title: [Pyridoxine neuropathies. Review of the literature].
abstract: Daily needs of vitamin B6 are very low (2 mg per day) and widely covered by normal feeding. Pyridoxine deficiencies are exceptional (congenital metabolic abnormalities, drug or toxic-induced perturbations). First described in animal models, human cases of neuropathy had been encountered in the "megavitamin"-syndrome. They are confirmed by rare case-reports of very high doses given in toxic indication. Sensory peripheral neuropathies can also occur with lower doses taken over a long period of time.
