Your kid has got Viral fever
is given to prevent secondary infection.Montair LC kid syrup has Antihistamine which clears running nose.It can also reduce Cough
Actually,kid should sleep well as Sedation is seen with Antihistamine Levocetrizine which is present in syrup.
As fever is present,Crocin
can be given in regular intervals.
In my opinion,it is better not to give Phenargan for your kid .In my experience,one patient has woke up after 12 hrs of giving Phenargan.It should be given under supervision of a Doctor.Better avoid it.
I wish good health for your kid and speedy recovery
