“The FDA-approved pill has been called into question, with emerging research and a slew of lawsuits suggesting that finasteride may be more dangerous than previously believed,” reported Men’s Journal. “Users report that its side effects — inability to orgasm, painful erections, chronic depression, insomnia, brain fog, and suicidal thoughts — can last long after patients stop taking the pill.”

Since 2011, at least 1,245 lawsuits have been filed against Propecia’s manufacturer, Merck, alleging that the company didn’t sufficiently warn users of sexual and cognitive side effects. Patients and physicians reportedly call the effects “Post-Finasteride Syndrome” because, they say, symptoms often persist after discontinuing the drug. The National Institutes of Health has added PFS to its rare-diseases database. Merck told Men’s Journal the the company “stands behind the demonstrated safety and efficacy profile of Propecia.”

And of course, the disclosure about the president taking Propecia spurred many to ask: What other drugs does he take? The Washington Post noted that Trump had multiple opportunities to mention his Propecia use, but didn’t.
