Ondansetron might be bad for migraine. FDA have issued a warning. When you read te packet information you see that in the chemotherapy setting the commonest minor side effect of ondansteron is in fact a headache – so maybe this makes it a poor choice for treating a migraine? I think we need a trial, but for now I am using a dopaminergic agent first line.
