Talk to your prescriber or health care professional before taking any of these over-the-counter medicines:
Tell your prescriber or health care professional about all other medicines you are taking, including non-prescription medicines, nutritional supplements, or herbal products. Also tell your prescriber or health care professional if you are a frequent user of drinks with caffeine or alcohol, if you smoke, or if you use illegal drugs. These may affect the way your medicine works. Check with your health care professional before stopping or starting any of your medicines.
You must visit you prescriber or health care professional regularly for periodic blood tests to monitor your condition and the effects of strontium-89 treatment. If your pain increases or returns, contact your prescriber or health care professional.
The effects of strontium-89 are limited to within your own body. Other people will not be harmed by coming into contact with you. You may eat and drink normally after receiving strontium-89.
For several days after the injection, strontium-89 will be present your urine. To help protect you and others, certain steps need to be taken for week after receiving the injection. Whenever possible, use a toilet rather than a urinal, and flush several times after each use. Any spilled urine should be cleaned up completely, and you should wash your hands thoroughly. If any blood or urine gets onto your clothing, wash those clothes separately.
Within 2—3 days of your injection, you may feel a slight increase in pain, chills or fever that may last for 2—3 days. You should begin to notice a decrease in your pain within 2 weeks. This should continue and last up to 6 months. Depending upon your response, you may be able to decrease the amount of other pain medicines you are taking. Do not stop taking any medication without consulting with your prescriber or health care professional.
Strontium-89 may cause a slight decrease in your platelet and white blood cells. These should return to normal 6—8 weeks after your injection. Notify your prescriber or health care professional if you notice increased bruising, bleeding or blood in your urine or stools.
Unless instructed to by your prescriber or health care professional, avoid taking aspirin, acetaminophen (Tylenol®), ibuprofen (Advil®), naproxen (Aleve®), or ketoprofen (Orudis® KT) products as these may mask a fever or increase your risk to bleed if you have low white blood cell or platelet counts.
You should use an effective method of birth control and avoid breast-feeding while receiving this drug.
You should tell any other health care professional providing you with medical care that you have received treatment with strontium-89.
The side effects you may experience with strontium-89 therapy depend upon the dose, other types of chemotherapy or radiation therapy given, and the disease being treated. Not all of these effects occur in all patients. Discuss any concerns or questions with your prescriber or health care professional.
