Lipitor is a medication used to lower cholesterol levels in the blood [2]. According to the sources provided, there is no indication that taking Lipitor with fast food is harmful. However, it is important to note that consuming high-fat foods can interfere with the absorption of the medication and reduce its effectiveness [3]. Therefore, it is recommended to take Lipitor with a low-fat meal or at least one hour before or four hours after a high-fat meal [2]. Additionally, it is important to follow the dosage and administration instructions provided by a healthcare professional and not to make any changes without consulting them first [2].

In summary, there is no evidence to suggest that taking Lipitor with fast food is harmful, but it is recommended to take it with a low-fat meal or at least one hour before or four hours after a high-fat meal to ensure optimal absorption and effectiveness [2][3].
