Is it safe during pregnancy?Thyroid hormone affect the unborn baby?Pls ans, Thanks in advance [/INST] Hi, Thyroxine is harmless to the baby and in fact prevents hypothyroidism in developing fetus. Continue with 50 mcg of thyroxine. Do not change the dose often. Continue with the low dose and give time for your body to adjust to the hormone levels. Check your thyroid levels every 20 days until it maintains a normal value. Hypothyroid patients should continue thyroxine in pregnancy. Higher doses such as double dose can be required to be taken. Take care. Hope I have answered your question. Let me know if I can assist you further.  </s>
