Pericardial, pleural effusion and anasarca: A rare complication of low-dose oral minoxidil for hair loss

Abstract

Topical minoxidil has been used for many years in the treatment of androgenic alopecia and other hair disorders. Although the mechanism of action of topical minoxidil is poorly understood, animal studies have shown that it affects the hair growth cycle by shortening the telogen phase and prolonging the anagen phase.1,2 Lately, there has been growing evidence to support successful use of low-dose oral minoxidil (LDOM) in the treatment of various types of alopecia. The dosing regimens range from 0.25 to 5 mg daily to twice daily, with side effects reported to be dose dependent.
