1. WHAT IS METAJODOBENZYLOGUANIDYNA- I (MIBG- I) FOR THERAPY AND
WHAT IS IT USED FOR
Metajodobenzyloguanidyna- I (MIBG- I) for therapy is a radiopharmaceutical that contains
the active substance, the radioactive isotope iodine-131. The preparation is administered intravenously in
doses of varying radioactive activity for therapeutic purposes.
Iodine [I] is a short-lived radioisotope with a half-life of 8.04 days.
Metajodobenzyloguanidyna- I (MIBG- I) for therapy is a radiopharmaceutical used in
cancer therapy. Therapeutically, MIBG- I is used to treat disseminated metastatic lesions of malignant pheochromocytoma, paraganglioma, neuroblastoma,
ganglioneuromas, and sometimes medullary thyroid cancer.
2. IMPORTANT INFORMATION BEFORE USING

When not to use Metajodobenzyloguanidyna- I (MIBG- I) for therapy?
If the patient is allergic to jobenguan (I)or any of the other ingredients of this medicine
(listed in section 6).
An absolute contraindication to the use of the preparation is:
- hypersensitivity to the active substance or to any of the excipients,

- bone marrow damage,
- unacceptable medical risk associated with the need for patient isolation,
- severe cases of urinary incontinence.
The product contains benzyl alcohol: 10 mg/ml, so it should not be administered to premature infants
or newborns.
Warnings and precautions
Due to the risk of radiation exposure, caution should be exercised when treating patients with
radioactive iodine who:
- may not follow the recommendations of medical staff,
- have urinary incontinence.
Some patients receiving high activities of iodine-131 may need to be hospitalized due to the need to comply with radiological protection regulations.
Administering drugs containing radioactive isotopes poses a risk of exposure to external ionizing radiation or contamination caused by urine stains, vomiting, etc. to other people. Therefore, basic hygiene rules should be followed.
To reduce the radiation dose absorbed by the bladder, it is recommended to drink a bit more fluid than average (about 1-1.5 liters per day more) and to empty the bladder more frequently after administration of the medicine.
