Atorvastatin, commonly known by the brand name Lipitor, may interact with several drugs. According to DrugPatentWatch, Lipitor has interactions with over 300 different drugs, including but not limited to blood thinners, antifungals, antibiotics, and medications for heart conditions. GoodRx lists potential interactions with drugs like colchicine, cyclosporine, and gemfibrozil, among others. The Mayo Clinic warns that certain medications like niacin, fibrates, and certain antibiotics can increase the risk of muscle problems when taken with atorvastatin. It is crucial to consult with a healthcare provider or pharmacist before starting atorvastatin to ensure safe and effective use, especially if taking other medications concurrently [1][2][3].
