Thyroid Drugs in Pregnancy

Pregnancy places some limits on the treatments which a woman can receive for hyperthyroidism , because a doctor must also look out for the safety of your child. A common treatment for hyperthyroidism is radioactive iodine , but it must be avoided by women who are pregnant or nursing a baby as it may cause hypothyroidism in the baby.
Surgery to remove a goiter or cancer may also be delayed until after the pregnancy.
However, needle aspiration biopsy of a thyroid nodule may be safely done during pregnancy.
Treatments which may be used for thyroid disease during pregnancy include:

  • Antithyroid drugs , which block the production of thyroid hormone
  • Thyroid hormone pills , which provide the body with the right amount of thyroid hormone when the gland is not able to produce enough by itself.
