title: Hydrochlorothiazide-induced pulmonary edema.
abstract: A patient with probable hydrochlorothiazide-induced pulmonary edema is described. A 70-year-old woman experienced nausea, diaphoresis, and severe respiratory distress approximately 1/2 hour after taking an Aldactazide tablet. She had experienced a flu-like syndrome after taking a single tablet two weeks previously. The patient was mildly tachycardic with a blood pressure of 74/0 mm Hg. A chest X-ray revealed cardiomegaly and bilateral pulmonary edema suggestive of congestive heart failure. The pulmonary capillary wedge pressure was normal. It was felt that the patient had developed a noncardiac pulmonary edema possibly secondary to hydrochlorothiazide ingestion. Nine other cases reported in the literature also are described. Pharmacists should be aware of this potential life-threatening reaction and avoid patient reexposure to the drug.
