@macmurf I was on this until 10 days ago and was taken off as it suppressed my natural HR of mid 40s down to below 30. I had been on 200mg daily for 2 months to that point. I’m awaiting an ablation for flutter on 9-8. I did experience constipation and no appetite while taking. Happy to be off due to iodine content. There are other drugs to replace this though I’m on nothing now and other than the occasional skipped beat I’m doing good. I believe many experience side effects.

@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.
