1. What Quadramet is and what it is used for
Quadramet contains the active substance samarium (153Sm) lexidronam pentasodium.
This medicine is a radiopharmaceutical for therapeutic use only.
Quadramet is used to treat bone pain caused by your disease.
Quadramet has a high affinity for bone tissue. Once injected, it concentrates in bone lesions. Since Quadramet contains small amounts of a radioactive element, samarium (153Sm), it delivers localized radiation to the bone lesions, providing palliative relief from bone pain.
Administration of Quadramet involves receiving a small amount of radioactivity. Your doctor and the nuclear medicine physician have determined that the clinical benefit you will receive from this radiopharmaceutical procedure outweighs the risk associated with radiation exposure.
2. What you need to know before using Quadramet
Do not use Quadramet:
- If you are allergic to samarium (153Sm) lexidronam pentasodium or to similar phosphate compounds or to any of the other components of this medicine (listed in section 6),
- If you are pregnant or think you might be pregnant,
- If you have received chemotherapy or hemibody radiotherapy within the previous 6 weeks.

3. How to use Quadramet
There are strict regulations regarding the use, handling, and disposal of radiopharmaceuticals. Quadramet will only be used in specially controlled areas. This product will only be handled and administered by trained and qualified personnel competent to use it safely. These individuals will take special care in the safe use of this product and will inform you of their actions.
The nuclear medicine physician supervising the procedure will decide the amount of Quadramet to be used in your case. This will be the smallest quantity necessary to achieve the desired effect.
The generally recommended dose for administration in an adult is 37 MBq per kg of body weight (MBq: megabecquerel, the unit used to express radioactivity).
Administration of Quadramet and performance of the procedure
Quadramet must be administered by slow intravenous injection.
This medication is not administered on a regular or continuous basis. However, administration may be repeated after 8 weeks from the last injection, depending on the progression of your disease and whether your blood counts have recovered after the previous treatment.
Duration of treatment
Your nuclear medicine physician will inform you about the usual duration of the procedure.
After administration of Quadramet, you should:
- avoid close contact with young children and pregnant women during the 48 hours following the injection
- urinate frequently to eliminate the product from your body. The nuclear medicine physician will inform you when you will be discharged from the hospital. In case of urinary incontinence or urinary obstruction, a urinary catheter will be placed for approximately 6 hours.
Your physician will take weekly blood samples for at least 8 weeks to monitor your platelet and red and white blood cell counts, which may decrease slightly due to the treatment.
The nuclear medicine physician will inform you if you need to take any special precautions after receiving this medication. Consult your nuclear medicine physician if you have any doubts.
If you have been given more Quadramet than you should have
An overdose is unlikely, as you will receive a single dose of Quadramet precisely controlled by the physician supervising the procedure.
However, in the event of an overdose, appropriate treatment will be administered.
If you have any further questions about the use of Quadramet, ask the nuclear medicine physician supervising the procedure.
