My doc just told me that if my lung function was under 40 percent that spiriva doesn't do any good. I thought it was suppose to help maintain what lung function I had left. Am I just wasting my money to buy this expensive drug for nothing. Anyone know anything about it.
Yes I have COPD. Not sure of how much lung use I have left. But I know it's under 40 percent. Just not sure about this new doc saying spirivia won't slow the disease down if under 40 percent.
