1.What Quadramet is and what it is used for

Quadramet is a medicinal product for therapeutic use only.

This radiopharmaceutical is used for the treatment of bone pain due to your disease.

Quadramet has a high affinity for skeletal tissue. Once injected it concentrates in bone lesions. Because Quadramet contains small amounts of a radioactive element, samarium-153, radiations are delivered locally to the bone lesions, allowing to develop the palliative action on bone pain.

2. What you need to know before you take Quadramet

Do not take Quadramet:

If you are allergic to ethylene diamine tetramethylene phosphonic acid (EDTMP) or similar phosphonate compounds or any of the other ingredients of this medicine (listed in section 6),

If you are pregnant,

If you have received chemotherapy or hemibody field external radiation therapy in a preceding period of 6 weeks.

Warnings and precautions

Talk to your doctor before taking Quadramet.

Your doctor will take blood samples weekly for at least 8 weeks to check your platelets, white and red blood cell counts which may slightly decrease due to the therapy.

During 6 hours following the injection of Quadramet, your physician will encourage you to drink and void as often as possible. He will decide at which time you will be authorised to leave the nuclear medicine department.

In the case of urine incontinence or urinary obstruction you will get a urine catheter for about 6 hours. For the other patients the urine should be collected for at least 6 hours.

If your renal function is decreased, the amount of product will be adapted.

Children and adolescents

Quadramet is not recommended for use in children below 18 years of age.

Other medicines and Quadramet

Tell your doctor if you are taking or have recently taken or might take any other medicines.

Pregnancy and breast-feeding:

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.

Quadramet must not be administered to pregnant women.

If Quadramet administration to a breastfeeding woman is deemed necessary, breastfeeding should be stopped.

3.How to take Quadramet

Your doctor will want to carry out a special scan before administering Quadramet to ascertain whether you are likely to benefit from Quadramet.


One single dose of 37 megabecquerel (Becquerel is the unit in which radioactivity is measured) of Quadramet per kilogram of body weight is to be injected.

If you have the impression that the effect of Quadramet is too strong or too weak, talk to your doctor or pharmacist.

Method and route of administration

Quadramet is to be administered by slow injection into a vein.

Frequency of administration

This medicinal product is not intended to be injected on a regular or continuous basis. The administration can however be repeated after 8 weeks following injection, subject to the evolution of your disease.

Duration of treatment

You will be authorised to leave the nuclear medicine department after a dosimetric follow-up (generally within 6 hours following Quadramet injection).

If you take more Quadramet than you should

Quadramet being supplied as a single-dose vial, an accidental overdose is unlikely to occur. Radiation dose to the body can be limited by increasing fluid intake and frequent voiding of urine.

If you have any further questions on the use of this product, ask your doctor or pharmacist.

4.Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

The undesirable effects due to Quadramet administration are linked with a decrease of red and white blood cells, and platelets. Cases of bleeding have been reported, some of which have been serious.

This is the reason why your blood counts will be monitored strictly for a few weeks following Quadramet injection.

You may exceptionally feel a slight increase in bone pain a few days after Quadramet injection. You should not be alarmed at this; in such case, your pain medicine will be slightly increased. This effect is moderate and brief and will disappear after some hours.

Adverse drug reactions such as nausea, vomiting, diarrhoea and sweating were reported.

Hypersensitivity reactions including rare cases of anaphylactic reaction have been reported after Quadramet administration.

In rare cases, the following undesirable effects have been observed: neuralgia, coagulation disorders, cerebrovascular accidents. These effects were deemed to be related to the progression of the disease.

If you experience back pain or sensory abnormalities, please inform your physician as soon as possible.
