What is in this leaflet

All medicines have risks and benefits. Your doctor has weighed the risks of you being given Dobutrex against the benefits they expect it will have for you.
If you have any concerns about being given this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine. You may need to read it again.
What Dobutrex is used for
This medicine contains dobutamine (as dobutamine hydrochloride) as the active ingredient. It belongs to a group of medicines called catecholamines, which are a synthetic version of a naturally occurring chemical, adrenaline.
Dobutrex is used to treat patients who need short-term treatment of heart failure following a heart attack or heart surgery.
It works by strengthening the pumping action of the heart, increasing the amount of blood flowing to the body and by expanding both veins and arteries, so the heart can more easily propel the blood. It helps your heart work more effectively.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.
This medicine is only available with a doctor’s prescription.
There is no evidence that it is addictive.
There is not enough safety and efficacy information available to recommend the use of Dobutrex in children.

You must not be given this medicine if you have a condition called idiopathic hypertrophic sub aortic stenosis (i.e. a narrowing of the artery coming from your heart).

How it is given
Dobutrex is a sterile powder which is dissolved and diluted with suitable sterile fluids. It is given as a slow injection into a vein, known as a continuous infusion or a ‘drip’.
Your doctor or nurse will prepare the infusion of Dobutrex for you.
How much to be given
Your doctor will decide the dose of Dobutrex you will be given and will adjust the flow rate and duration accordingly.
If you are given too much (overdose)
As you will be given Dobutrex under the supervision of your doctor, it is unlikely that you will receive too much.
However, if you experience any side effects after being given Dobutrex, immediately tell your doctor or nurse or call the Poisons Information Centre (telephone 13 11 26) for advice.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
