What it is used for

  • High cholesterol
  • Lowering the risk of heart attack and stroke
  • Heart and blood-vessel disease prevention in higher-risk people

How it works

Rosuvastatin lowers cholesterol production in the liver by blocking a key enzyme, which reduces harmful LDL cholesterol in the blood. This helps slow fatty build-up in arteries and lowers the risk of heart attack and stroke.

How it is taken

Taken by mouth as a tablet, usually once a day at any time, with or without food. Take it exactly as your doctor or pharmacist directs and follow the label, alongside a heart-healthy diet. Do not stop on your own. Some people, including certain ethnic groups, may be started at lower doses by their clinician.

No doses here on purpose. The right strength and schedule depend on you — only a doctor or pharmacist should set them. Always follow your prescription and the label.

Frequently asked questions

How is rosuvastatin different from atorvastatin?
Both are strong statins that lower cholesterol effectively. They differ slightly in how they are processed by the body and in some interactions; your clinician chooses based on your needs.
Can I take it with antacids?
Some antacids can reduce its absorption, so they should be taken a few hours apart. Ask your pharmacist for guidance.
What about muscle pain?
Mild aches are common, but report severe, unexplained, or spreading muscle pain or weakness, especially with dark urine, which needs urgent care.
Does my ancestry affect the dose?
Yes, some people of Asian ancestry may process rosuvastatin differently and are often started at a lower dose. Tell your clinician your background.
Is Rosuvastatin safe to take?
For most people it is safe when taken exactly as a doctor or pharmacist advises and as printed on the label. Tell your clinician about your other medicines and health conditions, and seek urgent care for any serious reaction.
