Atorvastatin, by Pfizer.

Atorvastatin (Lipitor) Information

Lipitor is the brand name. Atorvastatin is the generic name. Atorvastatin is a highly effective statin (cholesterol-lowering drug) that lowers LDL cholesterol and triglyceride levels. Atorvastatin has also been shown to reduce the risk of heart attack or angina (chest pain) in people with coronary heart disease risk factors, such as hypertension, being age 55 years or older, smoking, low HDL cholesterol ("good" cholesterol) levels, or family history of early coronary heart disease.

Why Is Lipitor Used?

Lipitor is a prescription medication that lowers the levels of "bad" cholesterol and triglycerides and raises the levels of "good" cholesterol in the blood. LDL, or low-density lipoprotein, is referred to as the "bad" cholesterol. HDL, or high-density lipoprotein, is known as the "good" cholesterol. Lipitor is indicated for both adults and children older than 10 years whose cholesterol is not reduced enough with exercise and a low-fat diet

Use of Lipitor in children is specifically indicated for an inherited condition, known as heterozygous familial hypercholesterolemia, that causes high cholesterol at a young age. Lipitor is indicated for children aged 10-17 years with heterozygous familial hypercholesterolemia (girls in this age range must have already begun menstruating). When used along with diet, statins reduce total cholesterol, LDL, and apo B levels in children with heterozygous familial hypercholesterolemia. After an adequate trial of diet therapy, statins may be considered for treatment in children if one of the following findings is present:

• LDL-C remains greater than or equal to 190 mg/dL.
• LDL-C remains greater than or equal to 160 mg/dL and one of the following exists:
  • A positive family history of premature cardiovascular disease
  • Two or more other cardiovascular disease risk factors in the pediatric patient

Who Should Not Take Lipitor?

You should not take Lipitor if you fit any of the following situations:

• You are pregnant, think you may be pregnant, or are planning to become pregnant. Lipitor may harm your unborn baby. If you become pregnant, stop taking Lipitor and call your doctor right away.
• You are breastfeeding. Lipitor can pass into your breast milk and may harm your baby.
• You have liver problems.
• You are allergic to Lipitor or any of its ingredients.

Special Warnings With Lipitor

Lipitor may cause serious, but rare, side effects, including the following:

• Muscle breakdown (myopathy): Muscle breakdown symptoms include widespread muscle aches, muscle tenderness, and generalized weakness. Rarely, widespread muscle breakdown, known as rhabdomyolysis, can occur, usually in people who are taking other drugs that interfere with the body's ability to metabolize the statin and in people with advanced kidney problems. Therefore, it is extremely important that you inform your doctor about all the medications, herbal preparations, and dietary supplements you are currently taking. If you experience diffuse muscle pain and weakness, or if your urine is brown (a possible sign of muscle breakdown), contact your doctor immediately and stop taking the statin medication.
• Liver problems: Lipitor can cause liver problems. Your doctor may do a blood test to check your liver before you start taking Lipitor and while you are taking it.

What Should I Tell My Doctor?

Before starting Lipitor, tell your doctor about all of your medical conditions, including the following:

• If you have muscle aches or weakness
• If you drink more than 2 glasses of alcohol daily
• If you have diabetes
• If you have a thyroid problem
• If you have a kidney problem

Lipitor and certain other medications can interact, causing serious side effects. Tell your doctor about any prescription and nonprescription medications you are taking, including the following:
