An intravenous medicine to support a failing heart
Dobutamine
An intravenous medicine used in hospital to make a failing or weakened heart pump more strongly.
What is Dobutamine?
Dobutamine is a hospital-only medicine that helps a struggling or weakened heart pump more strongly. It is given as a continuous drip into a vein and is used in seriously unwell patients, such as those with severe heart failure or shock, or sometimes during certain heart tests. It works by stimulating the heart, so the heart beats more forcefully but can also beat faster or develop an irregular rhythm, and it raises how much oxygen the heart needs. For these reasons it is only given in a hospital setting with close monitoring of the heart rhythm and blood pressure.
Education and reference only. This is a plain-language guide to Dobutamine — it deliberately contains no doses. Doses depend on the person, the brand and the reason for treatment, and belong with your prescriber. Always check the BNF, the product labelling (SmPC) and follow medical advice.
What it is
Dobutamine is a medicine used in hospital to support the heart when it is not pumping well enough on its own, for example in severe heart failure or in some forms of shock. It belongs to a group of medicines called inotropes, which strengthen the heart's pumping. It is given only as a drip into a vein, usually in a high-dependency or intensive-care setting, and is sometimes also used during a specialised heart scan to see how the heart responds to extra workload. It is not a medicine that people take at home.
How it works
Dobutamine stimulates receptors in the heart muscle that make each heartbeat more forceful, so the heart pumps a greater amount of blood with each contraction. This can improve blood flow around the body when the heart is failing or under strain. Because it stimulates the heart, it can also speed up the heart rate and, in some people, trigger an irregular rhythm, and it increases how much oxygen the heart muscle uses. It acts quickly and wears off quickly once the drip is slowed or stopped, which lets the team adjust the effect closely while watching the heart.

How to take Dobutamine
General, dose-free guidance — always follow your prescriber's and the leaflet's specific instructions.
- It is given only in hospital, as a continuous drip into a vein, by trained staff.
- The rate of the drip is adjusted carefully based on how the heart and blood pressure respond.
- The heart rhythm and blood pressure are watched continuously while it is running.
- It is used for as short a time as the situation allows, then gradually reduced.
- It is never something a patient adjusts or takes themselves.
Weighing it up
Advantages & disadvantages of Dobutamine
Advantages
- Helps a failing or weakened heart pump more strongly in a serious situation.
- Acts quickly and wears off quickly, so its effect can be finely adjusted.
- Can improve blood flow around the body when the heart is struggling.
Disadvantages
- Can speed up the heart or cause an irregular heart rhythm.
- Makes the heart work harder and use more oxygen.
- Can only be given in hospital with continuous monitoring.
Practical use
Good to know
Dobutamine is very much a hospital medicine, given as a carefully controlled drip and adjusted minute by minute according to how the patient responds. The main thing to understand is the trade-off: while it helps a weak heart pump more strongly, it also makes the heart work harder and use more oxygen, and it can cause a fast or irregular heartbeat. That is why it is always used with continuous monitoring of the heart rhythm and blood pressure, and why the dose is kept to what is needed. It can raise or, in some cases, lower blood pressure, and may cause palpitations, chest discomfort or headache. The team weighs its benefits in keeping blood flowing against these risks, and uses it for as short a time as the situation allows.
Who should not take it / use with caution
- People who have had a serious allergic reaction to dobutamine should not be given it.
- It is used with great care in certain heart conditions where stimulating the heart could be harmful.
- It is only ever given under specialist supervision with continuous heart monitoring.
Monitoring
- Continuous monitoring of the heart rhythm while it is running.
- Close watching of blood pressure and how well blood is flowing around the body.
- Regular review of whether it is still needed and adjusting the drip accordingly.
Side effects
- A faster heartbeat or palpitations.
- An irregular heart rhythm in some people.
- Chest discomfort, headache, nausea or changes in blood pressure.
Key interactions
- Other medicines that affect the heart rate or rhythm may add to its effects, so they are reviewed by the team.
- Some blood-pressure medicines, including certain beta-blockers, can change how it works.
- Because it is used in intensive settings, all of a patient's medicines and drips are considered together.
Available as: A solution given as a drip into a vein in hospital.
Answers
Dobutamine: frequently asked questions
What is dobutamine used for?
It is a hospital medicine used to help a failing or weakened heart pump more strongly, for example in severe heart failure or shock, and sometimes during a specialised heart scan.
How is it given?
It is given only in hospital as a continuous drip into a vein, with the rate carefully adjusted by trained staff.
Why does it need close monitoring?
Because it stimulates the heart it can speed up the heart rate or cause an irregular rhythm and makes the heart use more oxygen, so the heart rhythm and blood pressure are watched continuously.
Can I take it at home?
No. Dobutamine is only given in a hospital setting under close supervision; it is never taken at home.
How quickly does it work?
It acts quickly and also wears off quickly once the drip is slowed or stopped, which lets the team fine-tune its effect.
