What is Thyrogen injection?
Thyrogen injection is a brand of synthetic human Thyrotropin (also called recombinant TSH, or “thyrotropin alfa”). It is used to raise thyroid-stimulating hormone (TSH) levels in the body so that certain radioactive iodine tests and treatments work effectively, even when the patient is not producing its own TSH at high levels. It is given as an injection by a healthcare professional.
What is it used for?
Thyrogen injection is used in two main settings involving thyroid cancer care and follow-up:
- Helping doctors find or evaluate thyroid cancer recurrence by supporting radioactive iodine diagnostic scanning.
- Supporting radioactive iodine therapy for selected thyroid cancer patients, by making the cancer’s thyroid tissue more responsive to the iodine treatment.
How does Thyrogen work?
Thyrogen (recombinant TSH) increases TSH levels without requiring patients to stop their thyroid hormone medication for a long period. Higher TSH can stimulate any remaining thyroid cancer cells (or thyroid tissue) to take up radioactive iodine, which improves the effectiveness of the test or treatment.
How is Thyrogen given?
Thyrogen is administered as an injection (intramuscular use is commonly described for thyroid hormone stimulation approaches). The exact timing and number of doses depend on whether it is being used for a diagnostic scan versus treatment, and on the specific protocol your care team follows.
Why do people use Thyrogen instead of stopping thyroid medicine?
Many radioactive iodine scans or treatments traditionally require patients to reduce thyroid hormone production (often by stopping levothyroxine) to drive up TSH naturally. Thyrogen can raise TSH without that withdrawal period, which may help some patients avoid the symptoms that can occur when thyroid hormone levels drop.
