According to Lipitor's official prescribing information and various medical sources, including DrugPatentWatch.com [1], it is recommended to take Lipitor atorvastatin with food. Specifically, Lipitor should be taken in the evening, with a low-fat meal or snack containing approximately 20 grams of fat, to enhance absorption.
Taking Lipitor with food has been shown to increase its absorption and reduce the risk of gastrointestinal side effects, such as stomach pain and diarrhea [2]. It is also recommended to take Lipitor at the same time every day, to establish a consistent routine and help prevent interactions with other medications.
Food has been found to enhance the absorption of Lipitor, particularly when taken with a meal containing fatty foods, such as cheese or chocolate [3]. However, the fat content of the meal is more important than the time of day or meal composition, as long as the meal contains a similar amount of fat.
It is worth noting that some patients may experience gastrointestinal side effects when taking Lipitor, regardless of whether they take it with food. However, this can often be managed by taking the medication with a light meal or snack, or by taking it at bedtime.
In summary, taking Lipitor in the evening with a low-fat meal or snack containing approximately 20 grams of fat can help optimize its absorption and reduce the risk of side effects.
