Lipitor is a brand name for the drug atorvastatin, which is a statin medication used to lower cholesterol levels in the body [1]. Statins are generally safe and well-tolerated, but like all medications, they can have side effects, including the potential for overdose [2].

According to the Mayo Clinic, an overdose of Lipitor or any other statin medication can cause symptoms such as muscle pain, weakness, and tenderness, as well as liver damage and kidney failure in severe cases [2]. However, the long-term effects of a Lipitor overdose are not clear.

A study published in Circulation Research in 2018 found that high doses of atorvastatin (not necessarily an overdose) can lead to the accumulation of a protein called p62 in the liver, which can cause liver damage over time [3]. However, it is important to note that this study was conducted on mice and not humans, so the results may not necessarily apply to humans.

In general, it is important to take medications as prescribed and to seek medical attention immediately if an overdose is suspected. It is also important to talk to a healthcare provider about any concerns regarding the potential long-term effects of a medication overdose.
