Standard Starting Dose for Adults
The minimum daily dose of Lipitor (atorvastatin) for adults is 10 mg once daily, typically taken in the evening regardless of food.[1][2]
When Is 10 mg Used?
Doctors prescribe 10 mg as the starting dose for most adults with high cholesterol, cardiovascular risk reduction, or primary prevention of heart disease. It's effective for many patients and allows monitoring for response and side effects before increasing.[1][3]
Dose Adjustments and Maximum
Dose can increase to 20 mg, 40 mg, or up to 80 mg daily based on LDL cholesterol goals, response, and tolerability. Adjustments occur every 2-4 weeks. Use lower doses (starting at 10 mg) in patients with kidney issues, low body weight, or on certain interacting drugs like cyclosporine.[1][2]
Special Populations
- Elderly (≥65 years): Start at 10 mg due to higher risk of muscle issues.[1]
- Kidney or liver impairment: Minimum 10 mg; avoid in active liver disease.[2]
- Asian patients: Start at 10 mg (or 5 mg off-label) due to higher drug exposure.[1][3]
Common Side Effects at Low Doses
Muscle pain, nausea, or diarrhea occur in <5% of patients on 10 mg. Rare risks include rhabdomyolysis; report unexplained muscle weakness.[1][4]
