PYRIDOXINE (VITAMIN B6) TOXICITY LITERATURE REVIEW

The literature from 1940 through June 1963 was surveyed to summarize the data from pyridoxine toxicity studies in animals and to ascertain the highest doses of pyridoxine (vitamin B6 analogs) that have been administered to human subjects as a therapeutic measure with no clinical evidence of toxicity. Analysis of the data indicated that doses of 25 mg/% pyridoxine hydrochloride should be well tolerated as a therapeutic measure when required. In particular, pyridoxine hydrochloride can be used when required in the specific treatment of a clinical entity such as acute UDMH intoxication.
