###Human: Will giving Budecort and Montelukast to a child cause any side-effects? ###Assistant: Hi. Please note that Budecort inhaler is the medicine to prevent or reduce these instances and Asthalin is the emergency medicine to control sudden bouts. Hence, without fail you should start and continue using Budecort along with Montelukast and use Asthalin on SOS basis. As far as the question regarding allergy to certain items goes, it is best to observe the child for the same rather than doing umpteen number of tests just for finding the causative allergens. Any which ways the chances of you preventing the child from coming in contact with such an allergen would be less only. So do not worry much about the allergens point of view.
