Hi all I am aware that most people on this site will have little knowledge about the drug Amiodarone so here is a brief account of what it is used for and it's potential side effects that can alter conversion of thyroid medication such as levo or NDT so pushing levels either up or down. It can also effect thyroid function (levels) of a person who does not take any thyroid medication at all, hence thyroid levels can also go up or down This medication is iodine based so it is quite toxic to the thyroid and many other parts of the body but as this is a thyroid site I will stick to thyroid issue only. Another point to mention: The half life of this medication is said to be 6months according to some medical doctors while others, ie, my endocrinologist reports that the iodine can stay in the body for years at a time. This medication is used to treat AFib which is the reason why I was prescribed it on 17 April.
At that time I was on 75/50 levo alternate days. Thyroid tests were always ok. After taking Amiodarone for 7 weeks began to experience hyper thyroid symptoms. Test revealed T4 was over range. GP reduced levo to 50mcg daily. I also reduced Amiodarone from 200mcg to 100mcg daily. Honestly believed reduction of both meds would make a difference. Repeat test 8 weeks later despite reductions T4 still over range. In fact on comparing previous blood test there was virtually no difference at all in the results. Hence endocrinologist reduced levo to 25mcg daily which is my present dose of levo. Furthermore, I stopped taking Amiodarone altogether when levo was reduced (8wks ago) for the second time. Will this make a difference? I suspect it wont. Do believe the lengthy half life of Amiodarone will still push the small levo dose over range.
Furthermore, have had no AFib attacks since stopping Amiodarone which could also indicate it is still present in my body due to the extensive half life of the drug.
I still have hyperthyroid symptoms, anxiety, hyper active, always on the go, sweating a lot, unable to relax, always thinking what can I do now. Rise in BP. Today I am exhausted....kinda burnt out, did not sleep at all last night.
Anyway getting private blood test via Medichecks on Tuesday morning an will be surprised if T4 is within range. Let's hope it is in range if it is not in range dread to see how much further levo will be reduced.
What do you guys think? Really would appreciate some feedback. I have been pencilled in for maze procedure in Sheffield to treat AFib in November an really concerned that thyroid issue and hyper status could set the date back. Whoops after this procedure the standard treatment is Amiodarone....!
