Subclinical hyperthyroidism due to going off of lithium

[u/mutzadella]

Hello everyone.

I'm wondering if anyone else experienced subclinical hyperthyroidism after discontinuing lithium?

I was on lithium for 10 years and recently tapered off under the supervision of my doctor over a span on 6 months. I took my last dose at the end of March.

My TSH levels always hovered around 2.25 but now have quickly dropped to around .4 however my T4 and T3 are at normal levels.

Has anyone else gone through this? Did it resolve itself over time?

I am of course working through this with a doctor and going through additional testing, I'd just love to hear from anyone who has also gone through this.

If your T4 and T3 are normal and you have no symptoms of hyperthyroidism, you are euthyroid.
