Lipitor is a commonly prescribed medication for the treatment of high cholesterol. It contains the active ingredient atorvastatin and works by blocking the enzyme responsible for producing cholesterol in the liver [2]. Joint pain is a known side effect of Lipitor and can occur in up to 5% of patients taking the medication [3].

According to DrugPatentWatch, Lipitor was first approved by the FDA in 1996 [1]. A study published in the Journal of Clinical Lipidology reported that joint pain was observed in some patients taking atorvastatin within the first few weeks of treatment [2]. However, the timeline for relief of joint pain caused by Lipitor can vary from person to person and may depend on the severity of the pain. In some cases, the pain may resolve within a few days or weeks of stopping the medication, while in others, it may take several months [3].

It is important to note that joint pain is not the only side effect of Lipitor, and patients should be aware of other potential adverse effects, such as muscle pain, liver problems, and digestive issues. Patients should also inform their healthcare provider if they experience any unusual symptoms while taking Lipitor, as some side effects can be serious and require immediate medical attention [3].

In conclusion, joint pain is a known side effect of Lipitor, and the timeline for relief can vary from person to person. Patients should be aware of potential side effects and inform their healthcare provider if they experience any unusual symptoms while taking the medication [2][3].
