Although CCB ingestion has no race predilection among young children, racial trends mirror suicide attempt statistics among adolescents. In young children, a male predilection for CCB toxicity is observed. In adolescence, the sex predilection again mirrors suicide attempt statistics, with more females than males ingesting calcium channel blocker agents.

CCB ingestions show a bimodal distribution in the pediatric age range. Infants and toddlers often unintentionally ingest tablets that they mistake for food or candy. Teenagers ingest CCBs as a suicide gesture.
