Lipitor vs. Zetia
See how Lipitor and Zetia compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Lipitor and Zetia both lower LDL cholesterol but work differently: Lipitor blocks cholesterol production in the liver, while Zetia blocks its absorption in the gut.
Lipitor has decades of outcomes data and is approved to cut heart attack and stroke risk, while Zetia is typically added on when a statin alone isn't enough.
Both drugs are available as low-cost generics, so price is unlikely to be the deciding factor between them.
Lipitor vs. Zetia Drug Summary
Lipitor
Lipitor (atorvastatin) is a statin that blocks an enzyme the liver uses to make cholesterol, lowering LDL and triglycerides. It's taken as a once-daily tablet at doses from 10 mg to 80 mg, and is also approved to reduce the risk of heart attack and stroke in people with cardiovascular risk factors.
Zetia
Zetia (ezetimibe) works differently: it blocks cholesterol absorption in the small intestine rather than acting on the liver. It's taken as a single 10 mg tablet once daily, either on its own or added to a statin for extra LDL lowering.

Lipitor vs. Zetia Indications
Lipitor
Lipitor is FDA-approved to lower LDL cholesterol and triglycerides in adults and children 10 and older with dyslipidemia. It's also approved to reduce the risk of heart attack, stroke, and certain heart procedures in adults with cardiovascular risk factors or type 2 diabetes, and to treat familial hypercholesterolemia.
Lowering LDL cholesterol and triglycerides in adults and kids 10+
Reducing heart attack, stroke, and heart surgery risk with CV risk factors
Reducing heart attack and stroke risk in type 2 diabetes
Treating heterozygous familial hypercholesterolemia in teens
Zetia
Zetia is FDA-approved to lower LDL cholesterol in adults with primary hyperlipidemia, either alone or combined with a statin. It's also approved for mixed hyperlipidemia with fenofibrate, and for familial hypercholesterolemia in combination with a statin in patients 10 and older.
Lowering LDL alone or with a statin in primary hyperlipidemia
Lowering LDL in kids 10+ with heterozygous FH, plus a statin
Lowering LDL in mixed hyperlipidemia, combined with fenofibrate
Lowering LDL in homozygous FH, combined with a statin
Lipitor vs. Zetia Pros and Cons
Lipitor
Lipitor has the longest track record of any statin and is backed by large outcomes trials showing reduced heart attack and stroke risk. It's widely covered by insurance and available as a low-cost generic, though it does carry a real risk of muscle-related side effects.
Pros
Approved to reduce heart attack and stroke risk, not just lower LDL
Also lowers triglycerides in addition to LDL cholesterol
Decades of real-world safety data since 1996
Generic version available since 2011
Cons
Carries risk of muscle pain and, rarely, rhabdomyolysis
Can raise liver enzymes, requiring monitoring
Contraindicated during pregnancy and breastfeeding
Zetia
Zetia takes a different approach, blocking cholesterol absorption in the intestine instead of acting on the liver. It's often added to a statin for extra LDL lowering, or used alone in people who can't tolerate statins, though its effect by itself is more modest.
Pros
Works through a different mechanism, blocking absorption in the gut
Milder overall side effect profile when used alone
Option for patients who can't tolerate statin muscle symptoms
Only one tablet strength and dose to keep track of
Cons
Not approved as the sole treatment for homozygous FH
Provides more modest LDL reduction alone than a statin
Still carries some muscle-related risk when combined with a statin
