According to the sources provided, Lipitor (atorvastatin) can be taken with or without food. The NHS website recommends taking the medication at the same time each day, with a full glass of water, and with or without food [2]. The Drugs.com website also states that atorvastatin can be taken with or without food, but suggests that taking it with a meal may help to reduce stomach upset that can sometimes occur with the medication [3]. However, it is important to note that the timing of meals and the type of food consumed can affect the absorption and effectiveness of the medication, so it is best to consult with a healthcare provider or pharmacist for personalized advice on how to take Lipitor [1].
