How long does a typical 4mg pill of zofran (ondansetron) take to start working on nausea due to gastroenteritis. taken at the onset of symptoms, before any vomiting?

Specializes in Internal Medicine

Typically....: It usually begins to start relieving nausea within 30-60 minutes. Hopefully, you will get relief and not begin vomitting. If it doesn't help and/or your symptoms worsen, get back in touch with your doctor. Good luck!!
