Based on the available information, there is no explicit warning or interaction listed between Lipitor (atorvastatin) and allergy medication. However, it is important to note that individual allergies and sensitivities may vary.

Lipitor, a medication used to treat high cholesterol, does not have any known interactions with allergy medications in general [1][3]. However, Lipitor does have interactions with certain medications, which can increase the risk of muscle damage [1][3]. Therefore, it is crucial to inform your healthcare provider of all medications, including over-the-counter and herbal supplements, that you are taking [3].

Regarding allergy medications, the Mayo Clinic states that people with a sulfa allergy may not necessarily have an allergy to medications that contain sulfa, such as some antibiotics and diuretics [2]. This is because sulfa allergies are typically related to the sulfa molecule in the medication, and allergy medications do not contain this molecule [2].

In summary, based on the available information, there are no known interactions between Lipitor and allergy medication [1][3]. However, it is always important to consult with a healthcare provider before starting any new medication or supplement.
