The Hydrochlorothiazide FDA package insert doesn’t have numbers about how common side effects are.
More about Hydrochlorothiazide side effects » How it works Losartan Hydrochlorothiazide Cozaar (Losartan) is an angiotensin receptor blocker (ARB). It blocks a chemical that tightens blood vessels. This makes blood vessels relax, which lowers blood pressure and allows more blood and oxygen to get to your heart and other organs. Microzide (Hydrochlorothiazide (Hctz)) is a thiazide diuretic (water pill). It works in the kidneys to make you urinate more, which removes extra water and certain electrolytes. This lowers blood pressure and swelling. Type of medication Losartan Hydrochlorothiazide Antihypertensive
