What is Atorvastatin?

Atorvastatin belongs to a class of medications called HMG-CoA reductase inhibitors (statins). It works by slowing the production of cholesterol in the body to decrease the amount of cholesterol that may build up on the walls of the arteries and block blood flow to the heart, brain, and other parts of the body.

Atorvastatin is used together with diet, weight loss, and exercise to reduce the risk of heart attack and stroke and to decrease the chance that heart surgery will be needed in people who have heart disease or who are at risk of developing heart disease.

Atorvastatin is also used to lower the amount of fatty substances such as low-density lipoprotein (LDL) cholesterol ('bad cholesterol') and triglycerides in the blood and to increase the amount of high-density lipoprotein (HDL) cholesterol ('good cholesterol') in the blood.

Atorvastatin may also be used to decrease the amount of cholesterol and other fatty substances in the blood in children and teenagers 10 to 17 years of age who have familial heterozygous hypercholesterolemia (an inherited condition in which cholesterol cannot be removed from the body normally).

Accumulation of cholesterol and fats along the walls of your arteries (a process known as atherosclerosis) decreases blood flow and, therefore, the oxygen supply to your heart, brain, and other parts of your body. Lowering your blood level of cholesterol and fats with atorvastatin has been shown to prevent heart disease, angina (chest pain), strokes, and heart attacks.

Warnings

You should not take atorvastatin if you have liver disease or cirrhosis.

Atorvastatin can cause the breakdown of muscle tissue, which can lead to kidney failure. Call your doctor right away if you have unexplained muscle pain, tenderness, or weakness especially if you also have fever, unusual tiredness, or dark urine.

Serious drug interactions can occur when certain medicines are used together with atorvastatin. Tell each of your healthcare providers about all medicines you use now, and any medicine you start or stop using.

Avoid eating foods that are high in fat or cholesterol. Atorvastatin will not be as effective in lowering your cholesterol if you do not follow a cholesterol-lowering diet plan.

Atorvastatin is only part of a complete program of treatment that also includes diet, exercise, and weight control. Follow your diet, medication, and exercise routines very closely.

How should I take Atorvastatin

Atorvastatin comes as a tablet to take by mouth. It is usually taken once a day with or without food. Take atorvastatin at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take atorvastatin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Your doctor may start you on a low dose of atorvastatin and gradually increase your dose, not more than once every 2 to 4 weeks.

Continue to take atorvastatin even if you feel well. Do not stop taking atorvastatin without talking to your doctor.

Detailed Atorvastatin dosage information

Atorvastatin Dosage information (more detail)

Before Taking

You should not use atorvastatin if you are allergic to it, or if you have liver failure or cirrhosis.

To make sure atorvastatin is safe for you, tell your doctor if you have ever had:

• muscle pain or weakness;

• diabetes;

• stroke;

• a thyroid disorder;

• a habit of drinking more than 2 alcoholic beverages per day; or

• kidney disease.

Atorvastatin can cause the breakdown of muscle tissue, which can lead to kidney failure. This happens more often in women, in older adults, or people who have kidney disease or poorly controlled hypothyroidism (underactive thyroid).

Atorvastatin may harm an unborn baby. Tell your doctor if you are pregnant.

Ask a doctor if it is safe to breastfeed while using this medicine.

What happens if I miss a dose?

Take the medicine as soon as you can, but skip the missed dose if you are more than 12 hours late for the dose. Do not take two doses at one time.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

What should I know about storage and disposal of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

What special dietary instructions should I follow?

Eat a low-fat, low-cholesterol diet. Be sure to follow all exercise and dietary recommendations made by your doctor or dietitian. You can also visit the National Cholesterol Education Program (NCEP) website for additional dietary information at http://www.nhlbi.nih.gov/health/public/heart/chol/chol_tlc.pdf.

Avoid drinking large amounts [more than 1.2 liter (approximately 1 quart) per day] of grapefruit juice while taking atorvastatin.

What should I avoid while using Atorvastatin?
