Here's what I found on the internet:
1. Vitamin B6 has been proven to improve morning sickness at a dosage of 100 milligrams or less per day.
2. The Food and Drug Administration (FDA) has approved Diclegis (doxylamine succinate and pyridoxine hydrochloride) for morning sickness treatment.
3. Acu pressure wristband
My sister suffered from severe morning sickness and couldn't eat or drink anything. She was already thin and lost even more weight because she couldn't keep anything down throughout the day. This led to dehydration, but thankfully, a visit to the ER resulted in her being prescribed Zofran. I hope she feels better and find relief. If none of the suggested remedies work, please take her to the ER and I am certain that someone there will be able to help her. Make sure to let the ER doctor know that she also has low iron. Even though your daughter is having a baby, she's still your baby and as a mom you want to help her. Please keep us updated.
