The symptoms as mentioned suggest that the cough might be allergic in nature.
Ascoril expectorant contains Salbutamol
which is a bronchodilator; Guaiphenesin which is an expectorant & Bromhexine
which is a Mucolytic
These act as a measure for providing relief during acute attacks.
Whereas Montair is Montelukast
, which is used as a maintenance therapy to relieve symptoms of seasonal allergies...it acts more as a preventive measure.
So...the medications given by the Pediatrician
are correct...please continue them as advised.
Antihistaminic preparations may also be used to provide symptomatic relief.
Also maintain adequate hydration & give soft foods to maintain proper nutrition.
The best thing would be to make sure that your child is well protected from cold, dust & other allergens.
Wishing him a good health.
Thanks & take care.
