Gastrointestinal disturbances, such as diarrhea, nausea, abdominal pain, and vomiting, are very common because<unk>  is a motilin agonist. Because of this,<unk>  tends not to be prescribed as a first-line drug. More serious side effects include arrhythmia with prolonged QT intervals, including torsades de pointes, and reversible deafness. Allergic reactions range from urticaria to anaphylaxis. Cholestasis, Stevens–Johnson syndrome, and toxic epidermal necrolysis are some other rare side effects that may occur. Studies have shown evidence both for and against the association of pyloric stenosis and exposure to<unk>  prenatally and postnatally. Exposure to<unk>  (especially long courses at antimicrobial doses, and also through breastfeeding) has been linked to an increased probability of pyloric stenosis in young infants.<unk>  used for feeding intolerance in young infants has not been associated with hypertrophic pyloric stenosis.<unk>  estolate has been associated with reversible hepatotoxicity in pregnant women in the form of elevated serum glutamic-oxaloacetic transaminase and is not recommended during pregnancy. Some evidence suggests similar hepatotoxicity in other populations. It can also affect the central nervous system, causing psychotic reactions, nightmares, and night sweats.
