I’m going on holiday in August and planning to take Norethisterone (period delaying tablets). Does anyone know if thyroxine or the fact I’ve had a total thyroidectomy (May 2018) due to PTC will affect this?
I know that some birth control tablets can interfere with your thyroxine. However it looks like the tablet you're going to take is a progesterone one.
I believe the best thing to do - as I'm on progesterone too - is to leave at least half an hour after taking thyroxine, before taking the period delaying tablets. That way the thyroxine will be safely absorbed before the other gets in there.
