to tell them it's not working?
I was given Zofran for extreme nausea with some vomiting and major *TMI* diarrhea every 30 minutes to 1 hour for over 12 hours and becoming severely dehydrated. Two days before starting the Zofran, I was itchy EVERYWHERE but very mild. However, the day I started the Zofran, the itching intensified all crazy. Now it's not just mild but SUPER FREAKING ITCHY EVERYWHERE!!!
So they changed my prescription and wanted me to call back if the itching persisted. It has been over 24 hours since taking the Zofran and I am still SUPER SUPER SUPER ITCHY EVERYWHERE. I called and they put a note into my doctor and told me to try Benadryl to see if that helped. If not, the itching may not be related to the medicine at all, just coincidental that my itching went from mild to severe around the same time.
It's only been 30 minutes since my first dose of Benadryl and I am still super extremely itchy absolutely everywhere. How long does it take to kick in? How long should I give it before calling and letting them know that it did not work (if it doesn't)?
