Side Effects


There have been rare reports of anaphylactoid reactions following large intravenous doses of thiamine. The risk, however, is negligible if thiamine is co-administered with other vitamins in the B group. There have been no reports of fatal anaphylactoid reactions associated with M.V.I. Adult.

There have been rare reports of the following types of reactions:

Dermatologicrash, erythema, pruritus

CNS — headache, dizziness, agitation, anxiety


Allergicurticaria, periorbital and digital edema

Drug-Drug Interactions

Physical Incompatibilities

M.V.I. Adult (Multi-Vitamin Infusion) is not physically compatible with DIAMOX® (acetazolamide) 500 mg, DIURIL® Intravenous Sodium (chlorothiazide sodium) 500 mg, or aminophylline 125 mg, ampicillin 500 mg or moderately alkaline solutions. ACHROMYCIN® (tetracycline HCl) 500 mg may not be physically compatible with M.V.I. Adult. It has been reported that folic acid is unstable in the presence of calcium salts such as calcium gluconate. Some of the vitamins in M.V.I. Adult may react with vitamin K bisulfite. Direct addition of M.V.I. Adult to intravenous fat emulsions is not recommended. Consult appropriate references for listings of physical compatibility of solutions and drugs with the vitamin infusion. In such circumstances, admixture or Y-site administratio n with vitamin solutions should be avoided.

Several vitamins have been reported to decrease the activity of certain antibiotics. Thiamine, riboflavin, pyridoxine, niacinamide, and ascorbic acid have been reported to decrease the antibiotic activity of erythromycin, kanamycin, streptomycin, doxycycline, and lincomycin. Bleomycin is inactivated in vitro by ascorbic acid and riboflavin.

Some of the vitamins in M.V.I. Adult may react with vitamin K bisulfite or sodium bisulfite; if bisulfite solutions are necessary, patients should be monitored for vitamin A and thiamine deficiencies.

Clinical Interactions

A number of interactions between vitamins and drugs have been reported which may affect the metabolism of either agent. The following are examples of these types of interactions.

Folic acid may lower the serum concentration of phenytoin resulting in increased seizure frequency. Conversely, phenytoin may decrease serum folic acid concentrations and, therefore, should be avoided in pregnancy. Folic acid may decrease the patient's response to methotrexate therapy.

Pyridoxine may decrease the efficacy of levodopa by increasing its metabolism. Concomitant administration of hydralazine or isoniazid may increase pyridoxine requirements.

In patients with pernicious anemia, the hematologic response to vitamin B12 therapy may be inhibited by concomitant administration of chloramphenicol.

Vitamin K may antagonize the hypoprothrombinemic effect of oral anticoagulants (see bolded statement under PRECAUTIONS).

Consult appropriate references for additional specific vitamin-drug interactions.

Drug-Laboratory Test Interactions

Ascorbic acid in the urine may cause false negative urine glucose determinations.
