Hi, I am Dr Suresh K Yadav MD (paediatrics), I had gone through your question and understand your concerns, Most likely your problem seems to be related to allergy or asthma , in that case inhalation prophylactic therapy is recommended if symptoms ( cough ) are occurring daily and not responding to montec LC . Best and safest is regular use of inhalational steroids with reliever medicine like salbutamol inhalation as and when required . Inhalation therapy is relatively safe on long term use . You also need annual influenza shots. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions Take care.
