Hi Arif Bhai,
Thank you for query.
Myteka and Zatofen are medicines for asthma
and from what you describe I do not think that these are needed for your child. In cough
or viral infection a simple cough syrup or decongestant syrup should do. It shall be better if you get your child re-examined and find if the medicines mentioned by you are indeed required.
I hope I have answered your query to your saisfaction.
Wishing your child all the best..
