1. What Gastrografin is and what it is used for
Gastrografin is a contrast medium (a dye) which contains iodine. It
is used to clearly show on X-rays the area of your body that your
doctor wants to investigate. This will be your gullet (oesophagus),
stomach or intestines (gastrointestinal tract). It may also be used
to treat an intestinal obstruction in newborn babies (meconium
X-rays, like radio waves, can pass through objects and can be focused
to make a picture. When you have an X-ray, the beam of rays goes
through your body where it is absorbed to differing degrees by
different tissues such as bones, muscles and organs. When the rays
come out on the other side they make a pattern of light and shade
on a film. Gastrografin helps to make this pattern clearer. The film is
then examined by a specialist who will make a diagnosis.
This medicine is for diagnostic use only.

2. What you need to know before you are given Gastrografin
Do not use Gastrografin:
R if you are allergic to sodium amidotrizoate, meglumine
amidotrizoate, iodine or iodine-containing contrast media or any
of the other ingredients of this medicine (listed in section 6)
R if you have a condition caused by too much thyroid hormone
(manifest hyperthyroidism).
Warnings and precautions
Talk to your doctor or the X-ray department staff/radiologist before
receiving Gastrografin
You must tell the X-ray department staff if you have any of the
R any type of thyroid disease (e.g. hyperthyroidism)
R a history of allergy or a tendency to develop hypersensitivity
reactions (for example if you have hay fever, asthma or eczema)
R heart or blood circulation problems, because in the rare event
that you have an allergic reaction, it is more likely to be serious
or fatal.
Gastrografin may affect the way the thyroid gland works for
several weeks after being given it. If you are going to have an iodine
test for thyroid disease, tell your doctor or the laboratory staff if
you have received Gastrografin recently.
Other medicines and Gastrografin
Tell your doctor or the X-ray department staff/radiologist if you are
taking, have recently taken or might take any other medicines. This
is particularly important for:
R beta-blockers (drugs used to treat heart or blood pressure),
because they can make allergic reactions worse
R if you have been treated with a drug called interleukin, because
there is a higher chance of getting delayed reactions (e.g. fever
flu-like symptoms, joint pain and pruritus (itching)).
Ask the X-ray department staff if you are not sure.
Gastrografin with food and drink
Before the examination the X-ray department staff should make sure
that you have had enough to drink and that any imbalances in your
body water and body salts are corrected.

The following information is intended for healthcare professionals
Information for Healthcare Professionals

1 ml solution contains: 100 mg sodium amidotrizoate (sodium
diatrizoate) and 660 mg meglumine amidotrizoate (meglumine
Excipients with known effect: disodium edetate, sodium hydroxide,
saccharin sodium
For the full list of excipients, see section 6.1.

Gastroenteral solution

4.1 Therapeutic indications
This medicinal product is for diagnostic use by oral or rectal
administration only.
Gastrografin is a contrast medium for the radiological examination
of the gastrointestinal tract (also in combination with barium
Gastrografin may be of particular value in the following instances:
1. Suspected partial or complete stenosis.
2. Acute haemorrhage.
3. Threatening perforation (peptic ulcer, diverticulum).
4. Other acute conditions which are likely to require surgery.
5. After resection of the stomach or intestine (danger of
perforation or leak).
6. Megacolon.
7. Visualisation of a foreign body or tumour before endoscopy.
8. Visualisation of a gastrointestinal fistula.
9. Before Endoscopy.
Further indications:
R Early diagnosis of a radiologically undetectable perforation or
anastomotic defect in the oesophagus.
R The treatment of uncomplicated meconium ileus.
R Computerised tomography in the abdominal region.
4.2 Posology and method of administration
Dosage for oral use
The dosage is dependent on the type of examination and the age of
the patient.
Adults and children of 10 years of age or over:
Visualisation of the stomach: 60 ml
Follow-through examination of the gastrointestinal tract: a
maximum of 100 ml
Computerised tomography (CT)
0.5 - 1.5 litres of approximately 3% Gastrografin solution (30 ml
Gastrografin/1 litre of water).
Older and cachectic patients: Dilution with an equal volume of
water is recommended.
Children (up to 10 years of age): 15-30 ml (can be diluted with
twice its volume of water)

Infants and young children: 15-30 ml (diluted with 3 times its
volume of water)
Dosage for rectal use (including therapy of uncomplicated meconium
Up to 500 ml Gastrografin dilution (diluted with 3 - 4 times its
volume of water)
Children (over 5 years of age): up to 500 ml Gastrografin dilution
(diluted with 4 - 5 times its volume of water)
Children (up to 5 years of age): up to 500 ml Gastrografin dilution
(diluted with 5 times its volume of water)
Therapy of uncomplicated meconium ileus
Gastrografin can be given by enema for non-operative treatment of
uncomplicated meconium ileus. Advantage is taken of the high
osmotic pressure of the contrast medium: the surrounding tissue is
forced to release considerable amounts of fluid, which then flows
into the gut and dissolves the inspissated meconium.
The procedure must be carried out slowly and only under
fluoroscopic control. Injection should stop as soon as Gastrografin
is seen to enter the ileum. Owing to its high osmolarity,
Gastrografin may cause the loss of a large amount of fluid into the
intestines. An intravenous drip must therefore be set up before the
enema is given and fluid should be infused as required. If the
Gastrografin is not expelled during the first hour after removal of the
rectal catheter, an X-ray should be taken to ensure that
overdistension of the bowel as a result of the high osmolarity of
Gastrografin has not occurred.
Dosage for Gastrografin in combination with barium sulphate: Oral
and rectal administration.
In adult patients, addition of approximately 30 ml Gastrografin to
the usual dose of barium should be adequate.
Children from 5 - 10 years of age: 10 ml Gastrografin to 100 ml
barium sulphate suspension.
Children up to 5 years of age: 2 - 5 ml Gastrografin to 100 ml barium
sulphate suspension.
If necessary (in cases of pylorospasm or pyloric stenosis), the
portion of Gastrografin in the suspension may be further increased.
This does not affect the contrast.
For the early diagnosis of a perforation or investigation of an
anastomosis in the oesophagus or gastrointestinal tract, the
patient should drink up to 100 ml Gastrografin. After 30-60
minutes (later, if the defect is suspected of being in the distal gut),
a urine specimen should be taken and 5 ml mixed with 5 drops of
concentrated hydrochloric acid. The contrast medium which has
undergone renal excretion will appear within two hours as a typical
crystal formation in the precipitate.
4.3 Contraindications
Hypersensitivity to iodine-containing contrast media. Manifest
Gastrografin must not be administered undiluted in patients with
low plasma volume, as for example in newborns, infants, children
and in dehydrated patients, since hypovolaemic complications can
be particularly serious in these patients.

Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or
are planning to have a baby, ask the doctor or X-ray department
staff /radiologist for advice before receiving this medicine.
Gastrografin contains sodium
This medicinal product contains 3.8 mg sodium per ml. To be taken
into consideration by patients on a controlled sodium diet.

3. How you will be given Gastrografin
The X-ray department staff will explain how everything works and
what position you should lie in on the X-ray table.
The dose of Gastrografin and how it will be given will depend on
the type of investigation. The dose range is usually from 2 ml to
125 ml Gastrografin. This may be diluted depending on the type of
Gastrografin is either drunk as a solution or given as an enema, a
liquid that is forced by low pressure into the anus. It must not be
given by injection into the blood vessels.
If you receive more Gastrografin than you should
Overdosing is unlikely. If it does happen the radiologist will treat any
symptoms that follow.
If you have any further questions on the use of this medicine, ask
your doctor or the X-ray department staff/radiologist for advice
before receiving this medicine.

4. Possible side effects
Like all medicines, this medicine can cause side effects, although
not everybody gets them.
If you notice:
R itching of the skin, rash, wheals on the skin (urticaria)
R difficulty breathing, gagging, feeling of suffocation
R swelling of the face, neck or body
R itchy or watery eyes, tickling in the throat or nose, hoarseness,
coughing or sneezing
R headache, dizziness, feeling faint
R feeling particularly hot or cold, sweating
R paleness or reddening of the skin
R chest pain, cramp, tremor
R feeling sick
Tell the radiologist or X-ray staff immediately as these may be the
first signs of allergic reaction or shock. Your investigation will need
to be stopped, and you may need further treatment.

Please turn over J
Gastrografin must not be administered undiluted in patients with
suspected possibility of aspiration or broncho-oesophageal fistula,
since hyperosmolarity may cause acute pulmonary oedema,
chemical pneumonia, respiratory collapse and death.
4.4. Special warnings and precautions for use
The following risks are higher in the case of intravascular
administration of iodinated contrast media but are also relevant
for the enteral use of Gastrografin.
As with other contrast agents, Gastrografin can be associated with
anaphylactoid/hypersensitivity or other idiosyncratic reactions,
characterized by cardiovascular, respiratory or cutaneous
manifestations, and ranging to severe reactions including shock.
Delayed reactions may occur (hours later or up to several days) (see
section 4.8).
Medication for the treatment of hypersensitivity reactions as well
as readiness for institution of emergency measures are necessary.
The risk of anaphylactoid/hypersensitivity reactions is higher in
case of:
R any history of allergic disorders,
R history of bronchial asthma,
R a previous anaphylactoid/hypersensitivity reaction to iodinated
contrast media.
Patients with cardiovascular disorders are more susceptible to
serious or even fatal outcomes of severe anaphylactoid/
hypersensitivity reactions.
Gastrografin contains sodium
This medicinal product contains 3.8 mg sodium per ml. To be taken
into consideration by patients on a controlled sodium diet.
Barium sulphate
If Gastrografin is used together with barium sulfate preparations,
attention must be drawn to the contraindications, warnings and
possible side effects relevant to the preparation.
In case of prolonged retention of Gastrografin in the
gastrointestinal tract (e.g. obstruction, stasis), tissue damage,
bleeding, bowel necrosis and intestinal perforation may occur.
Adequate hydration and electrolyte balance should be established
and maintained in the patients, since the hyperosmolarity of
Gastrografin may cause dehydration and electrolyte imbalance.
Because of the additives (flavourings and a wetting agent),
Gastrografin must not be used intravascularly.
4.5 Interaction with other medicinal products and other forms
of interaction
Hypersensitivity reactions can be aggravated in patients on betablockers.
Interleukin-2: Previous treatment (up to several weeks) with
Interleukin-2 is associated with an increased risk of delayed
reactions to Gastrografin.
Interference with diagnostic tests
Radioisotopes: Diagnosis and treatment of thyroid disorders with
thyrotropic radioisotopes may be impeded for up to several weeks
after administration of iodinated contrast agents due to reduced
radioisotope uptake.
4.6 Fertility, pregnancy and lactation
Adequate and well-controlled studies in pregnant women have not
been conducted.
Animal studies do not indicate direct or indirect harmful effects
with respect to embryonal/foetal development (see section 5.3).
Caution should be exercised when using Gastrografin in pregnant

Apart from the symptoms listed above the other side effects that you
might experience are:
R feeling sick or being sick
R diarrhoea
R anaphylactic shock (a very severe allergic reaction)
R allergic-type skin reactions including itching, redness, wheals on
the skin
R overactive thyroid gland (hyperthyroidism)
R disorder of your body water and body salts balance
R fainting, dizziness, headache
R fast heart beat, sudden stopping of the heart (cardiac arrest),
low blood pressure, shock
R difficulty breathing, swelling or fluid in the lungs. If Gastrografin gets into your lungs by accident it may cause fluid to collect
in your lungs
R abdominal pain, holes in the gut wall (intestinal perforation)
R blistering inside the nose or mouth
R severe skin disease (red, blistered, bleeding, painful skin, which
may affect the lips, eyes, mouth, nose and genitals too)
R rash, redness of the skin
R swelling of the face
R fever, sweating
If you currently have inflammation of the intestine or bowel
(enteritis or colitis), this may temporarily get worse. If you currently
have a blockage in your bowel, this can lead to Gastrografin
staying in the bowel for longer than usual, which may damage the
lining of the bowel.
Delayed reactions can occur, if you are concerned you should contact
your doctor.
Reporting of side effects
If you get any side effects, talk to your doctor, radiologist or X-ray
department staff. This includes any possible side effects not listed in

4.9 Overdose
Disorders of water and electrolyte balance caused by overdose
should be corrected.

5.1 Pharmacodynamic properties
Pharmacotherapeutic group: X-ray contrast media, iodinated and
watersoluble, ATC code: V08AA01
Gastrografin does not exert a pharmacological effect. It is an iodine
containing contrast medium, iodine being radio-opaque.
5.2 Pharmacokinetic properties
Only 3% of amidotrizoic acid, the radio-opaque agent of
Gastrografin, is absorbed following oral administration. If a
perforation of the gastrointestinal tract is present, Gastrografin finds
its way into the abdominal cavity or the surrounding tissue, where it
is absorbed and finally excreted via the kidneys.
5.3 Preclinical safety data
Non-clinical data reveal no special hazard for humans based on
conventional studies of systemic toxicity, genotoxicity, toxicity to
reproduction, local tolerance and contact-sensitizing potential.

6.3 Shelf life
Shelf life (unopened): 5 years
Shelf life (opened): 72 hours
6.4 Special precautions for storage
Protect from light and X-rays. Store below 25 °C.
6.5 Nature and contents of container
Packs of 10 x 100 ml brown glass bottles with pilfer proof screw
6.6 Special precautions for disposal and other handling
At temperatures below 7 ºC Gastrografin tends to crystallize, but this
can be reversed by gently warming and shaking the bottle. This
phenomenon has no effect on the effectiveness or stability of the
Contrast medium solution not used within 72 hours after opening
