Dear Doctor, My daughter aged 15 is suffering from hypothroidism, she is on 50 mcg of thyronorm since 4 months now. She is now complaining of uneasiness and restlessness and feels very tired. Is it because of overdose ? should we reduce the dosage ? Also, we have done 3 bloodtests during this period, while her TSH and T4 are in normal range, her t3 has been coming down from 0.90 to 0.51 at the moment. Would appreciate your reply. Many thanks
