"Started using Spiriva in 2003 and noticed much improvement in breathing and endurance. As my emphysema has worsened and flare-ups occurred more frequently, my pulmonologist added Onbrez and it too is very helpful. The combination is effective for me, FEV1 went from 37% to 52%. My principal side effect is dry mouth, but a sip of water now and then beats shortness of breath or worse."
