nausea/vomiting
"I had a very serious vomiting problem with my first pregnancy. I had to be hospitalized and then put on an IV at home for fluids. When I was about two months pregnant with my second child I was given promethazine, and it was the only thing that kept me from the same issues as the first pregnancy. I was still sick everyday, and I was still vomiting sporadically. However, I was able to actually eat and drink and gain weight. My son was born fine. Now I am pregnant with my third and have started on it earlier than the second pregnancy. I was not aware that the effects of the drug on unborn children is unknown. My doctor had told me it was safe. Hopefully this next baby will be fine as well."
