<s>[INST] I am taking montek lc and singular 250 montec 1 per night 250 2 puffs morning and night I stay controlled for long periods of time but when I travel the asthma flares I am trying doubling the montec one day one night but still as soon as I exert myself I cant breathe well when under control I never have to use puffer its frustrating to have it under control for so long then get flare ups just when I need to feel good to enjoy my life [/INST] Hellos you mentioned that you are taking Monte LC and singular 250. Previously asthma was under control, but symptoms aggravate during travelling. When such asthmatic patient visit I advise them to take montelukast+albuterol combination because this time you require some potent bronchodilator. Montelukast will act an anti allergen, while albuterol will act as bronchodilator. In the beginning you may feel some fine skeletal tremor but Chat Doctor. From first dose you will get relief in your asthmatic attack. Hot coffee and steam inhalation also provide relief. Hope this will help you. Good luck. </s>
