** Thanks for contacting with your health concern 1. although nausea, vomiting, diarrhea are documented ADR [adverse drug reaction] of the drug but two major points to remember are: i. use of amoxicillin-clavulanate is associated with candida superinfection which could be responsible for diarrhea as suggested by multiple loose or watery bowel movements, without blood or mucus. ii. Use of the drug can cause Clostridium difficile associated diarrhea [which can cause mild diarrhea or severe inflammation of the colon and resulting bleeding], so my recommendation is - many cases can be resolved without antibiotic treatment and this will resolve the problem, however, if the antibiotic is still required, there should be discontinuation of the implicated agent [amoxicillin-clavulanate in your case] and substitute it with a drug less likely to cause this complication. [mine preferred choice would be oral metronidazole]. 2. If a new fever has arisen check with your doctor to exclude any other superadded infection.
