What is Crestor (Rosuvastatin)?
Crestor (rosuvastatin) is a statin medication, otherwise known as an HMG-CoA reductase inhibitor, used to lower cholesterol levels and manage hereditary cholesterol disorders. It is prescribed alongside lifestyle modifications, including exercise and diet, to reduce their levels of low-density lipoprotein (LDL) cholesterol (“bad cholesterol”) and increase their levels of high-density lipoprotein (LDL cholesterol (“good cholesterol”).
How is Crestor Used?
This medication should be used alongside changes in a patient’s diet and exercise routine to reduce unhealthy cholesterol levels within the body. Most patients will take this medicine once per day and adjust the dose based on individual response and cholesterol levels, as determined by their doctor.
Storage
This medication should be stored at room temperature within the range of 68°F (20°C) to 77°F (25°C), and it should be kept away from direct heat or moisture.
Keep this medication out of the reach of children at all times.
Uses
Crestor is prescribed for a variety of conditions, including but not limited to:
- hyperlipidemia (high cholesterol levels)
- atherosclerosis
- heterozygous familial hypercholesterolemia
- homozygous familial hypercholesterolemia
- type III hyperlipoproteinemia (elevated beta-VLDL + intermediate-density lipoprotein, IDL)
- hypertriglyceridemia
- the reduction of heart attack and stroke risk
How Does Crestor Work?
This medication functions by inhibiting HMG-CoA reductase, an enzyme responsible for the production of cholesterol within the body. As a consequence, it reduces the unhealthy cholesterol levels within a patient’s body and lowers their risk of cardiovascular events. This medication works best alongside changes to a patient’s diet as well as exercise habits.

This medication is available in tablet form in the following strengths:
- 5 mg
- 10 mg

Warnings & Precautions
Alcohol Consumption
Consuming alcohol in excess or regularly while using this medication increases a patient’s risk of experiencing liver impairment and other hepatic issues. These patients may require additional monitoring during treatment to ensure proper liver function and safety while using Crestor.
Diabetes
This medication is capable of increasing a patient’s blood glucose levels and affecting their overall glucose tolerance. Patients with diabetes may need to monitor their blood glucose levels more closely during treatment with Crestor.
Those who are at risk of developing diabetes or who currently have the condition should be sure to discuss these aspects of their health history with their physician before beginning treatment with this medication, as this may impact the efficacy of the medication as well as dosage requirements.
Geriatric Patients
Senior patients above the age of 65 years will commonly require additional monitoring when using this medication to detect any muscle-related issues that may arise during treatment.
Hepatic Function
This medication is capable of impairing a patient’s liver function, and this may sometimes even result in liver failure. Patients who regularly consume alcohol are at a higher risk of experiencing hepatic impairment. Individuals using Crestor who experience any of the following liver-related symptoms should inform their physician as soon as possible: itchy skin, abdominal swelling, abdominal pain, pale-colored stools, dark-colored urine, jaundice, malaise, fatigue, or loss of appetite.
Those who have higher-than-normal liver function tests or who currently have active liver disease should not use this medication. Those with a history of hepatic impairment or other liver-related conditions should be sure to inform their prescribing physician of these aspects of their medical history before beginning treatment with this medication.
Hypersensitivity
Some patients will experience “hypersensitivity syndrome” when using a “-statin” medication like Crestor. These individuals will experience severe allergic reaction symptoms such as flu-like symptoms, swollen glands, blistering, skin rash, jaundice, or fever. Patients using this medication who experience any of these symptoms should seek out emergency medical attention as quickly as possible.
Muscle Damage
Some “-statin” medications have been linked to muscle damage, especially in patients who are taking higher doses of these medications. As a “statin,” Crestor also comes with this risk. Patients with the following may be more likely to experience muscle damage when using this medication: a family history of muscle-related disorders, the use of additional cholesterol-lowering medications, age above 70 years, being of Asian descent, have had any past muscle-related problems, have thyroid problems, have impaired hepatic or renal function, are taking additional medications for other conditions, have diabetes, consume three or more alcoholic beverages per day, have recently had a tissue injury, or have recently had any type of surgery.
Patients using this medication should report any unusual symptoms to their prescribing physician as soon as possible. This includes issues such as fever, dark-colored or brown urine, cramps, muscle pain, malaise, muscle weakness, or muscles that feel tender.
Renal Function
Individuals with kidney disease or impaired renal function should be sure to inform their doctor of these conditions before beginning treatment with this medication. In some cases, changes in the required dosage and any monitoring requirements may be necessary to ensure that Crestor is both safe and effective in these particular individuals.
Pediatric Patients
This medication may be used in patients ranging from 10 years to 17 years of age who have been diagnosed with certain cholesterol-related disorders that are hereditary. However, any children in this age range who are capable of menstruation should have at least been menstruating for one full year before using Crestor.
It has not been determined if this medication is safe or effective in patients below the age of 10.
Any pediatric patient using Crestor should be closely monitored for the duration of their treatment with this medication.
Pregnancy and Breastfeeding
This medication is not safe for use by pregnant individuals, and any patients using this medication who become pregnant during treatment should inform their prescribing physician immediately.
Additionally, it has not been determined if this medication is safe for use by patients who are breastfeeding. This medication may pass into breast milk and affect a breastfed child. Patients desiring to breastfeed while using Crestor should discuss the possible risks with their physician before continuing to do so.
