Treatment with radium-223 dichloride

Radium-223 dichloride was developed for treating metastases of prostate cancer in the bone. Radium-223 dichloride is administered as an injection in the vein. To achieve an optimal effect with minimal side effects, this is performed six times. The period in between injections is approximately four weeks, depending on your blood tests.

Advantages:

• Prolonged lifespan
• Fewer side effects from cancer in the bone (bone pain, bone fractures)

Preparation for treatment

Drink plenty of fluids before and after each injection.

After the treatment

Most of the injected radioactive substance will be expelled in the stool. A small amount of the radioactive substance will be expelled in the urine. For this reason, take the following hygienic precautions for seven days:

• Urinate in a sitting position or use a urinal to prevent splattering.
• Flush twice after each time you use the toilet.
• For the first seven days after the treatment, only use disposable materials that you can flush down the toilet after using to wipe up spots of bodily fluids (blood, vomit, urine and stool).
• Carefully wash your hands with water and soap each time you use the toilet. All other persons who use the same toilet must also wash their hands after each time and after every time they have contact with the patient's bodily fluids as listed above.
• If you are incontinent, specifically with stool incontinence, use diapers, pads or incontinence underwear that you can flush in the toilet. Dry yourself carefully to prevent contamination.

By following the instructions above, you can minimise radiation exposure to other people. No other precautionary measures are required for the contact you have with other people, including your partner. The only exception is with pregnant women and small children (blue box).

The treatment with radium-223 has no negative influence on your daily activities.

Please inform your attending physician and other physicians involved in your care that you are receiving treatment with radium-223. With this information, you can decide which treatment is the most appropriate for you. Show your treament card to all physicians and nurses who are involved in your care. This card contains all contact information for your nuclear medicine specialist and help other physicians or governmental institutions ask necessary questions (with your permission).
