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.

Some of the symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin.
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

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.
