Precautions & Cautions
Overdose Information
Overdose Symptoms:
- Acute iron overdose can lead to hypotension, shock, metabolic acidosis, liver damage, and coma.
- Chronic iron overload (hemochromatosis) can lead to organ damage (liver, heart, pancreas, joints) due to iron deposition.
What to Do:
Seek immediate medical attention. Management may include supportive care, chelation therapy (e.g., deferoxamine) in severe cases, and monitoring of iron levels and organ function. Call 1-800-222-1222 (Poison Control).
Drug Interactions
Major Interactions
- Oral iron preparations (concurrent administration may reduce absorption of oral iron)
Monitoring
Baseline Monitoring
Rationale: To assess severity of anemia and guide treatment.
Timing: Prior to initiation of therapy.
Rationale: To assess functional iron deficiency and guide treatment.
Timing: Prior to initiation of therapy.
Rationale: To assess iron stores and guide treatment.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline and monitor for hypersensitivity reactions or hypotension.
Timing: Prior to each infusion.
Routine Monitoring
Frequency: At least 1 month after the last dose of iron sucrose, or as clinically indicated.
Target: Individualized based on patient's condition and target Hb levels for CKD.
Action Threshold: Persistent low Hb or failure to respond may indicate need for further investigation or dose adjustment.
Frequency: At least 1 month after the last dose of iron sucrose, or as clinically indicated.
Target: Typically >20%
Action Threshold: TSAT <20% may indicate need for re-treatment.
Frequency: At least 1 month after the last dose of iron sucrose, or as clinically indicated.
Target: Typically >100 ng/mL (or >200 ng/mL for hemodialysis patients)
Action Threshold: Ferritin <100 ng/mL (or <200 ng/mL for HD) may indicate need for re-treatment.
Frequency: During and immediately after each infusion.
Target: Within patient's normal range.
Action Threshold: Significant drop in blood pressure or increase in heart rate may indicate hypersensitivity or hypotension, requiring immediate intervention.
Symptom Monitoring
- Signs of hypersensitivity/anaphylaxis (e.g., rash, itching, hives, shortness of breath, wheezing, chest tightness, swelling of face/lips/tongue/throat)
- Hypotension (dizziness, lightheadedness, fainting)
- Headache
- Nausea, vomiting, diarrhea, abdominal pain
- Muscle cramps, back pain, joint pain
- Peripheral edema
- Injection site reactions (e.g., pain, swelling, redness)
Special Patient Groups
Pregnancy
Venofer is used in pregnant women with iron deficiency anemia when oral iron is ineffective or not tolerated. Available data from postmarketing reports are insufficient to assess a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Animal reproduction studies show no evidence of harm to the fetus. Clinical considerations suggest that untreated iron deficiency anemia in pregnancy can lead to adverse maternal and fetal outcomes.
Trimester-Specific Risks:
Lactation
Limited data suggest that iron sucrose is excreted in human milk. However, the amount of iron transferred to breast milk is likely low and unlikely to cause adverse effects in a breastfed infant. The developmental and health benefits of breastfeeding should be considered along with the motherβs clinical need for Venofer and any potential adverse effects on the breastfed child from Venofer or from the underlying maternal condition.
Pediatric Use
Safety and efficacy have been established in pediatric patients 2 years of age and older with iron deficiency anemia and CKD. Dosing is weight-based. Safety and efficacy in pediatric patients less than 2 years of age have not been established.
Geriatric Use
No overall differences in safety or effectiveness were observed between elderly and younger patients. However, caution should be exercised when administering the drug to elderly patients, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Clinical Information
Clinical Pearls
- Administer slowly to minimize risk of hypotension and hypersensitivity reactions. For 100 mg dose, infuse over at least 15 minutes.
- Monitor patients for signs and symptoms of hypersensitivity reactions during and for at least 30 minutes following each Venofer infusion.
- Do not mix Venofer with other medications or add to parenteral nutrition solutions.
- Venofer should only be administered intravenously; do not administer intramuscularly or subcutaneously.
- Patients should be advised that iron sucrose may cause a temporary brown discoloration of the urine.
Alternative Therapies
- Oral iron supplements (e.g., ferrous sulfate, ferrous gluconate, ferrous fumarate)
- Other intravenous iron preparations (e.g., ferric carboxymaltose, ferumoxytol, iron dextran, ferric derisomaltose, ferric pyrophosphate citrate)
- Erythropoiesis-stimulating agents (ESAs) in combination with iron, for anemia of CKD.
