I took my first dose of Spiriva respimat yesterday and it made me feel ill. I had breathing problems and a terrible headache all day. Must admit i was anxious about taking it. Anyway today i took my second dose and with in 20 minutes i got the headache again. My doctor said this inhaler doesn't cause headaches well i never suffered before. Now im scared of this inhaler. Do side effects disappear after a while or will i always suffer whilst taking this. I cant get any help from my Dr so feel all alone.
