How can you reduce your risk?
Take atorvastatin as prescribed, tell your pharmacist about other medicines you use, and attend recommended checkups. Do not stop the medication or change your dose without medical advice.
Important: These symptoms can have causes other than atorvastatin. The medicine’s protection against heart attacks and strokes is important, so suspected side effects should be assessed rather than ignored or automatically blamed on the drug.
