You should look for natural treatment of asthma. I read a book called asthma free naturally as written by Patrick McKeown. That this book is available online and details the Buteyko breathing method for asthma. He teaches Buteyko Breathing Clinic and many other methods. Have a look at asthmacare ie Asthma Care Ireland- Featured on RTE and TV3, Buteyko Clinics and books You would surely be benefited.
