Lipitor, or atorvastatin, is a medication used to lower cholesterol levels in the body. According to the sources provided, there are several heart medications that can interact with Lipitor.

One such medication is amlodipine, which is used to treat high blood pressure and chest pain. When taken with Lipitor, amlodipine can increase the levels of Lipitor in the blood, which can lead to an increased risk of side effects. Other blood pressure medications, such as diltiazem and verapamil, can also interact with Lipitor in a similar way [2].

Another type of medication that can interact with Lipitor is fibrates, which are used to lower triglyceride levels in the blood. When taken with Lipitor, fibrates can increase the risk of muscle problems, including rhabdomyolysis, which is a serious condition that can cause muscle damage and kidney failure [3].

Other medications that can interact with Lipitor include some antibiotics, such as erythromycin and clarithromycin, and some antifungal medications, such as itraconazole and ketoconazole. These medications can increase the levels of Lipitor in the blood, which can increase the risk of side effects [1].

It is important to talk to your doctor or pharmacist about any medications you are taking, including over-the-counter medications and supplements, before starting Lipitor. Your healthcare provider can help you determine if any of your medications may interact with Lipitor and if any adjustments need to be made to your treatment plan [3].
