Venofer (Iron Sucrose) Written Order for Iron Deficiency Anemia
For adult patients with iron deficiency anemia, order Venofer 200 mg IV over 15 minutes (or 2-5 minutes undiluted), administered 5 times over a 14-day period for a total dose of 1000 mg. 1
Standard Dosing Regimens by Clinical Context
Non-Dialysis Dependent Patients (Most Common Outpatient IDA)
- Venofer 200 mg IV diluted in maximum 100 mL 0.9% NaCl over 15 minutes
- Administer on 5 separate occasions over 14 days (total 1000 mg)
- Alternative: 500 mg diluted in 250 mL 0.9% NaCl over 3.5-4 hours on Day 1 and Day 14 (limited experience) 1
Hemodialysis Dependent Patients
- Venofer 100 mg IV per dialysis session
- Give undiluted over 2-5 minutes OR diluted in 100 mL 0.9% NaCl over 15 minutes
- Administer early in dialysis session (first hour)
- Total course: 1000 mg (10 consecutive sessions) 1
Peritoneal Dialysis Dependent Patients
- 300 mg IV over 1.5 hours on Day 1
- 300 mg IV over 1.5 hours on Day 14
- 400 mg IV over 2.5 hours on Day 28
- Dilute in maximum 250 mL 0.9% NaCl 1
Pediatric Dosing (≥2 Years)
- 0.5 mg/kg IV (maximum 100 mg per dose)
- Hemodialysis: every 2 weeks for 12 weeks
- Non-dialysis/peritoneal dialysis on EPO: every 4 weeks for 12 weeks
- Give undiluted over 5 minutes OR diluted to 1-2 mg/mL in 0.9% NaCl over 5-60 minutes
- Never dilute below 1 mg/mL 1
Critical Safety Requirements
Test dose is NOT required for iron sucrose per FDA labeling, unlike iron dextran 2. However, consider 25 mg slow IV push test dose at physician discretion if patient has:
- Prior sensitivity to IV iron dextran
- Multiple drug allergies 2
Mandatory Monitoring and Precautions
- Observe patient for minimum 30 minutes post-infusion until clinically stable 1
- Have resuscitation equipment immediately available 1
- Do not administer if active infection present 2
- Monitor for hypotension during infusion (rate-related) 1
Contraindications
Laboratory Monitoring
Before treatment:
- Hemoglobin, hematocrit
- Serum ferritin
- Transferrin saturation (TSAT)
After treatment:
- Wait minimum 48 hours before checking serum iron/TSAT (values increase rapidly post-infusion) 1
- Recheck hemoglobin at 4-6 weeks
- Monitor ferritin to assess iron stores 3
Key Advantages Over Other Formulations
The 2021 KDIGO guidelines 4 and 2011 Gut guidelines 3 demonstrate that iron sucrose has maximum single dose of 200 mg (lower than newer formulations like ferric carboxymaltose at 1000 mg), requiring multiple visits but with established safety profile. The 2024 expert consensus 5 notes iron sucrose is a "salt" formulation that releases more labile iron at higher doses, explaining the 200 mg limit.
Iron sucrose advantages:
- No test dose required (unlike iron dextran) 2
- Lower hypersensitivity risk than high-molecular-weight iron dextran 3
- Extensive pediatric safety data (approved ≥2 years in US) 6, 1
- Rapid bolus administration possible (2-5 minutes for 200 mg) 3
Common Pitfalls to Avoid
- Do NOT exceed 200 mg per dose in adults (300 mg not recommended) 2
- Do NOT dilute below 1 mg/mL concentration in pediatrics 1
- Do NOT check iron studies within 48 hours of administration 1
- Do NOT give if patient has active infection 2
- Do NOT assume test dose is required (this is iron dextran requirement only) 2
Expected Adverse Events
Most common (generally mild):
- Hypotension, hypertension
- Nausea, vomiting, diarrhea
- Headache, dizziness
- Pain at injection site 2
Serious hypersensitivity reactions are rare but can occur; most reactions occur within 30 minutes of completion 1. Recent 2025 research 7 in 100 female patients showed no serious adverse events with 200 mg twice weekly dosing.
Sample Written Order
