1. what brevibloc is and what it is used for

Brevibloc contains a medicine called esmolol. It belongs to a group of medicines called ‘beta-blockers’. It works by controlling the rate and force of your heartbeat. It can also help to reduce your blood pressure.

It is used to treat:

• Heartbeat problems, when your heart beats too fast
• Heartbeat problems and an increase in your blood pressure if this happens during or straight after an operation.

2. what you need to know before you are given brevibloc

Your doctor will not give you Brevibloc if:

• You are allergic (hypersensitive) to esmolol, to other beta-blocker medicines, or any of the other ingredients of this medicine (listed in section 6).

The signs of an allergic reaction include shortness of breath, wheezing, rash, itching or swelling of your face and lips

• You have a very slow heartbeat (less than 50 beats per minute)
• You have a fast or alternating fast and slow heartbeat
• You have something called “severe heart block”. Heart block is a problem with the electrical messages that control your heartbeat
• You have low blood pressure
• You have a problem with the blood supply to your heart
• You have serious heart failure symptoms
• You are receiving or have recently received verapamil. You must not be given Brevibloc within 48 hours of when you stop receiving verapamil
• You have a gland disease called phaeochromocytoma which has not been treated. Phaeochromocytoma arises from the adrenal gland and may cause a sudden increase in blood pressure, severe headache, sweating and increased heartbeat
• You have increased blood pressure in the lungs (pulmonary hypertension)
• You have asthma symptoms that are worsening rapidly
• You have increased levels of acids in your body (metabolic acidosis).

You will not be given Brevibloc if any of the above applies to you. If you are not sure if you have any of these conditions, talk to your doctor, nurse or pharmacist before having Brevibloc.

Warnings and Precautions

Talk to your doctor, nurse or pharmacist before being given Brevibloc. Your doctor will take special care with this medicine if:

• You are being treated for certain heart rhythm disorders called supraventricular arrhythmias and you:

• – Have other heart problems or

• – Are taking other heart medicines

Use of Brevibloc in this way can lead to severe reactions which may be fatal including:

• – Loss of consciousness

• – Shock (when your heart does not pump enough blood)

• – Heart attack (cardiac arrest)

• You develop low blood pressure (hypotension). The signs of this may be feeling dizzy or light headed, especially when standing up. Low blood pressure usually gets better within 30 minutes of the end of your Brevibloc treatment
• You have a low heart rate before treatment
• Your heart rate decreases to less than 50 to 55 beats per minute. If this happens your doctor may give you a lower dose or stop treatment with Brevibloc
• You have heart failure
• You have problems with the electrical messages that control your heartbeat (heart block)
• You have a gland disease called phaeochromocytoma which has been treated with medicines called alpha-receptor blockers
• You are being treated for high blood pressure (hypertension) which has been caused by low body temperature (hypothermia)
• You have narrowing of your airways or wheezing, such as with asthma
• You have diabetes or low blood sugar. Brevibloc can increase the effects of your diabetes medicines
• You develop skin problems. These can be caused by the solution leaking around the site of the injection. If this happens your doctor will use a different vein for your injection
• You have a particular type of angina (chest pain) called ‘Prinzmetal’s an­gina’
• You have low blood volume (with low blood pressure). You could develop circulatory collapse more easily
• You have circulation problems, such as paleness of your fingers (Raynaud’s disease) or aching, tired and sometimes burning pains in your legs
• You have kidney problems. If you have kidney disease or you need kidney dialysis you could develop high blood potassium levels (hyperkalemia). This can cause serious heart problems
• You have any allergies or are at risk of anaphylactic reactions (severe allergic reactions). Brevibloc can make allergies more severe and more difficult to treat
• You or any of your family have a history of psoriasis (where your skin produces scaly patches)
• You have a disease called hyperthyroidism (an overactive thyroid gland).

Changing the dose is not usually necessary if you have liver problems.

If any of the above apply to you (or you are not sure), talk to your doctor, nurse or pharmacist before being given this medicine. You may need to be checked carefully and your treatment may be changed.

Other medicines and Brevibloc

Tell your doctor, nurse or pharmacist if you are taking, have recently taken or might take any other medicines.

If you are not sure if any of the above applies to you talk to your doctor, nurse or pharmacist before having Brevibloc.

Tests you may have while Brevibloc is used

The use of medicines such as Brevibloc over a long period of time can cause a reduction in the force of your heartbeat.

Since Brevibloc is only used for a limited time, this is unlikely to happen to you. During treatment you will be carefully monitored and Brevibloc treatment will be reduced or stopped if the force of your heartbeat is reduced.

Your doctor will also check your blood pressure while you are being treated with Brevibloc.

Pregnancy and breast-feeding

Ask your doctor or pharmacist for advice before taking any medicine.

You should not be given Brevibloc if you are pregnant, or if you think you may be pregnant.

Tell your doctor if you are breast-feeding. Brevibloc may pass into breast milk, so you should not be given Brevibloc if you are breast-feeding.

Brevibloc contains sodium

Brevibloc contains approximately 28 mg of sodium per vial. This may be important if you are controlling the sodium in your diet.

3. How you will be given Brevibloc

The recommended dose

Your doctor will decide how much of the medicine you will need and for how long it will be given to you. Brevibloc will not normally be given for longer than 24 hours.

How Brevibloc is given

Brevibloc is ready to use. You will be given Brevibloc by a slow injection (infusion) through a needle inserted into a vein in your arm.

Brevibloc must not be mixed with sodium bicarbonate or other medicinal products.

• The treatment is given in two stages:

• – Stage one: a large dose is given over one minute. This increases the levels in your blood quickly

• – Stage two: a smaller dose is then given over four minutes

• – Stage one and two may then be repeated and adjusted according to your heart’s response. As soon as an improvement has happened, stage one (the large dose) will be stopped and stage two (the small dose) will be reduced as necessary

• – After reaching a stable condition, you may be given another heart drug, while your dose of Brevibloc is gradually reduced.

• If your heart rate or blood pressure increases during an operation or straight after recovering from it, you will be given larger doses of Brevibloc for a short time.

The Elderly

Your doctor will start your treatment with a lower dose.

Children

Children up to the age of 18 years should not receive Brevibloc.

If you have too much Brevibloc

As you are being given Brevibloc by a trained and qualified person, it is unlikely that you will have too much. However, if this happens the doctor will stop Brevibloc and give you additional treatment, if necessary.

If you think that a dose of Brevibloc has been forgotten

As you are being given Brevibloc by a trained and qualified person, it is unlikely that you will miss a dose. However, if you think that you have missed a dose, talk to your doctor, nurse or pharmacist as soon as possible.

If you stop having Brevibloc

Suddenly stopping Brevibloc may cause symptoms of rapid heartbeat (tachycardia) and high blood pressure (hypertension) to return. To avoid this your doctor should stop your treatment gradually. If you are known to have coronary artery disease (this may be associated with a history of angina or heart attack) your doctor will take special care when stopping treatment with Brevibloc.

If you have any further questions on the use of this product ask your doctor, nurse or pharmacist.
