Are one or two dangerous? Quinine and quinidine exposure in toddlers.
Quinine and quinidine have been cited as drugs that may cause significant morbidity and mortality in toddlers who ingest one or two pills. The use of both of these drugs has declined in the United States since the 1980s. A review of the literature and Poison Control data reveals that large quinine and quinidine ingestions, although rare in this country, may lead to severe toxicity and death related to cardiovascular and neurological effects in both children and adults. Although the majority of cases of quinine and quinidine toxicity in toddlers occur after ingestions of more than two pills, a single report each of severe toxicity after the equivalent of an ingestion of two pills or less by a toddler exists for both quinine and quinidine. Although the risk to the toddler exposed to one or two tablets seems to be small, triage to an Emergency Department is warranted after quinidine ingestion of any amount and after quinine ingestion that exceeds the age-appropriate therapeutic dose.
