My son was diagnosed at 13 (ish) with Graves Disease and put on Carbimazole and Thyroxin. His levels were good but the doctors wanted to see if the problem had sorted itself so discussed taking him off the medication. He got bored of waiting (he's 16) and so did it himself on Christmas Eve! He had a blood test at 2 weeks which showed him now as underactive and the doctor said he was to go back to the same dosage?
BUT my question is how long does it take for the medication to leave the system to show a true reading??
I spoke to a friend who is a doctor and has read up since knowing about my son and she said we should wait 6 weeks, we're nearly at week 6 now.
Any info gratefully received
