Neither amount ingested nor<unk>  level are known:
Adult dose
10 vials over 30 min; repeat dose if clinical response is inadequate
Peds dose
5 vials over 30 min; repeat dose if clinical response is inadequate
Amount ingested is known but<unk>  level is unknown
Calculate total body load (TBL)
TBL = Dose (in mg) ingested x 0.8
Calculate number of vials needed
Number of vials = TBL X 2 (round up to nearest whole number)
Steady state<unk>  level is known
Number of vials = (dig level (in ng/mL) X patient wt) / 100
Chronic toxicity without severe signs
Give half the recommended dose
Otherwise may unmask the condition for which the patient is taking<unk>
