How do i deal with mild asthma attacks during night thanks in advance?

First...: The first thing you need to make sure about is that you have a rescue inhaler(albuterol for example) in order to deal with events. If they are becoming very frequent you will need an inhaled steroid which will keep the inflammation associated with asthma under control. In order to get those you will need to see your doctor. If you experience significant trouble breathing you need to go to the ER.

Consult A Doctor: Asthma is a chronic disease of the airway and we can not tell you on thus site how to treat what you describe mild Asthma during night We need more information about your night time asthma like how long it has been going on,is it every night,do you cough or wheeze or get short of breath and have you been treated in the past or tried any inhalers or pills I suggest you consult your Doctor asap

Depends on cause: Not all nocturnal asthma symptoms are cause by Asthma. Other conditions like GERD, COPD, obstructive sleep apnea, heart failure can cause Nocturnal Asthma. Work with your doctor. For simple Asthma, ICS (inhaled corticosteroids) and SABAs (short acting agonists) occasionally LABAs (Long acting beta agonists) are used. Also make sure allergies are controlled. Good luck !
