What OMNIPAQUE is used for

OMNIPAQUE is one of a group of medicines known as “contrast media” for diagnostic use. OMNIPAQUE is used in X-ray examinations in many different parts of the body for adults and children. It can make it easier to find and see abnormalities, and improves the diagnostic information needed by the doctor.

Taking other medicines

Tell the doctor if you are taking any other medicines, including medicines you buy without a prescription from a pharmacy, supermarket or health food shop. Some medicines may interfere with OMNIPAQUE. These include:

  • Biguanides (eg metformin) a medicine for diabetes. Your doctor may ask you not to take biguanides for 48 hours before receiving an injection of OMNIPAQUE.

These medicines may interact or affect the way OMNIPAQUE works. Check with your doctor or pharmacist if you are not sure whether you are taking biguanides or interleukin-2.

You should not eat or drink anything in the two hours before your examination with OMNIPAQUE. It is, however, important to drink plenty of water before the examination and after the examination.

How OMNIPAQUE is used

You will be given OMNIPAQUE before or during your X-ray examination. OMNIPAQUE will be injected by a qualified person. The amount injected can vary depending on the type of examination used, your age and your weight.

If you receive an overdose

An overdose may lead to serious effects on the kidneys. If you are given an overdose, your doctor will decide how to treat you.

While you are using OMNIPAQUE

After examination of the spinal canal (myelography), you will be asked to rest in bed in a sitting or semi-sitting position and to avoid bending down for the first few hours. It is not advisable to drive a vehicle or operate machinery for at least 24 hours following an intrathecal examination (myelography).

If you need to have a thyroid function test within the next 14 days after examination with OMNIPAQUE, please tell your doctor before the test is done.

If you have any blood or urine tests on the day of your examination with OMNIPAQUE, tell your doctor you are using OMNIPAQUE. OMNIPAQUE may affect the results of some laboratory tests.

Things to be careful of

Delayed reactions of iodine-containing dyes may occur.

Side effects

Usually, OMNIPAQUE does not cause any problems. It can, however, sometimes cause unwanted effects in some people. The most frequent effect is a mild sensation of warmth or pain during the injection. Although there is a risk that you might get an unwanted effect, your doctor will have chosen this treatment by considering these risks and the benefits for the examination.

If you get any of the following during or after the examination:

  • Wheeziness, difficulty in breathing or tightness or pain in the chest;
  • Skin rash, itching, swelling or other allergic symptoms;
  • Dizziness or feeling faint;

you should tell your doctor straight away.

  • Altered taste sensation in the mouth;
  • Abdominal discomfort;
  • Nausea, vomiting or diarrhoea;
  • Headache, dizziness, restlessness;
  • Chest pain, change in blood pressure or heart rate;
  • Blurred vision, auditory disturbance, confusion or a change in your sensation of touch;

  • Difficulty in voiding;
  • Backache, pain in the arms and legs;
  • Swelling and tenderness of the salivary glands for up to approximately 10 days after the examination.
  • Flushing or feeling hot
  • Shortness of breath or coughing

These effects are often mild and of short duration. If they become severe or last for more than a few days, tell your doctor. Sometimes, medical treatment is necessary.

If you get any of the following during or after myelography:

  • Sensitivity to light
  • Neck stiffness
  • Muscle weakness or spasm

you should inform your doctor immediately.
