Pentacis is a radiopharmaceutical product for diagnostic use
onlyi.e. a radioactive medicine used for diagnostic purposes.
Pentacis contains pentetate which is used in combination with a
radioactive solution of technetium (99mTc) in order to form a
solution of technetium (99mTc)-pentetate.
When injected into a vein of your arm, this product temporarily
collects in the kidneys or the brain. It collects in the lungs when
inhaled and in the stomach when ingested.
Because of its radioactivity, it can be detected outside the body
using a special camera, and pictures, known as scans, can be
taken. These scans will show exactly the distribution of the
radioactivity within the organ and the body. These scans give
valuable information about the structure and/or the functioning
of the concerned organ.
Pentacis is used for:
• the detection of abnormalities in your kidneys, your lungs or
your brain, and /or,
• the evaluation of the functioning of your kidneys, brain or
Your doctor/Nuclear Medicine specialist will explain to you what
kind of examination will be performed.

Pentacis must never be used
• If you are allergic (hypersensitive) to trisodium and calcium
pentetate or any of the other ingredients of this medicine or to
any of the components of the labelled radiopharmaceutical.
These ingredients are listed in section 5.

obtained without a prescription.
Please tell your physician if you are taking, or have

they may interfere with your physician interpretation of the
• Captopril (medicine used to treat high blood pressure
• Furosemide (diuretics or “water pills”)
• Mood altering medicines.
Pregnancy and breast-feeding
You must inform the specialist physician in nuclear medicine
before the administration of Pentacis 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 physician or the
specialist physician in Nuclear Medicine who will supervise the


If you are pregnant, your physician will only consider this
examination during your pregnancy in case of absolute necessity,
because it is recommended to avoid an examination using
technetium (99mTc) during pregnancy. This might involve a risk to
the foetus.
If you are breast-feeding
Resuming breast-feeding should be in agreement with the
specialist in Nuclear Medicine who will perform the
investigation. Usually, it can be resumed 12 hours after the

Medicine who will supervise the procedure before taking any
Before Pentacis administration you should:
- drink plenty of water and to be well hydrated before the start of
the examination in order to urinate as often as possible during

Important information about some of the ingredients of
Pentacis contains 2.2 mg of sodium per vial.
Depending on the volume injected, the limit of 1 mmol (23 mg) of
sodium per dose administered may be exceeded. This must be
taken into account if you are on a low-salt diet. The Nuclear
Medicine specialist who is going to perform the examination will
be able to tell you the exact quantity of sodium injected.
The specialist physician in Nuclear Medicine supervising the
procedure will decide on the quantity of Pentacis to be used in
your case. It will be the minimal quantity necessary to get the
desired information.
The quantity to be administered usually recommended for an adult
ranges from 1.8 to 1800 MBq (MBq: Megabecquerel - the unit in
which radioactivity is measured), depending on the type of
examination and on the route of administration.
Use in children
In case of paediatric population, the quantity to be administered
will be adapted to the child’s body mass.
Administration of Pentacis and conduct of the procedure
Technetium (99mTc) pentetate is either administered by injection
into a vein of your arm, or by inhalation using a nebulizer. It can
also be swallowed as a liquid.
A single administration is sufficient to provide your physician with
the information needed.


Duration of the procedure
Your physician will inform you about the usual duration of the
procedure.The scans can be taken at any time from the beginning
of the administration, depending on the type of study which is to
be performed.
To study the functioning of your kidneys, a second set of scans
can be taken after you have been administered a medicine
(furosemide by injection or captopril orally) to help in diagnosis.
If you have been administered more Pentacis than you
An overdose is almost impossible because you will only receive a
single dose of Pentacis precisely controlled by the specialist
physician supervising the procedure. In particular, the specialist
physician supervising the procedure may recommend that you
drink abundantly in order to facilitate the elimination of Pentacis
from your body.
Should you have any further questionon the use of Pentacis,
please ask your doctor or the specialist in Nuclear Medicine
who supervises the procedure.
Like all medicines, Pentacis may cause side effects, although not
everybody gets them.
Very rare cases of allergic type reactions have been reported. The
following effects have been described :

redness of skin (flushing),
difficulty in breathing (dyspnoea),
hives (urticaria),
low blood pressure (hypotension).


Any of the above could be sign of allergy (anaphylactic reaction).
Contact a doctor immediately.
Your doctor has considered that the clinical benefit that you will
obtain from the procedure with the radiopharmaceutical
overcomes the risk due to radiation.
If you notice any of the side effects, or if you notice any side
effects not listed in this leaflet, please tell your doctor or the
specialist physician in Nuclear Medicine who supervised the
