Anyone else fail Zofran?

Alissa

My OB prescribed Zofran/Ondansetran for my horrible nausea/vomiting recently and I’ve taken it a few times with no relief (in fact, I vomited severely about an hour after taking it 2 out of 3 times).

Wondering if Zofran has failed others and if so, did you find another medication that worked for you?

Thanks!
