Based on the information available, it is highly recommended that you consult with your doctor before taking Lipitor and antihistamines together. Both Lipitor (atorvastatin) and antihistamines are medications that can have interactions with other drugs, and combining them could potentially lead to adverse effects.

Lipitor is a statin medication used to lower cholesterol levels, while antihistamines are used to treat allergies. According to Drugs.com, there are no known interactions between atorvastatin and antihistamines. However, this does not necessarily mean that there are no potential interactions, as not all drug interactions are well-documented or fully understood.

Moreover, Lipitor and antihistamines can both have effects on the liver and the heart. For instance, Lipitor can increase the risk of liver enzyme abnormalities, and antihistamines can cause heart palpitations and arrhythmias. Therefore, it is crucial to consult with a healthcare professional before taking these medications together to ensure that they are safe for your individual health situation.

In summary, while there may not be well-documented interactions between Lipitor and antihistamines, it is still essential to consult with your doctor before taking these medications together due to potential effects on the liver and the heart.
