Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels and reduce the risk of heart disease [1]. It is recommended to take atorvastatin once a day, at the same time each day, with or without food [2]. However, taking it with food can help reduce stomach upset that may occur as a side effect of the medication [3].

It is important to follow the dosage instructions provided by your doctor or pharmacist, and not to take more or less than prescribed. Atorvastatin should also be taken regularly to be effective in reducing cholesterol levels.

In summary, Lipitor (atorvastatin) can be taken with or without food, but taking it with food may help reduce stomach upset. It is important to follow the dosage instructions provided by your healthcare provider to ensure the medication is effective in reducing cholesterol levels and lowering the risk of heart disease.
