Northisterone and levothyroxine. Should they be taken at same time?

[emmylou71]

Hiya. I've recently started taking northisterone for endometriosis but since have been feeling totally exhausted. I'm currently on 50 mcg since 2005 when I was diagnosed but recently feeling like my brain is in a fog and extremely cold. Any ideas or help would be great!!

First of all I would suggest you get a new thyroid gland blood test from your GP and get a copy from your surgery, with the ranges, and post on a new question for members to comment.

Do not take levo on the morning of the blood test, take if afterwards. Also ask for a Vitamin B12, Vitamin D, iron, ferritin and folate to be done. 50mcg is quite a small dose (although it may suit some people) but as you have clinical symptoms I think you need an increase.

I would suggest that other medications/supplements should be taken about 4 hours apart from Levo so that there is no interactions.

Thanks for both your replies. I'm seeing the doctor on 20th do will ask about blood tests then. I've always taken thyroxine before each one so shall try not taking it next time. Also taking other tablets later in day so fed up of feeling lethargic!
