I started back on to singulair after my last lot of blimin virus's. My peak flow never changes from 450 unless i've exercised, it can go up to 500. So its pretty good.
I only ever suffer with my asthma when i've cold a chest infection. When i think back to when i was on singulair ( i came off it 2 years ago as they think it may of caused my stomach ulcer...i don't think it did!!) i never got bad chest infections. Only until i was off the singulair. I'd be interested to find out whether it will help me in the future if (god forbid) i get a chest infection again. Especially if its an anti inflammatory. Has anybody had the same experience. I will say though i haven't had hayfever at all!!! GREAT
