Atorvastatin, marketed under the brand name Lipitor, is a medication used to treat high cholesterol and reduce the risk of heart disease [1]. According to the National Health Service (NHS) in the UK, atorvastatin can be taken with or without food, but it is recommended to take it at the same time every day [2]. The medication can be taken with or without food because food does not significantly affect its absorption [3]. However, it is important to follow the instructions of a healthcare provider and read the medication label carefully for specific instructions on how to take the medication [2].
