Vitamin B6 can be used by pregnant women during pregnancy. Vitamin B6 belongs to the B class of drugs and is relatively safe to be applied by pregnant women during pregnancy. Women may experience vomiting, nausea, and gastrointestinal reactions during early pregnancy due to early pregnancy reactions, and if the symptoms are severe they can be given vitamin B6 tablets 2x/day, 10mg/time orally. For women with severe vomiting in pregnancy, they can also be hospitalized with water fasting, given energy supplements, and can also be given vitamin injections for intravenous drip, which serves to correct the early pregnancy reaction during pregnancy. However, there are relatively few medications that can be used by pregnant women during pregnancy, and any medications that need to be taken must be reviewed by a physician before they can be applied.
