I was on Amiodarone for just under a year. I was prescribed it after receiving a biventricular pacemaker. I had experiended continuous Ventricle Tachycardia during the surgery.
Amiodarone is an amazingly effective drug for the treatment of arrhythmias. It also has some fairly significant side effects. I think I may have experienced all of them, including worsened hypothyroidism (but not lung issues) , during the time I was taking the drug.
I was on the standard (in North America, anyway) maintenance dosage of 200 mg, daily. I was taken off the medication when I could no longer tolerate the side effects.
But, because of ongoing SVTs, both sustained and non-sustaned varieties I am now experiencing, I may have to go back on the medication, at least for a short duration. If that happens, I will be asking to be put on the lowest dose possible.
My advice to you is to ask the lowest possible dosage - 100 mg. or lower if possible. In Europe and Britain, 100mg. is the maintenance dosage used, not 200 mg. In studies, 100 mg. has proven to be as an effective dose as the 200. You can always titrate up, if need be.
Please remember that my experience with this medication may not be yours. We are all individuals. But do give it serious consideration. All of the side effects I experienced were resolved after I stopped taking the medication.
All the best.
