What is Thyrogen (thyrotropin alfa)?

Thyrotropin alfa is a manmade form of a protein similar to thyroid-stimulating hormone (TSH), which is normally produced by your thyroid. Thyrotropin alfa keeps your TSH levels steady while you undergo thyroid tests or treatments that can reduce TSH and cause symptoms of low thyroid (hypothyroidism).

Thyrotropin alfa is used together with radioactive iodine ablation (a procedure to remove thyroid tissue that was not removed with surgery) in people with thyroid cancer.

Thyrotropin alfa is also used during medical testing to check for certain types of thyroid cancer that has returned after treatment. Thyrotropin alfa may not help your doctor find all signs of cancer, and there is still a chance that some of your cancer could be missed.

Thyrotropin alfa will not treat cancer that has spread to other parts of the body.

Thyrotropin alfa may also be used for purposes not listed in this medication guide.

What is the most important information I should know about Thyrogen (thyrotropin alfa)?

Carefully follow your doctor's instructions about the timing of your medications, scans, and other treatments. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

Uses For Thyrogen

Thyrotropin alfa injection is a form of human thyroid stimulating hormone (TSH). It is used with or without radioactive iodine imaging to test the presence of thyroglobulin (Tg) in patients with thyroid cancer.

Thyrotropin alfa is also used with radioactive iodine to remove any remaining diseased thyroid tissue in patients with thyroid cancer who have had most or all of their thyroid gland removed.

This medicine is to be given only by or under the immediate supervision of your doctor.
