After conducting a thorough search using the information provided, I found that there are no specific pain medications that have been identified to have harmful interactions with Lipitor (atorvastatin), a cholesterol-lowering medication. However, it is always important to consult with a healthcare provider before starting or stopping any medication, as individual responses to medications can vary.

It is also crucial to disclose all medications, both prescription and over-the-counter, to a healthcare provider to ensure there are no potential drug interactions. This includes pain medications, as they can interact with other medications and impact their effectiveness or cause adverse effects.

While there are no specific pain medications to avoid with Lipitor, it is important to be aware of the potential risks associated with statins, the class of medication that Lipitor belongs to. According to the Mayo Clinic, some people who take statins may experience muscle pain or damage, a condition called myopathy [1]. Therefore, it is essential to inform a healthcare provider if muscle pain or weakness occurs while taking Lipitor.

In addition, it is important to note that grapefruit and grapefruit juice can interact with Lipitor and increase the levels of the medication in the body, potentially leading to adverse effects [2]. Therefore, it is recommended to avoid consuming grapefruit or grapefruit juice while taking Lipitor.

In summary, while there are no specific pain medications to avoid with Lipitor, it is crucial to inform a healthcare provider of all medications and supplements being taken and to report any muscle pain or weakness. Additionally, it is important to avoid consuming grapefruit or grapefruit juice while taking Lipitor.
