1. What TEKTROTYD is and what it is used for
This medicine is a radiopharmaceutical product for diagnostic use only.
It is used to make images of specific cells in the stomach, bowel and pancreas such as:
• abnormal tissue or
• tumours
The use of TEKTROTYD does involve exposure to small amounts of radioactivity. Your doctor and the nuclear medicine doctor have considered
that the clinical benefit that you will obtain from the procedure with the
radiopharmaceutical outweighs the risk due to radiation.
2. What you need to know before TEKTROTYD is used
TEKTROTYD must not be used
if you are allergic to HYNIC-[D-Phe1, Tyr3-octreotide] TFA salt, to EDDA
(Ethylenediamine-N,N’-diacetic acid) or to any of the excipients of this
medicine (listed in section 6) or to sodium pertechnetate (99mTc) solution
for injection.
Warnings and precautions
Take special care with TEKTROTYD
• if you are pregnant or believe you may be pregnant
• if you are breast-feeding
• if you are diagnosed with kidney failure
If any of the above information applies to you, please tell your nuclear
medicine doctor.
Before administration of TEKTROTYD
In order to obtain the best image quality adequate patient preparation
before administration of radiopharmaceutical is required.
Unless your doctor tells you otherwise, a light diet is recommended two
days before the examination.
Your doctor may recommend the administration of laxatives on the day
preceding the examination.
On the day of the examination fasting should continue until the recording
of the first pictures is completed.

Other medicines and TEKTROTYD
A number of drugs can adversely affect the outcome of the planned investigation. It is therefore recommended to discuss with the referring
physician, which intake should be discontinued before the investigation
and when the medicinal products should be taken again.
Tell also your nuclear medicine doctor if you are taking, have recently
taken or might take any other medicines, since they may interfere with
the interpretation of the images.
Pregnancy and breast-feeding
You must inform the nuclear medicine doctor before the administration
of TEKTROTYD if there is a possibility you might be pregnant, if you
have missed your period or if you are breast-feeding.
When in doubt, it is important to consult your nuclear medicine doctor
who will supervise the procedure.
If you are pregnant
The nuclear medicine doctor will only administer this product during
pregnancy if a benefit is expected which would outweigh the risks.
If you are breast-feeding
Please ask your nuclear medicine doctor when you can resume breastfeeding.
Driving and using machines
There are no studies on the effects of TEKTROTYD on the ability to drive
and use machines.
It is considered unlikely that TEKTROTYD will affect your ability to drive
or to use machines.
TEKTROTYD contains sodium
This medicinal product contains less than 1 mmol sodium (23 mg) per
vial, i.e. essentially ‘sodium-free’.
3. How TEKTROTYD is used
There are strict laws on the use, handling and disposal of radiopharmaceutical products. TEKTROTYD will only be used in special controlled
areas. This product will only be handled and given to you by people
who are trained and qualified to use it safely. These persons will take
special care for the safe use of this product and will keep you informed
of their actions.
The nuclear medicine doctor supervising the procedure will decide on
the quantity of TEKTROTYD to be used in your case. It will be the smallest quantity necessary to get the desired information.
The quantity to be administered usually recommended for an adult
ranges from 370 MBq to 740 MBq (megabecquerel, the unit used to
express radioactivity).
Administration of TEKTROTYD and conduct of the procedure
After radiolabelling the drug is administered as a single intravenous injection. This product is not intended for regular or continuous administration.
After injection you will be offered a drink and asked to urinate immediately preceding the test.
Duration of the procedure
Your nuclear medicine doctor will inform you about the usual duration
of the procedure.
After administration of TEKTROTYD, you should
urinate frequently in order to eliminate the product from your body.
The nuclear medicine doctor will inform you if you need to take any special precautions after receiving this medicine. Contact your nuclear medicine doctor if you have any further questions.

If you have been given more TEKTROTYD than you should
An overdose is unlikely, because you will only receive a single dose of
TEKTROTYD precisely controlled by the nuclear medicine doctor supervising the procedure. However, in the case of an overdose, you will
receive the appropriate treatment increasing the elimination of the radionuclide from the body, e.g. by administration of liquids and frequent
bladder voiding.
Should you have any further question on the use of TEKTROTYD,
please ask the nuclear medicine doctor who supervises the procedure.
