Anaemia in Pregnancy (Iron/Folate/B12)
Admission & discharge
Admission/discharge guidance checked 2026-10-18 against the linked sources. This is a clinical checklist for an individual decision, not an automatic discharge order.
When admission or continued hospital care is needed
- Admit active significant bleeding, cardiovascular compromise, syncope, severe symptoms or a need for urgent transfusion/close monitoring. Consider proximity to birth and access to definitive treatment.
When clinic, day care or home care may be suitable
- Stable confirmed deficiency can usually be treated with oral iron or a planned infusion service when appropriate. The Hb value must be interpreted with symptoms, gestation and cause.
Before going home
- No ongoing bleeding or physiological instability; the anaemia cause, treatment route and response plan are documented.
- After IV iron or transfusion, the required observation is complete and any reaction has been assessed. Do not discharge only because an infusion finished.
Discharge medicines and treatment changes
- Use a specific elemental-iron/folate prescription for confirmed IDA; assess B12/folate or other causes when indicated. Avoid duplicate oral/IV/OTC iron.
- Postpartum anaemia treatment differs from a preventive supplement; specify what continues and when it is reviewed.
Medicine doses — use only when indicated
Use the medicines selected for this patient. Listed alternatives are not instructions to prescribe all of them together. Confirm the actual remaining course, pregnancy/postnatal context and monitoring plan.
For confirmed antenatal iron-deficiency anaemia.
- Indication: Confirmed iron deficiency with anaemia; exclude haemoglobinopathy/other causes and assess urgency
- Daily WHO treatment and prevention doses are different. Alternate-day strategies need an explicit alternative prescription and response review.
- Hb response after 2–4 weeks, adherence, GI effects and evidence of iron deficiency; investigate non-response and consider IV replacement when indicated
For diagnosed postpartum iron-deficiency anaemia after the acute cause is controlled.
- Indication: Diagnosed postpartum iron-deficiency anaemia after haemorrhage is controlled and outpatient oral treatment is suitable
- The WHO 2025 supportive-care recommendation supplies the postpartum dose/endpoint. Preparation and response monitoring reuse the checked oral-iron reference; breastfeeding is compatible with indicated maternal supplementation.
- Arrange Hb response review after 2–4 weeks, tolerance and adherence; investigate non-response or ongoing bleeding and reassess the replacement route.
- Review the cause of anaemia and any coexisting B12/folate deficiency or haemoglobinopathy.
Tests, pending results and their reviewer
- Record Hb/indices and relevant deficiency investigations; repeat Hb after about 2–4 weeks of oral treatment and investigate an inadequate response.
Home care and counselling
- Discuss administration, side effects, adherence, diet and how to access the next test or infusion.
Follow-up: when and what to review
| When | Action / responsible service |
|---|---|
2–4 weeks after starting oral treatment | Check Hb response, tolerance and adherence; reassess the diagnosis if response is inadequate. |
Before birth / after major blood loss | Reassess urgency, replacement progress and any specialist/transfusion plan. |
Return urgently
- New chest pain, breathlessness at rest, fainting, rapid deterioration or recurrent heavy bleeding requires urgent assessment.
Treatment
① Immediate stabilization — first minutes
- Symptomatic severe anaemia near birth: transfuse (target ~8-9 pre-delivery context) + treat cause simultaneously
③ First-line treatment & drug regimens
- Confirmed iron deficiency with anaemia; exclude haemoglobinopathy/other causes and assess urgency
- Daily WHO treatment and prevention doses are different. Alternate-day strategies need an explicit alternative prescription and response review.
- Hb response after 2–4 weeks, adherence, GI effects and evidence of iron deficiency; investigate non-response and consider IV replacement when indicated
- Laboratory-confirmed iron deficiency when oral iron is ineffective/intolerable or faster replacement is indicated; assess trimester and infection
- Label total-need table: Hb <10 g/dL: 35–<70 kg 1500 mg, ≥70 kg 2000 mg. Hb 10–<14: 1000 mg and 1500 mg respectively. Hb ≥14: 500 mg. Below 35 kg: use the label weight-based calculation.
- A 60 kg patient with Hb 8 g/dL therefore needs 1500 mg TOTAL, split 1000 mg then 500 mg ≥7 days later; 1000 mg is not automatically the full deficit.
- Observe during and at least 30 min after infusion with anaphylaxis treatment available; monitor extravasation
- Hb reassessment no earlier than 4 weeks after final dose; phosphate for repeated/high-dose courses or symptoms
- Routine pregnancy supplementation, particularly high-anaemia-burden settings
- Start folic acid before conception where possible. High-risk neural-tube-defect prevention is a separate higher-dose folate prescription.
- Hb/anaemia screening, tolerance, adherence and additional risk of folate/B12 deficiency
Definitive treatment
Store repletion + cause correction (bleeding, diet, deworming per programme).
Monitoring
- Hb 2-4 wks after change
- Individualised transfusion thresholds
Response assessment
- >=1 g/dL per fortnight oral; symptom improvement
Treatment failure
- Non-response: adherence, blockers, occult loss, alternative dx -> switch IV
Second-line treatment
- IV pathway; haematology referral uncertainty
Rescue treatment
Cardiac-compromised: slow PRBC transfusion; equipped-unit birth planning.
Escalation
- Haemoglobinopathy pregnancies -> haematology co-care
⑮ Complications & their management
PPH amplification
Correct BEFORE birth - strongest modifiable PPH-death factor locally
PTB/LBW associations
Timely correction reduces risk
Post-treatment care
- Iron continues 3 months postpartum
- Family haemoglobinopathy screening
Diagnosis & assessment
- Hb <7 or cardiac symptoms -> transfusion consideration + IV iron
- Unresolved bleeding source stacking PPH risk
- Microcytosis with normal-high ferritin -> thalassaemia workup FIRST
Definition: WHO pregnancy anaemia <11.0 g/dL; severe <7.0.
Initial assessment
- CBC indices + smear
- Iron studies (ferritin +/- TSAT)
- B12/folate when macrocytic/mixed
- HPLC/electrophoresis where indicated
Investigations
| Test | Looking for |
|---|---|
Ferritin | <30 ng/mL supports absolute deficiency |
HPLC | Beta-thal trait / variants |
