Radiopharmaceuticals for Pain Relief from Metastatic Bone Disease

Your doctor has recommended radiopharmaceuticals (RAY-dee-oh-far-muh-SUE-tuh-kols) to treat your bone pain. A radiopharmaceutical is a radioactive drug that is given through an injection in your arm. Once injected, the medication travels through your body and settles in your bones, giving you relief from pain.

Your radiopharmaceutical injection will be done as an outpatient procedure. The injection will take only a few minutes, after which you may go home. You may continue your normal daily activities with friends and family members after your injection. Pain relief usually occurs within seven to 10 days after the injection.

Relief may last from three to six months or more. Your doctor may repeat the injection every 90 days if your blood counts are stable. Continue taking your current pain medication. You and your doctor will decide if the dosage needs to be adjusted.  A bone scan must be done within 3 months of the  injection. 

Precautions

Because radiopharmaceuticals are removed by the kidneys through your urine, there are some precautions you will need to take:

  • Before your injection, you will be asked to drink about two cups of fluid. For the first 24 hours after your injection, it is important to empty your bladder frequently.
  • For the first 12 hours after your injection, it is important to use a toilet when possible, rather than a urinal or bedpan. Flush the toilet twice after each use.
  • If urine is spilled, the area should be cleaned completely, and you must wash your hands with soap and water.
  • Clothing stained with your blood or urine should be washed separately or stored separately for one to two weeks before washing with your regular load of laundry.
  • If you are sexually active, it is strongly advised that you use an effective method of birth control for 30 days after your injection. Speak to your doctor or nurse if you have questions about birth control methods.

Possible Side Effects

Increased bone pain may occur for the first week following your injection. This pain is usually controlled with the pain medication that has been ordered by your doctor.

  • A drop in your red blood cells and platelet counts may occur. Your doctor may monitor your blood counts weekly for up to three months after your injection. It is important to follow your doctor’s instructions for your blood work and to keep any follow-up appointments.  We will give you a prescription for regular blood counts to be drawn.
