Anyone hypothyroid and pregnant?? I *possibly* took double levothyroxine by a cudent

Really hoping someone can advise me. i'm 23 weeks pregnant and have an under active thyroid. I take my 50 micrograms of levothyroxine religiously every morning and thyroid levels have all been "normal" so far throughout pg. so far, so good.

Except today! I forgot to take it this morning so I just had a dose with lunch thinking "better late than never". Except now my paranoid brain is wondering what if I actually did take it this morning and I've just doubled up by accident!!! Trust this to happen on a weekend when there is no endocrine clinic to ring. I don't want to call NHS Direct really as I always find they tend to add to my panic in any given situation that I call them.

Anyone know anything about the levothyroxine who can advise??

I don't know how to edit my post title. It should read "by accident". Poxy ipad auto correct!!!

I think it's exceptionally unlikely that one extra tablet will do any harm - when I alter my dose of thyroxine it takes a few weeks of taking the extra every day before it makes any difference to my T4 levels. Given that it's also quite a small amount and you took it with food which will decrease the amount absorbed, I really wouldn't worry about it.

I agree, it's a very slow-working thing whenever a dose gets changed and you only did it once.
And Mrsmini is right that it's quite a low dose (though of course we don't know your situation). My young daughter is on 50/75 on alternate days and I am on 175 a day.
Yu can always ring an endocrine nurse on Monday and get your mind put at rest, too.

I wouldn't worry. Like PP said it takes a couple of weeks for levels to adjust when dose is changed. You'll be absolutely fine.
Forget about it and call GP Tuesday for a blood test if you still need reassurance.

Mrsmini - thanks for the quick reply. I did a little bit of Googling (always risky!) and did see some mention that it is very slow-absorbing and my dose is considered quite low as it is. I know food lessens absorption too.

I was completely sure I hadn't taken it this morning before I took the lunchtime dose. But as soon as I swallowed it down the doubts started creeping in!

Thanks Choccy and Deja. smile Yes I do remember my endo Dr saying to me that changes in dose take a while to take effect.

The more I think about it, the more I'm certain I am I didn't take a dose this morning. But I will leave a message for my endo clinic for next week anyway.

I'm usually so good with my meds regime!

I wouldn't worry either, a bit more levothyroxine is not going to make any difference. I'm actually surprised that you haven't had to increase your levothyroxine, because usually they find your TSH levels go up during pregnancy and you need to take more. But it's good you're with an endo clinic and they are keeping an eye on your levels.

Hi blueamber - yes I'm T1 diabetic too so I'm very well known to my endo clinic. My consultant did acknowledge that some doctors increase meds automatically with pregnancy but that she didnt feel it necessary and my levels have stayed "normal" On 50mcg. My thyroid problem was only picked up during a diabetes preconception clinic fairly recently so maybe that has something to do with my low dose not being increased? Ie The meds are relatively new to my system already?

dont worry, levothyroxin wont harm baby at all-i take 50mg, on the other hand not taking enough could.

i mean not taking enough generally might be a problem- forgetting occasionally won't.
