Hi, Laurie. I am so sorry about your first baby.
Hugs to you.
As far as the Zofran goes, it has been the drug of choice for HG for years and we are not seeing any increases in birth defects. The place to check for the specific information you're asking about is Motherisk, a group that studies any and all medicines and chemicals for effects on babies. Their website is
www.motherisk.org , and you can call or e-mail a question if you don't see what you need there.
There are many, many other options than those you tried last time. It's a matter of trial and error, but researching into possibilities now will make a big difference. How far along are you? Are you trying anything other than Zofran?
