Desferrioxamine 💊
ℹ️ About
Always check the BNF link here 📖 for up-to-date prescribing advice.
- Desferrioxamine is a chelating agent used to treat iron and aluminium overload 🧲.
⚙️ Mode of Action
- Binds free iron (ferric Fe³⁺) and aluminium to form stable, water-soluble complexes (ferrioxamine, aluminoxamine).
- These complexes are excreted in urine and bile, reducing toxic metal accumulation.
💊 Indications & Dose
| Indication | Dose / Frequency | Route |
|---|---|---|
| Iron & aluminium toxicity | 15 mg/kg/h (max 80 mg/kg/24 h) | IV infusion |
| Chronic iron overload (e.g. transfusion-dependent thalassaemia) | 20–40 mg/kg/day, up to 5–7 days per week | SC infusion (over 8–12 h) |
💡 Chelated iron produces reddish urine (“vin rosé” colour) - useful clinical clue.
⚠️ Interactions
- See BNF. Use with caution with vitamin C (high doses may ↑ risk of cardiac dysfunction when combined).
🔎 Cautions
- Rapid infusion may cause hypotension and collapse.
- Monitor for visual and auditory disturbances with prolonged use 👀👂.
- Infection risk: desferrioxamine predisposes to Yersinia and Mucormycosis 🦠.
🚫 Contraindications
- Severe renal impairment (drug excreted renally).
- Hypersensitivity to desferrioxamine.
❗ Side Effects
- Local pain at IM/SC injection site 💉.
- Hypotension if infused too rapidly.
- Acute lung injury / ARDS (rare) 🫁.
- GI upset: abdominal pain, nausea 🤢.
- Red urine due to ferrioxamine complex.
- Risk of opportunistic infections (Yersinia, mucormycosis).
