@macmurf I am also one of the 1% who cannot take amiodarone. I had breathing issues within 2 weeks and a PFT test at 3 weeks showed a 41% decrease in lung diffusion. There is no remedy for the damage amiodarone did to my lungs in that 3 week period. I am a very active 81 yr old and walk 1 1/2 miles on a hilly path. I rest frequently and hope the walking will help my lungs. I don't understand why amiodarone is still used.
