How long does it take T3 to fully leave your system?

Hi

I recently went from taking levothyroxine alone to a combination of this with liothyonine (t3). Unfortunately the t3 caused an intense pounding heart so I stopped taking it.

It has been 6 days and I'm still experiencing a bit of pounding, which I never had previously with levothyroxine alone. Is this still the t3 in my system?

I know it has a half life of about 24 hours, but does anyone know how long it takes to completely leave the body/blood cells etc?

Many thanks and happy Christmas!

    Hello Sayhitocaz:

    The body takes a bit of time to FULLY clear and it can take up to 2 to weeks as long  as you take no more Liothyronine.

    Hi Again Sayhitocaz:

    The post accidently sent before I finished.  It can take 2 to 3 weeks as long as you take no more Liothyronine (cytomel).  Everyday it should go down and if only on it a short time, it may be a bit quicker.

    Hope this helps,

    Shelly

      Thanks Shelly! Yes I'm off it completely now. The heart pounding is gradually getting less so must need to wait another week or two smile xx

    I had a bad reaction to NDT at the beginning of October and think the T3 was the cause. Think it might be to do with my adrenals but that's another story. It took me around 10 weeks to feel 'normal' again. Feel fine now.
