Lipitor is a brand name for the medication atorvastatin [1]. Atorvastatin is used to lower cholesterol and triglyceride levels in the blood. According to Drugs.com, atorvastatin can be taken with or without food, and it is recommended to take it at the same time every day [2]. However, it is important to note that certain foods, such as grapefruit, can interact with atorvastatin and increase the risk of side effects [3]. Therefore, it is best to consult with a healthcare provider about any dietary restrictions or recommendations while taking atorvastatin. As for how long to wait after eating before taking Lipitor, the sources do not provide a specific answer to this question. It is best to follow the instructions provided by a healthcare provider or the medication label.
