Drug Monograph
USE IF: Iron deficiency anemia, iron deficiency states, prevention in selected high-risk patients
AVOID IF: Iron overload states, anemia without confirmed iron deficiency
Ferrous sulfate
Oral iron (heme synthesis support) for iron repletion
Indication
Iron deficiency anemia • Iron deficiency states
INDICATIONS (CORE USE)
- Iron deficiency anemia - Iron deficiency without anemia (selected)
ADULT DOSE (STANDARD)
Typically 100-200 mg elemental iron daily Use divided or alternate-day dosing depending on tolerance
MAX DOSE
Avoid excessive dosing; absorption plateaus and side effects increase
Route
PO
PEDIATRIC DOSE
Protocol-based
Must-not-miss safety points
Major warning
- Do NOT treat anemia without confirming iron deficiency - Poor absorption reduces effectiveness (food, PPIs, calcium) - GI side effects are a major cause of non-adherence - Continue treatment after hemoglobin normalizes to replenish iron stores
INDICATION: Iron deficiency anemia • Iron deficiency states
Primary
Secondary
STANDARD (ADULT PO)
Elemental iron dosing preferred (not just tablet strength); daily or alternate-day regimens based on tolerance
ADULT DOSE
STANDARD (ADULT): - Typically 100-200 mg elemental iron daily - Daily or alternate-day dosing depending on tolerance
PEDIATRIC DOSE
Protocol-based
MAX DOSE
Avoid excessive dosing; limited additional absorption and higher GI adverse effects
Practical Note
- Absorption is better on an empty stomach, but GI intolerance may increase - Alternate-day dosing may improve tolerance and absorption - Adjust regimen based on response and adherence
Clinical warnings
Adverse effects
Pediatrics
Protocol-based
Pregnancy
Pregnancy: Commonly required supplementation for iron deficiency risk or confirmed deficiency
Lactation
Compatible in usual oral replacement dosing; monitor maternal tolerance and adherence.
Renal impairment
Protocol-based adjustment and monitoring in chronic kidney disease pathways.
Hepatic impairment
No routine hepatic dose adjustment; monitor for alternative causes of anemia if response is poor.
Elderly
Monitor GI tolerance, adherence, and causes of occult blood loss.
- Oral dosing - Take on an empty stomach if tolerated - Take with food when GI intolerance limits adherence - Separate from calcium, antacids, and other interacting medications
Clinical Picture
GI toxicity (nausea, vomiting, abdominal pain); severe overdose can cause systemic toxicity, especially in children
Immediate Actions
Urgent evaluation for any suspected significant overdose; involve poison center/toxicology early
Antidote
Chelation (e.g., deferoxamine) in severe iron toxicity
Decontamination
Per poison center or toxicology guidance; do not delay escalation in symptomatic patients
Escalation
Escalate urgently for pediatric ingestion, systemic symptoms, metabolic acidosis, shock, or altered mental status
