Along with its needed effects, a medicine may cause some unwanted effects. When radiopharmaceuticals are used in very small doses to study an organ of the body, side effects are rare and usually involve an allergic reaction. These effects may occur almost immediately or a few minutes after the radiopharmaceutical is given. It may be helpful to note the time when you first notice any side effect. Your doctor, nuclear medicine physician and/or technologist, or nurse will be prepared to give you immediate medical attention if needed.

Check with your doctor or nurse immediately if any of the following side effects occur:


  1. Chills
  2. difficulty breathing
  3. drowsiness (severe)
  4. fainting
  5. fast heartbeat
  6. fever
  7. flushing or redness of skin
  8. headache (severe)
  9. nausea or vomiting
  10. skin rash, hives, or itching
  11. stomach pain
  12. swelling of throat, hands, or feet

Other side effects not listed may also occur in some patients. If you notice any other effects, check with your healthcare professional.

Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.
