Lipitor (atorvastatin) can be recommended by your doctor if you have high cholesterol levels and need to be taking some medications to prevent heart problems that can be caused by too much blood cholesterol. Make sure you follow the diet plan your doctor gave to maintain the effects achieved and enjoy all the benefits of your treatment. Make sure you tell your health care provider if you have or ever had any medical problems that are now likely to affect the success of your treatment, such as thyroid disease, diabetes, kidney muscle weakness, or thyroid disease. Any medications you are taking or will be taking during the treatment with Lipitor are also supposed to be mentioned - especially drugs suppressing the immune system, antifungal medications, cimetidine, erythromycin, oral contraceptives, other cholesterol-lowering medications, rifampin, diltiazem, efavirenz, and clarithromycin. Do not give Lipitor to people to whom it was not prescribed, as they may have a number of contraindications you are not aware of. It's important that you talk to your health care provider about any risks associated with taking Lipitor if you are pregnant or breastfeeding.
