What drug counters the effect of taking too much T3?

This is just an information-gaining post.

Somewhere; although I cannot now remember where.... I came across an article/paper that mentioned a prescription drug used as an "antidote" if you should take too much T3 and I was wondering if anyone knows the name(s)?

The best way, in my point of view, is to miss the next few days dose. Maybe they suggested a beta-blocker if the heart was going too fast.

Helena877,

There is no antidote to Liothyronine or thyroid hormone poisoning. You will have to wait for an overdose of Liothyronine to clear your system which will take some days. If you take too much Liothyronine drinking milk immediately after will reduce the absorption of the Liothyronine.

Whilst amiodarone can be taken for thyrotoxicosis arising from too much levothyroxine there is no drug for excess liothyronine, other than beta blockers to protect the heart. The only therapy that has been used is plasma exchange which is a major hospital process and very rarely used ncbi.nlm.nih.gov/pubmed/283... . The real answer is to take great care not to take too much T3.

Usually a beta blocker.

Not just any beta blocker - they vary. The one usually chosen is propranolol.
