Thank you for your query.
I presume NUKLAST contains the salt monteleukast, which is used for treatment of asthma
and allergic rhinitis
. I would refrain from giving this medicine to an infant till there is evidence of allergy
to an item which cannot be avoided from the infant's environment.
A simple saline nasal drop would have helped to clear the blocked nose. Secondly continuous use of nasal medication can also lead to nasal discharge which is known as rhinitis medicamentosa
. As an alternative you can try steam inhalation.
I hope I have answered your query to your satisfaction.
