Lipitor (atorvastatin) is a medication used to lower cholesterol levels in the body. It is usually taken once a day, and the timing of the dose in relation to meals can be important to ensure its effectiveness. According to the sources provided, Lipitor can be taken with or without food, but it is generally recommended to take it at the same time each day [2][3]. It is important to note that high-fat meals can decrease the absorption of Lipitor, so it is advisable to avoid consuming large amounts of fatty foods before taking the medication [2]. As for the timing, there is no specific time frame mentioned in the sources for how long after eating one should take Lipitor. However, it is generally recommended to take it at a consistent time each day, regardless of meals [2][3]. It is also important to follow the instructions provided by your healthcare provider or pharmacist and to never adjust the dosage or timing of the medication without consulting them first [1][3].
