If you have been taking Montral for a year and want to stop, it is usually safe to discontinue, but do not stop suddenly without checking with your doctor. Your doctor can guide you on whether you still need it or if another treatment is better.

You can continue taking Montral occasionally if it helps your dust allergy and chest congestion, but try not to depend on it daily unless your doctor advised it. Focus on avoiding dust, using a mask, steam inhalation, and staying hydrated. If symptoms keep coming back or you feel breathless, it is better to get checked once so the doctor can see if you need an inhaler or a better long-term plan instead of tablets.
