A long-standing dry cough that comes every winter is most likely due to allergy-related airway sensitivity such as Allergic Bronchitis or Seasonal Allergic Rhinitis. Try to avoid cold air and dust, use a mask outdoors, take steam inhalation, and drink warm fluids regularly. Antihistamines like Levocetirizine or inhalers (if prescribed) may help control symptoms better than cough tablets alone. Since this is recurrent every year, consult a chest physician about preventive allergy treatment or inhaler therapy before winter starts.

Your child?s symptoms suggest a respiratory infection with mucus, and the prescribed medicines, Cepodem, Allercent DC, and a cough medicine like Deletus are commonly used and generally appropriate if advised by a doctor. Make sure the full antibiotic course is completed, give plenty of warm fluids, and use steam inhalation if suitable for the child. If breathing difficulty, high fever, or no improvement in 2?3 days occurs, consult the doctor again.
