GoodRx provides a list of drug interactions for Paxlovid, a medication used to treat COVID-19 [3]. While it does not mention Lipitor, it is important to note that drug interactions can occur with any medication, including allergy medications. Therefore, it is recommended to consult with a healthcare provider or pharmacist before taking any new medications, including allergy medications, while taking Lipitor.

In summary, there are no specific allergy medications to avoid while taking Lipitor, according to the sources provided. However, it is always important to consult with a healthcare provider or pharmacist before taking any new medications while on Lipitor or any other medication.
