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

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

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

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

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