President Trump takes medication for three ailments, including a prostate-related drug to promote hair growth, Mr. Trump’s longtime physician, Dr. Harold N. Bornstein, said in a series of recent interviews.

The other drugs are antibiotics to control rosacea, a common skin problem, and a statin for elevated blood cholesterol and lipids.

Dr. Bornstein, who spoke by telephone in four interviews over the past month, also said that Mr. Trump takes a daily baby aspirin to reduce the risk of a heart attack. Over all, he pronounced Mr. Trump healthy and his medical care “as exactly up to date.”
