Abstract

We report a young infant with diarrhoea and associated methaemoglobinaemia, who presented acutely with shock and cyanosis. The baby was subsequently diagnosed to have cow's milk protein intolerance. The clinical features, pathogenesis, aetiology and management of the condition were reviewed. We would like to highlight that methaemoglobinaemia is a medical emergency, and prompt treatment with methylene blue is life-saving and usually results in good outcome.
