Is methycobal 500 used for treating neuralgia? compared to neurobion, neurogen e, which is more effective?

Vitamin B12: Vitamin B12 is used to treat peripheral neuropathy that is due to a deficiency in vitamin B12. There is not a lot of research into head-to-head comparisons of the efficacy of over the counter medications (including vitamins). Just make sure to normalize your vitamin B12 level if it is low. See your neurologist for further discussion. http://www.nlm.nih.gov/medlineplus/druginfo/natural/926.html
