Based on the information available, there is no definitive evidence to suggest that taking Lipitor (atorvastatin) and glucosamine together is harmful [1]. However, it's important to note that drug interactions can be complex and can depend on various factors such as the dosage, frequency of use, and individual patient characteristics.

Lipitor is a statin medication used to lower cholesterol levels, while glucosamine is a dietary supplement often used for osteoarthritis symptom relief [1][2]. The lack of interaction between these two substances may be due to the fact that glucosamine is not metabolized and does not interact with the cytochrome P450 system, which is the primary pathway for Lipitor metabolism [1].

However, it's always recommended to consult with a healthcare provider or pharmacist before starting or combining any medications or supplements, as they can provide personalized advice based on an individual's health history and current medications [1].

In summary, while there is no current evidence to suggest harmful interactions between Lipitor and glucosamine, it's always best to consult with a healthcare professional before combining medications or supplements.
