If you have any questions about CRESTOR, ask your doctor. Only your doctor can determine if CRESTOR is right for you.

What is CRESTOR?

CRESTOR is a prescription medicine that contains a cholesterol-lowering medicine called rosuvastatin calcium. CRESTOR is used along with diet to:

  • lower the level of your “bad” cholesterol (LDL)
  • increase the level of your “good” cholesterol (HDL)
  • lower the level of fat in your blood (triglycerides)
  • slow the buildup of fatty deposits (plaque) in the walls of blood vessels

CRESTOR is for patients who cannot control their cholesterol levels by diet and exercise alone.

CRESTOR is used to reduce the risk of heart attacks and strokes in men 50 years of age and older and women 60 years of age and older who do not have known heart disease but do have certain additional risk factors.

It is not known if CRESTOR is safe and effective in people who have Fredrickson Type I and V dyslipidemias.

General Information about the safe and effective use of CRESTOR

Most of the cholesterol in your blood is made in the liver. CRESTOR works by reducing cholesterol in two ways: CRESTOR blocks an enzyme in the liver causing the liver to make less cholesterol, and CRESTOR increases the uptake and breakdown by the liver of cholesterol already in the blood.

Medicines are sometimes prescribed for purposes other than those listed in a Patient Information leaflet. Do not use CRESTOR for a condition for which it was not prescribed. Do not give CRESTOR to other people, even if they have the same medical condition you have. It may harm them.

This Patient Information summarizes the most important information about CRESTOR. If you would like more information, talk to your doctor. You can ask your pharmacist or doctor for information about CRESTOR that is written for health professionals.
