What Is Rosuvastatin and How Does It Work?
Rosuvastatin is used along with a proper diet to help lower "bad" cholesterol and fats (such as LDL, triglycerides) and raise "good" cholesterol (HDL) in the blood. It belongs to a group of drugs known as "statins." It works by reducing the amount of cholesterol made by the liver. Lowering "bad" cholesterol and triglycerides and raising "good" cholesterol decreases the risk of heart disease and helps to prevent strokes and heart attacks.
In addition to eating a proper diet (such as a low cholesterol/low-fat diet), other lifestyle changes that may help rosuvastatin work better include exercising, losing weight if overweight, and stopping smoking. Talk with your doctor for more details.
Rosuvastatin is available under the following different brand names: Crestor.

- Patients of Asian descent: Initiate with 5 mg/day
- Coadministration with other lipid-lowering therapy: Consider dose reduction if combined with niacin or fenofibrate, because of increased risk for skeletal muscle effects
- Coadministration with cyclosporine: Not to exceed 5 mg/day

- Treatment is supportive
- Severe (CrCl less than 30 mL/min/1.73m²) and not on hemodialysis: Decrease starting dose to 5 mg orally once/day; not to exceed 10 mg orally once/day
- CrCl greater than 30mL/min/1.73m²: Dose adjustment not necessary
- Active liver disease: Use is contraindicated
- Chronic alcoholic liver disease is known to increase rosuvastatin exposure; caution advised

Effects of Drug Abuse
- See "What Are Side Effects Associated with Using Rosuvastatin?"
- See "What Are Side Effects Associated with Using Rosuvastatin?"
- Non-serious and reversible cognitive side effects may occur.
- Increased blood sugar and glycosylated hemoglobin (HbA1c) levels reported with statin intake; in some instances these increases may exceed the threshold for the diagnosis of diabetes mellitus.
- Chronic liver disease.
- Measure liver enzymes before initiating and if signs or symptoms of liver injury occur.
- Consider lower initial dose (5 mg once/day) in patients with risk of myopathy.
- Increased risk of rhabdomyolysis, especially at highest approved dose of 40 mg/day; reserve highest dose only for patients who fail to achieve desired cholesterol level at 20 mg/day.
- Use 5 mg/day starting dose in people of Asian ancestry, who may build up higher drug levels and be at higher risk of myopathy.
- Rare reports of immune-mediated necrotizing myopathy (IMNM), characterized by increased serum creatine kinase that persists despite discontinuing statin.
- Discontinue if creatine kinase (CK) levels are markedly elevated.
Pregnancy and Lactation
- Rosuvastatin is contraindicated for use during pregnancy. Because HMG-CoA reductase inhibitors decrease cholesterol synthesis and possibly the synthesis of other biologically active substances derived from cholesterol (e.g., cell membranes), rosuvastatin may cause fetal harm when administered to pregnant women.
- Rosuvastatin is contraindicated for use while breastfeeding. Limited data indicate that rosuvastatin is present in human milk; because statins have the potential for serious adverse reactions in nursing infants, women who require rosuvastatin treatment should not breastfeed their infants.
