Toprol-XL (metoprolol succinate) is a beta-blocker that affects the heart and circulation (blood flow through arteries and veins).
Toprol-XL is used to treat angina (chest pain) and hypertension (high blood pressure).
Toprol-XL is also used to lower your risk of death or needing to be hospitalized for heart failure.
You should not use Toprol-XL if you have a severe heart block (greater than first degree), sick sinus syndrome without a pacemaker, severe circulation problems, severe heart failure, a history of slow heart beats that caused fainting, or if you are allergic to Toprol-XL or metoprolol.
Tell your doctor about all medications you are taking before using Toprol-XL, especially any calcium channel blockers (including diltiazem, verapamil, and others).
Take Toprol-XL exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.
Toprol-XL should be taken with a meal or just after a meal.
Take the medicine at the same time each day.
Swallow the extended release tablet whole and do not crush or chew the tablet.
A Toprol XL tablet can be divided in half if your doctor has told you to do so. Swallow the half-tablet whole, without chewing or crushing.
You will need frequent medical tests, and your blood pressure will need to be checked often.
If you need surgery, tell the surgeon ahead of time that you are using metoprolol.
You should not stop using Toprol-XL suddenly. Stopping suddenly may make your condition worse.
If you have high blood pressure, keep using Toprol-XL even if you feel well. High blood pressure often has no symptoms. You may need to use metoprolol for the rest of your life.
