Just 2day I discovered that one of the main exclusion criteria for spiriva ( a long acting bronchodilator used for copd) is cystic fibrosis patients. The bad news is that I 've been on spiriva since 4 months during which my health took a huge decline and I had 4 unsuccessful tune ups. It looks like I ve been another victim of another "bad decision" to say the least from my doc. Does anyone know the amount of damage spiriva can cause to cystic fibrosis patients or have any info related to cf about this damned medication?
