1. What Ceretec is and what it is used for

This medicine is a radiopharmaceutical for diagnostic use only.

It contains an active ingredient called "exametazime", which is mixed with a radioactive component called "technetium" before use. Once injected, it can be detected from outside the body by a special camera used in the examination.

Ceretec is given before an examination and, along with a special camera, helps to see inside a part of the body.

Ceretec is used for:

  • The examination can help your doctor find out how much blood is getting to your brain. This may be important to know after a stroke, a head injury, if you have fits or epilepsy, or to distinguish between Alzheimer's disease and other similar types of dementia. It can also be used to help diagnose brain death.
  • The examination can help your doctor investigate a fever of unknown origin.
  • The test can also help your doctor investigate infectious foci in your bones (osteomyelitis) or abdomen (the area around your stomach).
  • Some people will be given the medicine to look at inflammation in the intestine.

Your doctor will explain which part of your body will be examined.

Receiving Ceretec involves getting a small amount of radioactivity. Your doctor and nuclear medicine doctor have considered that the clinical benefit you will get from the procedure with the radiopharmaceutical outweighs the risk of radiation.

2. What you need to know before you are given Ceretec

Ceretec must not be used

  • If you are allergic to Ceretec or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Be especially careful with Ceretec

  • If the person to be given this medicine is a child or adolescent.
  • If you are pregnant or think you might be pregnant.
  • If you are breast-feeding.
  • If you are on a low-sodium diet.

Children and adolescents

Tell your nuclear medicine doctor if you are under 18 years old

Using Ceretec with other medicines

Tell your nuclear medicine doctor if you are taking, have recently taken or might take any other medicines, as some medicines may interfere with the interpretation of the images.

Pregnancy and breast-feeding

You must tell your nuclear medicine doctor before you are given Ceretec if there is any chance you may be pregnant, if you have a delayed period or if you are breast-feeding.

In case of doubt, it is important that you consult your nuclear medicine doctor who is supervising the procedure.

If you are pregnant

Your nuclear medicine doctor will only give you this medicine during pregnancy if the benefit is expected to outweigh the risk.

If you are breast-feeding

Do not breast-feed if you receive Ceretec. This is because small amounts of "radioactivity" may pass into breast milk. If you are breast-feeding, your nuclear medicine doctor may wait until you have finished breast-feeding before using Ceretec. If this is not possible, your doctor may ask you to:

  • stop breast-feeding for 12 hours or more
  • use formula milk to feed your child and
  • express and discard your breast milk.

Please consult your nuclear medicine doctor when you can restart breast-feeding.

Driving and using machines

Ceretec is unlikely to affect your ability to drive or use machines. Ask your doctor if you can drive or use machines after receiving Ceretec.

Ceretec contains sodiumand depending on when it is given, the sodium content may be higher than 23 mg (1 mmol), which should be taken into account in the treatment of patients on low-sodium diets.

3. How Ceretec is given

There are strict rules about the use, handling and disposal of radiopharmaceuticals. Ceretec will only be used in specially controlled areas. This product will only be handled and administered by trained and qualified personnel who are able to use it safely. These people will take special care in the safe use of this product and will inform you of their actions.

The nuclear medicine doctor supervising the procedure will decide the amount of Ceretec to be used in your case. This will be the minimum amount necessary to get the desired information.

The recommended amount to be given to an adult is usually between 555-1110 MBq for brain scintigraphy and 185-370 MBq for the in vivo localization of technetium(99mTc)-labelled leucocytes.

MBq: Megabecquerel is the unit used to express radioactivity.

Use in children and adolescents

For children and adolescents, the amount given will be adjusted according to their weight

Administration of Ceretec and performance of the procedure

Tests that will be necessary before you are given Ceretec

  • You may have a blood sample taken.

If you have had a blood sample taken, it will be mixed with a solution (which contains Ceretec and the ingredient called "technetium") which will then be given to you by injection.

  • Ceretec will always be used in a hospital or clinic
  • Ceretec will be given to you by trained and qualified personnel who will provide you with the necessary information about the procedure.

Ceretec is given by intravenous injection.

One injection is enough to perform the procedure that your doctor needs.

After the injection, you will be offered a drink and asked to urinate immediately before starting the procedure.

Duration of the procedure

Your nuclear medicine doctor will inform you about the usual duration of the procedure.

After you have been given Ceretec, you should:

Urinate frequently to eliminate the product from your body.

Your nuclear medicine doctor will inform you if you need to take any special precautions after you have been given this medicine. Consult your nuclear medicine doctor if you have any doubts.

If you have been given more Ceretec than you should

Overdose is unlikely because you will receive a single, precisely controlled dose of Ceretec from your nuclear medicine doctor. However, in case of overdose, you will receive the appropriate treatment.

If you have any further questions about the use of Ceretec, ask your nuclear medicine doctor who is supervising the procedure.
