I am taking 100 thyroxine at night and although a lot of my symptoms have improved I am concerned during the night I have night sweats

[Shahrzad]

Keeping me up all might. Could this be due to not enough meds or the side effect to Levo. I'd be grateful for any advice the kind people here can give me.

Sharzad, can you post your recent thyroid bloods results with lab ref ranges otherwise members won't be able to advise whether your sweats may be due to under or over medication. You might also say whether you are pre or post menopause as night sweats are often a symptom of menopause.

I haven't found that levo has caused me to have night sweats. In my case I think they are caused by adrenal issues, which is not uncommon with thyroid disease. But as Clutter has said it would be good to see your test results so that people can comment.

I too take 100 micrograms of levothyroxine at bed time. I felt that with Mercury Pharma product there was a tendency to feel rather warm around two hours after taking it. But, by the evening, I felt I was running out. With Actavis I had no such feeling but felt permanently under-dosed.

Have switched to German makes - Henning or Aliud. Feel fine on both. But this is not really the proper answer - it is crazy that I even decided to try them.

Who told you to take levothyroxine at night? I always take it first thing in the morning, a half hour at least before food. Everything I have ever read, including manufacturers instructions, have said to take it that way. The thyroxin isn't time released so if you take it in the morning you get maximum benefit. Plus take on an empty stomach before food so you get maximum absorption. Don't take at the same time as calcium or iron tablets either as they'll affect absorption.

Some people have always taken it at bed-time. There have been a few recent (last few years) research papers which endorse it as an option.

See the comments here:

It certainly doesn't suit all - but that is what the whole of the thyroid world of about - the extraordinary range of people and the ways in which that affects what is best for them.

I find that I sleep far better than I used to before starting.

The quality of the patient information leaflets is pretty poor. I don't think I'd trust them to be updated in a decade even if it were proved beyond all doubt that some alternative approach was better than what they have written.

I'd go a lot further than saying to separate from iron and calcium - a huge range of substances (foods, drinks, other medicines and supplements) affect levothyroxine absorption.

Hello Shahrzad. I take 125mg thyroxine just before bed and it doesn't cause sweating or dreams. Sweating is a symptom of the Menopause. If you have that at all. Afraid I don't know any other course.

[Peacefullbliss]

I get night sweats when my adrenals are low, iron is low or hormones are off. Any of these could be the cause of your night sweats. I took Levo at night and still now take NDT at night. Taking your Levo at night is not the cause.

Thank you everyone for your kind replies. I am post menopause. My test results:

No ranges given

- started on 100 mcg thyroxine on 14th Feb 2014 with test results on 17th March of FT4 20.7, TSH: 5.13, feeling ill.

- 7th April 2014 test results of FT4 20.1, TSH 1.60 reduced to 75 Levo on 12th April, feeling better.

- 12th May test results of FT4 17.4, TSH 14.3, symptoms reappeared & feeling ill. switched to taking levo at night and alternating 75 & 100 mcg Levo.

-21st May 2014 test results of FT3 3.94, FT4 15.5, TSH 19.10, Vitamin D 61, feeling ill.

Since 29th May taking 100 mcg Levo at night with 400 vit D daily. Feeling better but night sweats and disturbed sleep. This was the first time FT3 & vitamin D were included in the blood test as I insisted with the G.P but he refused to do the other tests suggested here.

These test results are what were given to me. All variations in Levo dose as advised by my Endo doctor.

I feel taking Levo in the evening suits me better than when I was taking it in the morning. The night sweats and disturbed sleep is due to my TSH being high, what do people think please.

Shahrzad, it is really unusual to have that much fluctuation in your TSH. I can't imagine why that would happen. I have been posting these short videos that bring out the complexities of treating Hashimoto's. There are 22 different causes but I'll post two that might give you an idea.

Thank you so much Heloise
