Fluticasone / vilanterol
"I've had asthma since I was about four (now fourty) and it's been terrible. Mostly triggered by allergies. Been on every cortico you can think of. I'd go through three rescue inhalers a month.  I've been on Breo for about four months and have had two rescue inhalers filled.  I can exercise withought using it, I can sleep at night and I have gone days with completely forgetting I had a rescue inhaler.  It has been a miracle drug.  It is expensive though but my doctor gave me a discount card and it's free now.  My only issue is when its very cold and you work your bronchi hard outside, it hurts but it's worth it.  Also you can build an immunity to it and it starts to not work as well after the four or five months.  BUT it still works well."
