Based on the information provided, it is not explicitly contraindicated for Benadryl (diphenhydramine) and Lipitor (atorvastatin) to be taken together [1]. However, it is always recommended to consult with a healthcare provider or pharmacist before combining any medications [2]. It is important to note that Benadryl is known to cause drowsiness, and when combined with other medications that can cause drowsiness, such as Lipitor, it may increase the risk of side effects such as dizziness, drowsiness, and difficulty concentrating [1][3]. Additionally, Benadryl is a type of medication called an anticholinergic, and long-term use of anticholinergic medications is associated with an increased risk of cognitive decline and dementia [1].

In summary, while it is not explicitly contraindicated for Benadryl and Lipitor to be taken together, it is important to be aware of the potential for increased side effects and to consult with a healthcare provider or pharmacist before combining any medications.
