Sold by Pfizer, lipid-lowering medicine Lipitor is the top-selling prescription drug in the world. Lipitor lowers blood cholesterol, stabilizes plaque, and forbids strokes through anti-inflammatory mechanisms. It inhibits HMG-CoA reductase enzyme that helps in the production of cholesterol in humans. However, the drug can cause several side effects, including devastating effects on human muscle and nerve cells. Memory loss, fatigue, myopathy, insomnia, chest pain, urinary tract infection, myalgia, and severe allergic reaction are among the serious side effects of Lipitor.
A feature story entitled "Life After Lipitor" published by Californian newspaperTahoe World on January 27, 2004 highlighted the plight of a Lipitor user from Tahoe City. Doug Peterson, the victim, developed severe neuromuscular problems within two years of taking Lipitor. He experienced lack of muscular coordination, loss of effective motor skills, balancing problems, and trouble talking. His health began improving after he stopped taking the drug. It followed by several reports in medical journals and websites highlighting numerous adverse side effects of the drug. Since then it has been linked to multiple sclerosis, memory loss, motor neuropathy, vertigo, disorientation, and stiffness in neck and calf muscles as corroborated by the users of the drug.

A class action lawsuit was filed against Pfizer in June 2006 in New York State Supreme Court alleging failure to inform doctors and patients about serious side effects linked to Lipitor. It claimed that the drug caused memory loss and debilitating muscle and nerve problems to several users in New York and Atlanta. One of the plaintiffs, 60-year-old Atlanta man Charles M. Wilson, had complained that he continued suffering balancing problems, memory loss, and fatigue even three years after giving up Lipitor. Another lawsuit by 47-year-old New Yorker Michael Mazzariello alleged that he incurred debilitating damage to muscle cells and loss of memory after using cholesterol-lowering drugs, such as Lipitor. The complainants were of the view that Pfizer promoted the drug as safe and with minimal risks in its ads while doctors and patients came to know about its more dangerous side effects after using it.
