thank you for your query in healthcaremagic.com.... well its good that you are feeling much better regarding your throat abscess following antibiotics for 5 days...but can you tell me what antibiotic you were taking?...because there are a few of them which causes diarrhea in a number of patients.... in fact i can share my own experience and i had similar occurrence of diarrhea following a course of antibiotics and i had to change my compositions... your case also looks like antibiotic associated diarrhea... so this is not unnatural.... also the nausea and flushing is nothing to worry about....it will be alright eventually.... i would suggest you to take tablet pantoprazole-levosulpiride combination daily before breakfast for 7 days...if the diarrhea is severe then take combination normaxin-rt twice daily for 5 days.... hope this was useful... contact me for any further queries... regards
