Is it ethical for an anesthesiologist to deliberately give me zofran (ondansetron) during surgery when i'm intolerant & have a red arm band with it listed?

Possibly okay: If you have an intolerance to zofran (ondansetron) but not a true drug allergy, it may not be as harmful as you think to get this medication. There are other anti-nausea medications but most don't work as well as zofran (ondansetron). Vomiting during general anesthesia can be dangerous if you have anything in your stomach so this is a serious concern. In general, doctors should discuss meds with patients before giving them.

Ethics: If one is not allergic to a medication, a red arm band should not be placed on the patient. Certain surgeries are more emetogenic than others. And as such warrants preemptive management. What would be unethical is to let you experience nausea and vomiting to prove his/her point.

Yes: A zofran (ondansetron) intolerance is not an allergy. The physician has to make a judgement about wether it is best to prevent nausea and vomiting that is frequent with this surgery, or allow the patient to have problems after the operation. It would be unethical for any doctor to do something to a patient that they had specifically been told not to. However, this case does not qualify as this.
