This medicine contains the active substance radium Ra 223 dichloride (radium-223 dichloride).
Xofigo is used to treat adults with advanced castration-resistant prostate cancer in progression after at least two other cancer treatments apart from treatments to maintain reduced levels of male hormone (hormone therapy), or who cannot take any other cancer treatment. Castration-resistant prostate cancer is a cancer of the prostate (a gland of the male reproductive system) that does not respond to treatment that reduces male hormones. Xofigo is only used when the disease has spread to the bone but is not known to have spread to other internal organs, and is causing symptoms (e.g., pain).
Xofigo contains the radioactive substance radium-223 which mimics the calcium found in bones. When injected into the patient, radium-223 reaches the bone where the cancer has spread to and emits short-range radiation (alpha particles) which kills the surrounding tumour cells.
Talk to your doctor before you are given Xofigo
Your doctor will test your bone health before deciding whether you can be given Xofigo. During treatment and for 2 years after starting treatment with Xofigo, your doctor will continuously monitor your bone health.
This medicine is not for use in children and adolescents.
No interaction studies with other medicines have been done.
Xofigo must not be given in combination with abiraterone and prednisone/prednisolone due to a possible increase in the risk of bone fracture or death. Additionally, there are uncertainties about the effects of Xofigo in combination with other systemic medicines used to treat metastatic prostate cancer. If you are already taking one of those medicines, please tell your doctor.
If you take or have taken bisphosphonates or other medicines to protect your bone health or steroids (e.g., prednisone/prednisolone) prior to treatment with Xofigo, please tell your doctor. You might be at a higher risk for bone fractures.
If you are taking calcium, phosphate and/or Vitamin D, your doctor will carefully consider if you need to temporarily stop taking these substances before you start treatment with Xofigo.
There are no data on the use of Xofigo at the same time as chemotherapy (other medicines used to kill cancer cells). Xofigo and chemotherapy used together may further decrease the number of your blood cells and blood platelets.
Tell your doctor if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription.
Xofigo is not for use in women and must not be given to women who are, or may be, pregnant or who are breast-feeding.
If you are engaged in sexual activity with a woman who could become pregnant you are advised to use effective birth control methods during and up to 6 months after treatment with Xofigo.
There is a potential risk that radiation from Xofigo could affect your fertility. Please ask your doctor how this may affect you, especially if you are planning to have children in the future. You may wish to seek advice on conservation of sperm before treatment starts.
It is considered unlikely that Xofigo will affect your ability to drive or to use machines.
Depending on the volume administered, this medicine can contain up to 54 mg sodium (main component of cooking/table salt) per dose. This is equivalent to 2.7% of the recommended maximum daily dietary intake of sodium for an adult.
There are strict laws on the use, handling and disposal of medicines like Xofigo. It will only be used in special controlled areas. This radiopharmaceutical will only be handled and given to you by people who are trained and qualified to use it safely. These persons will take special care for the safe use of this radiopharmaceutical and will keep you informed of their actions.
The dose you receive depends on your body weight. The doctor supervising the procedure will calculate the quantity of Xofigo to be used in your case.
The recommended dose of Xofigo is 55 kBq (Becquerel, the unit used to express radioactivity) per kilogram body weight.
No dose adjustment is necessary if you are 65 years of age or older or if you have reduced kidney or liver function.
Xofigo will be injected slowly via a needle into one of your veins (intravenously). The healthcare professional will flush the intravenous access line or cannula before and after injection with a sodium chloride solution.
An overdose is unlikely.
However, in the case of an accidental overdose, your doctor will start appropriate supportive treatment and will check you for changes in the number of blood cells, and for gastrointestinal symptoms (e.g. diarrhoea, nausea [feeling sick], vomiting).
If you have any further questions on the use of Xofigo, please ask the doctor who supervises the procedure.
Like all medicines, this medicine can cause side effects, although not everybody gets them.

Your doctor will perform blood tests before starting treatment and before each injection to check your number of blood cells and platelets (see also section 2).
The most frequent side effects in patients receiving Xofigo (very common [may affect more than 1 in 10 people]) are:
Risk of dehydration: tell your doctor if you have any of the following symptoms: dizziness, increased thirst, decreased urination or dry skin as these can all be symptoms of dehydration. It is important to avoid dehydration by drinking plenty of fluids.

Xofigo contributes to your overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure may increase your risk of developing cancer (in particular of bone cancer and leukaemia) and hereditary abnormalities. No cases of cancer caused by Xofigo have been reported in clinical studies with a follow-up of up to three years.
If you have symptoms of pain, swelling or numbness of the jaw, a “heavy jaw feeling” or loosening of a tooth, please contact your doctor. Cases of osteonecrosis of the jaw (dead tissue in the jawbone which is mainly seen in patients who have been treated with bisphosphonates) have occurred in patients treated with Xofigo. All these cases were only seen in patients receiving bisphosphonates prior to or at the same time of treatment with Xofigo and chemotherapy prior to treatment with Xofigo.
