Key takeaways
Hydrochlorothiazide (Microzide) and Tenoretic (atenolol/chlorthalidone) are both used to lower blood pressure, but they belong to different medication classes. Hydrochlorothiazide is a thiazide diuretic, also known as a water pill, that helps you urinate more to remove extra fluid and certain electrolytes from your body. Tenoretic, on the other hand, is a combination of a beta blocker (atenolol) and a thiazide-like diuretic (chlorthalidone). While both medications help lower blood pressure, Tenoretic also slows down your heart rate due to the beta blocker component. Doses of hydrochlorothiazide can be adjusted based on your response, while Tenoretic is a fixed-dose combination, making it harder to adjust the dose. Additionally, Tenoretic is not recommended for pregnant or breastfeeding individuals, while hydrochlorothiazide requires caution but does not have the same strict contraindications. Both medications are available as lower-cost generics and can cause you to urinate more often and may make your skin more sensitive to sunlight.
