TLDR Minoxidil can cause heart inflammation, so users should be monitored.
A 53-year-old man developed recurrent pericardial effusions and pericarditis after using low-dose minoxidil for hair growth, despite no prior heart or kidney issues. Symptoms appeared within 20 days of starting minoxidil and resolved after discontinuation, indicating a likely causal link. The study suggests routine evaluation for pericardial disease in minoxidil users and highlights the role of multimodal imaging in managing such complications.
Stopping minoxidil and draining fluid around the heart can save lives in rare cases.
