Why Am I Coughing Even After Taking Cheratussin And Zpak For Asthma?

I have the flu w/asthma and was prescribed Cheratussin AC (bronchitis) and Zpak but am still coughing. I was trying to see what the dosage for an adult may be. Mine is 5ml every 8 hrs. I tried looking it up and that seems to be the children s dosage. It was not my regular doctor, but a walk in clinic PA. I am thinking of switching to plan Robitussin or Robitussin DM at night. Please advise

Hi,

Cheratussin AC and Robitussin contain codeine and guaifenesin as principle actives.

I usually prescribe it at a dose of 10 ml every 8 hours until symptoms improve.

I also advise to:
- drink more water
- do gargle with water and salt
- keep good oral hygiene
- take acetaminophen/ibuprofen for the pain or fever

All the best!
