About ezetimibe

Ezetimibe is a type of medicine used to lower cholesterol.

It's used to treat high blood cholesterol. This is when you have too much of a fatty substance called cholesterol in your blood.

You may also be prescribed ezetimibe if you cannot take cholesterol-lowering medicines called statins, or if statins do not work for you.

Ezetimibe is available on prescription only. It comes as tablets.

Ezetimibe also comes mixed with simvastatin, a type of statin. This is known by the brand name Inegy.

How and when to take it

You can take ezetimibe with or without food.

The dose for adults and children is one 10mg tablet, taken once a day.

If you forget to take ezetimibe, take it as soon as you remember. If you do not remember until the following day, skip the missed dose and take your next one at the usual time.

Do not take a double dose to make up for a forgotten dose. If you often forget doses, it may help to set an alarm to remind you.

You could also ask a pharmacist for advice on other ways to help you remember to take your medicine.

What if I take too much?

Taking 1 or 2 extra tablets is unlikely to harm you. But the amount of ezetimibe that can lead to overdose is different from person to person.

You take too much ezetimibe and you:

Go to or call 111

Keep taking the medicine, but talk to a doctor if these side effects bother you or do not go away:

  • stomach (abdominal) pain
  • diarrhoea
  • farting more than usual

Tell a doctor straight away if you get:

  • muscle pain, tenderness, weakness or cramps
  • yellow skin or the whites of your eyes turn yellow, pale poo and dark pee – this can be a sign of liver problems
  • severe stomach pain (just under your ribs) – this can be a symptom of pancreas problems

Serious allergic reaction

In rare cases, it's possible to have a serious allergic reaction (anaphylaxis) to ezetimibe.

Call 999 or go to A&E if:

  • you get a skin rash that may include itchy, red, swollen, blistered or peeling skin

How to cope with side effects

What to do about:

  • stomach (abdominal) pain – try to rest and relax. It can help to eat and drink slowly and have smaller and more frequent meals. Putting a heat pad or covered hot water bottle on your stomach may also help. If you're in a lot of pain, speak to a pharmacist or doctor.
  • diarrhoea – drink lots of fluids, such as water or squash, to avoid dehydration. Speak to a pharmacist if you have signs of dehydration such as peeing less than usual or having dark, strong-smelling pee. Do not take any other medicines to treat diarrhoea without speaking to a pharmacist or doctor. Speak to a doctor if diarrhoea lasts for more than a week after you start ezetimibe.
  • farting – try to not eat foods that cause wind (such as lentils, peas, beans and onions). Eat smaller meals, eat and drink slowly, and exercise regularly. There are pharmacy medicines that may also help, such as charcoal tablets or simeticone. Peppermint tea may also help.
  • feeling tired – try to relax when possible and avoid intense exercise to see if that helps. If these symptoms do not go away after 1 to 2 weeks, ask a pharmacist or doctor for advice.

Pregnancy and breastfeeding

Ezetimibe is not usually recommended during pregnancy or while breastfeeding. This is because there is very little information about its safety.

A doctor may suggest another medicine for lowering cholesterol, such as colestyramine.

Speak to a doctor if you're:

  • trying to get pregnant
  • pregnant
  • breastfeeding

Cautions with other medicines

Some medicines can affect the way ezetimibe tablets work. They may also make your more likely to get side effects.

Tell a doctor if you're taking these medicines before you start ezetimibe:

  • ciclosporin, a medicine used to treat psoriasis or after an organ transplant
  • medicines used to prevent blood clots, such as warfarin
  • other medicines used for lowering cholesterol (this does not include statins), such as colestyramine or bezafibrate

There's very little information about taking herbal medicines and supplements with ezetimibe.
