Tell your doctor about all the medicines you take including prescription and non-prescription medicines, vitamins, and herbal supplements.

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Toprol falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans, though. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.

Tell your doctor if you are breastfeeding or plan to breastfeed.

Toprol has been detected in human breast milk. Because of the possibility for adverse reactions in nursing infants from Toprol, a choice should be made whether to stop nursing or to stop use of this medication. The importance of the drug to the mother should be considered.

Take Toprol exactly as prescribed.

Take Toprol at the same time each day.

Toprol comes in an extended-release tablet (metoprolol succinate). The extended-release tablet is taken once a day. Do not chew, divide, or break Toprol tablets. Swallow tablets whole.

If you miss a dose, take the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and take your next dose at the regular time. Do not take two doses of Toprol at the same time.

Take Toprol exactly as prescribed by your doctor. Follow the directions on your prescription label carefully.

The Toprol dose your doctor recommends will be based on the following:

• the condition being treated
• other medical conditions you have
• other medications you are taking
• how you respond to this medication
• your age

The recommended dose range for Toprol for treating hypertension in adults is 25 to 100 mg once a day.

The recommended dose range for Toprol for treating hypertension in children (6 years of age or older) is 0.1 mg/kg to 50 mg once a day.

The recommended dose range for Toprol for treating chest pain is 100 to 400 mg once a day.

The recommended dose range for Toprol for treating heart failure is 12.5 to 200 mg once a day.

If you take too much Toprol, call your healthcare provider or local Poison Control Center, or seek emergency medical attention right away.

• Protect from moisture and heat.
• Keep it in the original container.
• Keep this and all medications out of the reach of children.

Following abrupt cessation of therapy with certain beta-blocking agents, exacerbations of angina pectoris and, in some cases, myocardial infarction have occurred. When discontinuing chronically administered metoprolol, particularly in patients with ischemic heart disease, the dosage should be gradually reduced over a period of 1 - 2 weeks and the patient should be carefully monitored. If angina markedly worsens or acute coronary insufficiency develops, Toprol administration should be reinstated promptly, at least temporarily, and other measures appropriate for the management of unstable angina should be taken. Warn patients against interruption or discontinuation of therapy without the physician’s advice. Because coronary artery disease is common and may be unrecognized, it may be prudent not to discontinue Toprol therapy abruptly even in patients treated only for hypertension
