R Keep this leaflet. You may need to read it again.
R If you have any further questions, ask the doctor giving you
Gastrografin (the radiologist) or the X-ray department staff
R If any of the side effects gets serious, or if you notice any side
effects not listed in this leaflet, please tell your doctor or the
X-ray department staff/radiologist.

2. Before you are given Gastrografin
Do not use Gastrografin if:
R you are, or suspect you are, allergic (hypersensitive) to iodine or
iodine-containing contrast media or any of the other ingredients
of Gastrografin (see Section 6: Further Information)
R you have a condition caused by too much thyroid hormone
(manifest hyperthyroidism).

Take special care with Gastrografin:

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)

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
This medicine is for diagnostic use only.

Gastrografin may affect the way the thyroid gland works for
several weeks or more 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.
Taking or using other medicines
Please tell the radiologist or X-ray department staff if you are
taking or have recently taken any other medicines, including
medicines obtained without prescription. 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)).

Pregnancy and breast-feeding
Tell the X-ray department staff if you are pregnant or breastfeeding or think you may be pregnant.

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 2ml 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.

4. Possible side effects
Like all medicines, Gastrografin can cause side effects, although
not everybody gets them.
If you notice:

itching of the skin, rash, wheals on the skin (urticaria)
difficulty breathing, gagging, feeling of suffocation
swelling of the face, neck or body
itchy or watery eyes, tickling in the throat or nose, hoarseness,
coughing or sneezing
headache, dizziness, feeling faint
feeling particularly hot or cold, sweating
paleness or reddening of the skin
chest pain, cramp, tremor
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.

Ask the X-ray department staff if you are not sure.
Using 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.

1ml solution contains: 100mg sodium amidotrizoate (sodium
diatrizoate) and 660mg meglumine amidotrizoate (meglumine
For excipients, see 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).
Elderly 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 ileus)

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 100ml
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.
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.
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 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:
X feeling sick or being sick
X diarrhoea
X anaphylactic shock (a very severe allergic reaction)
X allergic-type skin reactions including itching, redness, wheals on
the skin
X overactive thyroid gland (hyperthyroidism)
X disorder of your body water and body salts balance
X fainting, dizziness, headache
X fast heart beat, sudden stopping of the heart (cardiac arrest),
low blood pressure, shock
X 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
X abdominal pain, holes in the gut wall (intestinal perforation)
X blistering inside the nose or mouth
X severe skin disease (red, blistered, bleeding, painful skin, which
may affect the lips, eyes, mouth, nose and genitals too)
X rash, redness of the skin
X swelling of the face
X 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.
If any of the side effects gets serious, or if you notice any side
effects not listed in this leaflet, please tell your doctor or the X-ray
department staff/radiologist.

It is unknown whether sodium amidotrizoate or meglumine
amidotrizoate are excreted in breast milk. Intravascular use has
shown that salts of the diatrizoic acid are excreted in breast milk. A
decision on whether to continue / discontinue breast-feeding or
continue / discontinue therapy with Gastrografin should be made
taking into account the benefit of breast-feeding to the child and
the benefit of administering Gastrografin to the woman.
4.7 Effects on ability to drive and to use machines
None known.
4.8 Undesirable Effects
Undesirable effects in association with the use of iodinated
contrast media are usually mild to moderate and transient in nature.
However, severe and life-threatening reactions as well as deaths
have been reported.
Vomiting, nausea and diarrhoea are the most frequently recorded
The following undesirable effects have been recorded in association
with the use of Gastrografin. The most appropriate MedDRA term is
used to describe a certain reaction and its synonyms and related
Immune system disorders, anaphylactic reaction/hypersensitivity
Anaphylactoid shock, anaphylactoid / hypersensitivity reaction.
Systemic hypersensitivity is mostly mild and occurs generally in the
form of skin reactions. However, the possibility of a severe
hypersensitivity reaction cannot be entirely excluded (see section

5.1 Pharmacodynamic properties
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.
