[Massive pericardial effusion following minoxidil].

Area of Science:

• Cardiology
• Pharmacology

Background:

• Minoxidil is a potent antihypertensive medication used for severe cases.
• The patient presented with symptoms of severe hypertension, including dyspnea and peripheral edema.

Observation:

• A 58-year-old male patient was undergoing evaluation for progressive dyspnea and peripheral edema.
• The patient was concurrently taking Minoxidil, Normiten, and Lasix for severe hypertension.
• Echocardiography revealed a massive pericardial effusion without signs of cardiac tamponade.

Findings:

• Discontinuation of Minoxidil treatment resulted in the complete clearance of pericardial fluid over a 3-month period.
• This suggests a direct causal link between Minoxidil use and the development of pericardial effusion.

Implications:

• Minoxidil's potential to cause pericardial effusion, a serious side effect, must be recognized by healthcare professionals.
• This finding underscores the importance of vigilant monitoring for cardiovascular complications in patients treated with Minoxidil.
• Early recognition and management, including drug discontinuation, can prevent potentially fatal outcomes associated with Minoxidil-induced pericardial effusion.
