What are metoprolol tablets or extended-release tablets? |
| METOPROLOL (Lopressor®, Toprol XL™) belongs to a group of medicines called beta-blockers. Beta-blockers reduce the workload on the heart and help it to beat more regularly. Metoprolol controls, but does not cure, high blood pressure (hypertension). High blood pressure may not make you feel sick, but it can lead to serious heart problems. Metoprolol also relieves chest pain (angina) and can be helpful after a heart attack. Metoprolol is also used to improve symptoms in patients with other types of heart disease. Generic metoprolol tablet are available, but not extended-release tablets. |

| What should I watch for while taking metoprolol? |
Check you heart rate and blood pressure regularly while you are taking metoprolol. Ask your prescriber or health care professional what your heart rate and blood pressure should be and when you should contact him or her.
Do not stop taking the medicine suddenly. This could lead to serious heart-related effects.
You may get drowsy or dizzy. Do not drive, use machinery, or do anything that requires mental alertness until you know how metoprolol affects you. To reduce the risk of dizzy or fainting spells, do not sit or stand up quickly. Alcohol can make you more drowsy, and increase flushing and rapid heartbeats. Therefore, it is best to avoid alcoholic drinks.
Metoprolol can affect blood sugar levels. If you have diabetes, check with your prescriber or health care professional before you change your diet or the dose of your diabetic medicine.
If you are going to have surgery, tell your prescriber or health care professional that you are taking metoprolol.
Store at room temperature between 15 and 30 degrees C (59 and 86 degrees F). Protect from moisture. Throw away any unused medicine after the expiration date. |
