President Donald Trump has a secret that he doesn’t want anyone to know about. Apparently, he’s taking a prostate drug that is often prescribed for hair loss, according to his physician, Dr. Harold Bornstein, in a New York Times interview. Bornstein said that the president is also taking antibiotics for rosacea, which is a skin condition characterized by excessive redness in certain areas.

The revelation is very different from what Bornstein said during the campaign, when he said that Trump was only taking rosuvastatin and low-dose aspirin to reduce the risk of a heart attack. Bornstein became famous for stating during the campaign that Trump would be the “healthiest individual ever elected to the presidency.”

The drug in question is called propecia, which is a formulation of finasteride prescribed to men with enlarged prostate clans. The FDA approved the drug to reduce the need for surgery from an enlarged prostate, but in 1997 the FDA approved it for treatment of male pattern hair loss.

The FDA’s statement on Propecia: “On April 11, 2012, the U.S. Food and Drug Administration (FDA) announced changes to the professional labels for Propecia (finasteride 1 mg) and Proscar (finasteride 5 mg) to expand the list of sexual adverse events reported to FDA as some of these events have been reported to continue after the drug is no longer being used (note that erectile dysfunction after stopping use of these drugs was added as a known event in 2011). The new label 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.”
