Hydrochlorothiazide (HCTZ) and your teeth
Generic name: Hydrochlorothiazide · Class: Thiazide diuretic
Hydrochlorothiazide is a thiazide diuretic, one of the most prescribed blood pressure medications in the US, often combined with other classes.
HCTZ commonly causes dry mouth through its diuretic effect: increased urination and fluid loss mildly dehydrate many patients. It is also associated with rare lichenoid reactions and increased sensitivity to sun, which can affect the lips. Patients on HCTZ plus another blood pressure medication often have additive dry-mouth effects.
