proscar, both of which contain the active ingredient finasteride
The new Propecia label will include "libido disorders, ejaculation disorders, and orgasm disorders that continued after discontinuation of the drug," the FDA said. Propecia is a drug to treat male baldness.
Proscar, which treats symptoms of enlarged prostate, will now have a label that adds "decreased libido that continued after discontinuation of the drug."
In addition, both labels are being revised to "include a description of reports of male infertility and/or poor semen quality that normalized or improved after drug discontinuation," the FDA said.
