Lipitor (atorvastatin) is a medication used to lower cholesterol levels in the blood. According to the sources provided, there are several pain medications that may interact with Lipitor.

Firstly, Drug Patent Watch [1] suggests that pain medications containing tramadol, such as Ultram and Ultracet, may interact with Lipitor. This is because both medications are metabolized by the liver, and taking them together may increase the risk of side effects, such as liver damage.

Secondly, GoodRx [2] states that nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen, may also interact with Lipitor. This is because NSAIDs can increase the risk of muscle pain and damage, which is a known side effect of statins like Lipitor.

Finally, Verywell Health [3] adds that opioids, such as codeine and hydrocodone, may also interact with Lipitor. This is because opioids can also cause muscle pain and damage, which can be exacerbated when taken with statins.

It is important to note that not all pain medications may interact with Lipitor, and that the risk of interaction may depend on the individual and their medical history. It is always recommended to consult with a healthcare provider before taking any new medications, especially if you are already taking Lipitor.
