It is important to be aware of potential interactions when taking any medication, including Lipitor (atorvastatin). According to the NHS [2], certain medications can interact with Lipitor and increase the risk of side effects. For example, medications that contain fusidic acid (used to treat infections) should not be taken with Lipitor. Additionally, taking certain antibiotics, antifungals, or antivirals with Lipitor may increase the risk of muscle damage. Other medications, such as those used to treat HIV or hepatitis C, may also interact with Lipitor.

Drug Patent Watch [1] lists several drugs that may interact with Lipitor, including certain blood pressure medications, anticoagulants, and immunosuppressants. GoodRx [3] also provides a list of medications that may interact with Lipitor, including certain heart medications, antidepressants, and antipsychotics.

It is important to talk to your doctor or pharmacist about any medications or supplements you are taking before starting Lipitor. They can help determine if there are any potential interactions and adjust your medication regimen as needed. It is also important to report any side effects or changes in your health to your healthcare provider.
