Uses and Benefits of OLSERTAIN H 20MG TABLET (HYDROCHLOROTHIAZIDE 12.5MG + OLMESARTAN MEDOXOMIL 20MG)
This combination medicine is mainly used to treat high blood pressure (hypertension) in adults, either alone or when a single medicine is not enough to control blood pressure.
WHAT THIS MEDICINE IS USED FOR
- Managing high blood pressure (hypertension)
- Reducing the risk of heart attack, stroke, and kidney problems related to long-term high blood pressure
- Used when treatment with a single blood pressure medicine does not give enough control
HOW IT WORKS
- Olmesartan blocks a hormone called angiotensin II, which helps blood vessels relax and widen
- Hydrochlorothiazide is a diuretic (water pill) that helps the kidneys remove extra salt and water from the body
- Together, they lower the pressure on blood vessel walls, reducing blood pressure more effectively than either medicine alone
WHAT IT IS NOT USED FOR
- Not used for immediate emergency lowering of dangerously high blood pressure
- Not a painkiller or fever medicine
- Not used to treat infections
- Not recommended for use during pregnancy
- Not a cure for high blood pressure; it only controls it while taken regularly
