1. What is Thyrogen and what is it used for
Thyrogen contains the active substance thyrotropin alfa. Thyrogen is a human thyroid-stimulating hormone (TSH) produced by biotechnology processes.
Thyrogen is used for the detection of certain types of thyroid cancer in thyroidectomized patients maintained on thyroid hormones. One of the effects is that it stimulates any remaining thyroid tissue to take up iodine, which is important for imaging with radioactive iodine. It also stimulates the production of thyroglobulin and thyroid hormones if there is any residual thyroid tissue. These hormones can be measured in the blood.
Thyrogen is also used with radioactive iodine treatment to eliminate (ablate) remaining thyroid tissue after surgical removal of the thyroid gland (remnants) in patients who do not have secondary growths (metastases) and who are receiving thyroid hormone.
2. What you need to know before you start using Thyrogen
Do not use Thyrogen:
- if you are allergic to bovine or human thyroid-stimulating hormone (TSH) or to any of the other ingredients of this medicine (listed in section 6).
- if you are pregnant.
Warnings and precautions
Talk to your doctor or pharmacist before starting Thyrogen:
- if you have kidney disease that requires dialysis; your doctor will decide how much Thyrogen to give you, as you may be more likely to suffer from headache and nausea.
- if your kidney function is reduced; your doctor will decide the amount of radioactive iodine to be given.
- if your liver function is reduced; you can still receive Thyrogen.
Effect on tumor growth
In patients with thyroid cancer, cases of tumor growth have been reported during withdrawal of thyroid hormones for diagnostic procedures. This was thought to be related to elevated levels of thyroid-stimulating hormone (TSH) for a longer period. It is possible that Thyrogen may also cause tumor growth. This was not seen in clinical trials.
Due to the elevation of TSH levels after administration of Thyrogen, patients with secondary tumor growth (metastases) may experience local swelling or bleeding at the site of these metastases, which may increase in size. If metastases are present in confined spaces, e.g. intracerebral (in the brain) or in the spinal cord, patients may experience symptoms that can manifest rapidly, such as partial paralysis affecting one side of the body (hemiparesis), respiratory problems, or loss of vision.
Your doctor will decide if you belong to one of the specific patient groups where prior treatment with corticosteroids should be considered (e.g. if you have secondary tumor growth in the brain or spinal cord). If you have any doubts, consult your doctor.
Children
Due to the lack of data on the use of Thyrogen in children, Thyrogen should only be given to children in exceptional circumstances.
Elderly
No special precautions are necessary for elderly patients. However, if the thyroid gland has not been completely removed and you also suffer from heart disease, your doctor will help you decide whether you should receive Thyrogen.
Other medicines and Thyrogen
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
No drug interactions are known with Thyrogen and thyroid hormones that you may be taking.
Your doctor will determine the exact activity of radioactive iodine to be used for imaging, taking into account the fact that you continue to take thyroid hormones.
Pregnancy and breastfeeding
Do not take Thyrogen if you are pregnant. If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.
Thyrogen should not be administered to breastfeeding women. Breastfeeding should not be resumed until your doctor tells you to do so.
Driving and using machines
Some patients may feel dizzy or have headaches after administration of Thyrogen that may affect their ability to drive and use machines.
Thyrogen contains sodium
This medicine contains less than 23 mg of sodium (1mmol) per vial; this is essentially "sodium-free".
3. How to use Thyrogen
A doctor or nurse will inject your medicine.
Your treatment should be supervised by a doctor with experience in thyroid cancer. The Thyrogen powder must be dissolved in water for injectable preparations. Only one vial of Thyrogen is required per injection. Thyrogen should only be administered in the buttocks. This solution should never be injected into a vein. Thyrogen should not be mixed with other medicines in the same injection.
The recommended dose of Thyrogen consists of two doses administered with a 24-hour interval between them. Your doctor or nurse will inject 1.0 ml of the Thyrogen solution.
For ablation or imaging with radioactive iodine, your doctor will administer the radioactive iodine 24 hours after the last injection of Thyrogen.
The diagnostic scan should be performed 48 to 72 hours after administration of the radioactive iodine (72 to 96 hours after the last injection of Thyrogen).
The post-treatment scan may be postponed for a few days to allow the general radioactivity to decrease.
For thyroglobulin (Tg) analysis, your doctor or nurse will take a serum sample 72 hours after the last injection of Thyrogen.
Use in children
Your child's doctor will help decide whether Thyrogen should be given to your child.
If you use more Thyrogen than you should
Patient who received too much Thyrogen by accident have described nausea, weakness, dizziness, headache, vomiting, and flushing.
In case of overdose, treatment to restore fluid balance, as well as administration of an antiemetic, is recommended.
If you have any further questions on the use of this product, ask your doctor.
