Vitamin B6 is thought to lead to neuropathy due to its cytoskeletal and microtubule toxicity leading to nerve cell loss with prolonged overdosing. [ 2 ] Possible infectious causes of sensory neuronopathy include HIV (in which lymphocyte infiltrates have been observed in the dorsal root ganglion), Human T-lymphotropic virus 1 , Epstein-Barr ...
Hypervitaminosis is a condition of abnormally high storage levels of vitamins, which can lead to various symptoms as over excitement, irritability, or even toxicity.

There are several causes of toxic optic neuropathy. [1] Among these are: ingestion of methanol (wood alcohol), ethylene glycol (automotive antifreeze), disulfiram (used to treat chronic alcoholism), halogenated hydroquinolones (amebicidal medications), ethambutol and isoniazid (tuberculosis treatment), and antibiotics such as linezolid and chloramphenicol as well as chloroquine and the related ...
A common side effect is numbness in the hands and feet, also known as peripheral neuropathy. [18] Co-treatment with vitamin B 6 alleviates the numbness.

A sudden-onset sexual anhedonia can also be a symptom of sensory neuropathy, which is most commonly the result of pyridoxine toxicity [4] (e.g., from large doses of vitamin B6 supplements). In this case, the sexual dysfunction promptly resolves spontaneously once the B6 supplementation is stopped. [citation needed]
Pyridoxine (PN) [4] is a form of vitamin B 6 found commonly in food and used as a dietary supplement.As a supplement it is used to treat and prevent pyridoxine deficiency, sideroblastic anaemia, pyridoxine-dependent epilepsy, certain metabolic disorders, side effects or complications of isoniazid use, and certain types of mushroom poisoning.
