Hi,
Welcome to Healthcaremagic.com.
I had gone through your question I can understand your concern about your wife.
You must not take too much of medication for a purpose which even has not been properly diagnosed. If your wife has loose motions since morning and recovery seems to be possible it can only be the episode of food
poisoning. Which only needs the proper rehydration.
Put her on plenty of fluids with
ORS which you have done, no other medication except pain D is needed. In case the cramps are too annoying or there is associated blood in stools or
fever than you must give her antibiotic like one mentioned in above query.
I don't think there is need of three antibiotics at the reason which even does not need one as per my opinion. Misuse of antibiotics can be dangerous in future life. Because resistance to these antibiotics if not used properly becomes costly in future.
Keep her hydrated, use only NorfloxTz, and ORS.
Hope you will understand my point of view,write us back in case you need any further assistance we will be happy to help.
Regards
Dr Muzaffer Hussain Parray.
