Some vitamins may help reduce nausea in women with hyperemesis gravidarum, including pyridoxine and vitamin B6. Typical dosages are between 10 and 25 milligrams, three times a day, but overdosing can lead to nerve damage. Thiamine (vitamin B1) in small doses may also lessen the amount of nausea and vomiting one experiences. A doctor must approve any and all treatments for hyperemesis gravidarum, to ensure harm does not befall mother or baby.
