Background
Most accidental paediatric drug ingestions involve doses that fall well below what would be considered a toxic ingestion. There are a handful of drugs and chemicals that are dangerous after relatively small paediatric ingestions involving 1 or 2 dose units of an available preparation or a mouthful. These agents demand a cautious approach to risk assessment.
