Question
My child started experiencing headaches at around 5 to 6 years old and is now 13 years old. They were previously hospitalized due to tachycardia and diagnosed with myocarditis. In August 2018, they were diagnosed with hyperthyroidism and took various medications. On September 5, a re-examination showed a decrease in thyroid function. The current situation has stabilized, and the frequency of headaches has significantly decreased. A recent MRI revealed a certain condition, and the doctor prescribed Letrozole tablets, claiming it could slow down bone age growth. The child is 148 centimeters tall, thyroid function has returned to normal, and they are no longer taking Levothyroxine. Is this okay? Are there any side effects of Letrozole tablets? When should thyroid function be re-checked? Do we still need to continue taking Levothyroxine?
Answer
For hypothyroidism, if medication has not been taken again after discontinuation, this is the first thyroid function re-examination. If thyroid function has returned to normal, there is no need to continue taking medication for hypothyroidism treatment. In this situation, you do not need to be overly worried or troubled. Just follow the professional doctor’s guidance, receive appropriate treatment, and regularly return for check-ups. Even if thyroid function is normal, it is important to continue taking Levothyroxine and not to discontinue medication arbitrarily.
