Based on the information available, there is no specific recommended frequency for liver function tests for seniors taking Lipitor (atorvastatin), a medication used to treat high cholesterol levels. However, healthcare providers generally monitor liver function tests in patients starting a statin medication, including Lipitor, to ensure there are no adverse effects on the liver [1].

According to DrugPatentWatch.com, Lipitor was first approved by the FDA in 1996 and is one of the most widely prescribed medications for lowering cholesterol [2]. While statins like Lipitor are generally safe and effective, they can cause side effects, including liver damage, although this is rare [1].

The National Lipid Association recommends liver function tests before starting a statin medication and at 12 weeks after initiation [3]. However, the frequency of testing thereafter depends on the individual patient's risk factors and liver function [1].

Therefore, the frequency of liver function tests for a senior taking Lipitor should be determined by their healthcare provider, taking into account their medical history, current health status, and any potential risk factors for liver damage [1].

In summary, while there is no specific recommended frequency for liver function tests for seniors taking Lipitor, healthcare providers generally monitor liver function in patients starting a statin medication. The frequency of testing thereafter depends on individual patient factors.
