Based on the information available, it is possible to take Lipitor with over-the-counter allergy pills, but it depends on the active ingredients in the allergy medication. Lipitor, a medication used to treat high cholesterol, can interact with certain drugs, including some antifungal medications, antibiotics, and other cholesterol-lowering drugs [1].

However, most over-the-counter allergy pills contain antihistamines, such as diphenhydramine (Benadryl) or loratadine (Claritin), which are unlikely to interact with Lipitor [2].

It is always important to consult with a healthcare provider or pharmacist before starting any new medication, including over-the-counter products, to ensure there are no potential interactions with current medications [3].

In summary, while it is generally safe to take Lipitor with over-the-counter allergy pills, it is always best to consult with a healthcare provider or pharmacist to ensure there are no potential interactions with current medications.
