Living with hypothyroidism? Explore treatment options >>



Hypothyroidism is a condition that develops when the thyroid gland does not make enough thyroid hormone. Thyroid hormones help control body temperature, heart rate, growth, and weight.



  • Thyroid replacement hormone is a medicine that will help bring your thyroid hormone level back to normal.

  • Take your medicine as directed. Contact your primary healthcare provider (PHP) if you think your medicine is not helping or if you have side effects. Tell him if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Follow up with your PHP or endocrinologist as directed:

You may need to return for more blood tests to check your thyroid hormone level. This will show if you are getting the right amount of thyroid medicine. Write down your questions so you remember to ask them during your visits.


The thyroid gland uses iodine to work correctly and to make thyroid hormones. Your PHP may tell you to eat foods that are rich in iodine. He will tell you which foods are good for you and how much to eat.

Contact your PHP or endocrinologist if:

  • You have a fever.

  • You have chills, a cough, or feel weak and achy.

  • You have pain and swelling in your muscles and joints.

  • Your skin is itchy, swollen, or you have a rash.

  • You have questions or concerns about your condition or care.

Seek care immediately or call 911 if:

  • Your signs and symptoms return or get worse, even after treatment.

  • You have diarrhea, tremors, or trouble sleeping.

  • Your legs, ankles, or feet are swollen.

  • You feel like you are going to faint.

  • You have a seizure.

  • You have sudden chest pain or shortness of breath.
