Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the blood [1]. Cranberry is a fruit that is often used to prevent urinary tract infections [2]. There is no evidence to suggest that taking Lipitor and consuming cranberry will cause any significant side effects. However, it is always important to talk to your doctor before taking any new medication or supplement, as they can advise on potential interactions or contraindications based on your individual health status and medical history [3].
