<s>[INST] My 5 yr old had an ear infection about 15 days ago. He was given keflex at first. The beginning of this week we took him back to the dr s and his ear infection was worse and now put on amox 400mg susp. He has been stating that his stomach is upset, head hurts in the forehead area, and has dark circles under his eyes. Is this normal with sinus issues? My pediatricion stated there is nothing to worry about and to cont to take the medication. We are just concerned. [/INST] Hello, Amox is strong enough antibiotics for ear infection. Stomach upset like loose motion is a usual side effect of it. It may be due to the same he is not getting enough rest and having dark circles or head hurting. You can use some probiotics like Darla or Sporadic for stomach upset or use more curd in food. Finish the course of antibiotics as prescribed. Hope I have answered your query. Let me know if I can assist you further. </s>
