Hello Thanks for the query Here I want to inform about some facts. Boys with nephrotic syndrome had three times higher incidence of bronchial asthma than the general population. Both boys and girls with NS had about three times more allergic rhinitis than the general population. Cough with sneezing without any noisy breathing and respiratory difficulty goes in favour of allergic rhinitis. Nebulisation with duolin will not help in this case. It will be helpful if there is associated narrowing of airways like in asthma as duolin acts as dilator of airways. In allergic rhinitis antiallergic like Levocetrizine, Allegra and allergy controller like montair will be helpful. There are some known side effects of duolin like palpitation, tremor and dyselectrolytemia. So I would suggest you that you can use duolin nebulisation on as and when required basis particularly when there is assosiated noisy breathing or breathing difficulty. Till then give him Allegra tab. 30 mg twice a day for 5 days and Grllinctus syp. 5 ml thrice a day for 5 days. Consult a doctor to rule out asthma and for long term management of this problem. As there is no neurological problem at present and all reports are normal. No need to worry for squint problem. I hope this answers your query well Wish you and your family good health With regards
