Dose

10mg/kg (up to 600mg) q8h PO for 5 days then q12h for 14 days.

Stocking recommendations

Rationale

Heavy metal poisoning requiring chelation is rare. Succimer is the preferred agent given its good safety profile. Administration is not time-critical and obtaining it, as required, from a tertiary centre is suggested.
