Presentation
- 500mg vial
- 2000mg vial
Role
- Management of severe iron toxicity evidenced by GI haemorrhage, severe hypotension, coma, or metabolic acidosis and serum iron concentration >60 micromol/L (or unavailable).
- Management of patients with iron poisoning and an iron concentration >90 micromol/L at 6h post ingestion.
All cases should be discussed with a clinical toxicologist through the local toxicology service or Poisons Information Centre 13 11 26.
Dose
Give 15mg/kg/hr as an IV infusion until serum iron concentration falls below 60 micromol/L. Therapy is typically needed for 6 hours. The dose should be reduced by 50% in renal impairment (eGFR < 50mL/min).
Stocking recommendations
Tertiary centre | Regional centre | Rural centre | Remote centre |
---|---|---|---|
20 x 500mg vials or 5 x 2g vials |
20 x 500mg vials or 5 x 2g vials |
0 – 10 x 500mg vials or 0 – 2 x 2g vials | 0 vials |
Rationale
Iron chelation is uncommonly required. 10g supply will provide a full treatment course for a 100kg person. For rural centres, 4-5g will be sufficient to initiate therapy in anticipation of retrieval to a regional or tertiary centre. However, given this is an uncommon poisoning stocking in a rural centre is not essential.
Precautions
- Infusion-related hypotension is common, ensure adequate hydration before commencing infusion.
- Urine will often change to a vin rose colour following desferrioxamine.
