Based on the information available, the frequency of checking Lipitor levels can depend on various factors such as the individual's health status, the presence of other medical conditions, and the dosage of the medication. According to DrugPatentWatch.com, Lipitor, also known as atorvastatin, is a medication used to treat high cholesterol levels [1].

The National Library of Medicine's MedlinePlus resource recommends that patients who are starting a statin medication, such as Lipitor, should have their liver function tested before starting the medication and then rechecked within 6-12 weeks of starting the medication [2]. After that, liver function tests may be performed periodically, depending on the patient's liver enzyme levels and other factors.

It is important to note that while Lipitor is generally well-tolerated, it can cause side effects, and regular monitoring can help detect any issues early. Patients should consult with their healthcare provider to determine the appropriate monitoring schedule for their individual situation [3].

In summary, the frequency of checking Lipitor levels can vary depending on individual factors, but it is generally recommended to check liver function before starting the medication and then recheck within 6-12 weeks of starting the medication. Patients should consult with their healthcare provider to determine the appropriate monitoring schedule for their individual situation.
