Statins work by blocking an enzyme called HMG-CoA reductase. This enzyme’s role is to speed up the body’s process of building cholesterol. Blocking this enzyme by taking a statin drug slows down natural cholesterol production and lowers the amount of cholesterol in your blood.
Cholesterol is a waxy, fat-like substance made by the body. It also comes from eating certain foods. The body needs cholesterol, also called lipids, for many essential functions. But, having too much cholesterol in the blood can lead to life-threatening heart problems like a heart attack or stroke. Lipitor is prescribed along with a healthy diet to reduce high cholesterol levels and lower the risk of cardiovascular disease and death.
Lipitor is a tablet that contains the active ingredient atorvastatin and is usually taken once a day.
What Is Lipitor Used For?
Lipitor is used to treat high cholesterol. Specifically, the Food and Drug Administration (FDA) has approved it for the following uses, along with a healthy diet for the following.
Brand Name(s): Lipitor
Drug Availability: Prescription
Therapeutic Classification: Antihyperlipidemic
Available Generically: Yes
Controlled Substance: N/A
Administration Route: Oral
Active Ingredient: Atorvastatin
Dosage Form(s): Tablet
Lipitor helps prevent serious cardiovascular events such as heart attack and stroke in adults considered high-risk for developing these problems. It is also approved to reduce the risk of angina and the need for certain types of heart surgery in high-risk individuals. People are considered high-risk if they have multiple cardiovascular (heart) risk factors, such as:
Smoking or tobacco use High blood pressure (hypertension) Being male (sex assigned at birth) Being over 65 years of age Low levels of high-density lipoprotein (HDL) in the blood, commonly known as “good” cholesterol Type 2 diabetes Family history of cardiovascular disease
Lipitor reduces the risk of serious cardiovascular events in adults with heart disease, such as coronary artery disease, peripheral vascular disease (narrowing of the blood vessels), or a history of stroke or other blood flow problems.
It also decreases or improves cholesterol levels in adults with conditions that cause high cholesterol levels, including:
Primary hyperlipidemia: High levels of low-density lipoprotein (LDL), commonly known as “bad” cholesterol, in the blood Hypertriglyceridemia: High levels of triglycerides, another type of lipid, in the blood Mixed dyslipidemia: Low levels of HDL along with high levels of LDL and triglycerides in the blood Homozygous familial hypercholesterolemia (HeFH): A genetic condition that can cause very high levels of LDL
Lipitor reduces cholesterol levels in children ages 10 years and older with HeFH.
How to Take Lipitor
Take Lipitor by mouth as directed by your healthcare provider, typically once a day. It doesn’t matter what time of day you take Lipitor, but it’s best to take it around the same time each day. The medication may be taken with or without food.

“Azole” antifungals such as Nizoral (ketoconazole) and Sporanox (itraconazole)Certain macrolide antibiotics such as Biaxin (clarithromycin) and erythromycinCertain protease inhibitors used to treat HIV such as Aptivus (tipranavir), Norvir (ritonavir), and Invirase (saquinavir)DigoxinFibrates, such as fenofibrateGemfibrozilNeoral (cyclosporine)Niacin (vitamin B3)St. John’s Wort, an herbal remedy thought to have antidepressant effects
What Medications Are Similar?
Lipitor belongs to a class of drugs called statins. Other statin drugs are available besides Lipitor. Like most types of medications, individual results can vary with different drugs in the same class.

If you have questions about other treatment options, talk to your healthcare provider or pharmacist.
Statin drugs that are similar to Lipitor (atorvastatin) include:
Altoprev, Mevacor (lovastatin) Livalo (pitavastatin) Pravachol (pravastatin) Crestor (rosuvastatin) Zocor (simvastatin)
How Can I Stay Healthy While Taking Lipitor?
When your healthcare provider prescribes a new medication, it’s common to feel concerned about things like side effects. Millions of people have taken Lipitor for more than 25 years since it came on the market. Most people don’t experience any side effects from this medication. Some people notice mild side effects, but severe side effects are rare.
Some healthcare providers recommend taking a supplement called Coenzyme Q10 or “CoQ10” with statins. This is because clinical studies reviewed by the American Heart Association showed that supplementing CoQ10 along with a statin drug can relieve muscle pain, cramps, and weakness.
Tell your healthcare provider if you develop muscle problems while taking Lipitor.
Understandably, some people do not like taking medications. You may prefer to try changing your diet and lifestyle instead of starting a drug like Lipitor. Sometimes changes in your diet alone may not be enough. High cholesterol can be genetic and run in families. Also, having untreated high cholesterol can put you at increased risk for a heart attack, stroke, or other serious health problem. Taking atorvastatin can lower your cholesterol and reduce these risks.
Healthcare providers recommend taking an active role in your health. In the case of high cholesterol, you can take an active role by taking Lipitor once a day and making changes to your diet and lifestyle. This may include reducing fried foods, red meat and saturated fats, and incorporating more whole foods into your day. If you’re not used to exercising, start with a short daily walk. Consider talking to your healthcare provider about an exercise program that’s best for you.
