A Rare Case of Pulmonary Edema Secondary to Hydrochlorothiazide Use.

Noncardiogenic pulmonary edema has been reported as a rare adverse reaction of hydrochlorothiazide. Symptoms can develop acutely after medication ingestion, and patients may present acutely ill. The mechanism by which hydrochlorothiazide causes pulmonary edema remains unknown and is considered idiosyncratic. Prompt supportive care and discontinuation of the medication is necessary to prevent and manage such a complication. This case report describes a patient who developed noncardiogenic pulmonary edema after taking a combination pill of hydrochlorothiazide-losartan.
