Most common side-effects are gastrointestinal, including diarrhea, nausea, abdominal pain and vomiting. Headache and disturbances in taste also occur. Less common side-effects include palpitations, blurred vision, and rashes. Prolonged QTc intervals may also be caused by<unk> . Rare but severe side-effects were initially reported in March 2006, involving damage to the liver. Three different incidents were reported: one case of temporary drug-induced hepatitis, one ending in a liver transplant, and one ending in death. In the United States, the FDA's Office of Epidemiology and Surveillance identified 12 cases of acute liver failure, resulting in four deaths, and an additional 23 cases of acute, serious liver injury, among 5.2 million patients taking<unk>  through April 2006. In 2010, a published report described the likely mechanism of action underlying not only the cases of liver failure but also cases of visual disturbances and exacerbations of myasthenia gravis. The study showed that a pyridine moiety that is part of the<unk>  molecule acts as an antagonist on cholinergic receptors located in the neuromuscular junction, the ciliary ganglion of the eye and the vagus nerve innervating the liver. Other macrolides, such as azithromycin and clarithromycin and the fluoroketolide, solithromycin, do not contain the pyridine moiety and do not antagonize these cholinergic receptors significantly.
