Thyroid UK

21 years old, newly diagnosed hypothyroid


I've just been diagnosed the other day with hypothyroid with a TSH of 59. I've been taking 75mg of thyroxine (eutroxsig) for 3 days now. Main symptoms are fatigue, no "get up and go"/low energy, acne, low/zero libido, dry skin&hair.

I was hoping for some advice on when i can expect to feel better as i'm sick of feeling so lethargic all the time while my friends just seem to have endless energy. Also just wanting advice in general as from what i understand, this condition can take a long time to improve with adjustments in dosaging etc. (is my dose a good amount to be prescribed initially?). I'm already taking a lot of vitamins including iodine and selenium so i hope that helps and i have coeliac disease so i avoid gluten. Basically any support/advice would be very much appreciated! Thank you <3

Hi kepey, welcome to the forum.

Yes, it's a very good dose to start on. But it will take about seven days to be absorbed, and six weeks until you feel the full effects.

So, in six weeks after starting the 75 mcg, you should go back for another test. Make your appointment for early in the morning - before 9 am - and fast overnight. Just drink water. And leave 24 hours between your last dose and the test.

Did they tell you how to take levo? First thing in the morning, with a large glass of water, and wait at least one hour before eating or drinking anything other than water. Leave two hours between levo and other medications or supplements, and four hours between levo and iron, vit D and estrogene (if you take it!). And six hours between levo and magnesium.

And, talking of supplements, I'm rather concerned by what you say, there. Why are you taking iodine? Did you get tested for deficiency first? Iodine is really not a good thing to take if you don't need it. Excess iodine can cause all sorts of problems.

What else are you taking? Did you get tested for any deficiencies? Taking supplements is not just something you do on a whim, you have to know what you're doing, what to take and what not to take, how much to take, when to take it and what to take it with. So, it might be a good idea to let us have a look at all that. :)


Hi greygoose! Thank you so much for your response. I'm especially glad that you told me about taking the supplements 4-6 hours after the thyroid medication because i did not know that. Yes, luckily my doctor has done blood/urine tests to measure my levels of vit d/magnesium/zinc/selenium/iodine etc. so i'm not overdosing on anything, at least according to my latest blood tests. Thanks again!


@ kopey

Oh my!!! If you're taking thyroxine then you should stop all other supplements until you've read the small print. Iodine should not be taken along side thyroxine as far as I'm aware and neither should iron be taken at the same time. Personally there are very few herbal remedies that agree with me since I've been on thyroxine and that will be born out as a problem generally.
