Lipitor (atorvastatin) is a medication used to lower cholesterol levels in the body [1]. According to the NHS, Lipitor should be taken once a day, preferably at night, with or without food. However, it is recommended to take it at the same time each day [2].

The Drugs.com website states that Lipitor can be taken with or without food. However, taking it with food may help reduce stomach upset [3].

None of the sources provide information on how long after eating Lipitor should be taken. It is important to follow the instructions given by your healthcare provider or pharmacist regarding the use of this medication.
