Atorvastatin can interact with other medications, vitamins, or herbs you may be taking. An interaction is when a substance changes the way a drug works. This can be harmful or prevent the drug from working well.
To help avoid interactions, your doctor should manage all of your medications carefully. Be sure to tell your doctor about all medications, vitamins, or herbs you’re taking. To find out how this drug might interact with something else you’re taking, talk to your doctor or pharmacist.
Avoid drinking large amounts of grapefruit juice while taking atorvastatin. Drinking grapefruit juice can lead to a buildup of atorvastatin in your blood, which raises your risk of muscle breakdown. Ask your doctor how much grapefruit juice is safe for you.
The use of drinks that contain alcohol can increase your risk of liver disease from atorvastatin. If you drink more than 2 glasses of alcohol per day, talk to your doctor.
