Key takeaways
Tenoretic (atenolol/chlorthalidone) and metoprolol/hydrochlorothiazide are both combination medications used to lower blood pressure, but they have some differences. Tenoretic combines atenolol, a cardioselective beta blocker, with chlorthalidone, a thiazide-like diuretic. Metoprolol/hydrochlorothiazide combines metoprolol tartrate, another cardioselective beta blocker, with hydrochlorothiazide, a thiazide diuretic. Tenoretic is typically taken once daily, while metoprolol/hydrochlorothiazide can be taken once or twice daily with food. Both medications can cause dizziness, tiredness, nausea, and slow heartbeat. Additionally, Tenoretic is not safe for use during pregnancy or breastfeeding, while metoprolol/hydrochlorothiazide has similar warnings but also includes a risk of eye problems and lupus. Both medications should not be stopped suddenly due to the risk of heart problems.
