Quick GuideLower Your Cholesterol, Save Your Heart
Why is Lipitor (atorvastatin) prescribed to patients?
- Lipitor is used for the treatment of elevated total cholesterol, LDL, and triglycerides and to elevate HDL cholesterol. The effectiveness of Lipitor in lowering cholesterol is dose-related, meaning that higher doses reduce cholesterol more.
- Lipitor prevents:
- Lipitor reduces the risk of heart attack, stroke, angina and revascularization procedures in adults with multiple risk factors for coronary artery disease.
- Lipitor also prevents heart attacks and strokes in patients with type 2 diabetes with multiple risk factors for coronary artery disease.
What are the side effects of Lipitor (atorvastatin)?
Lipitor is generally well-tolerated. Minor side effects include:
Other commonly reported side effects include:
- Common cold (nasopharyngitis)
- Joint pain (arthralgia)
- Pain in the extremities
- Urinary tract infection
Lipitor may cause liver and muscle damage. Serious liver damage caused by statins is rare. Liver tests should be performed at the beginning of treatment then as needed thereafter.
Inflammation of the muscles caused by statins can lead to serious breakdown of muscle cells called rhabdomyolysis. Rhabdomyolysis causes the release of muscle protein (myoglobin) into the blood, and myoglobin can cause kidney failure and even death. When used alone, statins cause rhabdomyolysis in less than one percent of patients. To prevent the development of serious rhabdomyolysis, patients taking atorvastatin should contact their health-care professional immediately if they develop unexplained muscle pain, weakness, or muscle tenderness.
Statins have been associated with increases in HbA1c and fasting serum glucose levels as seen in diabetes.
There are also post-marketing reports of:
Symptoms may start one day to years after starting treatment and resolve within a median of three weeks after stopping the statin.
What is the dosage for Lipitor (atorvastatin)?
- Lipitor is prescribed once daily. The usual starting dose for adults is 10-20 mg per day, and the maximum dose is 80 mg per day. Adults who need more than a 45% reduction in LDL cholesterol may be started at 40 mg daily.
- Pediatric patients should receive 10 mg once daily up to a maximum dose of 20 mg daily. Lipitor may be taken with or without food and at any time of day.

Which drugs or supplements interact with Lipitor (atorvastatin)?
Decreased elimination of Lipitor could increase levels of Lipitor in the body and increase the risk of muscle toxicity from Lipitor. Therefore, Lipitor should not be combined with drugs that decrease its elimination. Examples of such drugs includes:
- erythromycin (E-Mycin),
- ketoconazole (Nizoral),
- itraconazole (Sporanox),
- clarithromycin (Biaxin),
- telithromycin (Ketek),
- cyclosporine (Sandimmune),
- nefazodone (Serzone), and
- HIV protease inhibitors such as indinavir (Crixivan) and ritonavir (Norvir).
Large quantities of grape fruit juice (>1.2 liters daily) also will increase blood levels of Lipitor and should not be taken.
The following drugs also may increase the risk of muscle toxicity when combined with Lipitor.
- amiodarone (Cordarone)
- verapamil (Calan Verelan, Isoptin)
- cyclosporine (Sandimmune)
- niacin (Niacor, Niaspan, Slo-Niacin)
- gemfibrozil (Lopid)
- fenofibrate (Tricor)
Lipitor increases the effect of warfarin (Coumadin) and the concentration in blood of digoxin (Lanoxin). Patients taking Lipitor and warfarin or digoxin should be monitored carefully. Cholestyramine (Questran) decreases the absorption of Lipitor. Lipitor should be given at least two hours before and at least four hours after cholestyramine.
Rifampin increases breakdown of Lipitor. To reduce the likelihood of this interaction both drugs should be given at the same time. Lipitor should not be given after rifampin.
Is Lipitor (atorvastatin) safe to use during pregnancy or while breastfeeding?
- Lipitor should not be taken during pregnancy because the developing fetus requires cholesterol for development, and Lipitor reduces the production of cholesterol. Lipitor should only be administered to women of childbearing age if they are not likely to become pregnant.
- It is not known if Lipitor is secreted in breast milk. Because of the potential risk of adverse events, breastfeeding mothers should not use Lipitor.
What else should I know about Lipitor (atorvastatin)?
What preparations of Lipitor (atorvastatin) are available?
- Tablets of 10, 20, 40, and 80 mg
How should I keep Lipitor (atorvastatin) stored?
- Tablets should be stored at room temperature, 20 C to 25 C (68 F to 77 F).
How does Lipitor (atorvastatin) work?
- All statins, including atorvastatin, prevent the production of cholesterol in the liver by blocking HMG-CoA reductase, an enzyme that makes cholesterol. Statins reduce total cholesterol as well as LDL cholesterol in blood. LDL cholesterol is believed to be the "bad" cholesterol that is primarily responsible for the development of coronary artery disease. Reducing LDL cholesterol levels retards progression and may even reverse coronary artery disease. Atorvastatin also raises the concentrations of HDL ("good") cholesterol that protects against coronary artery disease and reduces the concentration of triglycerides in the blood. (High blood concentrations of triglycerides also have been associated with coronary artery disease.)
When was Lipitor (atorvastatin) approved by the FDA?
- The FDA approved atorvastatin in December 1996.

Cholesterol ManagementHigh cholesterol and triglyceride levels increase the risk of cardiovascular disease. Getting your cholesterol and triglyceride levels in an optimal range will help protect your heart and blood vessels. Cholesterol management may include lifestyle interventions (diet and exercise) as well as medications to get your total cholesterol, LDL, HDL, and triglycerides in an optimal range.
Congestive Heart Failure (CHF) OverviewCongestive heart failure (CHF) refers to a condition in which the heart loses the ability to function properly. Heart disease, high blood pressure, diabetes, myocarditis, and cardiomyopathies are just a few potential causes of congestive heart failure. Signs and symptoms of congestive heart failure may include fatigue, breathlessness, palpitations, angina, and edema. Physical examination, patient history, blood tests, and imaging tests are used to diagnose congestive heart failure. Treatment of heart failure consists of lifestyle modification and taking medications to decrease fluid in the body and ease the strain on the heart. The prognosis of a patient with congestive heart failure depends on the stage of the heart failure and the overall condition of the individual.
Diabetes MellitusDiabetes is a chronic condition characterized by high levels of sugar (glucose) in the blood. The two types of diabetes are referred to as type 1 (insulin dependent) and type 2 (non-insulin dependent). Symptoms of diabetes include increased urine output, thirst, hunger, and fatigue. Treatment of diabetes depends on the type.

- congested lungs,
- fluid and water retention,
- fatigue and weakness, and
- rapid or irregular heartbeats.
There are two types of congestive heart failure, systolic or left-sided heart failure; and diastolic or right-sided heart failure. Treatment, prognosis, and life-expectancy for a person with congestive heart failure depends upon the stage of the disease.
Illustrations of the HeartThe muscle that pumps blood received from veins into arteries throughout the body. See a picture of the Heart and learn more about the health topic.
Heart: How the Heart WorksThe heart is a very important organ in the body. It is responsible for continuously pumping oxygen and nutrient-rich blood throughout your body to sustain life. It is a fist-sized muscle that beats (expands and contracts) 100,000 times per day, pumping a total of five or six quarts of blood each minute, or about 2,000 gallons per day.
Liver Blood TestsAn initial step in detecting liver damage is a simple blood test to determine the presence of certain liver enzymes in the blood. Under normal circumstances, these enzymes reside within the cells of the liver. But when the liver is injured, these enzymes are spilled into the blood stream, and can lead to diseases like fatty liver, type 2 diabetes, obesity, and hepatitis. Several medications also can increase liver enzyme test results.

A stroke is an interruption of the blood supply to part of the brain caused by either a blood clot (ischemic) or bleeding (hemorrhagic). Symptoms of a stroke may include
- double vision or vision loss,
- vertigo, and
- difficulty speaking or understanding speech.
A physical exam, imaging tests, neurological exam, and blood tests may be used to diagnose a stroke. Treatment may include administration of clot-busting drugs, supportive care, and in some instances, neurosurgery. The risk of stroke can be reduced by controlling high blood pressure, high cholesterol, diabetes, and stopping smoking.
