Hydrochlorothiazide

Hydrochlorothiazide is a thiazide diuretic, or water pill, used to help the body remove extra salt and water. It may also help relax blood vessels, which can lower blood pressure.

It is commonly prescribed for high blood pressure and fluid retention. Take it exactly as directed, and tell your clinician if you have kidney disease, gout, diabetes, or low potassium, or if you become dehydrated.
