Patient's question:
My son has been experiencing headaches since he was five or six years old. Now he is 13, almost 18. Two years ago, when he stayed at a private boarding school, he had many episodes of rapid heartbeat and was hospitalized for suspected myocarditis, receiving intravenous fluids. In August 2018, it was discovered that he had hyperthyroidism, and he took many medications for it. On September 5th, a follow-up test revealed hypothyroidism. Now his condition is normal, and the frequency of his headaches has significantly decreased. Today, he had an MRI, and the doctor asked what the problem was. The doctor prescribed letrozole to shorten his bone age. He is 148 cm tall, and his hypothyroidism is now under control, so he is no longer taking levothyroxine. Is this okay? Does letrozole have side effects? When should his thyroid function tests be rechecked? Should he still be taking levothyroxine?Doctor's answer:
I want to understand first that if you have hypothyroidism, you haven't taken any medication in between after stopping the medication, is that correct? This is the first follow-up check for thyroid function. If that's the case, and your thyroid function is normal, then the medication for hypothyroidism may not need to be taken for the time being. In this situation, you don't need to worry or be overly troubled. Just follow the guidance and suggestions from professional physicians to implement appropriate treatment, and endure follow-up visits. Even if your thyroid function is normal, you still need to take (Levothyroxine), and you cannot stop the medication arbitrarily.
