Over the centuries, the dietary and biochemical essentiality of pyridoxine in the humans has been well established. Apart from various physiological functions, pyridoxine is therapeutically important in Nausea and Vomiting of Pregnancy (NVP). Pyridoxine on its own or a combination of pyridoxine (vitamin B6) (pregnancy category A) and doxylamine (category B), previously available as Bendectin, is the only medication that is specifically labeled for the treatment of NVP by the Food and Drug Administration.
