Hydrochlorothiazide, sold under the brand name Hydrodiuril among others, is a diuretic medication used to treat hypertension and swelling due to fluid build-up.[3] Other uses include treating diabetes insipidus and renal tubular acidosis and to decrease the risk of kidney stones in those with a high calcium level in the urine.[3] Hydrochlorothiazide is taken by mouth and may be combined with other blood pressure medications as a single pill to increase effectiveness.[3] Hydrochlorothiazide is a thiazide medication which inhibits reabsorption of sodium and chloride ions from the distal convoluted tubules of the kidneys, causing a natriuresis.[3][4] This initially increases urine volume and lowers blood volume.[5] It is believed to reduce peripheral vascular resistance.[5]
Potential side effects include poor kidney function, electrolyte imbalances, including low blood potassium, and, less commonly, low blood sodium, gout, high blood sugar, and feeling lightheaded with standing.[3]
Two companies, Merck & Co. and Ciba Specialty Chemicals, state they discovered the medication which became commercially available in 1959.[6] It is on the World Health Organization's List of Essential Medicines.[7] It is available as a generic drug[3] and is relatively affordable.[8] In 2022, it was the twelfth most commonly prescribed medication in the United States, with more than 38 million prescriptions.[9][10]
