Medication change... question!

Some background info first: Even though my levels are "normal numbers", 2.25 is actually too much for myself (no period, fatigue, etc - mother was the same way) and when I am around 1.11 I am best! (get my period on a timely basis, no more fatigue, better vision, etc)

Anyway, I have been on .05mg Levothyroxine for about 7-8 months (level was 1.11) and then period stopped coming, fatigue, etc so I got it checked last month and it was at 1.33 (mine needs to be around 1.11) so the doctor put me on .025mg Levothyroxine instead to get me back to 1.11... does this sound right?

If I was at 2.25 before meds and then after taking .05mg I was at 1.11, then had it travel to 1.33... shouldn't I be taking half a mg more, not less to get it back to 1.11? I am very confused... Period still is not showing up, etc. It just does not make sense why my dosage would go down if its higher...?

That doesn't make any sense to me at all. The higher the dosage, the lower your TSH should go. Did you question your doctor about this? If not, I would call and talk to him or her to see what their logic is regarding this decision.

Your TSH level fluctuates throughout the day because the hormones released by your thyroid are released in 'spurts' rather than a continuous stream, so the amount of TSH in your system responds to the fluctuating quantities of T3 and T4 (thyroid). A difference of two tenths of a point for your TSH is not going to make you lose your period. I'm not a doctor, but I guarantee that any competent endicrinologist will agree with my statement.

And yes, it makes zero sense why your doctor halved your dose rather than adding more- they might have made a simple human error, or perhaps they intended for you to take the .025 in addition to the .05 and failed to communicate it to you?

If you're not seeing a specialist, you might want to find one. On the bright side, it sounds like you're really close to finding the perfect dose that works for you...it can takes many months/years for thyroid patients to acheive that! :-)
