MULTIPLE VITAMINS INJECTION PEDIATRIC
Clinical safety rating: caution
Comprehensive clinical and safety monograph for MULTIPLE VITAMINS INJECTION PEDIATRIC (MULTIPLE VITAMINS INJECTION PEDIATRIC).
Multiple vitamins injection provides essential vitamins that act as cofactors and coenzymes in various metabolic pathways, supporting cellular metabolism, growth, and development.
| Metabolism | Metabolized in the liver; individual vitamins have specific metabolic pathways involving hepatic enzymes (e.g., hydrolysis, phosphorylation). |
| Excretion | Renal: variable, depending on water-soluble vitamins (e.g., ascorbic acid, B-complex) are primarily excreted unchanged in urine; fat-soluble vitamins (A, D, E, K) are excreted in feces via bile. Overall, ~50-70% of water-soluble vitamins are renally eliminated; fat-soluble vitamins are eliminated via biliary-fecal route (approx. 30-50% of dose). |
| Half-life | Highly variable per component: Thiamine (B1): ~10-20 min; Riboflavin (B2): ~66-84 min; Niacin (B3): ~45 min; Pyridoxine (B6): ~15-20 days; Ascorbic acid (C): ~16 days in adults, shorter in children (10-14 days); Retinol (A): ~2-3 weeks; Cholecalciferol (D3): ~2-3 months; Tocopherol (E): ~13-19 days; Phylloquinone (K1): ~2-3 hours. Clinical context: Half-life of individual vitamins determines dosing frequency; water-soluble vitamins require daily supplementation, while fat-soluble vitamins can accumulate. |
| Protein binding | Vitamin A: ~90-95% bound to retinol-binding protein; Vitamin D: ~85-90% bound to vitamin D-binding protein; Vitamin E: ~90-95% bound to lipoproteins; Vitamin K: ~90% bound to lipoproteins; B-complex: variable, e.g., thiamine ~90% bound to albumin, riboflavin ~60% bound to proteins; ascorbic acid: ~25% bound to albumin. Overall, fat-soluble vitamins >90% protein bound; water-soluble vitamins 25-90%. |
| Volume of Distribution | Highly variable: Water-soluble vitamins: small Vd, e.g., ascorbic acid ~0.4-0.6 L/kg, thiamine ~0.2-0.4 L/kg; fat-soluble vitamins: large Vd, e.g., retinol ~1.5-2.0 L/kg, cholecalciferol ~2.5-3.0 L/kg due to adipose storage. Clinical meaning: Wide distribution for fat-soluble vitamins indicates tissue sequestration; water-soluble vitamins distribute mainly in extracellular fluid. |
| Bioavailability | IV: 100%. IM: Variable: water-soluble vitamins ~70-90% (e.g., thiamine ~85%, ascorbic acid ~75%); fat-soluble vitamins ~50-70% (e.g., retinol ~60%, cholecalciferol ~55%) due to incomplete absorption from muscle. |
| Onset of Action | IV: Immediate (within minutes) for water-soluble vitamins; fat-soluble vitamins require hepatic conversion to active forms (hours to days). IM: Water-soluble vitamins: 15-30 minutes; fat-soluble vitamins: delayed onset, 24-72 hours due to absorption from injection site and hepatic activation. |
| Duration of Action | Water-soluble vitamins: short (hours to 1-2 days) due to rapid renal excretion; fat-soluble vitamins: prolonged (weeks to months) due to storage in liver and adipose tissue. Clinical notes: Daily repletion needed for water-soluble; fat-soluble vitamins can be dosed weekly or monthly. |
1 mL (single-dose vial) intravenously once daily for patients aged 11 years and older.
| Dosage form | INJECTABLE |
| Renal impairment | No specific adjustment recommended. Use with caution in severe renal impairment. |
| Liver impairment | No specific adjustment recommended. Use with caution in severe hepatic impairment. |
| Pediatric use | Infants and children <11 years: 0.5 mL intravenously once daily; Premature and low birth weight infants: 0.3 mL intravenously once daily. |
| Geriatric use | Use same dose as standard adult dosing (1 mL intravenously once daily). Caution due to increased risk of vitamin toxicity in elderly with reduced renal function. |
| 1st trimester | Consult provider |
| 2nd trimester | Consult provider |
| 3rd trimester | Consult provider |
Clinical note
Comprehensive clinical and safety monograph for MULTIPLE VITAMINS INJECTION PEDIATRIC (MULTIPLE VITAMINS INJECTION PEDIATRIC).
| Breastfeeding | Vitamins are naturally present in breast milk; supplementation with standard pediatric multivitamin doses is considered compatible with breastfeeding. No specific M/P ratio data for this combination product; individual vitamins have ratios near 1.0 for water-soluble vitamins and vary for fat-soluble vitamins. Excretion of additional vitamins into milk is minimal at therapeutic doses. No adverse effects in nursing infants reported. |
| Teratogenic Risk | Vitamin A (as retinol) in doses exceeding the RDA (≥10,000 IU/day) is teratogenic in the first trimester, associated with CNS, cardiovascular, and craniofacial defects. Standard pediatric injection doses (typically ≤5,000 IU vitamin A) fall below this threshold. Vitamin D, E, B-complex, and C have no established teratogenic risk at recommended doses. No fetal risk from other components (folic acid, biotin, etc.) at therapeutic levels. Overall, low teratogenic risk when used at recommended pediatric doses. |

| Fetal Monitoring | Monitor for signs of vitamin A toxicity (e.g., pseudotumor cerebri, hepatotoxicity) if high cumulative doses are used. Ensure serum levels of vitamins A and D do not exceed upper limits. In pregnancy, avoid exceeding recommended daily allowances; monitor liver function tests and calcium levels if prolonged therapy. No specific fetal monitoring required beyond standard obstetric care. |
| Fertility Effects | No known adverse effects on fertility at recommended doses. Excessive vitamin A (hypervitaminosis A) may impair fertility; standard pediatric doses do not reach toxic levels. No data suggesting negative impact on spermatogenesis or oogenesis. |
