Rosuvastatin: 6 things you should know
Medically reviewed by C. Fookes, BPharm Last updated on Jan 28, 2019.
1. How it works
- Rosuvastatin works by blocking an enzyme, called HMG-CoA reductase, in the liver that makes different types of lipids (this is the collective term for fats and cholesterol). Rosuvastatin also boosts the breakdown of lipids.
- Rosuvastatin belongs to the class of medicines known as statins. Rosuvastatin is also known as an HMG-CoA reductase inhibitor.
- Rosuvastatin, in conjunction with dietary measures, is used to treat high lipid levels in people at increased risk of cardiovascular disease, if initial dietary measures fail to lower cholesterol.
- Used to treat primary hyperlipidemia or mixed dyslipidemia, hypertriglyceridemia, and some other lipid disorders.
- Also indicated in children aged 8 and older (heterozygous), or 7 or older (homozygous) with familial hypercholesterolemia (a genetic disorder resulting in high cholesterol) in addition to dietary measures and sometimes other lipid-lowering agents. Rosuvastatin is also used to slow the progression of atherosclerosis in adult patients.
- Rosuvastatin may be used for primary prevention of cardiovascular disease, to lower the risk of coronary events (such as heart attack, stroke, and angina) in patients at high risk of these events (for example those people with pre-existing coronary heart disease; diabetes; peripheral vessel disease; a previous history of stroke and stroke-like events or heart attack; or with multiple risk factors such as older age, smoking, high blood pressure, low HDL-C, or a family history of heart disease).
- Does not interact with grapefruit juice or products to the same extent as atorvastatin.
- Generic rosuvastatin is available.
If you are between the ages of 18 and 60, take no other medication or have no other medical conditions, side effects you are more likely to experience include:
- A headache, abdominal pain, weakness, a lack of energy, constipation, or nausea.
- Muscle aches and pain, tenderness, or weakness. Initially, this needs further investigating to rule out more serious muscle effects (such as rhabdomyolysis - the destruction of muscle cells). People aged older than 65, taking certain medications (for example cyclosporine, itraconazole, HIV antivirals), who drink more than two alcoholic drinks per day or with kidney disease appear more at risk of serious side effects.
- Cognitive effects (memory loss, forgetfulness, confusion) may occur with long-term use; however, these effects are usually reversible on discontinuation.
- Rosuvastatin, like other statins, may affect liver function, manifesting as changes in liver function tests or jaundice (yellowing of the skin) requiring dosage reduction or discontinuation.
- May also affect some diabetes markers (such as HbA1c or fasting glucose), and may not be suitable in those with liver or kidney disease. Transient dipstick-positive proteinuria and microscopic hematuria may also occur in rosuvastatin treated patients.
- May interact with other drugs including cyclosporine, gemfibrozil, warfarin, and protease inhibitors.
Notes: In general, seniors or children, people with certain medical conditions (such as liver or kidney problems, heart disease, diabetes, seizures) or people who take other medications are more at risk of developing a wider range of side effects.

- May be taken as a single dose daily, any time of the day, either with or without food.
- Do not take 2 doses of rosuvastatin within 12 hours of each other.
- Separate administration of rosuvastatin from antacids (give two hours apart).
- Consider temporarily withholding rosuvastatin and seeking urgent medical advice if you have any acute muscle pain or another condition that may increase your risk of serious muscle injury or kidney failure such as a severe infection, major surgery, trauma, uncontrolled seizures, severe electrolyte or metabolic disorders.
- Asian people may be particularly sensitive to rosuvastatin and require lower dosages.
- Dosage needs to be individualized but initially should start at 10-20 mg/day (Asian/pediatric patients: 5 mg/day) and be guided by the results of cholesterol tests taken 2 to 4 weeks later.
- Limit your alcohol intake and avoid drinking more than two glasses of alcohol per day while you are taking rosuvastatin.
- Seek urgent medical advice and consider temporarily withholding rosuvastatin if you develop any acute muscle pain or have another condition that may increase your risk of serious muscle injury or kidney failure such as a severe infection, major surgery, trauma, uncontrolled seizures, severe electrolyte or metabolic disorders.
- See your doctor straight away if you notice any yellowing of your skin or shortness of breath, unexplained cough or general tiredness.
- Adhere to the TLC diet, designed by the National Cholesterol Education Program (NCEP), or a similar diet, while taking rosuvastatin.
- Rosuvastatin should not be taken during pregnancy or while breastfeeding. Ensure you use effective contraception while taking rosuvastatin if you are a woman of childbearing age and talk to your doctor if you intend to become pregnant before you actually become pregnant.
6. Response and Effectiveness
- Peak levels or rosuvastatin are seen within three to five hours of oral administration. However, it may take one to two weeks of regular dosing before improvements in your cholesterol level are seen, and up to four weeks before the maximal cholesterol-lowering effects of rosuvastatin are apparent.
