What Is Crestor?
Crestor (rosuvastatin) is a prescription lipid-lowering medication. Lipids are fats in the body, and elevated lipid levels increase the risk of blood clots that cause heart attacks and strokes. This medication is available in tablet form to be taken by mouth.
Crestor is considered a statin. It lowers lipids by reducing the formation and increasing the breakdown of certain lipid molecules. Crestor inhibits HMG-CoA reductase, an enzyme involved in the production of cholesterol.

What Is Crestor Used For?
The Food and Drug Administration (FDA) approved Crestor to treat several different conditions that are characterized by high fat and cholesterol levels. This may include high measures of low-density lipoprotein (LDL, considered "bad"), triglycerides (TG), total cholesterol, apolipoprotein B-100 (ApoB, a protein on the fat particles), and low measures of high-density lipoprotein (HDL, considered "good") cholesterol.
Crestor treats hyperlipidemia (high levels of fat and cholesterol) that occurs due to certain diseases as well as due to primary hyperlipidemia (without another known cause). It is approved for use for children as young as 7 years old for some conditions. Often, dietary modifications are recommended along with Crestor to help balance fat and cholesterol levels.
Crestor is approved for:
- Adults with primary hyperlipidemia and mixed dyslipidemia in addition to diet to reduce elevated total cholesterol, LDL, ApoB, non-HDL cholesterol, and TG levels, and to increase HDL.
- Children age 8 to 17 with heterozygous familial hypercholesterolemia to reduce elevated total cholesterol, LDL, and ApoB if diet therapy is not effective.
- Children age 7 to 17 with homozygous familial hypercholesterolemia to reduce LDL, total cholesterol, non-HDL cholesterol, and ApoB as an add-on (adjunct) therapy to diet, either alone or with other lipid-lowering treatments.
- Adults with hypertriglyceridemia as an adjunct to diet
- Adults with primary dysbetalipoproteinemia as an adjunct to diet
- Adults with homozygous familial hypercholesterolemia to reduce LDL, total cholesterol, and ApoB
- Slowing the progression of atherosclerosis as part of a treatment strategy to lower total cholesterol and LDL as an adjunct to diet
- Risk reduction of myocardial infarction (heart attack), stroke, and arterial revascularization procedures in people without clinically evident coronary heart disease, but with multiple risk factors
Crestor is used long-term to gradually reach target lipid levels and reduce the risks associated with having high lipids and low HDL.
How to Take Crestor
Your healthcare provider would prescribe Crestor for once-a-day dosing to take any time of the day, with or without food. You should swallow the tablet whole.
Storage
Store Crestor in its original container and away from the reach of children or pets. Keep it in a dry place at a room temperature between 68 degrees to 77 degrees Fahrenheit. Do not store it in the bathroom or other areas containing moisture.
Off-Label Uses
Healthcare providers sometimes prescribe medications for off-label use, meaning for conditions that it is not FDA approved for but has shown benefit in treating.
Crestor has a few off-label uses. Crestor has been prescribed off-label for children younger than age 7 diagnosed with familial hypercholesterolemia.
Other off label uses of Crestor include:
- Treatment after a stroke
- Before percutaneous coronary intervention for an acute cardiac (heart) event
Crestor has been shown to reduce brain or heart damage when used in these situations.
What Are the Side Effects of Crestor?
The common side effects of Crestor are bothersome, but not dangerous. This medication can also cause serious side effects.
This is not a complete list of side effects and others may occur. A healthcare provider can advise you on side effects. If you experience other effects, contact your pharmacist or a healthcare provider. You may report side effects to the FDA at fda.gov/medwatch or 1-800-FDA-1088.
Common Side Effects
The most common side effects of Crestor are:
- Headaches
- Muscle aches and pains
- Abdominal pain
- Generalized weakness
- Nausea
Tell your healthcare provider if you experience these side effects. Another problem, not Crestor, could be causing these symptoms. Treatment for the underlying cause would then be required. If these symptoms result from taking Crestor, your provider may suggest or prescribe a treatment to help alleviate them.
Severe Side Effects
Crestor can cause serious side effects that can be harmful to your health.
Severe side effects of Crestor are:
- Muscle problems: Myopathy (muscle disease) and rhabdomyolysis (muscle breakdown) can cause muscle pain, tenderness, or weakness, and can be serious when accompanied by a fever.
- Liver damage: This can cause abnormalities in liver enzymes, feeling extremely tired or weak, upper-abdominal pain, loss of appetite, dark urine, and jaundice (yellowish discoloration of the skin or eyes).
Your healthcare provider may monitor you for changes in your liver enzymes while taking Crestor. Notify your provider if you experience signs of muscle or liver damage. Let your doctor know if your muscle pains continue after you are asked to stop Crestor. Further testing may be needed.
Long-Term Side Effects
Liver damage can be long-lasting, potentially causing health problems after you stop taking Crestor. Rhabdomyolysis can cause kidney damage, and it may take a long time for the muscles to recover.
Report Side Effects
Crestor may cause other side effects. Call your healthcare provider if you have any unusual problems while taking this medication.
If you experience a serious side effect, you or your provider may send a report to the FDA's MedWatch Adverse Event Reporting Program or by phone (800-332-1088).

It is very important that your doctor check your progress at regular visits. This will allow your doctor to see if the medicine is working properly to lower your cholesterol and triglyceride levels and to decide if you should continue to take it. Blood and urine tests may be needed to check for unwanted effects.
Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant. If you think you have become pregnant while using the medicine, tell your doctor right away.
Make sure any doctor or dentist who treats you knows that you are using this medicine. You may need to stop using this medicine if you have a major surgery, major injury, or if you develop other serious health problems.
Call your doctor right away if you have unexplained muscle pain, tenderness, or weakness, especially if you also have unusual tiredness or a fever. These may be symptoms of serious muscle problems, such as myopathy or immune-mediated necrotizing myopathy (IMNM).
Call your doctor right away if you have dark urine, fever, muscle cramps or spasms, muscle pain or stiffness, or unusual tiredness or weakness. These could be symptoms of a serious muscle problem called rhabdomyolysis, which can cause kidney problems.
Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.
Do not stop or change your dose without checking first with your doctor, even if you are feeling well.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
