How to treat a 2-year-old child with a cough and phlegm

Patient's question:

Child 2 is 18 years old, coughing, with phlegm in the throat, and yellow nasal mucus. They self-prescribed medication: Amoxicillin, Chai Yin oral liquid, Houtou San, and Acetylcysteine granules. Is it okay to take these medications this way? They have already taken them, will they interact? Thank you

Doctor's answer:

I'm glad to help you solve your problem. Based on your description, it's possible that the child may have a bacterial infection. Amoxicillin can be taken orally, but it's better to decide between Amoxicillin-clavulanate potassium or a cephalosporin antibiotic for anti-infection treatment. Either Chaiyin oral liquid or Huazao powder can be chosen, and acetylcysteine granules can be taken orally to relieve phlegm.
