zofran is safe :). there are 2 nausea medicines that are considered safe for pregnancy, and
zofran sounds like the better choice for you (since phenergan makes you sleepy, and that's the other option, i think it would freak you out!). every medicine is going to carry warnings, and there will be people who SWEAR that this medicine caused this or that...but that's the internet for you. it is considered safe, and your OB only prescribed it because they felt it was safe....
