What Is Hydrochlorothiazide 12.5mg?
Hydrochlorothiazide is a prescription thiazide diuretic, commonly called a water pill. It works by helping the kidneys remove excess salt and water from the body through urine, which lowers blood pressure and reduces swelling. Doctors prescribe hydrochlorothiazide for high blood pressure (hypertension), either alone or alongside other blood pressure medicines. It is also used to treat edema associated with heart failure, kidney disease, liver cirrhosis, and certain medications such as corticosteroids and estrogen.
