Acetaminophen and Lipitor can be safely used together, according to the sources provided. DrugPatentWatch [1] and Drugs.com [2] do not list any significant interactions between the two drugs. However, it is important to note that Lipitor may cause liver damage, and acetaminophen is also processed by the liver. Therefore, individuals with liver problems should use caution when taking these medications together. Additionally, the NIH COVID-19 Treatment Guidelines [3] state that there are no clinically significant drug interactions between Lipitor and Paxlovid, a medication used to treat COVID-19. Overall, it is safe to use acetaminophen with Lipitor, but individuals should consult with their healthcare provider before taking any new medications.
