- if you have an overactive thyroid gland (hyperthyroidism).
Warnings and precautions
Tell your doctor or healthcare professional before being given Optiray if you have:
- asthma or previously had allergic reactions such as nausea, vomiting, low blood pressure, skin symptoms
- heart failure, high blood pressure (hypertension), circulation disorders or had a stroke, and if you are very elderly
- diabetes
- kidney or liver disease
- brain disorders
- problems with bone marrow, such as certain blood cancers known as paraproteinaemia, multiple myeloma
- certain red blood cell abnormalities, known as sickle cell anaemia.
- a tumour of the adrenal gland, which affects your blood pressure known as phaeochromocytoma
- increased homocysteine amino acid level, due to abnormal metabolism
- recent gall bladder investigation with contrast media
This should be postponed as Optiray may influence results for up to 16 days.
Serious skin reactions including drug reaction with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (Lyell’s syndrome or TEN) and acute exanthematous pustulosis (AGEP), which can be life-threatening, have been reported with the use of Optiray.
During or shortly after the imaging procedure you may experience a short-term brain disorder called encephalopathy. Tell your doctor straight away if you notice any of the symptoms related to this condition described in section 4.
Children younger than 18 years
Optiray 300 is used for imaging of vessels or kidneys in this age group. With paediatric patients younger than 3 years, including newborns whose mothers have received an iodinated contrast medium during pregnancy, controls of thyroid hormones known as TSH and T4 are recommended. These checks take place 7 - 10 days and 1 month after administration of Optiray.
Other medicines and Optiray
Always tell your doctor, X-ray specialist or health care provider, if you are taking or have recently taken any other medicines (this includes complementary or traditional medicines).
The following medicines can influence or be influenced by Optiray:
- metformin: used for treatment of diabetes. Your doctor will measure your kidney function before and after having X-ray contrast media. As metformin may accumulate in the body and lead to a serious metabolic disorder, it should be stopped at the time of the investigation. It should not be restarted for at least 48 hours after the investigation, and only when your kidney function has returned to its previous level.
- interleukin: medicines used in certain types of tumours - the rate of side effects to Optiray may be increased;
- certain medicines to increase blood pressure (vasopressors) due to narrowing of blood vessels. To prevent any risk of nervous disorders, Optiray should never be used while using these medicines.
- general anaesthetics. A higher frequency of side effects has been reported.
- diuretics: medicines that increase urine production and lower blood pressure. In case of dehydration caused by the use of diuretics, the use of iodinated contrast media may increase the risk of acute kidney failure.
Optiray with food and drink
It may be necessary to restrict your food and drink prior to the examination, so please ask for advice. However, if you have kidney disease, water should not be restricted because dehydration (lack of water in the body tissue) may further decrease the kidney function.
Pregnancy and Breastfeeding
Optiray should not be used during pregnancy or lactation.
Pregnancy: If you are pregnant or there is any possibility that you may be pregnant or if you are breastfeeding your baby, please consult your doctor or X-ray specialist or other health care provider for advice before being given Optiray. The risk to the unborn baby with use of Optiray in pregnancy cannot be excluded. However, any X-ray investigations during pregnancy may have a risk for the unborn baby.
Breastfeeding: It is not known whether Optiray is excreted in human breast milk. However, approximately 1% of iodine-containing X-ray contrast media similar to Optiray is excreted into breast milk. Although it has not been established that this would affect your baby, you should rather discontinue breastfeeding your baby for one day after the injection. Discuss this with your doctor or X-ray specialist.
Driving and using machines
Driving or operating machines is not advisable for up to 1 hour after injection. In addition, symptoms such as dizziness, drowsiness, fatigue and visual disturbances have been reported. If this affects you, do not attempt any activities which require concentration and the ability to react appropriately.
Optiray contains sodium. This medicine contains less than 1 mmol sodium (23 mg) per 100 ml, that is to say essentially “sodium-free”.
