<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi - my son is 5 years old, he has been having cough for last 3 weeks, yesterday went to doctors office. They have given amoxycillin as he has pain in his body head ache mucus. He is feeling restless, seems he is feeling heat in his legs. He has taken the medicine twice today.  <response>: Hi, Amoxicillin is an antibiotic which means that the doctor has found a bacterial infection. If the child suffers from body ache and headache you can give him acetaminophen or ibuprofen syrup every 8 hours to resolve the body ache and headache. If he is having cough with phlegm then you can use a cough expectorant as Murine. You can also use a cough suppressant as Dextromethorphan. Hope I have answered your query. Let me know if I can assist you further.
