Hello,
Thanks for posting your query at DoctorSpring.com
I am Dr.R.K and I am pleased to assist you.
Your doctor is having a stomach bug causing diarrhea and a possible gastritis.
Since you are on vacation and getting few tests done is not possible I would advise you the following.
1. Prilosec/omeprazole for her epigastric pain half an hour before breakfast
2. A course of probiotics which would help to have faster recovery from diarrhea.
3. Tylenol every 6 hours for fever
4. Tablet Ciprofloxacin with metronidazole twice a day for the stomach bug.
Give her enough fluids to keep her well hydrated.
I wish her a faster recovery with these medications.
Let me know if I can assist you further.
Regards,
Dr.R.K.
