PHARMACOLOGICAL ACTION:
Riboflavine is bound to plasma proteins. A little is stored in organs such as liver and kidneys, and amounts in excess of the body's requirements are excreted in the urine.
Thiamine is fundamentally associated with carbohydrate metabolism.
By combining with the pyrophosphoric acid in nucleated cells, particularly in the liver, kidneys and white blood cells it is converted in the body to its pyrophosphate which acts as coenzyme in such reactions as the decarboxylation of alpha-keto acids, particularly of pyruvate and alpha-keto-glutarate. In the presence of thiamine deficiency pyruvic and lactic acids accumulate in the tissues.

INDICATIONS:
Vitamin B complex injection is a dietary supplement where a deficiency of vitamins exists.

DOSAGE AND DIRECTIONS FOR USE:
Deficiency can be reversed by thiamine in doses as small as 500 micrograms daily.
A therapeutic dose of 1 to 2 mL daily is recommended.
Ampoule: IM or slowly and with caution IV 
Vial: For IM use only. 

SIDE EFFECTS AND SPECIAL PRECAUTIONS:
Vitamin B complex injection is usually well tolerated. It must be injected slowly.
