hello doctor my son had severe allergic cough from one month so he was prescribed with budecort inhaler and levolin inhalers, after using these , cough is getting controlled but not getting cured completely. I want to no should we use these inhalers only when he has too much cough or should we use it for normal cough also. and after stopping this inhalers if there is cough again should we continue with inhalers or a normal cough syrup is enough.
