Another approach to the prognosis of cough-variation asthma is to look if the cough responds to anti-asthmatic treatment. Doctors regularly propose a bronchodilator spray which include albuterol (Proventil, Ventoline). It's short performing. So, further your physician would possibly prescribe an inhaled cortico steroid, consisting of fluticason (Flovent), triamcinolone (Azmacort) or budesonide (Pulmicort).
