Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Metoprolol succinate (Toprol XL) and clonidine (Catapres, Nexiclon XR) are both used to manage high blood pressure, but they work differently and have different uses. Metoprolol succinate is a selective beta blocker that mainly affects the heart, slowing down your heart rate and lowering blood pressure. It is also used to treat chest pain and reduce the risk of hospitalization and death in heart failure. Clonidine, on the other hand, is an alpha agonist that works in the brain to lower stress hormones, which slows your heart rate and relaxes blood vessels. Clonidine is available in oral and topical forms, while metoprolol succinate is taken orally. Clonidine is not usually a first-choice treatment for high blood pressure because it can cause rebound hypertension if stopped suddenly, and it is not recommended for older adults due to the risk of falls. Metoprolol succinate is typically taken once daily with food, whereas clonidine can be taken as a tablet multiple times a day or applied as a patch once a week. Both medications can cause dizziness and tiredness, but clonidine is more likely to cause dry mouth and drowsiness.

Summary of Toprol XL vs. Catapres-TTS
Summary for Beta blocker
Prescription only
Metoprolol succinate (Toprol XL) is used to treat hypertension and to control chronic (long-term) chest pain. It's also used to lower the risk for hospitalization and death in people with heart failure. Metoprolol succinate (Toprol XL) is the extended-release version of metoprolol tartrate (Lopressor), but keep in mind the two versions don't treat the exact same conditions. And because metoprolol succinate (Toprol XL) is longer-acting, it's taken by mouth typically taken just once daily. Some common side effects of metoprolol succinate (Toprol XL) include tiredness or dizziness.
Summary for Alpha agonist
Prescription only
Clonidine is a prescription medication that can be used to treat high blood pressure. It comes in 3 forms: topical patch, immediate-release tablet, and extended-release tablet. Clonidine usually isn't a first-choice option to treat high blood pressure because it can cause "rebound hypertension" (sudden rise in blood pressure) when the medication is suddenly stopped. Clonidine also isn't recommended for older adults since it can raise the risk for falls.
