nausea/vomiting
"I've been taking ondansetron ODT 8mg tabs for about 2 days due to nausea caused by a kidney infection. When I take the tablet it doesn't help and makes me more nauseous than I was before. I just took it a half hour ago to be sure, and I immediately became more nauseous. So I'm pretty sure it just doesn't work for me, and I'm wondering if anyone else has this problem?"
