Lipitor is a prescription medication that’s used in certain situations along with a balanced diet to:
- lower cholesterol levels in adults and some children
- reduce the risk of heart and blood vessel problems caused by high cholesterol, such as heart attack and stroke, in adults
- reduce the need for certain heart surgeries in adults
For more details on these uses, see the “What is Lipitor used for?” section below.
Lipitor contains the active ingredient atorvastatin. An active ingredient is what makes a drug work. Atorvastatin is also available as a generic drug.
Lipitor comes as a tablet that you swallow, and you usually take it once per day. Lipitor is classified as a statin. These drugs help lower cholesterol levels in your body.
Read on to learn more about Lipitor’s side effects, dosage, and some frequently asked questions.
Like most drugs, Lipitor may cause mild or serious side effects. The lists below describe some of the more common side effects that Lipitor may cause. These lists do not include all possible side effects.
Keep in mind that side effects of a drug can depend on:
- your age
- other health conditions you have
- other medications you take
Your doctor or pharmacist can tell you more about the potential side effects of Lipitor. They can also suggest ways to help reduce side effects.
Mild side effects
Here’s a short list of some of the mild side effects that Lipitor can cause. To learn about other mild side effects, talk with your doctor or pharmacist, or read Lipitor’s prescribing information.

Muscle pain and joint pain
Some people may experience pain in their muscles or joints while taking Lipitor. In studies, mild muscle and joint pain were common side effects.
Mild muscle pain or tenderness with Lipitor will likely go away on its own. But in rare cases, Lipitor may cause severe muscle pain and muscle weakness. These could be symptoms of more serious conditions, including:
- rhabdomyolysis (for details, see “Rhabdomyolysis” below)
- immune-mediated necrotizing myopathy (a rare condition in which your immune system attacks your muscles and breaks them down)
What might help
Staying well hydrated and increasing exercise intensity and frequency at a slow and steady pace can help minimize joint and muscle pain.
If you have mild muscle or joint pain, your doctor may lower your dose of Lipitor. Or they may prescribe a different drug to treat your condition.
If you have extreme or unexplained muscle pain while taking Lipitor, call your doctor right away. They may have you stop taking the drug while they check for signs of more severe muscle damage. In most cases, muscle and joint pain will go away once you stop taking Lipitor.
In some cases, Lipitor can cause rhabdomyolysis. This is a rare but serious side effect of statins, including Lipitor.
Rhabdomyolysis occurs when your body starts breaking down skeletal muscle tissues. As these tissues break down, they are released into your body, and your kidneys filter them. These tissues are often too much for the kidneys to filter and can lead to kidney damage.
In rare cases, rhabdomyolysis may cause permanent kidney damage (including kidney failure) and can even be fatal. If you have concerns about your risk of rhabdomyolysis during your Lipitor treatment, talk with your doctor.
Minor cases of rhabdomyolysis may not cause any noticeable symptoms. But symptoms to watch for include:
- urine that is brown, red, or cola-colored
- severe muscle pain and weakness, which may make it hard to move your muscles
What might help
A few steps you can take to help prevent rhabdomyolysis include:
- staying well hydrated
- if you exercise, don’t increase how often you work out or the intensity of your exercise too quickly
- talking with your doctor or pharmacist before starting any dietary supplements, including those with caffeine, creatine, and ephedra
If you experience any of the symptoms above, seek medical care right away. Treating this condition early may help limit damage to your kidneys.
Some people taking Lipitor may experience diarrhea. This was one of Lipitor’s most common side effects reported in studies. Diarrhea is typically worse when you first start taking Lipitor, and it usually gets better after taking the drug for a few days.
Symptoms of diarrhea include:
- watery stools
- belly pain and cramps
- weight loss
- body aches or chills
What might help
If you have diarrhea during your Lipitor treatment, be sure to drink plenty of fluids to help you stay hydrated.
Some people may have an allergic reaction to Lipitor. While allergic reaction wasn’t reported in clinical studies of Lipitor, it can still happen.
Symptoms of a mild allergic reaction can include:
- skin rash
- flushing (temporary warmth, redness, or deepening of skin color)
A more severe allergic reaction is rare but possible. Symptoms of a severe allergic reaction can include swelling under your skin, typically in your eyelids, lips, hands, or feet. They can also include swelling of your tongue, mouth, or throat, which can cause trouble breathing.
Call your doctor right away if you have an allergic reaction to Lipitor. But if you think you’re having a medical emergency, call 911 or your local emergency number.
Your doctor will recommend the dosage of Lipitor that’s right for you.
Below are commonly used dosages, but always take the dosage your doctor prescribes.
Form and strengths
Lipitor comes as a tablet that you swallow. It’s available in four strengths: 10 milligrams (mg), 20 mg, 40 mg, and 80 mg.
Lipitor’s lowest dose is 10 mg per day. The dosage range of Lipitor is 10 mg to 80 mg, taken once per day. The dosage you take will depend on the condition you’re using the drug to treat.
For adults taking Lipitor, the usual recommended dose is 10 mg to 80 mg. Depending on your condition, you may start with a dose of 10 mg to 20 mg and then have your dose increased during your treatment.
For lowering cholesterol in children with heterozygous familial hypercholesterolemia (HeFH), the recommended dosage is 10 mg to 20 mg, taken once per day.
Questions about Lipitor’s dosage
Below are some common questions about Lipitor’s dosage.
- What if I miss a dose of Lipitor? If you miss a dose of Lipitor, take it as soon as you remember. But if it’s been more than 12 hours since you were supposed to take the dose, skip that dose and take your next dose at its usual time. You should not take two doses at once to make up for a missed dose. Doing so can raise your risk of side effects from the drug.
- Will I need to use Lipitor long term? Lipitor is meant to be a long-term treatment. If you and your doctor determine that Lipitor is safe and effective for you, you’ll likely take it long term.
- How long does Lipitor take to work? Lipitor starts working as soon as you take a dose. When taken consistently, most people have improvements in their cholesterol within 2 to 4 weeks. You may not feel Lipitor working in your body, but your doctor will monitor your cholesterol levels by ordering certain lab tests during your treatment.
Lipitor is a prescription medication that’s used along with a balanced diet to:
- reduce the risk of heart and blood vessel problems caused by high cholesterol, such as heart attack and stroke, in adults with any of the following conditions:
- reduce the need for certain heart surgeries in adults with either:
- CHD, or
- risk factors for CHD
- lower cholesterol levels in adults with certain forms of high cholesterol, including a genetic (inherited) condition called homozygous familial hypercholesterolemia (HoFH)
- lower cholesterol in children ages 10 to 17 years with the genetic condition heterozygous familial hypercholesterolemia (HeFH)
Lipitor belongs to a group of medications called statins. These drugs reduce the level of low-density lipoprotein (LDL), or bad cholesterol, in your body. This helps prevent heart problems, such as coronary heart disease, chest pain, stroke, and heart attack.
Below are answers to some commonly asked questions about Lipitor.
Does Lipitor cause weight loss, weight gain, diabetes, memory loss, ED, tiredness, or headaches?
No, none of these were reported as side effects in studies of Lipitor.
Keep in mind that Lipitor is prescribed along with a balanced diet. Some people may experience weight loss while taking Lipitor if they make certain changes to their diet.
Other statins used to treat high cholesterol may cause diabetes or memory problems. These side effects weren’t reported in studies of Lipitor. But high blood sugar levels have been reported as a side effect of Lipitor since the drug became available on the market. (Diabetes is a disease that causes high blood sugar.)
Because Lipitor treats high cholesterol, it may actually help reduce symptoms of erectile dysfunction (ED). See this article to learn more about the link between ED and high cholesterol.
Certain side effects of Lipitor, such as infection or liver problems, may cause tiredness. But tiredness isn’t a direct side effect of the drug.
Headache isn’t a side effect of Lipitor, but it could be a symptom of other conditions, such as high blood pressure.
If you have concerns about experiencing any of these side effects during your Lipitor treatment, talk with your doctor or pharmacist.
Is Lipitor a blood thinner or a beta-blocker? And does it lower blood pressure?
Beta-blockers help manage high blood pressure, and blood thinners help prevent blood clots. Some people taking Lipitor may also need to take beta-blockers or blood thinners, depending on their other health conditions.
If you take other medications and are interested in taking Lipitor, talk with your doctor to make sure the drugs are safe to take together.
Is Lipitor considered a safe medication? Why might some people think it’s bad for you?
Yes, Lipitor is considered a safe drug for most people. It’s been used to treat certain conditions for more than 20 years and has been studied in adults and children.
Lipitor may cause certain side effects, which could make some people think taking the drug is harmful. But the most common side effects reported in studies were mild. Examples of these side effects include diarrhea, joint and muscle pain, sore throat, and upper respiratory infection.
Some serious side effects may occur with Lipitor, but they’re not common. For example, in rare cases, Lipitor may cause severe muscle pain. (To learn more about possible side effects, see “What are Lipitor’s side effects?” above.)
If you have questions about whether Lipitor is safe for you to take, talk with your doctor or pharmacist.
Will Lipitor cause different side effects in men vs. women?
In studies, no differences in side effects were reported among males* and females* taking Lipitor.
But certain side effects of Lipitor are specific to females who can become pregnant. These are related to taking Lipitor during pregnancy or while breastfeeding. To learn more, see “Pregnancy and breastfeeding” under the “What should be considered before taking Lipitor?” section below.
* In this article, we use the terms “males” and “females” to refer to someone’s sex assigned at birth. For information about the difference between sex and gender, see this article.

What should I know about Lipitor’s alternative drug Livalo?
Lipitor and Livalo are both statins, which help lower cholesterol levels in your body.
Lipitor contains the active ingredient atorvastatin, while Livalo contains pitavastatin. (An active ingredient is what makes a drug work.) To learn more about Livalo, check out this article. You can ask your doctor if one of these drugs may be right for you.
Will I have side effects after stopping Lipitor?
Ending your Lipitor treatment should not cause any side effects. But if you stop taking Lipitor and do not replace it with a different treatment, your cholesterol may increase again. This could lead to serious heart problems.
If you’d like to stop taking Lipitor, talk with your doctor. They can determine if you should stop taking Lipitor and if you need to start taking a new drug in its place. You should not stop taking Lipitor unless your doctor recommends it.
Lipitor belongs to a group of medications called statins. These drugs reduce the level of low-density lipoprotein (LDL) cholesterol in your body. LDL cholesterol is also known as “bad” cholesterol, and too much of it in your body can lead to serious health problems.
Statins reduce LDL cholesterol by suppressing a certain enzyme in the liver that’s responsible for LDL production. This helps prevent heart problems, such as coronary heart disease, chest pain, stroke, and heart attack.
Your doctor or pharmacist can provide more information about how Lipitor works.
Lipitor contains the active ingredient atorvastatin, while Crestor contains rosuvastatin. (An active ingredient is what makes a drug work.)

Lipitor may not be right for you if you have certain medical conditions or other factors that affect your health. Talk with your doctor about your health history before you take Lipitor. Factors to consider include those in the list below.
- Liver disease. Lipitor is contraindicated in people with liver disease. (A contraindication is a factor or condition that could prevent your doctor from prescribing a drug due to risk of harm.) People who have liver disease or have had it in the past may have a higher risk of side effects from Lipitor. Due to this risk, doctors typically will not prescribe Lipitor. Before taking Lipitor, talk with your doctor if you have liver disease.
- Kidney disease. Lipitor may cause muscle pain and weakness. If you have kidney disease, you may have a higher risk of these side effects. Talk with your doctor about whether Lipitor is safe for you.
- Uncontrolled hypothyroidism. Lipitor may cause muscle pain and weakness. If you have an underactive thyroid that’s not well managed by medication, you may have a higher risk of this side effect. Before taking Lipitor, be sure to tell your doctor about any thyroid conditions you have.
- A recent stroke or ministroke. In rare cases, Lipitor may cause hemorrhagic stroke. If you’ve had a stroke or ministroke within the past 6 months, Lipitor may raise your risk of this side effect. Before starting treatment with Lipitor, talk with your doctor if you’ve had a stroke.
- Diabetes or high blood sugar. In rare cases, Lipitor may cause high blood sugar. If you have diabetes or high blood sugar, taking Lipitor could worsen these conditions. Talk with your doctor about whether Lipitor is a safe treatment option for you.
- Allergic reaction. If you’ve had an allergic reaction to Lipitor or any of its ingredients, your doctor will likely not prescribe Lipitor. Ask your doctor what other medications are better options for you.
Lipitor and alcohol
There are no known interactions between Lipitor and alcohol. But drinking large amounts of alcohol while taking Lipitor can raise your risk of liver damage.
Before taking Lipitor, tell your doctor if you drink alcohol and usually have more than two alcoholic drinks per day. They can determine whether Lipitor is safe for you to take.

Will I have to take cholesterol medication for the rest of my life? Anoymous
How long you’ll take medication for high cholesterol depends on several factors, including the specific condition you’re taking Lipitor to treat. For example, if you take Lipitor for a hereditary disease, such as heterozygous familial hypercholesterolemia (HeFH) or homozygous familial hypercholesterolemia (HoFH), you’ll likely need treatment throughout your life.
If your condition isn’t hereditary, your need for Lipitor or other cholesterol medications could change depending on the lifestyle changes you make. For example, you may try:
- eating a balanced diet with more fiber, fewer starchy foods (such as breads and sweets), and less saturated fat
- exercising at least 150 minutes per week (or about 30 minutes per day, 5 days a week)
- quitting smoking
- drinking less alcohol
You and your doctor can talk about which lifestyle changes might make sense for you to try. They can also provide resources to help you make those changes.
If you have questions about how long you’ll need to use Lipitor, talk with your doctor.
