Omnipaque injection 140 mg I/ml solution for injection – patient leaflet, side effects, dosage

1. WHAT OMNIPAQUE IS AND WHAT IT IS USED FOR

This medicine is for diagnostic use only. It is used only to help identify an illness. Omnipaque is a ‘contrast medium’. It is given before an X-ray to make the picture that your doctor takes clearer.

• Once injected, it can help your doctor tell apart normal or abnormal appearance and shape of some organs in your body.
• It can be used for X-rays of your urinary system, spine or blood vessels, including blood vessels of your heart.
• Some other people are given this medicine before or during a scan of their head or body using ‘computed tomography’ (also called a CAT scan). This type of scan uses X-rays.
• It can also be used to look at your salivary glands, stomach and intestine, or for looking in body cavities, such as in your joints or womb and ovarian tubes.
• It can also be used in cases of mammography examinations.

Your doctor will explain which part of your body will be scanned.

2. WHAT YOU NEED TO KNOW BEFORE YOU USE OMNIPAQUE

Do not use Omnipaque

• If you suffer from severe thyroid problems
• If you are allergic (hypersensitive) to iohexol or any of the other ingredients of Omnipaque (listed in Section 6).

Warnings and precautions

Check with your doctor before having Omnipaque:

• If you have ever had an allergic reaction after a medicine similar to Omnipaque, called a ‘contrast medium’.
• If you have any thyroid problems.
• If you have ever had any allergies.
• If you have asthma or if you are using beta adrenergic blocking agents.
• If you have diabetes.
• If you have any brain disease or tumours.
• If you have or have had severe heart disease (involving heart or blood vessels) including high blood pressure, blood clots, stroke and irregular heartbeats (arrhythmia).
• If you have kidney problems or both liver and kidney problems.
• If you have an illness called ‘myasthenia gravis’ (a condition causing severe muscle weakness).
• If you have a ‘phaeochromocytoma’ (constant or attacks of high blood pressure due to a rare tumour of your adrenal gland).
• If you have “homocystinuria” (a condition with increased excretion of the amino acid cysteine in urine)
• If you have any problems with your blood or bone marrow.

• If you have ever been dependent on alcohol or drugs.

• If you have epilepsy.
• If you are having a thyroid function test in the next weeks.

During or shortly after the imaging procedure you may experience a short-term brain disorder called contrast encephalopathy. Tell your doctor straight away if you notice any of the signs and symptoms related to this condition described in Section 4. Contrast-enhanced mammography exposes you to higher levels of ionizing radiation than traditional mammography, however, it is still within the range defined by the international guidelines for mammography. Radiation dose depends on the thickness of the breast and the type of mammography machine used.

If you are not sure if any of the above apply to you, talk to your doctor before having Omnipaque. Make sure to drink plenty of fluid before and after receiving Omnipaque. This applies especially to patients with multiple myeloma (white blood cells disease), diabetes, kidney problems, patients in bad general condition, children and elderly patients. Omnipaque contains sodium. This medicinal product contains less than 1 mmol sodium (23 mg) per ml, i.e. essentially “sodium free”.

Children and adolescents

Make sure to drink plenty of fluid before and after receiving Omnipaque. This applies especially to infants and small children. Drugs that can damage the kidneys should not be taken at the same time as Omnipaque. If Omnipaque has been given to the mother during pregnancy, the thyroid function of the newborn should be tested during the first week after birth. It is recommended that the testing is repeated again between 2 and 6 weeks of age in premature and low birth weight newborns.

Omnipaque may be removed from an infant’s body more slowly than an adult. Young infants (less than 1 year of age) and especially newly born are susceptible to changes in certain laboratory tests (in balance in salts and minerals) and circulatory changes in blood circulation (blood flow to the heart).

Taking other medicines and Omnipaque

Please tell your doctor if you are diabetic and are taking any medicine containing metformin, or have recently taken any other medicines, including medicines obtained without a prescription or if you are using beta-blockers, vasoactive substances, ACE- enzyme inhibitors or angiotensin antagonists (medicines used to treat high blood pressure)

or have recently been treated with interleukin-2 or interferons (medicines used to treat immune system diseases), neuroleptics or tricyclic antidepressants (medicines used to treat mental disorders like i.e. depression). This is because some medicines can affect the way Omnipaque works.

Beta-blockers may increase your risk of experiencing breathing difficulties and may interfere with the treatment of severe allergic reactions, which is a risk of Omnipaque. Fertility, Pregnancy and breast-feeding

You must tell your doctor if you are pregnant or think you may be pregnant. Your doctor will only use this product if it is considered that the benefit outweighs the risk for both the mother and the baby. If Omnipaque has been given to the mother during pregnancy, the thyroid function of the newborn should be tested during the first week after birth. It is recommended that the testing is repeated again between 2 and 6 weeks of age in premature and low birth weight newborns.

Breast-feeding may be continued normally after an examination with Omnipaque. Driving and using machines

Do not drive or use tools or machines after your last injection of

Omnipaque for:

• 24 hours, if it has been given into your spine, or
• one hour in all other cases.

This is because you may feel dizzy or have other signs of a reaction afterwards.

3. HOW TO USE OMNIPAQUE

Omnipaque will always be given to you by a specially trained and qualified person.

• Omnipaque will always be used in a hospital or clinic.
• They will tell you anything you need to know for its safe use.

Your doctor will decide the dose that is best for you.

The usual dose is:

• One single injection or you may be asked to swallow it.

After you have been given Omnipaque

You will be asked:

• to drink plenty of fluids afterwards (to help flush the medicine from your body), and
• to stay in or around the area where you had your scan or X-ray for around 30 minutes, and
• to stay in the clinic or hospital for one hour.

If you have any side effects during this time, tell your doctor straight away (see Section 4 ‘Possible Side Effects’).

The advice above applies to all patients who have had Omnipaque. If you are not sure about any of the above ask your doctor.

Omnipaque may be given in lots of different ways, a description of the ways it is usually given can be found below:

Injection into an artery or vein

Omnipaque will most commonly be injected into an arm vein or leg vein. Sometimes it will be given through a thin plastic tube (catheter), inserted into an artery usually in your arm or groin.

Injection into your spine

Omnipaque will be injected into the space around the spinal cord to see your spinal canal. If you have been given Omnipaque into your spine afterwards you will be asked to follow the advice below:

• to rest with your head and body upright for one hour, or six hours if you stay in bed, and
• to walk carefully and try not to bend down for six hours, and
• not to be completely alone for the first 24 hours after having Omnipaque, if you are an outpatient and have ever had fits.

The advice above applies only if you have had Omnipaque injected in to your spine. If you are not sure about any of the above ask your doctor.

Use in your body cavities or joints

Body cavities may be the joints, uterus and ovarian tubes. How and where Omnipaque is given will vary.

Use by mouth

For examination of the gullet, stomach or small bowel, Omnipaque is normally given by mouth. Omnipaque may be diluted with water for these examinations.

4. POSSIBLE SIDE EFFECTS

Like all medicines, Omnipaque can cause side effects, although not everybody gets them. Allergic reactions

If you have an allergic reaction when you are in hospital or a clinic having Omnipaque, tell the doctor straight away. The signs may include:

• wheeziness, difficulty in breathing or tightness or pain in your chest
• skin rash, lumps, itchy spots, blisters on skin and in mouth, red/itchy eyes, cough, running nose, sneezing or other allergic symptoms
• swelling of your face
• dizziness or feeling faint (caused by low blood pressure)
• severe skin reactions including potentially life-threatening skin rashes (Stevens- Johnson syndrome, toxic epidermal necrolysis), appearing initially as reddish target- like spots or circular patches often with central blisters on the trunk. Additional signs to look for include ulcers in the mouth, throat, nose, genitals and conjunctivitis (red and swollen eyes). These potentially life-threatening skin rashes are often accompanied by flu-like symptoms. The rash may progress to widespread blistering or peeling of the skin. If you have developed Stevens-Johnson syndrome or toxic epidermal necrolysis with the use of Omnipaque, you must not be re-started on Omnipaque at any time.

The above side effects may happen several hours or days after Omnipaque is given. If any of these side effects happen after you leave the hospital or clinic, go straight to the casualty department of your nearest hospital.

A short term decrease in formation of urine due to decreased kidney function is common after Omnipaque is given. This may lead to damage to the kidney.

Other side effects that you may have are listed below; these depend on how or why Omnipaque was given to you. Ask your doctor if you are not sure how you were given Omnipaque.

General

(Applies to all uses of Omnipaque)

Common: affects 1 to 10 users in 100

• feeling hot

Uncommon: affects 1 to 10 users in 1,000

• feeling sick (nausea)
• increased/abnormal sweating, cold feeling, dizziness/fainting
• headache

Rare: affects 1 to 10 users in 10,000

• allergic (hypersensitivity) reactions (may be fatal)
• slow heart rate
• pain around your stomach area, vomiting, fever

Very rare: affects less than 1 user in 10,000

• momentary change in sense of taste
• high or low blood pressure, shivering (chills)
• diarrhoea

• allergic reaction (may be life-threatening or fatal), including severe allergic reaction leading to shock and collapse, see ‘Allergic reactions’ above for other signs

  1209727 GBR Contrast-enhanced mammography (CEM)

Contrast-enhanced mammography results in higher patient exposure to ionizing radiation than standard mammography. Radiation dose depends on breast thickness, the type of mammographic device and the device's system settings. The overall CEM radiation dose remains under the threshold defined by international guidelines for mammography (below 3 mGy).

4.5 Interaction with other medicinal products and other forms of interaction

Use of iodinated contrast media may result in a transient impairment of renal function and this may precipitate lactic acidosis in diabetics who are taking metformin (see section 4.4).

Patients treated with interleukin-2 and interferons less than two weeks previously have been associated with an increased risk for delayed reactions (erythema, flu-like symptoms or skin reactions).

The concomitant use of certain neuroleptics or tricyclic antidepressants can reduce the seizure threshold and thus increase the risk of contrast medium-induced seizures.

Treatment with ß-blockers may lower the threshold for hypersensitivity reactions, as well as necessitating higher doses of ß-agonists when treating hypersensitivity reactions.

Beta-blockers, vasoactive substances, angiotensin-converting enzyme inhibitors, angiotensin receptor antagonists may reduce efficacy of cardiovascular compensation mechanisms of blood pressure changes.

All iodinated contrast media may interfere with tests on thyroid function, thus the iodine binding capacity of the thyroid may be reduced for up to several weeks. High concentrations of contrast media in serum and urine can interfere with laboratory tests for bilirubin, proteins or inorganic substances (e.g. iron, copper, calcium and phosphate). These substances should therefore not be assayed on the day of examination.

4.6 Fertility, pregnancy and lactation

Pregnancy

The safety of Omnipaque for use in human pregnancy has not been established. An evaluation of experimental animal studies does not indicate direct or indirect harmful effects with respect to reproduction, development of the embryo or foetus, the course of gestation and peri- and postnatal development. Since whenever possible, radiation exposure should be avoided during pregnancy, the benefits of an X-ray examination, with or without contrast media, should be carefully weighed against the possible risk. Omnipaque should not be used in pregnancy unless the benefit outweighs the risk and it is considered essential by the physician.

Apart from avoidance of exposition to radiation, the sensitivity of the foetal thyroid gland to iodine should be taken into account when risk and benefit are evaluated. Thyroid function should be checked in all neonates during the first week of life following administration of iodinated contrast agents to the mother during pregnancy. Repeat testing of thyroid function is recommended at 2 to 6 weeks of age, particularly in low birth weight newborn or premature newborn. Breast-feeding

Contrast media are poorly excreted in human breast milk and minimal amounts are absorbed by the intestine. Breast feeding may be continued normally when iodinated contrast media are given to the mother. The amount of iohexol in breast milk excreted in 24 hours after injection was 0.5% of the weight adjusted dose in a trial. The amount of iohexol ingested by the baby in the first 24 hours after injection corresponds to only 0.2% of the paediatric dose.

4.7 Effects on ability to drive and use machines

It is not advisable to drive a car or use machines for one hour after the last injection or for 24 hours following intrathecal procedure (see section 4.4). However, individual judgement must be performed if persistent post myelography symptoms. 4.8 Undesirable effects

The listed frequencies are based on internal clinical documentation and published large scale studies, comprising more than 200,000 patients.

The frequencies of undesirable effects are defined as follows:

Very common (≥1/10), common (≥1/100 to <1/10), uncommon (≥1/1,000 to <1/100), rare (≥1/10,000 to <1/1,000), very rare (<1/10,000) and not known (cannot be estimated from the available data)

General (applies to all uses of iodinated contrast media)

Below are listed possible general side effects in relation with radiographic procedures, which include the use of non-ionic monomeric contrast media. For side effects specific to mode of administration, please refer to these specific sections. Hypersensitivity reactions may occur irrespective of the dose and mode of administration and mild symptoms may represent the first signs of a serious anaphylactoid reaction/shock. Administration of the contrast medium must be discontinued immediately and, if necessary, specific therapy instituted via the vascular access.

A transient increase in S-creatinine is common after iodinated contrast media, contrast induced nephropathy may occur.

Iodism or “iodide mumps” is a very rare complication of iodinated contrast media resulting in swelling and tenderness of the salivary glands for up to approximately 10 days after the examination.

Immune system disorders:

Rare: Hypersensitivity (may be life-threatening or fatal) (including dyspnoea, rash, erythema, urticaria, pruritus, skin reaction, conjunctivitis, coughing, rhinitis, sneezing, vasculitis, angioneurotic oedema, laryngeal oedema, laryngospasm, bronchospasm or non-cardiogenic pulmonary oedema). They may appear either immediately after the injection or up to a few days later and may be indicative of the beginning of a state of shock. Hypersensitivity related skin reactions may appear up to a few days after the injection.

Very rare: Anaphylactic/anaphylactoid reaction (may be life-threatening or fatal) Not known: Anaphylactic/anaphylactoid shock (may be life-threatening or fatal) Nervous system disorders:

Intravascular use (Intraarterial and Intravenous use)

Please first read the section labelled "General". Below, only undesirable events with frequency during intravascular use of nonionic monomeric contrast media are described.

The nature of the undesirable effects specifically seen during intraarterial use depends on the site of injection and dose given. Selective arteriographies and other procedures in which the contrast medium reaches a particular organ in high concentrations may be accompanied by complications in that particular organ. Blood and lymphatic system disorders:

Not known: Thrombocytopenia

Description of selected adverse reactions

Thrombo-embolic complications have been reported in connection with contrast-enhanced angiography of coronary, cerebral, renal and peripheral arteries. The contrast agent may have contributed to the complications (see section 4.4). Cardiac complications including acute myocardial infarction have been reported during or after contrast-enhanced coronary angiography. Elderly patients or patients with severe coronary artery disease, unstable angina pectoris and left ventricular dysfunction had a higher risk (see section 4.4).

In very rare occasions the contrast medium may cross the blood-brain barrier resulting in uptake of contrast medium in the cerebral cortex and cause contrast encephalopathy after intravascular or intrathecal administration (see section 4.4). The symptoms may include headache, visual disturbance, cortical blindness, seizures, confusion, disorientation, somnolence, loss of consciousness, coma, loss of coordination, hemiparesis, speech disorder, aphasia, amnesia, and brain oedema. Symptoms usually occur within few minutes to 24 hours after the administration. In majority of the case reports the reaction lasted few hours to up to 72 hours.

Anaphylactoid reaction and anaphylactoid shock may lead to profound hypotension and related symptoms and signs like hypoxic encephalopathy, renal and hepatic failure (see section 4.4).

In several cases, extravasation of contrast media has caused local pain and oedema, which usually receded without sequelae. Inflammation, tissue necrosis and compartment syndrome have occurred (see section 4.4).

Paediatric patients:

Transient hypothyroidism has been reported in premature infants, neonates and in other children after administration of iodinated contrast media. Premature infants are particularly sensitive to the effect of iodine. Transient hypothyroidism in a premature breast fed infant has been reported. The nursing mother was repeatedly exposed to Omnipaque (see section 4.4).

Especially in infants and small children, adequate hydration should be assured before and after contrast media administration. Nephrotoxic medication should be suspended. The age dependent reduced glomerular filtration rate in infants can also result in delayed excretion of contrast agents.

Reporting of suspected adverse reactions:

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via Yellow Card Scheme

Website: https://yellowcard.mhra.gov.uk or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9 Overdose

Preclinical data indicate a high safety margin for Omnipaque and no fixed upper dose level has been established for routine intravascular use. Symptomatic overdosing is unlikely in patients with normal renal function unless the patient has received an excess of 2000 mg I/kg body-weight over a limited period of time. The duration of the procedure is important for the renal tolerability of high doses of contrast media (t_½ ~ 2 hours). Accidental overdosing is most likely following complex angiographic procedures in children, particularly when multiple injections of contrast medium with high- concentration are given.

In cases of overdose, any resulting water- or electrolyte imbalance must be corrected. Renal function should be monitored for the next 3 days. If needed, haemodialysis may be used for clearance of excessive contrast medium. There is no specific antidote.

1. 5. PHARMACOLOGICAL PROPERTIES

5.1 Pharmacodynamic properties

Pharmacotherapeutic group: X-ray contrast media, iodinated, ATC code: V08AB02 For most of the haemodynamic, clinical-chemical and coagulation parameters examined following intravenous injection of iohexol in healthy volunteers, no significant deviation from preinjection values has been found. The few changes observed in the laboratory parameters were minor and considered to be of no clinical importance.

5.2 Pharmacokinetic properties

Close to 100 per cent of the intravenously injected iohexol is excreted unchanged through the kidneys within 24 hours in patients with normal renal function. The maximum urinary concentration of iohexol appears within approximately 1 hour after injection. No metabolites have been detected. The protein binding of Omnipaque is very low (less than 2 %).

5.3. Pre-clinical Safety Data

Iohexol has a very low acute intravenous toxicity in mice and rats. Animal studies have shown that iohexol has a very low protein binding, and is well tolerated by the kidneys.
