I took zofran through out my last pregnancy which was 3 years ago. I now I have a healthy beautiful little girl with no health concerns. I was recently prescribed zofran again and I've taken it a few times. But after doing some research and getting some opinions I'm not sure if it the safest thing to take while pregnant anymore. So I'm going to try the b6 and unisom but I'm not sure how much to take. Does anyone know the correct dosage amount to take while pregnant for both unisom and b6?
