At a glance

INDICATIONS (CORE USE)

- Folate deficiency - Megaloblastic anemia - Pregnancy (prevention of neural tube defects)

ADULT DOSE (STANDARD)

Deficiency: typically ~1 mg daily Pregnancy supplementation: lower prophylactic dosing per guideline Onset / duration: gradual hematologic response

MAX DOSE

Context-dependent; avoid unnecessary high dosing without indication

Route

PO (IV/IM rarely used in specific contexts)

PEDIATRIC DOSE

Protocol-based

Do not miss

Must-not-miss safety points

Major warning

- Can mask vitamin B12 deficiency → neurologic damage may progress - Do NOT treat anemia without evaluating cause - Over-supplementation without indication is unnecessary

Indications

INDICATION: Folate deficiency • Megaloblastic anemia • Pregnancy supplementation

Primary

  • Folate deficiency
  • Megaloblastic anemia

Secondary

  • Pregnancy supplementation
  • Increased demand states (selected)

Dosing

STANDARD (ADULT PO)

Deficiency: ~1 mg daily PO (typical replacement context)

ADULT DOSE

STANDARD (ADULT): - Deficiency: ~1 mg daily - Maintenance depends on cause and response

PEDIATRIC DOSE

Protocol-based

MAX DOSE

Context-dependent; avoid unnecessary high dosing without indication

Practical Note

- Always evaluate anemia cause before treatment - Continue until deficiency corrected and cause addressed

Warnings

Clinical warnings

  • Masking of B12 deficiency
  • Delayed diagnosis of underlying pathology

Adverse effects

  • Generally well tolerated
  • Rare hypersensitivity

Contraindications

  • Known hypersensitivity
  • Use caution if B12 deficiency not excluded

Drug interactions

  • Limited major interactions
  • Some antiepileptics may be affected — consult product labeling when relevant

Special populations

Pediatrics

Protocol-based

Pregnancy

Pregnancy: Routine supplementation recommended

Lactation

See product labeling and lactation references.

Renal impairment

See product labeling and local protocol for dose adjustment in renal impairment.

Hepatic impairment

See product labeling.

Elderly

Evaluate for B12 deficiency before treatment

Administration

- Oral dosing - Continue as clinically indicated

Monitoring

  • Monitor: - Hemoglobin / CBC response - Clinical improvement
  • Recheck: - After initiation - Ensure cause of deficiency addressed - If no response → reassess diagnosis (including B12 status); DO NOT continue blindly without a clear cause
  • Hold / reassess: - If diagnosis uncertain - If no response

Overdose / toxicity

Clinical Picture

Generally minimal toxicity

Immediate Actions

Supportive care

Antidote

None

Decontamination

Supportive care; poison center if clinically indicated

Escalation

Escalate per clinical pathway if alternative serious diagnosis suspected

Clinical pearls

Common mistakes, resistance logic, and bedside traps

High-Yield

  • Always rule out B12 deficiency before treating anemia

Clinical

  • Important in pregnancy for neural tube defect prevention

Safety

  • Most common error = treating anemia without diagnosis
