Hello Susmita
Since you are from India , so you will understand better .
First of all I want to tell you that your 17 years old daughter is having
allergic rhinitis and this is a precursor of asthmatic allergic
bronchitis and later on turn into ASTHMA , if proper care in not taken.
Causative or triggering factors for this
allergy are , dust , mite , hay , fodder, fine dusting powder, sudden fall and rise of temperature , pollen, mold , smokes , pests ( cockroaches ) , pets in house.
If possible take care about avoidance .
These measures also help:
-Wash all bed covers in hot cycles ( 60 degree C).
-Treat carpets with
tannic acid.
Keep dust accumulating objects in dust cupboard.
-Replace curtains with washable curtains( rich source of fine dust of house).
-Use vacuum cleaner.
-Keep pets out of house & bedrooms.
-Install air conditioner or dehumidifier .
Since your daughter is taking alsaspan ( this is
loratidine and causes
drowsiness ) so avoid it.
When such patient visit my clinic I prescribe them to take MONTELEUKAST 10 mg in the night ( once in 24 hours).
Hot coffee and steam inhalation also provide instant relief.
Don't desperate as this is a most common disease in India and gradually your daughter will recover from this disease if above mentioned measures to be taken.
Hope this will help your daughter.
Good luck.
