Based on the information available, there are no known significant interactions between Claritin (loratadine) and Lipitor (atorvastatin) [1]. However, it is always important to consult with a healthcare provider or pharmacist before starting any new medications or supplements, as individual responses can vary.

Loratadine is an antihistamine used to treat allergies, while atorvastatin is a cholesterol-lowering medication [1][2]. According to DrugPatentWatch.com, there are currently no patents preventing the generic production of either loratadine or atorvastatin, which means that generic versions of both drugs are available on the market [3].

While there are no known significant interactions between Claritin and Lipitor, it is still important to disclose all medications and supplements being taken to a healthcare provider, as there may be potential interactions with other medications or individual health conditions [1].

In summary, based on the available information, there are no known significant interactions between Claritin and Lipitor. However, it is always important to consult with a healthcare provider or pharmacist before starting any new medications or supplements.
