Minoxidil-Induced Pleuro-Pericardial Effusion With Tamponade.

Minoxidil-induced pleuro-pericardial effusion is a diagnosis of exclusion after evaluation for other known causes of pericardial effusion. When complicated by cardiac tamponade, prompt pericardiocentesis and discontinuation of minoxidil can be lifesaving. We report a rare case of minoxidil-induced pleuro-pericardial effusion with tamponade in a patient with end-stage renal disease (ESRD) on hemodialysis who improved with pericardiocentesis and drug withdrawal.
