It works by increasing the amount of urine the kidneys produce, which helps to remove excess water and salt from the body. Hydrochlorothiazide can be used alone or in combination with other medications to lower blood pressure.
It is a type of thiazide diuretic, and works by blocking the reabsorption of sodium and chloride in the kidneys, which leads to increased excretion of water and sodium in the urine.
This medication may also be used to treat certain kidney disorders and diabetes insipidus, a rare condition in which the body produces too much urine.
Hydrochlorothiazide is available as a generic medication and under the brand name Microzide.
