Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels. According to Drugs.com, there is a potential interaction between atorvastatin and Tylenol (acetaminophen) [2]. This interaction can increase the risk of liver damage. Patients taking atorvastatin should avoid taking more than 3 grams of acetaminophen per day, and should consult their doctor before taking any new medications that contain acetaminophen.

Another source, Drug Patent Watch, provides a list of drugs that have potential interactions with atorvastatin [1]. However, this list does not include any pain relievers.

The NIH COVID-19 Treatment Guidelines provide information on drug interactions with Paxlovid, a medication used to treat COVID-19 [3]. This medication contains nirmatrelvir and ritonavir, and there is a potential interaction between ritonavir and atorvastatin. The combination of these drugs can increase the risk of muscle damage and other side effects. Patients taking atorvastatin should inform their doctor if they are prescribed Paxlovid or any other medications containing ritonavir.

In summary, according to the sources provided, the only pain reliever that has a potential interaction with atorvastatin is acetaminophen (Tylenol). Patients taking atorvastatin should avoid taking more than 3 grams of acetaminophen per day, and should consult their doctor before taking any new medications that contain acetaminophen.
