According to drug interaction information from Drugs.com, there are no known interactions between atorvastatin (brand name Lipitor) and probiotic formulas [2]. This suggests that it is generally safe to take probiotics while using Lipitor. The American Academy of Family Physicians also does not mention any specific interactions between probiotics and atorvastatin in their publication [3]. It is always recommended to consult with a healthcare provider or pharmacist before starting any new medications or supplements, including probiotics, to ensure safety and effectiveness.
