Does anyone know how long it takes for an increased dose of thyroxine to kick in?
I've been on thyroxine for around 13 years and have been taking 175mcg for almost 10 years. This has been upped to 200mcg a week ago due to TSH of 5.5. I'm feeling completely rubbish - exhausted, in pain, dizzy spells and really low. Had to take time off work today as just physically couldn't bring myself to go. I've also been diagnosed with polycystic ovaries in the past week.
From reading posts on here seems I should have been on an increased dose for a while - my annual check in August TSH was 3.5.
