Junel Fe 24
Junel Fe 24
Generic Name
Junel Fe 24
Mechanism
- Reduces iron deficiency by supplying elemental iron that is absorbed in the duodenum.
- Fe³⁺ is reduced to Fe²⁺ by duodenal ferric reductases (steap3), enabling transport through the divalent metal transporter‑1 (DMT‑1) into enterocytes.
- Inside enterocytes, iron is stored as ferritin or secreted into circulation via ferroportin, bound to transferrin for delivery to erythroid precursors.
- The resulting increase in serum iron supports hemoglobin synthesis and RBC maturation.

Pharmacokinetics
- Absorption: ~2‑5 % of oral dose reaches systemic circulation; peak plasma levels within *1–2 h* after ingestion.
- Distribution: Binds transferrin; stored mainly in bone marrow, spleen, and liver.
- Metabolism/Elimination: Little hepatic metabolism; iron is incorporated into hemoglobin or ferritin; excess is excreted via the gut lumen. Elimination half‑life ≈ *30 min* for absorbed iron, but iron stores persist and are metabolically turned over over weeks–months.
- Factors affecting absorption:
- Inhibition by calcium, phytates, polyphenols, and high‑fat meals.
- Enhancement by vitamin C (ascorbic acid) and citrate.

Indications
- Prevention of iron‑deficiency anemia in at-risk populations (e.g., menstruating women, pregnancy, infancy, vegetarians).
- Maintenance therapy for patients with mild iron‑deficiency anemia when higher elemental doses are not required.
- Adjunct in dietary iron supplementation for chronic disease or malabsorption when low-dose iron is preferred to reduce gastrointestinal toxicity.

Contraindications
Contraindications
• Known hemochromatosis or iron overload disorder.
• Iron‑related hypersensitivity (e.g., allergic reaction to ferrous compounds).
• Acute hemolysis or hemoglobinopathies requiring high-dose iron replacement.
Warnings
• Gastrointestinal irritation (nausea, constipation) – take with a small amount of liquid or food.
• Black or tarry stools – benign side effect but may conceal GI bleeding; evaluate if persistent or accompanied by melena.
• Oxidative stress potential in patients with chronic inflammatory disease; avoid excessive dosing.
• Pregnancy: safe at recommended doses; high doses may increase oxidative stress.

Dosing
- Adult & adolescent: 1 tablet *once daily*, preferably in the morning with water.
- Infants 6–12 mo.: 1 tablet *every 12 h* (if physician prescribes a low‑dose formulation).
- Patients with iron‑deficiency anemia requiring higher elemental iron: 24 mg per tablet is generally insufficient; consider higher‑dose preparations (e.g., 100–200 mg elemental iron) under supervision.
- Take with vitamin C to enhance absorption; avoid concurrent calcium‑rich foods or supplements at the same time.
- Chewable tablets (if available) can improve taste and tolerance in children.

Adverse Effects
Common (≥10 %)
• Gastrointestinal: nausea, abdominal discomfort, constipation, diarrhea.
• Darkened stools.
• Headache, mild dizziness.
Serious (rare)
• Severe GI bleeding or ulceration (especially in patients with peptic ulcer disease).
• Hypersensitivity reactions: rash, angioedema.
• Hemolysis in G6PD deficiency if high‑dose formulations are mistakenly taken.

Monitoring
| Parameter | Frequency | Rationale |
| Hemoglobin/Hematocrit | Baseline, 2–4 wk, then 6 wk | Assess efficacy, dose adequacy |
| Serum ferritin | Baseline, 3 mo | Estimate iron stores |
| Transferrin Saturation | Baseline, 3 mo | Evaluate iron mobilization |
| Serum iron | Optional | Monitor absorption & overload |
| Liver enzymes | Baseline for patients with liver disease | Iron can stimulate oxidative stress |
| Clinical assessment | Each clinic visit | GI tolerance, compliance |

Clinical Pearls
- Vitamin C synergy: Combining 50 mg vitamin C with Junel Fe 24 can boost absorption up to 50 % – ideal for patients with marginal compliance or those eating a calcium‑rich diet.
- Timing matters: Taking the tablet *30 min before breakfast* can improve tolerability while avoiding interaction with iron‑blocking foods.
- Steady dose: A low‑dose daily regime (24 mg) reduces GI adverse events compared with intermittent high‑dose protocols, making it a preferable choice for maintenance therapy.
- Taste & compliance: If the tablet’s metallic taste is problematic, administer with a small amount of juice or as chewable (if available) to enhance adherence.
- Screen for hypersensitivity: Prior to therapy, review patient history for reactions to oral iron formulations; if uncertain, perform a skin test before initiating therapy in high‑risk individuals.

• Key Takeaway – Junel Fe 24 is a low‑dose, well-tolerated oral iron supplement suited for preventive use and mild iron‑deficiency management. Optimize absorption with vitamin C, avoid calcium‑rich meals, and monitor hematologic indices to ensure effective and safe therapy.
