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 Trump takes a baby aspirin to reduce the risk of a heart attack.
At 70, Trump is the oldest person to become president. White House officials declined to comment on the information provided by Dr. Bornstein, and would not say whether he was still Trump’s physician. The disclosure that Trump uses a prostate-related drug to maintain growth of his scalp hair, which is not publicly known, appears to solve a riddle of why Trump has a very low level of prostate specific antigen.
Dr. Bornstein said he also took finasteride and credited it for helping maintain his own shoulder length hair and Trump’s hair.
“He has all his hair,” Bornstein said.
Bornstein said that Trump had gone to his East Side office for annual checkups, colonoscopies, and other routine tests every year since 1980. Before that, he was a patient of Dr. Bornstein’s father, Dr Jacob Bornstein.
