Consumer medicine information (CMI) leaflet

Please read this leaflet carefully before you start using Retinofluor Injection.

What is in this leaflet

This leaflet answers some common questions about Retinofluor. It does not contain all the available information. It does not take the place of talking to your doctor.

All medicines have risks and benefits. Your doctor has weighed the risks of you being given Retinofluor against the benefits they expect it will have for you.

If you have any concerns about being given this medicine, ask your doctor.

Keep this leaflet in a safe place. You may need to read it again.

What Retinofluor is used for

Retinofluor is used to highlight blood vessels in the back of the eye so that a special camera can be used to take pictures and analyze the blood circulation in the eye. This helps doctors diagnose any problems or diseases of the eye.

This medicine belongs to a group of medicines called synthetic dyes. Retinofluor is an orange to red coloured fluorescent dye.

This medicine works by making the blood vessels in the eye fluoresce for a short time so that these vessels can be more easily seen in a photograph.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

Before you are given Retinofluor

When you must not be given it

You should not be given Retinofluor if you have an allergy to:

  • any medicine containing fluorescein sodium
  • any of the ingredients listed at the end of this leaflet
  • any other similar medicines such as synthetic dyes.

Some of the symptoms of an allergic reaction may include:

  • shortness of breath
  • wheezing or difficulty breathing
  • swelling of the face, lips, tongue or other parts of the body
  • rash, itching or hives on the skin.

You should not be given this medicine if you are pregnant. It may affect your developing baby if you are given it during pregnancy.

Do not breast-feed if you are being given this medicine. The active ingredient in Retinofluor passes into breast milk and there is a possibility that your baby may be affected.

This medicine should not be given to children. Safety and effectiveness in children has not been established.

You should not be given this medicine if the solution is discoloured, cloudy, turbid, or a precipitate or particles are present. The solution is normally an orange to red liquid.

The doctor or nurse will check to ensure the medicine is not past its expiry date and has not been tampered with.

If you are not sure whether you should be given this medicine, talk to your doctor.

Before you are given it

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.

Tell your doctor if you have or have had any of the following medical conditions:

  • heart disease or heart problems
  • diabetes mellitus
  • asthma
  • suffer from any allergies.

If you have not told your doctor about any of the above, tell him/her before you are given Retinofluor.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including any that you get without a prescription from your pharmacy, supermarket, health food shop, naturopath or herbalist. Some medicines and Retinofluor may interfere with each other.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while being given this medicine.

How Retinofluor is given

Retinofluor must only be given by a doctor or nurse.

How it is given

Retinofluor is rapidly injected into a vein, usually at the bend of the elbow (the antecubital vein).

How much is given

Your doctor will decide what dose of Retinofluor you will receive. This depends on your medical condition and other factors, such as your weight.

Usually only a single dose of Retinofluor is required.

If you are given too much (overdose)

Retinofluor must only be given by a doctor or nurse so an overdose is not likely to occur.

If you experience any severe side effects tell your doctor or nurse immediately. The symptoms of a side effect are listed under Side effects below.

If you notice any symptoms of an overdose immediately contact your doctor or go to the Emergency Department at the nearest hospital.

Contact the Poisons Information Centre on 13 11 26 for further advice on overdose management.

While you are being given Retinofluor

Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you have been given Retinofluor.

Tell any other doctors, dentists, and pharmacists who treat you that you have been given this medicine.

If you are about to have any blood tests, tell your doctor that you have been given this medicine. It may interfere with the results of some tests.

Things you must not do

Do not drive or operate machinery after being treated with Retinofluor. This medicine causes a temporary decrease in vision in most people. Do not drive, operate machinery or do anything else that could be dangerous.

Things to be careful of

If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly. Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure. If this problem continues or gets worse, talk to your doctor.

Side effects

Tell your doctor or nurse as soon as possible if you do not feel well while you are being given Retinofluor. This medicine may have unwanted side effects in a few people. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.

Do not be alarmed by the following lists of side effects. You may not experience any of them.

Ask your doctor to answer any questions you may have.

Retinofluor will cause:

  • a temporary decrease in vision and images appear red as a result of the flash photography.
  • urine to turn orange in colour for a brief period.

Tell your doctor or nurse if you notice any of the following and they worry you:

  • nausea
  • headache
  • tingling or numbness in the hands or feet, tongue and lips
  • excessive sneezing
  • yellow discolouration of the skin and eyes.

The above list includes the more common side effects of your medicine.

Tell your doctor as soon as possible if you notice any of the following:

  • dizziness, light-headedness
  • skin rash, itching, hives
  • vomiting, stomach upset, pain or cramping
  • intense lower back pain.

The above list includes serious side effects that may require medical attention.

If any of the following happen, tell your doctor immediately or go to the Emergency Department at your nearest hospital:

  • chest pain
  • shortness of breath, difficulty breathing which may be very severe and usually worsens when lying down
  • swelling, redness and severe pain at the injection site
  • sudden severe signs of allergy including:
    - rash, itching or hives on the skin
    - swelling of face, lips or tongue
    - shortness of breath, wheezing or trouble breathing.

The above list includes very serious side effects. You may need urgent medical attention or hospitalisation. These side effects are very rare.

Tell your doctor or nurse if you notice anything that is making you feel unwell. Other side effects not listed above may also occur in some people.

After being given Retinofluor

BRAND INFORMATION

Brand name

Retinofluor

Active ingredient

Fluorescein sodium

Schedule

S4

 

1 Name of Medicine

Fluorescein sodium.

2 Qualitative and Quantitative Composition

Retinofluor injection 10% contains fluorescein sodium 500 mg in 5 mL or 1 g in 10 mL water for injections as a sterile solution in single dose vials.
Retinofluor injection 25% contains fluorescein sodium 1.25 g in 5 mL water for injections as a sterile solution in single dose vials.
For the full list of excipients, see Section 6.1 List of Excipients.

3 Pharmaceutical Form

Retinofluor is an orange/red sterile solution for intravenous administration.

4 Clinical Particulars

4.1 Therapeutic Indications

Diagnostic.

Intravenous injection of fluorescein sodium dye followed by multiframe photography (angiography) or ophthalmoscopic evaluation (angioscopy). It is used in evaluation of a wide range of retinal and choroidal diseases. It is less commonly used to evaluate abnormalities of the optic nerve and iris. It may be used in diagnosis and management of macular and vascular (including diabetic) diseases.

4.2 Dose and Method of Administration

Product is for single use in one patient only. Discard any residue.
After taking precautions to avoid extravasation (e.g. checking with the lights on) 10% or 25% fluorescein sodium injection is rapidly injected in the antecubital vein and then the room lights turned off.
A recommended dose is 500 mg but this dose may be varied depending on the patient and the camera used in the diagnostic procedure and the individual experience of the operator. It is recommended that the dose be kept as low as possible.
About ten minutes after the injection, very little of the fluorescein sodium dye remains in the eye. The retina and choroidal vessels are stained within 15 seconds and the optic disc will normally fluoresce for several hours after injection.

4.3 Contraindications

Sensitivity to fluorescein sodium or any components in the injection. Concomitant use of contact lenses.

4.4 Special Warnings and Precautions for Use

Not for intrathecal use - for ophthalmic diagnostic use only.

General.

Fluorescein sodium contains no iodine. A yellowish discolouration of the skin, urine and conjunctiva may occur. This usually subsides after several hours. Fluorescein sodium can stain skin, clothing, and soft contact lenses on contact. Intraocular fluorescein can produce transient blurring of vision.
This product is only to be used intravenously in ophthalmic diagnostic procedures. Do not mix or dilute with any other solutions or medicines. If a catheter is used, flush pre and post use to avoid any potential incompatibility reactions. Don't use if container or closure is damaged in any way.
The benefit to risk of the angiography procedure should be considered in patients with pre-existing conditions such as cardiovascular disease, diabetes mellitus, and multiple concomitant drug therapies (in particular, beta blockers).

Extravasation at the injection site.

Extravasation should be avoided during injection as the high pH of fluorescein solution can result in severe local tissue damage. The following complications resulting from extravasation of fluorescein have been noted to occur: sloughing of the skin, superficial phlebitis, subcutaneous granuloma, and toxic neuritis along the median curve in the antecubital area. Complications resulting from extravasation can cause severe pain in the arm for up to several hours. The correct intravenous position of the needle tip must be ascertained. When extravasation occurs, the injection should immediately be discontinued and conservative measures to treat damaged tissue and relieve pain should be implemented.

Cardiovascular disease.

Patients with a history of cardiovascular disease require careful evaluation before undergoing an elective procedure with fluorescein sodium. Rarely, severe cardiovascular complications such as chest pain, myocardial infarction and death have occurred following administration of fluorescein sodium.
Detailed questioning of each patient must be carried out before the angiography to evaluate any prior history of cardiopulmonary disease or allergy or concomitant medications.

Hypersensitivity reactions.

Fluorescein sodium can induce serious hypersensitivity and intolerance reactions. These reactions of intolerance are always unpredictable but they are more frequent in patients who have previously experienced an adverse reaction after fluorescein injection (symptoms other than nausea and vomiting) or in patients with history of allergy such as food or drug induced urticaria, asthma, eczema, allergic rhinitis, or in patients with history of bronchial asthma.
Intradermal skin tests have limited predictive value for serious intolerance reactions to fluorescein. Fluorescein intolerance reactions can occur following a negative intradermal skin test.
In the event of serious hypersensitivity and intolerance reactions during a first angiography, the benefit of an additional fluorescein angiography should be balanced with the risk of severe hypersensitivity reactions (with fatal outcome in some cases).
The risk of hypersensitivity reactions with fluorescein sodium requires:
Close monitoring of the patient by the ophthalmologist performing the examination, throughout the examination and for at least 30 minutes thereafter;
Maintaining the infusion line for at least 5 minutes, to treat a possible severe adverse reaction without delay;
To have at one's disposal appropriate material for emergency resuscitation which is based at first on the installation of a second intravenous line, allowing the restoration of the plasma volume (aqueous solution polyionic or colloidal substitute of plasma) and the intravenous injection of adrenaline at the recommended dosage;
In patients identified as being at risk of hypersensitivity reactions, but in whom a fluorescein angiography is considered to be essential, it is recommended to carry out the procedure with the equipment and personnel trained in emergency resuscitation in the treatment room.

Anaphylaxis.

Fluorescein sodium injection, may, rarely, cause life threatening or fatal anaphylaxis. A protocol for management of anaphylaxis and appropriate resuscitation equipment such as adrenaline for intravenous or intramuscular use, intravenous fluids and oxygen must always be available in case of such a reaction.

Bronchial asthmatic patients and patients with any history of allergy.

Bronchial asthmatic patients and patients with any history of allergy must be treated with special caution. This may involve treatment with antihistamines and steroids, respectively. Acute pulmonary oedema has been reported in 2 patients following administration of fluorescein sodium.

Diabetes mellitus.

In some patients with non-insulin dependent diabetes mellitus there has been an increase in whole blood viscosity, erythrocyte elongation index, blood pH, carboxyhaemoglobin and methaemoglobin levels and a sudden reduction of red cell acetylcholinesterase activity. These findings suggest that fluorescein interferes with the red cell membrane and with microcirculatory blood flow. The clinical relevance of these findings is uncertain.

Patient aftercare.

Patients should be escorted by a responsible adult from the testing site.

Special instructions.

Patients should expect temporary decrease in vision and red after image secondary to flash photography.
The skin and urine may be coloured yellow but this is transient. Fluorescein sodium can stain skin, clothing and soft contact lenses on contact. Intraocular fluorescein can produce transient blurring of vision.

Use in renal impairment.

Limited experience in renally impaired subjects suggests that no dose adjustment is necessary in renal impaired patients.
Fluorescein Angiography (FA) may cause Contrast-Induced Nephropathy (CIN) based on increased serum creatinine. CIN is a possible risk factor for end-stage renal disease progression.

Use in hepatic impairment.

Fluorescein undergoes hepatic metabolism to fluorescein glucuronide.

Use in the elderly.

No overall differences in safety or effectiveness have been observed between elderly and other adult patients.

Paediatric use.

Safety and effectiveness in children have not been established.

Effects on laboratory tests.

The fluorescence may interfere with the analysis of blood and urinary parameters for a period of 3 to 4 days.

4.5 Interactions with Other Medicines and Other Forms of Interactions

Fluorescein is a relatively inert dye and specific drug interaction studies are not reported. There are few case reports of potential interactions with organic anion transporters and interference with certain laboratory tests. Caution is advised when performing therapeutic drug monitoring for medicines with a narrow therapeutic window, e.g. digoxin, quinidine. Compounds that inhibit or compete with the active transport of organic anions (e.g. probenecid) may affect the systemic profile of fluorescein.
The concomitant use of Retinofluor injection with beta-blocking agents (including eye-drop solutions) may rarely provoke severe anaphylactic reactions. Beta-blocking agents could reduce the vascular compensation reactions to anaphylactic shock and also reduce the effectiveness of adrenaline in the presence of cardiovascular collapse.
Concomitant intravenous injection of other solutions or the mixing of Retinofluor injection with other solutions or medicines should be avoided as the possibility of interactions cannot be excluded.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

No studies investigating the effect of fluorescein on fertility have been conducted.
(Category B2)
Embryo-fetal toxicity studies in animals showed that doses of sodium fluorescein associated with exposure levels approximately 9-times higher (rats) or the same (rabbits) as the human dose (on relative mg/m2 body surface area basis) caused no fetal harm when administered IV during organogenesis.
Avoid angiography on patients who are pregnant, especially those in the first trimester. There have been no adequate and well-controlled human studies on the safety of Retinofluor injection during pregnancy. Retinofluor injection should be used in pregnancy only if clearly needed.
 Fluorescein has been demonstrated to be excreted in human milk for up to 7 days. Following fluorescein angiography, breastfeeding should therefore be discontinued for at least 7 days, and the milk should be pumped off and discarded during this period. Because of the potential for serious reactions in breastfed infants from fluorescein, a decision should be made whether to discontinue breastfeeding or to discontinue the medicine, taking into account the importance of the medicine to the mother.

4.7 Effects on Ability to Drive and Use Machines

The patient must be made aware that after application and until visual acuity returns to normal, driving a vehicle or operating dangerous machinery is not recommended.
