Does anyone find cheaper generic versions of Montelukast affect their asthma control? My pharmacy supply different types of this drug on a regular basis. I now have what looks like a really cheap version of it (even if it should meet product licence)
For a while now my asthma control has been below normal and the only thing that is different is the Montelukast. I'm breathless, exercise tolerance is down, husky voice, waking during the night and using my ventolin more.
