Can anyone help me

My daughter have been since Friday night with coughing congestion fever and vomiting. We took her to the Hospital. The doctor said she have upper respiratory infection and ear infection. Prescribed her some cough medicine and Amoxicillin. Come to find out she can not take the cough medicine. She will throw it up right back up.

Present. She had an appointment with Pediatrician she had said to stop giving her the cough medicine and start giving her OTC medicine. But she still got to take the Amoxicillin. We had start giving her OTC medicine that same day. The cough haven’t eased up on her. She will cough like crazy to the point to where she will throw up everything that she had drunk and ate. She will not eat much. I have lost sleepless night just stay up with her or watch over her while she’s asleep. She have an humidifier I have been using that every night. I keep her out this weather much as I can. Can anyone help with me this.
