Toxicity Profile

Route of ExposureOral; parenteral (intramuscular). The B vitamins are readily absorbed from the gastrointestinal tract, except in malabsorption syndromes. Pyridoxine is absorbed mainly in the jejunum.
Mechanism of ToxicityVitamin B6 is the collective term for a group of three related compounds, pyridoxine (PN), pyridoxal (PL) and pyridoxamine (PM), and their phosphorylated derivatives, pyridoxine 5'-phosphate (PNP), pyridoxal 5'-phosphate (PLP) and pyridoxamine 5'-phosphate (PMP). Although all six of these compounds should technically be referred to as vitamin B6, the term vitamin B6 is commonly used interchangeably with just one of them, pyridoxine. Vitamin B6, principally in its biologically active coenzyme form pyridoxal 5'-phosphate, is involved in a wide range of biochemical reactions, including the metabolism of amino acids and glycogen, the synthesis of nucleic acids, hemogloblin, sphingomyelin and other sphingolipids, and the synthesis of the neurotransmitters serotonin, dopamine, norepinephrine and gamma-aminobutyric acid (GABA).
MetabolismHepatic. Half Life: 15-20 days
Toxicity ValuesLD50: 4 gm/kg (oral, rat)
Lethal DoseNone
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Minimum Risk LevelNone
Health EffectsNone
TreatmentAdminister charcoal as a slurry.
