What Dobutamine is and what it is used for
Dobutamine belongs to a group of medicines called catecholamines. It helps your heart to work more effectively. It works by strengthening the pumping action of the heart, increasing the amount of blood flow in the body and by expanding your veins and arteries.
Dobutamine is used
- to treat heart failure (cardiac decompensation) if the heart is not beating strongly enough (depressed contractility),
- in heart failure where there is severe low blood pressure (hypotension),
- to detect poor blood supply to the heart (cardiac stress testing).
Dobutamine is indicated in all paediatric age groups (from neonates to 18 years of age) as inotropic support in low cardiac output hypoperfusion states resulting from decompensated heart failure, following cardiac surgery, cardiomyopathies and in cardiogenic or septic shock.
What you need to know before you use dobutamine
Do not use Dobutamine if
- you are allergic (hypersensitive) to Dobutamine or any of the other ingredients (see list of ingredients in section 6). An allergic reaction may include rash, itching, difficulty in breathing or swelling of the face, lips, throat or tongue. You may know this from earlier experience.
- there is a narrowing in your heart or blood vessels that prevents the heart from filling or ejecting blood properly (your doctor will know this).
- there is a lack of adequate circulatory filling (hypovolaemia).
If you have certain heart or blood vessel disorders, Dobutamine should not be used to detect poor blood supply to your heart.
Warnings and precautions
Tell your doctor if you have any of the following conditions:
- asthma and you have been told that you are allergic to sulfites,
- severe coronary heart disease,
- acute (sudden) heart failure.
Increments in heart rate and blood pressure appear to be more frequent and intense in children than in adults. The new-born baby cardiovascular system has been reported to be less sensitive to dobutamine and hypotensive effect (low blood pressure) seems to be more often observed in adult patients than in small children. Accordingly, the use of Dobutamine in children should be monitored closely.
Caution is advised in giving high doses of Dobutamine to children. Your doctor will adjust the required dose for your child carefully.
Other medicines and Dobutamine
Please tell your doctor or pharmacist if you are taking, or have recently taken, any other medicines, including medicines you can get without a prescription. This is especially important with the following medicines as they may interact with your Dobutamine:
- beta blockers (treatment of high blood pressure and irregular heart rhythms),
- alpha blockers (treatment of high blood pressure and prostate enlargement),
- vasodilators (expanding blood vessels, used to treat an angina attack or severe heart failure),
- antidiabetics (treatment of diabetes),
- ACE inhibitors (treatment of high blood pressure and heart failure),
- dopamine (used to increasing heart rate and blood pressure),
- inhaled anaesthetics.
It may still be all right for you to receive Dobutamine and your doctor will be able to decide what is suitable for you.
Pregnancy and breast-feeding
Dobutamine should not be given to pregnant women unless medically justified. It is recommended that you stop breast-feeding during your treatment with Dobutamine. Ask your doctor or pharmacist for advice before taking any medicine.
Driving and using machines
If you have any concerns ask your doctor or pharmacist.
Dobutamine contains sodium metabisulfite (E 223), which may rarely cause allergic reactions (hypersensitivity) and asthma-like symptoms (bronchospasm).
This medicinal product contains 3.05 mg sodium per 1 ml. This should be taken into consideration by patients on a controlled sodium diet.
How to use Dobutamine
Dobutamine will be given to you by specifically trained health care professionals and emergency equipment will be available.
The required rate of infusion depends on your response to therapy and any side effects. Your doctor will decide the dose of Dobutamine you will be given and will adjust the flow rate and duration of your infusion.
Dosage in adults
Most patients respond to doses of 2.5-10 micrograms of Dobutamine per kg body weight per minute. Doses up to 40 micrograms of Dobutamine per kg body weight per minute have been given.
Dosage in children
For all paediatric age groups (neonates to 18 years) an initial dose of 5 micrograms/kg/minute, adjusted according to clinical response to 2-20 micrograms/kg/minute is recommended. Occasionally, a dose as low as 0.5-1.0 micrograms/kg/minute will produce a response. The required dose for children should be titrated in order to allow for the supposedly smaller “therapeutic width” in children.
