Rosuvastatin - Common brands: Crestor

Rosuvastatin is a medicine used to treat high cholesterol and prevent heart attacks and strokes. You can only get it with a prescription.

What rosuvastatin is for

Rosuvastatin is used to treat high cholesterol. Having high cholesterol can cause problems with your heart and blood vessels (cardiovascular disease).

It's a type of cholesterol-lowering medicine called a statin.

Rosuvastatin can help:

  • bring your cholesterol levels down if you have high cholesterol
  • prevent angina, heart attack, stroke and other complications if you have cardiovascular disease

You may also be prescribed rosuvastatin if you have familial hypercholesterolaemia (a condition that can cause high cholesterol).

How to take rosuvastatin

Rosuvastatin usually comes as tablets or capsules. Some tablets melt in your mouth (orodispersible).

How much you need to take depends on why you're taking it. Your doctor may prescribe a low dose to start with and then increase it, if needed, after 4 weeks.

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.

When taking rosuvastatin:

  • swallow tablets or capsules whole with a drink of water, or if you have orodispersible tablets let them melt on your tongue before swallowing – you can swallow them with or without water
  • take it once a day – try to take it at the same time each day
  • you can take it with or without food

You usually need to take rosuvastatin for a long time, sometimes for life.

Important

Keep taking this medicine, unless your doctor tells you to stop. If you stop taking rosuvastatin, your cholesterol levels may go up again.

If you miss a dose of rosuvastatin

If you forget to take a dose of rosuvastatin, 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 rosuvastatin

Taking an extra dose of rosuvastatin is unlikely to cause problems, but it's important to get medical advice if you take too much as it can sometimes be dangerous.

Urgent advice: Speak to a pharmacist as soon as possible if:

  • you've taken more than your prescribed dose of rosuvastatin

If you’re unable to speak to a pharmacist, or you took too much of your medicine on purpose, call NHS 111 for advice.
