Nausea/Vomiting
"I am pregnant and have been suffering from severe nausea and vomiting.  I have been taking Zofran for about 25 weeks.  The disolving tablet doesn&#039;t have an affect on me.  I can&#039;t keep it down, even after half an hour I will throw up the medication.  The rare times I can hold it down, it has no affect on me."
