Generic Name: Atorvastatin

  • What is this medication and its most common uses?

    Lipitor belongs to a class of medicines called "statins," which are used to lower your cholesterol (fats in your blood) when a low-fat diet is not enough. Lipitor lowers your total cholesterol, "bad" low-density lipoprotein (LDL) cholesterol, and triglycerides (a type of blood fat), and increases "good" high-density lipoprotein (HDL) cholesterol.

  • What should I know when beginning and continuing on this medication?

    How does this medication work?

    Statins block a protein in the liver that makes cholesterol. When less cholesterol is made, the liver uses more of it from the blood. This results in lower levels of cholesterol. By lowering "bad" cholesterol, lowering triglycerides and by increasing the amount of "good" cholesterol in your blood, Lipitor can slow the build-up of fatty deposits in the walls of the arteries in your heart, brain, or other parts of the body.

    What are the beneficial effects of this medication and when should I begin to have results?

    What: Along with a low-fat diet, Lipitor is proven to lower LDL cholesterol by 39%-60%, depending on the dose prescribed by your healthcare provider. By reducing LDL and triglyceride levels and by increasing HDL, Lipitor may lower your risk of a heart attack, stroke, chest pain, and the need for procedures to restore the blood flow back to the heart or to another part of the body.

    When: Lipitor may start working within 2 weeks. Though you may not feel an improvement or change in the way you feel, it is very important to keep taking your medicine as prescribed to keep your condition under control.

    How do I know it is working?

    Your healthcare provider may do blood tests to check your cholesterol levels during your treatment with Lipitor. Appropriate diet and exercise also contribute to your overall heart health and will also affect the results of your blood tests.

    Taking Lipitor is not a substitute for following a healthy low-fat and low-cholesterol diet and exercising to lower your cholesterol.
