An intensive-care drip to support blood pressure
Dopamine
A drip given in intensive care to support blood pressure and heart output in shock.
What is Dopamine?
Dopamine is a medicine given as a drip into a vein in hospital, usually in intensive care, to support blood pressure and the heart's pumping in people who are seriously ill with shock. It is a natural body chemical that, given in this way, helps the heart beat more strongly and tightens blood vessels to keep blood pressure up. It is given through a pump with continuous monitoring, because it can cause a fast or irregular heartbeat and because, if it leaks out of the vein into surrounding tissue (extravasation), it can damage that tissue. It is only used by specialist hospital teams.
Education and reference only. This is a plain-language guide to Dopamine — 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
Dopamine is a chemical the body makes naturally, but as a medicine it is given as a controlled drip into a vein to support seriously ill patients, almost always in an intensive care or high-dependency setting. It is used to help maintain blood pressure and to support the heart's pumping when the circulation is failing, for example in shock. It is not a medicine people take at home; it is given and adjusted continuously by specialist teams using a pump, with close monitoring of the heart and blood pressure throughout.
How it works
Given as a drip, dopamine acts on the heart and blood vessels. It can make the heart pump more strongly and faster, and it can tighten blood vessels, both of which help raise and support blood pressure when the circulation is failing. Because its effects depend closely on how fast it is given, it is delivered through a pump and adjusted carefully while the patient is monitored. The same actions that support the circulation can also cause a fast or irregular heartbeat, which is one reason continuous monitoring is essential.

Practical use
How to take Dopamine
General, dose-free guidance — always follow your prescriber's and the leaflet's specific instructions.
- It is given by the hospital team as a controlled drip into a vein, not taken by mouth.
- It is delivered through a pump and adjusted continuously while the heart and blood pressure are monitored.
- It is usually given through a large, secure line to lower the risk of it leaking into surrounding tissue.
- The drip site is checked regularly for any sign of leakage, which can damage tissue.
- All dosing and changes are managed by the specialist intensive-care team.
Weighing it up
Advantages & disadvantages of Dopamine
Advantages
- Helps support blood pressure and the heart's pumping in seriously ill patients with shock.
- Can be adjusted quickly through a pump in response to the patient's condition.
- A well-established option for circulatory support in intensive care.
Disadvantages
- Can cause a fast or irregular heartbeat, needing continuous heart monitoring.
- Can cause serious tissue damage if it leaks out of the vein (extravasation).
- Can only be given in hospital, by a specialist team, through a pump.
Practical use
Good to know
Dopamine is an intensive-care medicine, so most of what matters about it concerns how the hospital team gives it safely rather than anything a patient does themselves. It is given through a pump into a vein and adjusted continuously, with the heart rhythm and blood pressure watched closely. Two practical safety points stand out. First, it can cause a fast or irregular heartbeat, so the heart trace is monitored throughout. Second, if it leaks out of the vein into the surrounding tissue, a problem called extravasation, it can cause serious tissue damage, which is why it is usually given through a large, secure line and the site is checked regularly. Families can be reassured that its use, dosing and adjustment are all managed by the specialist team.
Who should not take it / use with caution
- It is not suitable for people with certain fast or abnormal heart rhythms unless these are treated first.
- It is used with great caution in people with a tumour of the adrenal gland (phaeochromocytoma).
- It is only ever used in hospital under specialist supervision with monitoring.
- People who have had a serious reaction to it should not be given it.
Monitoring
- Continuous monitoring of the heart rhythm and blood pressure while it is being given.
- Regular checks of the drip site for any sign of leakage into surrounding tissue.
- Close review of the overall circulation and response, with the drip adjusted as needed.
Side effects
- A fast or irregular heartbeat, which is monitored continuously.
- Headache, nausea or palpitations.
- Tissue damage at the drip site if the medicine leaks out of the vein.
- Changes in blood pressure that the team adjusts the drip to manage.
Key interactions
- It can interact with several other heart and blood-pressure medicines, which the team takes into account.
- Certain antidepressants and other medicines can change its effects, so the team reviews everything the patient takes.
- Its use is carefully balanced with other intensive-care treatments.
Available as: A solution given as a controlled drip into a vein in hospital.

What is dopamine used for?
As a medicine, it is given by drip in hospital intensive care to support blood pressure and the heart's pumping in people who are seriously ill with shock.

No. This medicine is given only as a controlled drip into a vein in hospital, delivered through a pump and adjusted by the specialist team.
Why is it given through a pump with monitoring?
Its effects depend closely on how fast it is given, and it can cause a fast or irregular heartbeat, so it is delivered and monitored carefully.
What is extravasation?
It means the medicine leaking out of the vein into the surrounding tissue, which can cause serious tissue damage, so the drip site is checked regularly.
Can it be given at home?
No. Dopamine is an intensive-care medicine given only in hospital by a specialist team with continuous monitoring.
