Lipitor is a prescription medication used to lower cholesterol levels in the blood. It is a type of medication called a statin, which works by blocking an enzyme in the liver that produces cholesterol. According to Mayo Clinic [2], Lipitor should be taken once a day, at the same time every day. It can be taken with or without food. However, it is important to note that there is no specific recommendation regarding the timing of Lipitor in relation to exercise.

It is important to discuss any concerns about Lipitor with a healthcare provider. While Lipitor is generally well-tolerated, it can cause side effects such as muscle pain, weakness, and liver problems [2]. In some cases, a healthcare provider may recommend stopping Lipitor or switching to a different medication. However, it is important to continue taking Lipitor as directed until a healthcare provider advises otherwise [3].
