Crestor® is a medication that helps lower cholesterol. This drug is also known by its generic name: rosuvastatin. It is available by prescription only. Crestor® is commonly prescribed to adults; however, it may also be used for children with high cholesterol who are at least ten years old.

Some cholesterol medications may provide only one main health benefit: to lower levels of low-density lipoprotein (LDL), also known as bad cholesterol. Crestor® acts by blocking the production of cholesterol in order to lower LDL levels. In addition, it works to increase levels of high-density lipoprotein (HDL), also known as good cholesterol. Healthy cholesterol levels can help prevent certain medical conditions, such as a stroke or a heart attack.

Patients should follow dosing instructions carefully. This drug may be taken with or without a meal; however, it should be taken with a full glass of water. This medication should also be taken at the same time each day. Patients of Asian descent may need to take a lower dosage initially because the drug may absorb more quickly.

Crestor® may be less effective in lowering cholesterol if the patient does not faithfully follow a low-cholesterol diet. Patients should also avoid drinking alcohol while taking this medication, as this could result in liver damage. Antacids may block the absorption of this medication, especially if used within two hours after taking the drug.

The United States (US) Food and Drug Administration (FDA) has categorized Crestor® in the pregnancy category X. This means that this medication may cause birth defects. Patients should never use this drug while pregnant or breastfeeding. A doctor may instruct his or her patient to use an effective birth control method while taking this medication.

All medications carry the risk of some side effects. Not all patients experience them; however, some possible side effects include dizziness, nausea, and diarrhea. People taking Crestor® may also experience constipation, headaches, or memory loss.

Patients who experience more serious side effects should seek medical help immediately. These serious side effects may include flu symptoms, muscle pain, and dark-colored urine. Possible signs of an allergic reaction may include facial swelling, hives, and problems breathing properly.

This medication may also interact with other drugs. Patients who are on any other prescription medications or over-the-counter supplements should discuss these with their doctor. Some drugs that Crestor® may interact with include blood-thinners, cyclosporine, and other cholesterol-lowering medications.

High LDL cholesterol is a medical problem that can be addressed through three primary avenues: medication, diet, and exercise. While Crestor® can help lower cholesterol, patients will also likely need to address their health issues through diet and exercise. Doctors and dietitians can help patients develop a strategic diet and exercise plan.
