Intentional ipecac poisoning: Munchausen syndrome by proxy.

The intentional poisoning of two children with ipecac by their mothers is described. Intractable vomiting and diarrhea were the initial symptoms in both patients. In addition, one patient had clinical and laboratory evidence of skeletal and cardiac myopathy. Both children were subjected to extensive and invasive diagnostic evaluations before the correct diagnosis of chronic ipecac poisoning was made. These cases illustrate the toxic effects of ipecac ingestion and serve to alert physicians to child abuse by ipecac poisoning.
