Patient's question:
My son has been experiencing headaches since he was five or six years old. Now he is 13, and two years ago, he stayed at a boarding school in a private school. He had many episodes of rapid heartbeat and was hospitalized for 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, saying it would shorten his bone age. He is 148 cm tall, and his hypothyroidism is now normal, so he is no longer allowed to take levothyroxine. Is this okay? Does letrozole have side effects? When should the five 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 the middle after stopping it, right? This is the first follow-up check of 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 distressed. Just follow the guidance and advice of the professional physician to implement appropriate treatment, and endure follow-up visits. Even if your thyroid function is normal, you still need to take (Thyroxine). You cannot stop the medication arbitrarily.
