Hydrochlorothiazide (HCTZ) lowers blood pressure by lowering the amount of fluid pumping through blood vessels. It does this by increasing the amount of urine produced. Over time, HCTZ also relaxes blood vessel walls, which also helps lower blood pressure.
When you have high blood pressure, there is too much pressure in your body’s blood vessels. Over time, this high pressure can cause damage to your organs such as your heart, brain, and kidneys.
HCTZ is a type of drug called a thiazide diuretic. Diuretics are sometimes called “water pills.” They increase the amount of urine you make, especially when you first start them. This lowers the amount of salt and water in your body. By lowering the amount of fluid pumping through your blood vessels, HCTZ lowers your blood pressure.
Over time, HCTZ allows your blood vessels to relax and widen. This allows blood to flow more easily and leads to lower blood pressure.
Less Pressure, More Health!
