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.”

Dr. Bornstein granted the interviews after The New York Times asked him to discuss his role in Mr. Trump’s care and to clarify and expand on earlier statements he made about his patient’s health during the presidential campaign. In recent decades, The Times has interviewed presidents, presidential candidates and their doctors about their health. At 70, Mr. Trump is the oldest person to become president.
