Oral: Iron is absorbed in the duodenum and upper jejunum; in persons with normal iron stores 10% of an oral dose is absorbed; this is increased to 20% to 30% in persons with inadequate iron stores; food and achlorhydria will decrease absorption
Urine, sweat, sloughing of intestinal mucosa, and by menses
Onset of Action
Hematologic response: Red blood cells form within 3 to 10 days; similar onset as parenteral iron salts; Maximum effect: Peak reticulocytosis occurs in 5 to 10 days, and hemoglobin values increase within 2 to 4 weeks
Use: Labeled Indications
Iron-deficiency anemia: Management (prevention and treatment) of iron-deficiency anemia
Known hypersensitivity to polysaccharide-iron complex or any component of the formulations; hemochromatosis; hemosiderosis
Documentation of allergenic cross-reactivity for other iron-containing products is limited. However, because of similarities in chemical structure and/or pharmacologic actions, the possibility of cross-sensitivity cannot be ruled out with certainty.
Note: Immediate release oral iron products are preferred for treatment of iron-deficiency anemia; enteric coated and slow/sustained release preparations are not desired due to poor absorption (Hershko 2014; Liu 2012). Dose expressed in terms of elemental iron.
Iron-deficiency anemia: Oral: 50 to 200 mg elemental iron/day (Liu 2012; Schrier 2019). Note: Alternate-day dosing (eg, every other day or Monday, Wednesday, Friday) has been shown to result in greater absorption of iron; some experts recommend this dosing schedule in patients who can maintain adherence (Schrier 2019; Stoffel 2017).
Refer to adult dosing.
Note: Dosages are expressed in terms of elemental iron.
Iron deficiency anemia; prevention: Oral:
Infants ≥4 months (receiving human milk as only nutritional source or >50% as source of nutrition without iron fortified food): 1 mg/kg/day (AAP [Baker 2010]); Note: In healthy, term infants, AAP does not recommend routine additional supplementation of iron be considered until at least 4 to 6 months of age if breastfed (full or partial) (AAP [Baker 2010]; Schanler 2011)
Infants ≥6 months and Children <2 years in areas where anemia prevalence is >40%: 10 to 12.5 mg daily for 3 consecutive months in a year (WHO 2016b)

Alpha-Lipoic Acid: Iron Preparations may decrease the absorption of Alpha-Lipoic Acid. Alpha-Lipoic Acid may decrease the absorption of Iron Preparations. Management: Separate administration of alpha-lipoic acid from that of any iron-containing compounds by several hours. If alpha-lipoic acid is given 30 minutes before breakfast, then administer oral iron-containing products at lunch or dinner. Consider therapy modification

If coadministered with antacids, monitor for decreased therapeutic effects of iron preparations. Consider therapy modification
Baloxavir Marboxil: Polyvalent Cation Containing Products may decrease the serum concentration of Baloxavir Marboxil. Avoid combination
Bictegravir: Iron Preparations may decrease the serum concentration of Bictegravir.

Management: Do not administer intravenous (IV) ferric hydroxide polymaltose complex with other oral iron preparations. Therapy with oral iron preparations should begin 1 week after the last dose of IV ferric hydroxide polymaltose complex. Consider therapy modification
Histamine H2 Receptor Antagonists: May decrease the absorption of Iron Preparations. Monitor therapy
Levodopa: Iron Preparations may decrease the serum concentration of Levodopa. Only applies to oral iron preparations. Management: Consider separating doses of the agents by 2 or more hours to minimize the effects of this interaction. Monitor for decreased therapeutic effects of levodopa during concomitant therapy, particularly if doses cannot be separated. Consider therapy modification
Levothyroxine: Iron Preparations may decrease the serum concentration of Levothyroxine. Management: Separate oral administration of iron preparations and levothyroxine by at least 4 hours. Separation of doses is not required with parenterally administered iron preparations or levothyroxine. Consider therapy modification

Quinolones: Iron Preparations may decrease the serum concentration of Quinolones. Management: Give oral quinolones at least several hours before (4 h for moxi- and sparfloxacin, 2 h for others) or after (8 h for moxi-, 6 h for cipro/dela-, 4 h for lome-, 3 h for gemi-, and 2 h for enox-, levo-, nor-, oflox-, peflox, or nalidixic acid) oral iron. Exceptions: LevoFLOXacin (Oral Inhalation). Consider therapy modification
Raltegravir: Polyvalent Cation Containing Products may decrease the serum concentration of Raltegravir. Management: Administer raltegravir 2 hours before or 6 hours after administration of the polyvalent cations. Dose separation may not adequately minimize the significance of this interaction. Consider therapy modification
Tetracyclines: May decrease the absorption of Iron Preparations. Iron Preparations may decrease the serum concentration of Tetracyclines. Management: Avoid this combination if possible. Administer oral iron preparations at least 2 hours before, or 4 hours after, the dose of the oral tetracycline derivative. Monitor for decreased therapeutic effect of oral tetracycline derivatives. Exceptions: Eravacycline; Tigecycline. Consider therapy modification
Trientine: Polyvalent Cation Containing Products may decrease the serum concentration of Trientine. Management: Avoid concomitant administration of trientine and oral products that contain polyvalent cations. If oral iron supplements are required, separate the administration by 2 hours. If other oral polyvalent cations are needed, separate administration by 1 hour. Consider therapy modification
>10%: Gastrointestinal: Constipation, darkening of stools, epigastric pain, gastrointestinal irritation, nausea, stomach cramps, vomiting
1% to 10%:
Gastrointestinal: Dental discoloration, diarrhea, heartburn
Genitourinary: Urine discoloration
<1%, postmarketing, and/or case reports: Local irritation
Concerns related to adverse effects:
• Stool discoloration: Oral iron preparations commonly cause dark or black stools; patients should be informed of the effect.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information. May interfere with absorption of antibiotics.
• Pediatric: Accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under 6 years of age. Keep this product out of the reach of children. In case of accidental overdose call the poison control center immediately.
Dosage form specific issues:
• Oral iron formulations: Immediate release oral iron products are preferred for treatment of iron deficiency anemia; enteric coated and slow/sustained release preparations are not desired due to poor absorption (Hershko 2014; Liu 2012).
• Appropriate use: Investigate type of anemia and potential underlying causes (eg, recurrent blood loss) prior to initiating iron supplementation.
• Excipient: Some formulations may contain tartrazine, which is associated with allergic-type reactions. Although rare, hypersensitivity is more frequently seen in individuals with aspirin allergy.
Maternal iron requirements increase during pregnancy. Adequate iron concentrations to the fetus can be maintained regardless of maternal iron status, except in severe cases of anemia (IOM 2001). Untreated iron deficiency and iron deficiency anemia (IDA) in a pregnant female may be associated with adverse events, including low birth weight, preterm birth, or increased perinatal mortality (ACOG 95 2008; BSH [Pavord 2020]; IOM 2001).
In general, treatment of iron deficiency or IDA in pregnancy is the same as in nonpregnant females (USPSTF [Siu 2015]). Ferrous salts are preferred for oral management of IDA in pregnancy (BSH [Pavord 2020]). Iron supplementation is recommended for 3 months once hemoglobin is within the normal range, and for at least 6 months postpartum to replenish maternal iron stores (BSH [Pavord 2020]; FIGO 2019). The majority of studies note iron therapy improves maternal hematologic parameters; however, information related to clinical outcomes in the mother and neonate is limited (FIGO 2019; USPSTF [Siu 2015]). Oral preparations are generally sufficient; however, parenteral iron therapy may be used in females who cannot tolerate or will not take oral iron, in cases of severe iron deficiency, or when malabsorption is present (ACOG 95 2008; BSH [Pavord 2020]). Enteric-coated and slow/sustained-release preparations may be less effective and use should be avoided (ACOG 95 2008; BSH [Pavord 2019]).
