I think I have too high a dose (500) - esp as this is the first medication I have had for what is presumed to be COPD (spirometry normal, but junior registrar thinks it looks like COPD).
Anyhow - side effects, on one puff every 12 hours: CRAMP, BAD HEADACHE, HEAVY FEELING, FALLING ASLEEP (at home), feeling extremely tired, feeling very depressed,
i have been on it for over a week now, and think i am going to take it once every 24 hours, like Warren below! 500 seems a bit OTT esp for somebody who is 67, as the first drug of choice- esp as not experiencing breathlessness YET.
