Hi,I had gone through your query and understand your concern.
I see similar similar cases in my clinic.In the first meeting,I try to rule out asthma to this patient having
allergic rhinitis.I look for allergens like cold,dust,animal dander,
smoking,respiratory infection etc.Again I look for asthma symptoms like cough ,wheeze or
chest tightness ,breathlessness etc and examine the
nasal cavity to see any abnormality.
If no asthma symptoms and organic problems are found out,then I advice:
>Avoid allergens so far it is possible
>Wash nasal cavity with water or normal saline
>Oral antihistamine like cetrizine
>
Steroid nasal spray
Then ask the patient to come back for follow up after 2 months.If patient follows above advice,he/she is found symptoms free in most of the time.
Since this is a prescription medicine, I would suggest your husband to meet the local Doctor to confirm the diagnosis.
Hope this answers your query.
Wish your husband good health.
