nausea/vomiting
"16 year old daughter was having headaches and was doing infusions with medications. Used Zofran for nausea. Immediately after it was injected she had a severe allergic reaction, could not breathe, felt her throat tighten up, shortness of breath, dizziness, anxiety, shivering and sweating. Oxygen was given and this passed quickly within 5 minutes. Was observed in ER and there were no other effects after that episode."
