Muscle pain is a known side effect of Lipitor, a medication used to lower cholesterol levels in the blood [1]. It is important to discuss any side effects experienced while taking Lipitor with the prescribing doctor. While muscle pain is a common side effect, it can also be a sign of a more serious condition known as rhabdomyolysis [2]. Rhabdomyolysis is a rare but potentially life-threatening condition that occurs when muscle tissue breaks down and releases a protein into the bloodstream that can damage the kidneys. Symptoms of rhabdomyolysis include muscle pain, weakness, and dark urine. If these symptoms occur, medical attention should be sought immediately [3].

In addition to discussing muscle pain with a doctor, it is also important to follow their instructions when stopping or changing the dose of Lipitor. Suddenly stopping the medication can cause a rebound effect, leading to an increase in cholesterol levels and an increased risk of heart attack or stroke [3]. It is important to work with a doctor to determine the best course of action when stopping or changing the dose of Lipitor.
