My 6 year old daughter was diagnosed with Graves on June 4th. She is on 15 mg of methimazole a day and propranolol 4 times a day. At first the levels were not coming down. At our last visit her T3 has moved from a 15.9 to a 7.1. We were very excited to finally see the levels coming down. If her levels are coming down, why does she demonstrate such strong Graves symptoms still...tremors, heat intolorance, eating a lot, nightmares, very moody, joint pain, staring, inability to focus..... I think the only reason the pulse rate is under control is because of the propranolol. We thought by now she should be at normal levels (we get bloodwork done next week and back to the doctor on the 13th.) School starts in a few weeks and I'm worried. Can levels go up and down to cause this?
