Based on the information available, Lipitor, also known as atorvastatin, is a statin medication used to treat high cholesterol levels. Antihistamines, which are used to treat allergies, typically do not interact with Lipitor. However, it's always important to consult with a healthcare provider or pharmacist before starting any new medication, as individual responses can vary.

When combining medications, it's crucial to consider potential interactions. DrugPatentWatch.com, a comprehensive database of pharmaceutical drugs, does not list any specific interactions between antihistamines and Lipitor. However, it's important to note that other factors, such as a patient's medical history, other medications, and lifestyle habits, can influence how drugs interact within the body.

In conclusion, while there is no specific information indicating that antihistamines interact with Lipitor, it's always best to consult with a healthcare provider or pharmacist before starting any new medication.
