Highly variable by component; e.g., ascorbic acid: 8-40 days (depletion), thiamine: 9-18 days, pyridoxine: 2-3 weeks, fat-soluble vitamins: vitamin A: 2-3 months (liver stores), vitamin D: 15-25 days, alpha-tocopherol: 17-19 days, vitamin K: 2-3 hours (short). Clinical context: half-life reflects tissue storage and turnover; chronic dosing leads to accumulation for fat-soluble vitamins.
Variable by vitamin: thiamine ~24h, riboflavin ~18h, pyridoxine ~30h, cyanocobalamin ~6 days, ascorbic acid ~8h, retinol ~20h, ergocalciferol ~19 days, alpha-tocopherol ~10h, phytonadione ~4h. Clinical context: short t1/2 of water-soluble vitamins requires daily dosing; long t1/2 of fat-soluble vitamins allows less frequent dosing but risk of accumulation.
Vitamins are metabolized in the liver (e.g., vitamin A to retinoic acid) and other tissues; some undergo hepatic hydroxylation (e.g., vitamin D), conjugation (e.g., folic acid to tetrahydrofolate), or oxidation (e.g., pyridoxine to pyridoxal phosphate).
Vitamins are metabolized via various pathways in the liver and tissues, including phosphorylation, dephosphorylation, and oxidation-reduction reactions.
Renal: water-soluble vitamins (B-complex, C) are primarily excreted unchanged in urine; fat-soluble vitamins (A, D, E, K) are excreted in feces via bile. % varies by vitamin: e.g., thiamine 40-60% renal, ascorbic acid 50% renal; vitamin A >80% fecal.
Renal: water-soluble vitamins (B-complex, C) are excreted primarily via kidneys, with excess eliminated unchanged. Fat-soluble vitamins (A, D, E, K) are eliminated via bile and feces; renal excretion is minimal. Specific percentages: thiamine 80-90% renal, riboflavin 60-70% renal, pyridoxine 70-80% renal, cyanocobalamin 50-60% renal, ascorbic acid 60-70% renal; fat-soluble vitamins >90% biliary/fecal.
Variable: vitamin A (retinol) bound to retinol-binding protein (90-95%); vitamin D (25-hydroxycholecalciferol) to vitamin D-binding protein (50-60%); vitamin E (alpha-tocopherol) to lipoproteins (90%); vitamin K to albumin (50-80%). Water-soluble vitamins: minimal binding (<10%).
Variable: thiamine ~10% bound to albumin; riboflavin ~30% bound to albumin; pyridoxine ~60% bound to albumin; cyanocobalamin bound to transcobalamins (~20%); ascorbic acid ~5% bound; retinol bound to retinol-binding protein (RBP) ~100%; ergocalciferol bound to vitamin D-binding protein (DBP) ~90%; alpha-tocopherol bound to lipoproteins ~90%; phytonadione bound to lipoproteins ~95%.
Not applicable as a mixture; individual vitamins vary: vitamin A: 0.5-1.5 L/kg (liver storage), vitamin D: 0.5-1 L/kg, vitamin E: 5-10 L/kg (adipose tissue), vitamin C: 0.3-0.5 L/kg, B-complex: 0.2-0.5 L/kg. Clinical meaning: reflects distribution into tissues and storage compartments.
Extensive for fat-soluble vitamins: retinol ~5 L/kg, ergocalciferol ~10 L/kg, alpha-tocopherol ~10 L/kg; water-soluble vitamins have Vd approximating total body water: thiamine ~0.6 L/kg, riboflavin ~0.5 L/kg, ascorbic acid ~0.4 L/kg. Clinical meaning: large Vd indicates extensive tissue distribution and storage.
IV only (M.V.I. Adult is for IV use; oral multivitamins have variable bioavailability: water-soluble ~50-90%, fat-soluble 20-50% depending on formulation and food). Not applicable as oral product for this monograph.
Intravenous: 100%. No oral formulation; M.V.I.-12 is for IV use only.
No dose adjustment required for renal impairment. Use with caution in patients with severe renal dysfunction due to potential aluminum accumulation from excipients.
No specific dose adjustment required for renal impairment.
No specific dose adjustment for hepatic impairment. Use with caution in patients with severe hepatic dysfunction due to risk of vitamin accumulation and toxicity.
No specific dose adjustment required for hepatic impairment.
For children aged 11 years and older: same as adult dose (10 mL IV once daily). For children 2 to 10 years: 5 mL IV once daily. For infants and children under 2 years: use M.V.I. Pediatric formulation. Administer as infusion over at least 2 hours.
For children weighing <40 kg: 0.25 mL/kg/day (max 10 mL) intravenously once daily. For children weighing ≥40 kg: same as adult dose (10 mL once daily).
No specific dose adjustment recommended. Standard adult dose (10 mL IV once daily) is appropriate unless significant comorbidities or polypharmacy warrant caution. Monitor for adverse effects due to potential age-related decline in organ function.
Standard adult dosing; no specific geriatric adjustment required.

None.
Hypersensitivity reactions (including anaphylaxis) have been reported; contains aluminum (may be toxic with prolonged use in renal impairment); vitamin K can counteract anticoagulant therapy; vitamin A (retinol) hepatotoxicity with high doses; vitamin D toxicity with excessive doses; folic acid may mask pernicious anemia.

No specific food interactions. However, M.V.I. ADULT contains vitamin K; patients on warfarin should maintain consistent vitamin K intake. Avoid alcohol as it can affect vitamin metabolism.
No direct food interactions known as the drug is administered intravenously. However, patients on parenteral nutrition may have dietary restrictions based on underlying condition (e.g., renal, hepatic). Vitamin K content may affect warfarin therapy; monitor INR if applicable.
M.V.I. ADULT contains multiple vitamins and minerals. At recommended doses, most components are considered safe during pregnancy. However, high dose vitamin A (>10000 IU/day) is teratogenic in first trimester. Vitamin D excess may cause fetal hypercalcemia. No specific trimester risks for standard doses.
M.V.I.-12 Lyophilized contains vitamins A, D, E, K, C, B1, B2, B3, B5, B6, B9, B12. Vitamin A at high doses (>10,000 IU/day) is teratogenic in first trimester. Vitamin D excessive doses may cause fetal hypercalcemia. Vitamin K at high doses may increase neonatal jaundice risk. Folic acid supplementation is beneficial for neural tube defect prevention. Individual vitamin components should be reviewed; the combination product at recommended doses is generally considered low risk but requires monitoring of vitamin A and D levels.
M.V.I. ADULT components are excreted into breast milk in amounts that are generally considered safe. No specific M/P ratio available. Use with caution to avoid excessive maternal intake of fat-soluble vitamins.
Most components are excreted into breast milk, but the product at recommended doses is compatible with breastfeeding. The milk-to-plasma ratio varies by component; for example, vitamin A M/P ratio is approximately 0.5-0.7, vitamin D is low. High doses of vitamin A or D may accumulate in infant and should be avoided. Caution with vitamin K if infant has deficiency or bleeding risk.
No dose adjustment required for M.V.I. ADULT during pregnancy. Standard recommended daily allowances apply.
No specific dose adjustments required for pregnancy; use standard dosing. Ensure that vitamin A does not exceed 10,000 IU/day to avoid teratogenicity. Monitor for increased needs of folic acid (400-800 mcg/day) and iron (if part of separate regimen). Pharmacokinetic changes in pregnancy (e.g., increased plasma volume) do not necessitate dose changes for this multivitamin product.
