How to Use This Medicine:
- Your doctor will prescribe your exact dose and tell you when it should be given. This medicine can be given different ways, depending on what part of your body the doctor needs to see. This medicine may be given through a needle or catheter (plastic tube) placed in one of your veins.
- A nurse or other health provider will give you this medicine.
- You will be given this medicine before the test. Some tests can be done right away. For other tests, you might have to wait because the diagnostic agent needs time to get to the correct parts of your body. Your caregiver should tell you how much time there needs to be between giving you the medicine and doing the test.
- Ask your caregiver if you should or should not eat or drink before the test.
- You might be given other medicines along with the diagnostic agent. Tell your doctor if you cannot use a narcotic medicine.
- Make sure your caregiver knows if you are having any other tests. You might need to wait if you are having another medicine for another test.
- Ask your caregiver if you should drink extra fluids for the next 4 to 6 hours after the test, so you will pass more urine. This will prevent the exposure of your bladder from the risks of radiation.
- Sometimes the radioactive part of this medicine will leave your body in your urine. If this is true for the medicine you are using, your caregiver should give you special instructions. Carefully follow all instructions from your doctor. You might have to flush the toilet twice after you go to the bathroom. Use a tissue to wipe up blood or urine spills, then flush the tissue down the toilet. Wash your hands with soap and water after you use the toilet or clean up urine and blood spills. If blood, urine or stools soil the clothing, the clothing should be washed separately.
Drugs and Foods to Avoid:
Ask your doctor or pharmacist before using any other medicine, including over-the-counter medicines, vitamins, and herbal products.
- Make sure your doctor knows if you have used meperidine (Demerol®) or morphine (OxyContin®, Roxanol®) recently.
