Product Summary

Conray™ 280 Injection


Active substance: Iotalamic acid BP 45.6% w/v

Iodine containing contrast media may be hazardous in patients
with hyperthyroidism or with autonomous areas of the thyroid
gland. One should also be aware of the possibility of inducing
transient hypothyroidism in premature infants receiving contrast

For excipients, see 6.1.





Extravasation of the contrast material may lead to serious
tissue injury including ulceration and compartment syndrome,
depending on the volume distributed. Surgical measures may be
required to control tissue damage after large-volume extravasation.

Therapeutic indications
This medicinal product is for diagnostic use only. X-ray contrast
medium used for the opacification of vascular and renal systems
and female genital tract. It does not normally possess any
pharmacological action.



Acute renal failure has been associated with lactic acidosis in
patients receiving metformin at the time of an X-ray examination
involving parenteral administration of iodinated contrast media.
Therefore, in diabetic patients taking metformin, if the serum
creatinine is normal, the examination should be performed and
intake of metformin stopped from the time of the examination.
The use of metformin should not be resumed for 48 hours,
and should only be restarted if renal function/serum creatinine
remains within the normal range.

Posology and method of administration
Route of administration: By intravenous, intra-uterine or intraarterial injection or injection directly into the chamber of the heart,
depending on the procedure.



Intravenous urography

Adults: 40 - 80 ml
In the absence of preliminary
dehydration 40 - 100 ml may be used.
Infants and children:
Under 12 kg: 2 ml/kg body weight.
Over 12 kg: 1.5 ml/kg. Minimum of
24 ml.

The literature reports that patients who had been treated with
interleukin may develop a higher rate of adverse reactions as
described in the section “Undesirable Effects”. The reason has
not yet been clarified. According to the literature an increased or
delayed occurrence of these reactions within a period of 2 weeks
was observed after administration of interleukin.

Cerebral angiography
(carotid and vertebral)

15 - 20 ml injected into the femoral
or iliac artery will provide excellent
visualisation of the arterial tree of
leg. A similar or smaller dose is
indicated for smaller arteries.
Average adult dose is 6 - 10 ml for
each injection. Exceptionally up to
10 injections of 8 ml each have been
made into the carotid artery.

Abdominal aortography
(direct puncture or
retrograde catheterisation)

Adults: 20 - 30 ml

Thoracic aortography

Often adequate in children. 0.5 - 1 ml/kg
body weight may be used as a test
dose in positioning catheter tip.

Angio cardiography

May be used as a test dose in
positioning catheter tip.
Volumes of up to 20 ml have
been used for this purpose prior
to the diagnostic dose of more
concentrated medium.


Adults: 20 - 40 ml

Femoral venography
Inferior vena

Adults: 20 - 60 ml


About 10 ml are usually required,
administered by slow injection
into the uterine cervical canal via a
syringe or suitable cannula.



Effects on ability to drive and use machines
No effect on the ability to drive or operate machines is known.
However, due to the risk of early adverse reactions, driving or
operating machines is not advisable for 1 hour post injection.


Undesirable effects
Adverse effects, which may occur in relation with the use of
Conray, are generally independent of the dose administered. They
are mild or moderate in the majority of cases, rarely severe or
life-threatening. However, even mild adverse events may be the
first indications of a serious, general reaction, which may occur in
rare cases after the use of any iodinated X-ray contrast medium.
The majority of reactions will occur within the first minutes post
injection. However, contrast medium-related hypersensitivity
reactions may also occur with a delay of some hours up to several
days. Common symptoms of delayed reactions are pruritus and
In the subsequent compilation, all symptoms are listed which have
been reported up to now in relation with the use of Conray, and
which are probably or possibly related to Conray.
Metabolic and nutritional disorders:
Very rare (< 0.01%):
Psychiatric disorders:
Very rare (< 0.01%):
Nervous system disorders:
Occasional (0.1% - 1%):
Rare (0.01% - 0.1%):



Pregnancy and lactation
There is inadequate evidence as to the safety of Conray in human
pregnancy. The pregnant female should not be submitted to X-rays
unless the radiologist considers it essential. Intravascular contrast
agents may cross the placenta and can potentially produce transient
fetal hypothyroidism. Lasting adverse effects on the fetus or
neonates have not been identified for Conray.

Over 10 years of age: Lower range of
adult dosage.
Femoral and other
peripheral arteriography

Interactions with other medicinal products and other forms of

Conray injections must never be injected into the
subarachnoid space.
Use in proven or suspected hypersensitivity to iodine
containing media.
Use in patients with uncontrolled hyperthyroidism.

Very rare (< 0.01%):

Special warnings and precautions for use
Conray 280 is not indicated for myelography. Intrathecal use may
lead to convulsions and further life-threatening neurotoxic effects.
Following the use of any contrast medium of this type, there is the
possibility of severe sensitivity reactions occurring. When they do,
they tend to occur in the first few minutes following the injection.
Therefore the patient should be kept under close observation
for 15 minutes following the last injection. It is essential to have
immediately available emergency resuscitation equipment,
including appropriate drugs, oxygen and means of administration.
The patient should remain in the hospital environment (but not
necessarily in the radiology department) for one hour after time of
injection. The patient should return to the radiology
department if any symptoms develop.
Particular caution should be exercised in patients with a history
of allergy, atopy, asthma, cardiac disease or a previous adverse
reaction with any contrast medium as they may be at higher
risk from developing anaphylaxis or cardiovascular collapse.
Consideration should be given to the use of low-osmolar radiocontrast media in such patients.

Caution must be exercised in patients with severely impaired renal
function, combined renal and hepatic disease, anuria, diabetes
mellitus, homozygotic sickle cell disease, or monoclonal gammopathy
(multiple myeloma, Waldenström’s macro-globulinaemia),
particularly when large doses are administered. Serious renal effects,
including acute renal failure, may occur in these patients. An effective
hydration prior to the administration of Conray is essential and may
decrease the risk of renal injury. Preparatory dehydration is dangerous
and may contribute to acute renal failure.
