Hi. Thanks for your question. The symptoms of yours seem to be because of the adverse effect of Amoxyclav. Though i will like to exclude other reasons as well by asking you certain questions: For how many days and at what dose you are prescribed the medication? Are you on any other medications? Do you have Fever,Body ache,Loose motion,Skin rash? Common Side effects of Amoxyclav include: Abdominal cramps Nausea Vomiting Skin rash Convulsions Complete the course of the drug as prescribed by your doctor.Discontinuing antibiotics before full course usually causes recurrence of infection and development of resistance to the antibiotic for future. Usually the symptoms subsides by itself within few days and there is nothing to worry. However i will advice you certain medications which you can take in case the symptoms persist. Proto pump Inhibitor like Omeprazole Anti-Spasmodic Drugs like Drotaverine for the abdominal cramps. Domperidone for nausea and vomiting. Probiotic preparation along with will also be helpful. Also take care to maintain adequate hydration especially during vomitting. Wishing you a speedy recovery. Best wishes
