1. What is Quadramet and what is it used for
Quadramet is a medicinal product for therapeutic use only.
This radiopharmaceutical is used for the treatment of bone pain caused by your disease.
Quadramet has a high affinity for bone tissue. Once injected, it concentrates in bone lesions. As Quadramet contains small amounts of a radioactive element, samarium 153, it delivers local radiation to bone lesions, allowing for a palliative effect on bone pain.
2. What you need to know before you use Quadramet

- If you have received chemotherapy or external hemibody radiotherapy in the 6 weeks prior to administration of the medicinal product.
Warnings and precautions
