Lipitor dosage for what conditions?

Lipitor dosage for cholesterol conditions

Lipitor is approved for adults with high LDL cholesterol, mixed high cholesterol and triglycerides, or isolated high triglycerides. Doctors also prescribe it for patients with coronary heart disease or diabetes who need LDL reduction to lower heart-attack risk. The usual starting dose is 10 mg or 20 mg once daily, taken any time of day. People who need greater LDL lowering begin at 40 mg. The maximum approved dose is 80 mg daily, used only when lower doses do not reach target levels.

Lipitor dosage for children and adolescents

For children 10–17 years old with heterozygous familial hypercholesterolemia, the starting dose is 10 mg once daily. The dose may be increased to 20 mg after four weeks if LDL goals are not met. Doses above 20 mg have not been studied in this age group.

How Lipitor dosage changes with kidney or liver issues

No dose adjustment is needed for mild to moderate kidney impairment. Severe kidney disease requires careful monitoring but not an automatic reduction. Active liver disease or unexplained persistent liver-enzyme elevations are contraindications; therapy should be stopped if significant liver injury develops.

What happens if you miss or double a Lipitor dose

Take the missed dose as soon as remembered unless it is nearly time for the next dose; skip the missed tablet and resume the regular schedule. Never double the next dose to compensate.

Lipitor dosage compared with other statins

Atorvastatin 10–20 mg produces LDL reductions similar to simvastatin 20–40 mg or rosuvastatin 5–10 mg. The 80 mg atorvastatin dose lowers LDL roughly 50 percent, comparable to the highest approved doses of rosuvastatin. Choice among statins often depends on cost, drug-interaction potential, and individual response.

When does the Lipitor patent expire and what about generics

The key U.S. patent for atorvastatin expired in 2011, allowing generic versions to enter the market. Multiple manufacturers now supply generic atorvastatin at substantially lower cost than brand-name Lipitor. [1]
