Hello - I am currently 19 wks pregnant and I took Zofran from about week 8 through week 14. It helped some but I still had almost constant nausea. It did help keep me from getting to the point where I couldn't eat anything (which is where I was when I went to get a prescription). 2 weeks ago I had an amnio and hi-res ultrasound (some of it 3-D) and results were excellent for both - dr. said everything is progressing as normal - physical and mental development, weight gain, etc.
Zofran is very expensive - with my prescription copay I paid about $7.00 per pill and I had to take 4 a day. If you have to take them for 6 weeks as I did that works out to over $1100.
My bout with nausea really crippled me - I used to work out about 5x a week, but once I got sick it was all I could do to get to work and come home and do laundry. I hope you will not have that experience, but if you do here's what I tried (please note that this is NOT medical advice, just what helped me get through the misery):
1. Eat whatever you want. The baby will be fine - it will suck all it needs out of you (or so says my mom the OB nurse and my husband the Dr.)
2. If you are on a huge prenatal vitamin that makes you sick, see if your dr. can get you a prescription for a prenatal vitamin that helps with nausea. My OB gave me one and again, it helped a little. But when you are miserable, you'll take everything you can get.
3. Try and keep your stomach from being completely empty. My OB recommended Kool-aid to help keep my tummy going.
4. Eat first thing when you get out of bed, relax a little bit, then hop in the shower.
5. Take a lot of naps. I always felt almost normal in the moments after I woke up from a nap. Plus the more you're asleep, the less you feel yucky!
Also, here's a list of the stuff I tried that didn't help:
1. Peppermints
2. Ginger candy/pills
3. Emetrol
4. Sea Bands
5. Lemon lime sodas
Good luck. It does go away. Mine finally died off about a week ago!
