Lipitor is a medication used to lower cholesterol levels in the body [1]. According to the drug label provided by WebMD, Lipitor can be taken with or without food [2]. However, it is important to note that high-fat meals may affect the absorption of the medication [3]. A study published in the US National Library of Medicine found that taking Lipitor with a high-fat meal reduced its absorption by 30% [3]. Therefore, it is recommended to take Lipitor at the same time every day and to avoid consuming high-fat meals around the time of taking the medication [2]. It is important to follow the instructions provided by your healthcare provider regarding the timing of taking Lipitor and any dietary restrictions that may be necessary for the medication to be effective [2][3].
