Side Effects of Crestor

Crestor (rosuvastatin) is a prescription medication used to lower “bad” cholesterol (LDL) and triglycerides in the blood, while raising “good” cholesterol (HDL). It belongs to a class of drugs called statins, which help reduce the risk of heart attack, stroke, and other cardiovascular problems. Like all medications, Crestor can cause side effects. Understanding these can help you recognize warning signs early and know when to seek medical help.

Who Is at Higher Risk for Side Effects?

Certain factors can increase the likelihood of a side effect:

• Pre-existing liver or kidney problems
• Hypothyroidism (underactive thyroid)
• History of muscle disorders
• Multiple medications (especially other cholesterol-lowering drugs or certain antibiotics)

Tell your doctor about all your medical conditions, prescription drugs, over-the-counter medicines, and herbal supplements to minimize risks.

Balancing Benefit and Risk

For many people at risk of heart disease, the benefits of Crestor in lowering cholesterol and preventing cardiovascular events outweigh the potential side effects. However:

• Never stop Crestor abruptly without talking to your doctor.

Always seek medical advice if you experience:

• Unexplained muscle pain or dark urine
