Thank you for your query at DoctorSpring.com
I understand your concern.
It seems like in addition to the throat infection, you also picked up a GIT infection leading to diarrhea and vomiting. Can you please mention which antibiotic you used? Some antibiotics can also lead to similar manifestations.
For the next few days, I will advise you the following medicines:
1) Tab. Loperamide SOS - to control the frequency of diarrhoea.
2) Tab. Ondansetron 4 mg thrice daily 30 minutes before each meal.
3) Plenty of fluids.
4) Cap. Omeprazole 20 mg twice daily.
Please continue this treatment for 3 days, and let me know if there is improvement.
Hope this was helpful,
