Hello there we umdertsand your concern towards your mother and we appreciate it. Tuisnsuffering if yiur mother is especially while seasonal changes and espsoure to dust all these may be the sign of allergy and this we have assumed based in the meeication she has taken ans she got relived of it. So this may under control for now but it may be severe one day and to aviud tha day to come all you need to do is to avoid her exposure to what all things she is allergic to so that the allergy wont be severe. Thank you
