Hi, i carefully read your question and got your point. The problem started after you are given broad spectrum antibiotics I ve seen so many patient in my clinic with such problem you are facing. Amoxacillin and especially azithromycin cause severe gastrointestinal upset and diarrhea. I recommend my patient take them on empty stomach. You should not worry about the pain abdomin and loss of appetite as you will feel better when you stopp these antibiotics. I recommend my patient to take cefadroxill and metronidazole after tooth extraction. You can contact with your local doctor as these are priscription based drugs. I hope you will be satisfued with my answer, please do not hesitate in asking from Healthcaremagic.
