The timing of taking Lipitor after exercise is not mentioned in the provided sources. Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the blood [1]. It is typically taken once a day, with or without food, and at the same time each day [3]. According to a study published in the National Center for Biotechnology Information, taking statins, including Lipitor, after exercise does not appear to have any adverse effects on muscle function or damage [2]. However, it is always best to consult with a healthcare provider regarding the timing and dosage of medication. Additionally, statins are usually prescribed for long-term use, and stopping the medication abruptly can have negative consequences, including an increased risk of heart attack and stroke [3]. Therefore, it is important to follow the healthcare provider's instructions regarding the use of Lipitor.
