Based on the information provided, it is not explicitly stated whether liver side effects of Lipitor were explained. However, Lipitor, a statin medication used to treat high cholesterol, is known to have potential liver-related side effects [1].

According to the drug's official FDA-approved label, Lipitor can cause an increase in liver enzymes, which can be a sign of liver injury [2]. However, the label also states that "Lipitor is associated with increased transaminase levels" but "the incidence of transaminase elevations following therapy with Lipitor is not significantly different from that of other statins or placebo in clinical trials" [2].

It is important to note that Lipitor's label recommends liver enzyme tests before starting the medication and periodically thereafter [2]. If liver enzyme levels are significantly elevated, Lipitor should be discontinued [2].

In summary, while it is not clear from the information provided whether liver side effects of Lipitor were explicitly explained, the drug is known to have potential liver-related side effects, and the FDA-approved label recommends monitoring liver enzymes during treatment [1,2].
