What is Hydrochlorothiazide (HCTZ)?

Hydrochlorothiazide (HCTZ) is a prescription medication for treating hypertension or high blood pressure and edema (water retention). It is available in the market as Aquazide H, Microzide, Hydrocot, and Zide. Hydrochlorothiazide (HCTZ) belongs to the thiazide diuretic class of medication.
