Hello,
I had a total thyroidectomy due to Graves Disease on the 6th of September. I was due to get my period on the 16th that month and I missed it which was normal to me.
This month my period still hasn’t arrived and I only had the tiniest spotting.
Before surgery I would get my period every month.
My thyroid levels are still not in range and my dose is being adjusted.
Does anyone know how long this will take to get back to normal.
Many thanks .
How much levothyroxine are you currently taking
Which brand of levothyroxine
Many people find different brands are not interchangeable
Important to test vitamin D, folate, ferritin and B12 levels too
Are you currently taking any vitamin supplements
Normally bloods are retested 6-8 weeks after any dose change or brand change in levothyroxine
ALWAYS test thyroid levels early morning and last dose levothyroxine 24 hours before test
Helpful to add your age and country on your profile
I’m currently taking 75mcg Teva,
I started off with 100mcg Mercury Pharma, which was given to my abroad.
After 4 weeks I did a blood test here in the U.K. and took my Levothyroxine before my blood test which my doctor said I shouldn’t from now on. Then I was reduced from 100mcg to 75mcg and the U.K. prescribed me Teva brand.
I am currently taking multivitamins, my vitamin D, folate, b12 all look good in the blood test.
I am 25 years old and from the U.K.
What were thyroid results on 100mcg dose levothyroxine
How long after starting on levothyroxine was this test
was test done early morning, ideally around 9am
Multivitamins are never recommended on here
Most contain iodine not recommended for anyone on levothyroxine
Please add most recent vitamin results and ranges
Approx how much do you weigh in kilo
Teva brand levothyroxine upsets many people
Teva is only brand that makes 75mcg tablets
Teva contains mannitol as a filler, which seems to be possible cause of problems. Teva is the only brand that makes 75mcg tablet. So if avoiding Teva for 75mcg dose ask for 25mcg to add to 50mcg or just extra 50mcg tablets to cut in half
But for some people (usually if lactose intolerant, Teva is by far the best option)
Glenmark or Aristo (100mcg only) are lactose free and mannitol free. May be difficult to track down Glenmark, not been available very long
Most easily available (and often most easily tolerated) are Mercury Pharma or Accord
Mercury Pharma make 25mcg, 50mcg and 100mcg tablets
Accord only make 50mcg and 100mcg tablets
Accord is also boxed as Almus via Boots, and Northstar 50mcg and 100mcg via Lloyds ....but Accord doesn’t make 25mcg tablets
beware 25mcg Northstar is Teva

Once you find a brand that suits you, best to make sure to only get that one at each prescription.
Watch out for brand change when dose is increased or at repeat prescription.
Government guidelines for GP if you find it difficult/impossible to change brands
gov.uk/drug-safety-update/l...
If a patient reports persistent symptoms when switching between different levothyroxine tablet formulations, consider consistently prescribing a specific product known to be well tolerated by the patient.

Physicians should: 1) alert patients that preparations may be switched at the pharmacy; 2) encourage patients to ask to remain on the same preparation at every pharmacy refill; and 3) make sure patients understand the need to have their TSH retested and the potential for dosing readjusted every time their LT4 preparation is switched (18).
Levothyroxine is an extremely fussy hormone and should always be taken on an empty stomach and then nothing apart from water for at least an hour after
Many people take Levothyroxine soon after waking, but it may be more convenient and perhaps more effective taken at bedtime

No other medication or supplements at same as Levothyroxine, leave at least 2 hour gap.
Some like iron, calcium, magnesium, HRT, omeprazole or vitamin D should be four hours away
(Time gap doesn't apply to Vitamin D mouth spray)
If you normally take levothyroxine at bedtime/in night ...adjust timings as follows prior to blood test
If testing Monday morning, delay Saturday evening dose levothyroxine until Sunday morning. Delay Sunday evening dose levothyroxine until after blood test on Monday morning. Take Monday evening dose levothyroxine as per normal
Similarly if normally splitting your levothyroxine as two smaller doses waking and bedtime, take whole daily dose 24 hours before test
REMEMBER.....very important....stop taking any supplements that contain biotin a week before ALL BLOOD TESTS as biotin can falsely affect test results - eg vitamin B complex
