Hydrochlorothiazide (HCTZ) is a thiazide diuretic commonly used as a first-line medication for hypertension. It works by helping the kidneys remove excess sodium and water, which lowers blood volume and reduces blood pressure. HCTZ is generally well-tolerated and is often included in combination pills with other antihypertensive agents. Possible side effects include low potassium, dizziness, and increased urination. It’s especially effective in older adults and those with salt-sensitive hypertension.
