Lisinopril
NHS information about the medicine lisinopril, including what it's used for, who can take it, how to take it and side effects.
What lisinopril is for
Lisinopril is a type of medicine called an ACE inhibitor which makes your blood vessels relax and widen. This helps to lower your blood pressure and makes it easier for your heart to pump blood around your body.
Lisinopril is used to treat:
- high blood pressure (hypertension)
- a recent heart attack
- kidney problems caused by diabetes
It’s also used, along with other medicines, to treat heart failure.
How to take lisinopril
Lisinopril comes as tablets you swallow with water, or as a liquid.
Your doctor may prescribe a low dose to start with and gradually increase it over a few days or weeks. This reduces the chances of side effects.
You may have regular blood tests or other checks while you're taking lisinopril.
Some people take it for a few weeks while others take it for several months or more.
When taking lisinopril:
- try to take it at the same time each day
- swallow the tablets whole with a glass of water
Always check the packet or leaflet that comes with your medicine. Ask a pharmacist or doctor for advice if you're not sure how to take it or have any problems taking it.
If you miss a dose of lisinopril
If you forget to take a dose of lisinopril, take it as soon as you remember, unless it's nearly time for your next dose.
If it’s nearly time for your next dose, skip the dose you missed and take your next dose at the usual time.
Do not take 2 doses to make up for a missed dose.
If you take too much lisinopril
Taking an extra dose of lisinopril can be dangerous.
Side effects of lisinopril
Like all medicines, lisinopril can cause side effects, although not everyone gets them.
Common side effects
Common side effects of lisinopril include:
- headaches
- feeling or being sick (nausea or vomiting)
- diarrhoea
- feeling dizzy, especially if you stand up quickly
- a dry cough that does not go away
- kidney problems (you'll have blood tests to check for this)
If you feel dizzy or drowsy after taking lisinopril, do not drive, ride a bike or use machinery until you no longer have these symptoms.
Who can and cannot take lisinopril
Lisinopril is a medicine for adults and children over 6 years old.
Lisinopril is not suitable for some people. For example, it may not be suitable if you’ve had an allergic reaction to lisinopril or another ACE inhibitor.
It also may not be suitable if you have:
- a condition called angioedema that causes swelling in areas such as your face, hands and feet, mouth or throat
- kidney problems
- liver problems
- treatment to prevent allergy symptoms, such as desensitisation therapy
Before taking lisinopril, tell your doctor if you have any medical conditions.
Breastfeeding and lisinopril
Tell your doctor if you're breastfeeding.
Lisinopril may be taken while breastfeeding, but it's best to check because the medicine may pass into your breast milk in small amounts.
A doctor may recommend you try a different ACE inhibitor, called enalapril, while you’re breastfeeding.
If you’re taking lisinopril while breastfeeding, speak to a healthcare professional or call NHS 111 if you have any concerns about your baby.
Pregnancy and lisinopril
Tell your doctor if you're pregnant or become pregnant.
Lisinopril is not usually used during pregnancy because it can:
- affect how your baby’s kidneys, skull, lungs and joints develop
- reduce the level of amniotic fluid that protects them in the womb
- increase the risk of stillbirth
A doctor will recommend an alternative medicine that’s safer to take during pregnancy.

There are some medicines, remedies and supplements that may not mix well with lisinopril.

- other medicines for high blood pressure and heart problems
