Brand Name: Brevibloc
Esmolol is used for:
Temporary control of heart rate and blood pressure. It may also be used for other conditions as determined by your doctor.
Esmolol is a beta-blocker. It works by reducing the workload on the heart and helping the heart beat more regularly.
Do NOT use esmolol if:
- you are allergic to any ingredient in esmolol
- you have heart block, shock caused by serious heart problems, moderate to severe heart failure, certain types of irregular heartbeat (eg, sick sinus syndrome), a very slow heartbeat, or pulmonary hypertension
- you are taking mibefradil
Contact your doctor or health care provider right away if any of these apply to you.
Before using esmolol:
Some medical conditions may interact with esmolol. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:
- if you are pregnant, planning to become pregnant, or are breast-feeding
- if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
- if you have allergies to medicines, foods, or other substances
- if you have had an allergic reaction to another beta-blocker (eg, metoprolol)
- if you have heart problems (eg, heart blood vessel problems, heart failure, irregular heartbeat), chest pain (angina), blood flow problems, kidney problems, low blood volume, lung or breathing problems (eg, asthma, chronic obstructive pulmonary disorder [COPD]), diabetes, an overactive thyroid, or an adrenal gland tumor (pheochromocytoma)
- if you have a history of low blood sugar
Some MEDICINES MAY INTERACT with esmolol. Tell your health care provider if you are taking any other medicines, especially any of the following:
- Insulin or other diabetes medicines because the risk of low blood sugar may be increased
- Clonidine, guanfacine, or moxonidine because stopping any of these medicines suddenly can lead to a rapid increase in blood pressure
- Diltiazem, fingolimod, flecainide, mefloquine, mibefradil, or verapamil because the risk of serious heart problems may be increased
- Indomethacin because it may decrease esmolol's effectiveness
- Alfuzosin, digoxin, or prazosin because the risk of their side effects may be increased
This may not be a complete list of all interactions that may occur. Ask your health care provider if esmolol may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.

- Diabetes patients - Esmolol may hide signs of low blood sugar, such as a rapid heartbeat. Be sure to watch for other signs of low blood sugar.

Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
- If you have a history of any severe allergic reaction, talk with your doctor. You may be at risk of an even more severe allergic reaction if you come into contact with the substance that caused your allergy. Some medicines used to treat severe allergies also may not work as well while you are using esmolol.
- Lab tests, including blood electrolyte levels and blood pressure, may be performed while you use esmolol. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.

- PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using esmolol while you are pregnant. It is not known if this medicine is found in breast milk. Do not breast-feed while taking esmolol.
