Could one of the most widely prescribed antibiotics amoxicillin/clavulanate “augmentin™” be a risk factor for autism?

A proposed mechanism whereby the production of clavulanate may yield high levels of urea/ammonia in the child is presented. Further an examination of this mechanism needs to be undertaken to determine if a subset of children are at risk for neurotoxicity from the use of clavulanic acid in pharmaceutical preparations.
