Based on the information provided, I cannot find evidence that Lipitor is used to treat allergies. Lipitor, also known as atorvastatin, is a medication used to treat high cholesterol levels and reduce the risk of heart attack and stroke [1]. It belongs to a class of drugs called statins, which work by blocking a substance your body needs to make cholesterol [1].

It is important to consult with a healthcare professional for appropriate allergy treatment, as they can provide guidance based on individual health profiles and specific allergy symptoms [2].
