question: Hi Doc, I have been using Asthalin inhaler for about 20 years now. I used to use it once a week or 10 days or on emergency. But for the past two years the number of times I get breathing difficulty have increased and am was using Asthalin once every 1- 2 days. Very recently I am forced to use it repeatedly at least 4-5 times a day for the past 3-4 months. I have been also having cold and cough for the past 3 weeks now. One doctor suggested that I start using Montek LC everyday. 2 tabs a day. I am worried if it would have any side effects. Should I continue using Montek LC forever or should I stop it after I get relief?
