Zocor vs. Pravachol
See how Zocor and Pravachol compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Zocor and Pravachol are both statins that lower LDL cholesterol, but they differ in dosing range, drug interactions, and pediatric approval age.
Zocor comes in four dose strengths from 10 mg to 80 mg, while Pravachol is typically dosed at 40 mg or 80 mg once daily.
Pravachol interacts with fewer medications than Zocor, which is contraindicated with strong CYP3A4 inhibitors.
Zocor vs. Pravachol Drug Summary
Zocor
Zocor (simvastatin) is a statin that lowers LDL cholesterol and triglycerides while raising HDL cholesterol. It is approved for adults with high cholesterol, certain inherited forms of high cholesterol, and for reducing heart attack and stroke risk in people with heart disease or diabetes. It comes as an oral tablet taken once daily at doses from 10 mg to 80 mg.
Pravachol
Pravachol (pravastatin) is a statin that lowers LDL cholesterol and triglycerides while raising HDL cholesterol. It is approved for adults with high cholesterol and for reducing heart attack and stroke risk, whether or not heart disease is already present, as well as for children with familial hypercholesterolemia. It comes as an oral tablet taken once daily, usually at 40 mg to 80 mg.

Zocor vs. Pravachol Indications
Zocor
Zocor is FDA-approved to lower LDL cholesterol in adults with high cholesterol and to treat certain inherited forms of high cholesterol, including in children 10 and older. It is also approved to reduce the risk of heart attack, stroke, and death in adults with heart disease or diabetes who face high cardiovascular risk.
Lowers LDL cholesterol in adults with primary hyperlipidemia
Treats heterozygous familial hypercholesterolemia in adults and kids 10+
Adjunct therapy for homozygous familial hypercholesterolemia
Reduces heart attack, stroke, and death risk in high-risk adults
Pravachol
Pravachol is FDA-approved to lower LDL cholesterol in adults with high cholesterol and to treat familial hypercholesterolemia in children as young as 8. It is also approved to reduce the risk of heart attack and stroke in adults with elevated cholesterol, whether or not they already have heart disease.
Lowers LDL cholesterol in adults with primary hyperlipidemia
Treats heterozygous familial hypercholesterolemia in kids 8+
Reduces heart attack and stroke risk in adults without heart disease
Slows plaque buildup and lowers risk in adults with known heart disease
Zocor vs. Pravachol Pros and Cons
Zocor
Zocor has a long history of use since 1991 and offers four dose strengths for flexible titration. As a widely available generic, it is typically covered by insurance formularies, though the 80 mg dose carries added muscle-injury risk and drug-interaction restrictions.
Pros
Four dose strengths (10-80 mg) allow fine-tuned titration
Decades of outcome data from long-term cardiovascular trials
Widely available as a low-cost generic
Cons
Contraindicated with strong CYP3A4 inhibitors, limiting drug combinations
Higher myopathy and rhabdomyolysis risk, especially at 80 mg
80 mg dose restricted to patients already tolerating it for 12+ months
Pravachol
Pravachol is processed differently by the liver than most statins, so it interacts with fewer medications. It is also approved for younger children, but its dosing options are more limited and its labeled rates of muscle and digestive side effects are higher.
Pros
Fewer interactions with drugs metabolized by liver CYP enzymes
Approved for children as young as 8 with familial hypercholesterolemia
Established outcome data for both primary and secondary prevention
Cons
Only two dose strengths (40 mg, 80 mg) versus Zocor's four
Higher labeled rates of musculoskeletal pain and GI side effects
Classified as a lower-to-moderate intensity statin
