What is the standard Lipitor dosage?
Lipitor (atorvastatin) treats high cholesterol and prevents cardiovascular events. Doctors typically start adults at 10-20 mg once daily, adjusting up to 80 mg based on LDL goals, response, and tolerance. Take it anytime, with or without food.[1]
How much Lipitor for high cholesterol?
For primary prevention in patients without heart disease, 10-20 mg daily lowers LDL by 35-50%. In those with coronary heart disease or diabetes, 10-40 mg targets LDL under 100 mg/dL. Max is 80 mg for severe cases unresponsive to lower doses.[1][2]
Lipitor dosing by patient age or condition
- Children (10+ years, familial hypercholesterolemia): 10-20 mg daily; max 20 mg in girls, 40 mg in boys post-puberty.
- Elderly (70+): Start at 10 mg; same max as adults.
- Kidney/liver issues: Reduce to 10-20 mg; avoid in active liver disease.
Evidence from trials like TNT shows 80 mg cuts major events by 22% vs. 10 mg in high-risk patients.[2]
What if I miss a dose or need to adjust?
Skip missed dose; don't double up. Adjustments happen every 2-4 weeks via blood tests. Statins like Lipitor interact with grapefruit (raises levels 15%), fibrates, or cyclosporine—dose cut needed.[1]
Lipitor vs. other statins: Dose comparisons
| Statin | Equivalent to Lipitor 20 mg | Max Daily Dose |
|--------|-----------------------------|----------------|
| Crestor (rosuvastatin) | 5-10 mg | 40 mg |
| Zocor (simvastatin) | 40 mg | 40 mg |
| Pravachol (pravastatin) | 40 mg | 80 mg |
Lipitor's potency lets lower doses match rivals' effects.[3]
When does Lipitor's patent expire, and what about generics?
Original patents expired in 2011; generics (e.g., atorvastatin from Teva, Mylan) match brand dosing exactly and cost 80-90% less. Check DrugPatentWatch.com for formulation-specific expirations.[4]
