Yeah the Zofran "study" is total ********. It's only if you're getting the 32mg IV dosage on a regular basis that any problems can occur. Those on 4-8mg pills or IV doses are perfectly fine. You can take up to 32mg per day, just not all at the same time. I'm part of a group of 3000 moms, all of who have been on Zofran, and not one of them has had issues from the Zofran. I'm on it myself, along with Diclegis.
