Lipitor vs. Zocor
See how Lipitor and Zocor compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Lipitor and Zocor are both statins that lower LDL cholesterol and triglycerides, but they differ in which patients they are approved to treat and in price.
Lipitor is approved for primary prevention of heart attack and stroke in adults with multiple cardiovascular risk factors, while Zocor's risk-reduction use is limited to those with existing heart disease or diabetes.
Zocor's highest 80 mg dose carries extra restrictions due to muscle injury risk, while Lipitor has no boxed warning and no similar dose-duration requirement.
Lipitor vs. Zocor Drug Summary
Lipitor
Lipitor (atorvastatin) is an HMG-CoA reductase inhibitor, or statin, used to lower LDL cholesterol and triglycerides and to reduce cardiovascular risk. It is taken as an oral tablet once daily, with doses ranging from 10 mg to 80 mg depending on how much LDL lowering is needed.
Zocor
Zocor (simvastatin) is also an HMG-CoA reductase inhibitor used to lower LDL cholesterol and reduce cardiovascular risk in certain high-risk patients. It is taken as an oral tablet once daily, with doses from 10 mg to 80 mg, though the highest dose has added restrictions.

Lipitor vs. Zocor Indications
Lipitor
Lipitor is FDA-approved for lowering LDL cholesterol and triglycerides in adults and children 10 and older with dyslipidemia. It also reduces the risk of heart attack, stroke, and certain heart surgeries in adults with multiple cardiovascular risk factors, and it treats both heterozygous and homozygous familial hypercholesterolemia.
Lowering LDL cholesterol and triglycerides in adults and children 10+
Reducing heart attack, stroke, and heart surgery risk with multiple CV risk factors
Reducing heart attack and stroke risk in adults with type 2 diabetes
Treating heterozygous familial hypercholesterolemia in adolescents
Zocor
Zocor is FDA-approved for lowering LDL cholesterol in adults with primary hyperlipidemia and for treating familial hypercholesterolemia in appropriate patients. It also reduces the risk of heart attack, stroke, and death in adults with existing heart disease or diabetes who are at high cardiovascular risk.
Lowering LDL cholesterol in adults with primary hyperlipidemia
Treating heterozygous familial hypercholesterolemia in adults and children 10+
Adjunct therapy for homozygous familial hypercholesterolemia
Reducing heart attack, stroke, and death risk in high-risk heart disease or diabetes
Lipitor vs. Zocor Pros and Cons
Lipitor
Lipitor is a widely prescribed statin with FDA approval for primary prevention of heart attack and stroke, not just for people who already have heart disease. It carries no boxed warning and does not require a tolerance period before reaching its highest dose, though its list price runs higher than generic simvastatin.
Pros
No boxed warning, unlike some other lipid-lowering therapies
Approved for primary prevention in adults with multiple cardiovascular risk factors, even without diagnosed heart disease
No 12-month tolerance requirement before reaching the highest 80 mg dose
Cons
Costs roughly $450 to $530 per month without insurance, notably more than simvastatin
Not approved for Fredrickson Type I or Type V dyslipidemias
Trial data show arthralgia (up to 6.9%) and diarrhea (up to 6.8%) as common side effects
Zocor
Zocor was one of the first statins on the market and has decades of clinical experience behind it. Its highest 80 mg dose carries added restrictions due to muscle injury risk, and it interacts with a narrower range of medications because of CYP3A4 contraindications, but it remains one of the most affordable statin options available.
Pros
Roughly $75 to $100 per month without insurance, much less than Lipitor's $450 to $530
Decades of real-world use since its approval in 1991, one of the first statins available
FDA-approved specifically to reduce heart attack, stroke, and death risk in adults with existing heart disease or diabetes
Cons
80 mg dose restricted to patients who have already tolerated it for 12+ months due to muscle injury risk
Contraindicated with strong CYP3A4 inhibitors, limiting which other medications can be combined
Not approved for use in children under age 10
