"],"dosage_and_administration":["2 DOSAGE AND ADMINISTRATION M.V.I.-12 is a combination product that contains the following vitamins: ascorbic acid, vitamin A, vitamin D, thiamine, riboflavin, pyridoxine, niacinamide, dexpanthenol, vitamin E, folic acid, biotin, and vitamin B 12 ( 2.1 ) Recommended daily dosage is 10 mL ( 2.2 ) Administer by intravenous infusion after dilution ( 2.1 ) M.V.I.-12 Pharmacy Bulk Package consists of two vials labeled Vial 1 and Vial 2. Aseptically transfer the contents of Vial 1 to Vial 2. The mixed solution (100 mL) will provide ten 10 mL single doses to patients in a pharmacy admixture program. Use within 4 hours of puncture ( 2.1 , 2.3 ) Prior to intravenous administration, dilute the once daily dose of 10 mL by adding to at least 500 to 1,000 mL intravenous parenteral nutrition solution containing dextrose or saline ( 2.3 ) After dilution in an intravenous infusion, refrigerate resulting solution unless used immediately. Use solution within 24 hours after dilution ( 2.3 ) Monitor blood vitamin concentrations ( 2.4 ) See Full Prescribing Information for drug incompatibilities ( 2.5 ) 2.1 Important Dosage and Administration Instructions M.V.I.-12 is a combination product that contains the following vitamins: ascorbic acid, vitamin A, vitamin D, thiamine, riboflavin, pyridoxine, niacinamide, dexpanthenol, vitamin E, folic acid, biotin, and vitamin B 12 . M.V.I.-12 is supplied as a pharmacy bulk package for intravenous use intended for administration by intravenous infusion after dilution: M.V.I.-12 Pharmacy Bulk Package : consists of two pharmacy bulk vials which must be mixed prior to use. The mixed solution will provide ten 10 mL single doses which must be diluted prior to intravenous administration. Pharmacy bulk package of M.V.I.-12 is intended for dispensing of single doses to multiple patients in a pharmacy admixture program and is restricted to the preparation of admixtures for infusion [ see Dosage and Administration (2.3) ]. Do not administer M.V.I.-12 as a direct, undiluted intravenous injection as it may cause dizziness, faintness, and tissue irritation. 2.2 Dosage Information The recommended daily dosage volume is 10 mL. One daily dose (10 mL) is diluted by adding directly to a specified volume of an intravenous fluid [ see Dosage and Administration (2.3) ]. Patients with multiple vitamin deficiencies or with increased vitamin requirements may need multiple daily dosages as indicated or additional doses of individual vitamins. 2.3 Preparation and Administration Instructions Handling of M.V.I.-12 solution, including preparation of the pharmacy bulk pack, should be restricted to a suitable work area, such as a laminar flow hood (or an equivalent clean air compounding area). Aseptically transfer the contents of Vial 1 (50 mL) into Vial 2 (50 mL). The mixed solution (100 mL) will provide ten 10 mL single doses to patients in a pharmacy admixture program. Each bulk vial closure shall be penetrated only one time with a suitable sterile transfer device or dispensing set that allows measured dispensing of the contents. Once closure system has been penetrated, complete dispensing from the pharmacy bulk vial within 4 hours. Mixed solution may be stored for up to 4 hours refrigerated. Discard unused portion. Visually inspect for particulate matter and discoloration prior to administration. Utilizing a suitable sterile automated compounding device or dispensing pin for accuracy, aseptically transfer each 10 mL dose into a plastic or glass bottle containing at least 500 to 1,000 mL intravenous parenteral nutrition solution containing dextrose or saline. After M.V.I.-12 is diluted in an intravenous infusion, refrigerate the resulting solution unless it is to be used immediately, and use the solution within 24 hours after dilution. Minimize exposure to light because some of the vitamins in M.V.I.-12, particularly A, D and riboflavin, are light sensitive. 2.4 Monitoring Vitamin Blood Levels Blood vitamin concentrations should be monitored to ensure maintenance of adequate levels, particularly in patients receiving parenteral multivitamins as the only source of vitamins for long periods of time. 2.5 Drug Incompatibilities M.V.I.-12 is not physically compatible with moderately alkaline solutions such as a sodium bicarbonate solution and other alkaline drugs such as acetazolamide sodium, aminophylline, ampicillin sodium, and chlorothiazide sodium. Folic acid is unstable in the presence of calcium salts such as calcium gluconate. Vitamin A and thiamine in M.V.I.-12 may react with bisulfite solutions such as sodium bisulfite or vitamin K bisulfate. Patients should be monitored for vitamin A and thiamine deficiencies. Do not add M.V.I.-12 directly to intravenous fat emulsions. Consult appropriate references for listings of physical and chemical compatibility of solutions and drugs with M.V.I.-12. In such circumstances, admixture or Y-site administration with M.V.I.-12 should be avoided."],"dosage_forms_and_strengths":["3 DOSAGE FORMS AND STRENGTHS M.V.I.-12 is an injection available as: Pharmacy bulk package consisting of two vials labeled Vial 1 and Vial 2.

Methotrexate: Folic acid may decrease a patient's response to methotrexate therapy. Levodopa: Pyridoxine may increase the metabolism of levodopa (decrease blood level of levodopa) and decrease its efficacy. Antibiotics: Thiamine, riboflavin, pyridoxine, niacinamide, and ascorbic acid decrease antibiotic activities of erythromycin, kanamycin, streptomycin, doxycycline, and lincomycin. Bleomycin: Ascorbic acid and riboflavin inactivate bleomycin in vitro, thus the activity of bleomycin may be reduced. 7.2 Effect of Other Drugs on M.V.I.-12 Hydralazine or Isoniazid: Concomitant administration of hydralazine or isoniazid may increase pyridoxine requirements. Chloramphenicol: In patients with pernicious anemia, the hematologic response to vitamin B 12 therapy may be inhibited by concomitant administration of chloramphenicol.

Aluminum may reach toxic levels with prolonged parenteral administration in patients with renal impairment. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum. Patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 micrograms per kg per day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration. To prevent aluminum toxicity monitor periodically aluminum levels with prolonged parenteral administration of M.V.I.-12. 5.2 Risk of Low Vitamin A Levels Vitamin A may adhere to plastic, resulting in lower vitamin A concentrations after administration of M.V.I.-12. Therefore, blood vitamin concentrations should be periodically monitored and the administration of additional therapeutic doses of Vitamin A may be required. 5.3 Allergic Reactions to Thiamine Allergic reactions such as urticaria, periorbital and digital edema, have been reported following intravenous administration of thiamine, which is found in M.V.I.-12. There have been rare reports of anaphylactoid reactions following intravenous doses of thiamine. No fatal anaphylactoid reactions associated with M.V.I.-12 have been reported. 5.4 Hypervitaminosis A Hypervitaminosis A, manifested by nausea, vomiting, headache, dizziness, blurred vision, has been reported in patients with renal failure receiving 1.5 mg/day retinol and in patients with liver disease. Therefore, supplementation of renal failure patients and patients with liver diseases with vitamin A, an ingredient found in M.V.I.-12, should be undertaken with caution [ see Use in Specific Populations (8.6 and 8.7) ]. Blood levels of Vitamin A should be monitored periodically. 5.5 Interference with Diagnosis of Megaloblastic Anemia Patients Avoid the use of M.V.I.-12 in patients with suspected or diagnosed megaloblastic anemia prior to blood sampling for the detection of the folic acid and cyanocobalamin deficiencies. M.V.I.-12 contains folic acid and cyanocobalamin which can mask serum deficits of folic acid and cyanocobalamin in patients with megaloblastic anemia. 5.6 Potential to Develop Vitamin Deficiencies or Excesses In patients receiving parenteral multivitamins, such as with M.V.I.-12, blood vitamin concentrations should be periodically monitored to determine if vitamin deficiencies or excesses are developing. M.V.I.-12 may not correct long-standing specific vitamin deficiencies. The administration of additional doses of specific vitamins may be required [ see Dosage and Administration (2.2) ]. 5.7 Interference with Urine Glucose Testing M.V.I.-12 contains Vitamin C which is also known as ascorbic acid. Ascorbic acid in the urine may cause false negative urine glucose determinations."]}
