Based on the information available, there are no known major interactions between Lipitor (atorvastatin), a cholesterol-lowering medication, and antihistamines [1]. However, it's important to note that everyone's medical situation is unique, and any new medications, including over-the-counter antihistamines, should be discussed with a healthcare provider or pharmacist to ensure there are no potential interactions with current medications [2].

Antihistamines are primarily used to treat allergies and allergic reactions, and they work by blocking the action of histamine, a substance in the body that causes allergic symptoms [3]. Lipitor, on the other hand, is a statin medication that lowers cholesterol levels in the blood by reducing the production of cholesterol in the body [4].

While there are no major interactions between these two types of medications, it's still possible that antihistamines could interact with other medications you're taking, so it's always a good idea to check with a healthcare provider or pharmacist before starting any new medication [2].

In summary, based on the available information, there are no known major interactions between Lipitor and antihistamines. However, it's always a good idea to consult with a healthcare provider or pharmacist before starting any new medication to ensure there are no potential interactions with current medications.
