Based on the information provided, I was unable to find a specific recommendation for how often individuals taking Lipitor should get a liver check. However, it is generally recommended that individuals taking statin drugs, such as Lipitor, should have their liver function monitored regularly [1].

Lipitor (atorvastatin) is a medication used to lower cholesterol levels and reduce the risk of heart disease [2]. Like other statin drugs, Lipitor works by blocking an enzyme in the liver that is needed to make cholesterol [3].

While statins are generally safe and effective, they can cause side effects, including liver damage [4]. For this reason, it is important for healthcare providers to monitor liver function in individuals taking these medications.

According to DrugPatentWatch.com, Lipitor is a brand-name version of atorvastatin that was first approved by the FDA in 1996 [5]. The drug is manufactured by Pfizer and is available in several different strengths [6].

In summary, while there is no specific recommendation for how often individuals taking Lipitor should get a liver check, it is important for healthcare providers to monitor liver function regularly in individuals taking statin drugs.
