What Are The Most Common Side Effects Of Atorvastatin?

Atorvastatin is in 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 decrease 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).

How should atorvastatin be used?

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.
