Don't be so desperate & dejected .
I will try to explain you whole thing so that you will understand in better way.
Mite , dust , hay , fodder, mold , pollen , sudden fall & rise of temperature , humidity all are predisposing factors which are responsible for allergic asthmatic attack.
In this ( asthma ) there is airways hyperresponsiveness that is secondary to inflammatory airways disease
that results in recurrent or chronic episodes of wheeze ,shortness of breath
, chest tightness
& /or cough
particularly at the nigh or in the early morning.
Perhaps you understand that why are you having cough in the night due to cold
When such patient visit my clinic I prescribe monteleukast + bambuterole tablet once or twice in day depending upon the condition of patient and severity of disease (. symptoms )
Since this is a prescription medicine so consult your treating doctor .
Hot coffee and steam inhalation also provide relief.
Hope this will help you.
