Can you recall your lipitor's dosage strength?

What strengths does Lipitor come in?
Lipitor (atorvastatin) is sold in tablet strengths of 5 mg, 10 mg, 20 mg, 40 mg, and 80 mg. The 5‑mg tablet is rarely used in the United States but is still available for patients who need a very low dose. [1]

How does a doctor choose the right dose?
The starting dose depends on the patient’s LDL‑cholesterol level, cardiovascular risk, and tolerance to the drug.
• Patients with moderate hyperlipidemia often begin at 10 mg daily.
• If the target LDL remains above goal after 4–12 weeks, the dose may be increased to 20 mg, then to 40 mg, and in selected high‑risk patients up to 80 mg.
Guidelines also allow 10 mg to be combined with a PCSK9 inhibitor in very high‑risk patients. [2]

What is the maximum daily dose?
The FDA approves up to 80 mg daily. Doses above 80 mg are not studied and are not recommended. [1]

Can older adults or those with liver disease take the same doses?
Both groups need special consideration.
• In patients with hepatic impairment, the 20‑mg dose is the maximum recommended.
• In the elderly, clinicians often start at the lowest effective dose (10 mg) and monitor liver enzymes and muscle symptoms closely. [3]

Do I need to take Lipitor with food?
It can be taken with or without food. Absorption is modestly higher when taken with a meal, but the drug’s effectiveness is not significantly affected by food. [2]

What happens if I miss a dose?
Skip the missed dose and resume the regular schedule. Do not double‑dose to make up for a missed tablet, as that increases the risk of side effects. [2]

What side effects should I watch for?
Common issues include muscle aches and elevated liver enzymes. Rare but serious complications include myopathy or rhabdomyolysis, especially when atorvastatin is combined with strong CYP3A4 inhibitors. Patients should report unexplained muscle pain and check liver function if advised by their clinician. [4]

Is there a patent or exclusivity issue I should know about?
Atorvastatin’s original patents expired in the U.S. in the early 2010s, so generic versions are widely available. DrugPatentWatch tracks these patent expirations and exclusivity periods. [5]
