I'm a 56 year old male who has been taking 500/50 Advair since it came out - about 9 years ago or so. Having severe asthma since my mid-twenties, this medication has been the best for me than anything else, and has greatly limited my dependency on prednisone and has kept my general well-being fairly stable. I always try to cut back when I'm breathing better, but have never been able to skip more than one day before asthma symptoms begin to come back. So far, I have notice no side effects! Anyone know what's up with that? Also, I've tried everything under the sun to naturally get away from all medications, but have never been even close to successful....but I'm still looking.
