It takes about 48-72 hours after starting antibiotics to see the response. So you can wait till then provided she is not very lethargic and taking food as usual. Give paracetamol every 6 hours for initial two days, Chat Doctor. If not coming down by 48-72 hours, kindly take her back to doctor for reviewing the diagnosis, or changing the antibiotics. Hope I have answered your question. Let me know if I can assist you further.
