1. What Verdye is and what it is used for
Verdye is a dark green powder that is mixed with water to prepare injectable solutions. The active substance of the solution is called indocyanine green, a dye. This dye is injected into one of your veins, where it mixes with the blood. Your doctor will be able to see:
- how far the dye spreads from where it was injected
- how much of it is in different parts of your body.
When Verdye is injected into the skin or subcutaneous fat tissue of patients with breast cancer, it accumulates in the lymph nodes and the lymphatic pathways are visualized.
This medicine is for diagnostic use only, to determine what medical problems you may have, for example:
- how the blood circulation works in a part of your body, for example:
- the heart
- the brain
- the liver
- a layer of the inner part of the eye called the choroid.
- how much blood is in certain parts of your body.
- how your liver works.
Verdye is also used to make lymph nodes and lymphatic pathways visible or to identify them during surgery in adult patients with breast cancer. For this purpose, the medicine is injected into the skin, subcutaneous fat tissue, or the tumor area, rather than into the veins.
The lymph nodes closest to the tumor are called sentinel lymph nodes. It is most likely that these lymph nodes and the associated lymphatic vessels are the first place where cancer cells spread. When Verdye has reached the sentinel lymph nodes, it can be checked if cancer cells are present. Verdye accumulates in the sentinel lymph nodes and can be detected by a special camera.
2. What you need to know before you use Verdye
Do not use Verdye:
- if you are allergic to indocyanine green or any of the other ingredients of this medicine (listed in section 6).
- if you have hyperthyroidism or benign tumors of the thyroid gland.
- if you have ever experienced any side effects after receiving these injections.
Warnings and precautions
Talk to your doctor, pharmacist, or nurse before starting to use Verdye.
Be especially careful with Verdyeif:
- you have kidney failure.
Talk to your doctor to see if this medicine is suitable for you.
- if you are going to have a test called "radioactive iodine uptake", which evaluates thyroid function.
This test should be delayed for at least one week after receiving Verdye, because the injection could affect the result of the thyroid test.
The skin may become more sensitive to sunlight and UV radiation in patients who receive Verdye injected into the skin or subcutaneous fat tissue. Therefore, affected patients should avoid direct exposure to the sun or artificial UV radiation (e.g., tanning bed) for at least 1 week after the application of Verdye, until any green discoloration at the injection site has disappeared.
The identification of sentinel lymph nodes and the visualization of lymphatic pathways may be affected if they are located in deeper tissue layers or are covered by fatty tissue. Similarly, in patients with severe obesity (BMI > 40), the mapping of sentinel lymph nodes and the visualization of lymphatic pathways may be affected. Indocyanine green may be used in combination with radiopharmaceuticals when indicated for the detection of sentinel lymph nodes.
Patient preparation
It may be useful to administer medication to prevent nausea and vomiting to sensitive patients and to perform the injection slowly.
Patients with renal and hepatic impairment
Since adverse reactions have occurred in patients with advanced renal failure with the administration of indocyanine green, special attention should be paid to the indication for the use of Verdye in these patients.
Hepatic perfusion and/or reduced hepatic function will lead to a reduced plasma disappearance rate of indocyanine green.
Patients with cardiac insufficiency
Cardiac insufficiency may influence the extraction rate of indocyanine green due to reduced hepatic/splenic perfusion.
Children and adolescents
The use of Verdye is contraindicated in premature and newborn infants who are indicated for exchange transfusion due to hyperbilirubinemia.
Use of Verdyewith other medicines.
Tell your doctor or pharmacist if you are using or have recently used or might use any other medicines.
Tell your doctor if:
- you are taking any medicine that affects liver function, because the process of eliminating indocyanine green from the body after injection may be affected.
- you are taking, or think you may be taking, any of the medicines listed below, because some of these medicines may alter the absorption of indocyanine green, the active substance of Verdye, and may make the diagnosis inaccurate:
- anticonvulsants (medicine to treat epilepsy)
- cyclopropane (anesthetic)
- enalapril maleate (medicine to treat hypertension)
- haloperidol (medicine to treat mental illnesses and anxieties)
- meperidine (strong pain reliever)
- metamizole (pain reliever)
- methadone (medicine for opioid addiction substitution treatment)
- morphine and other opioids (strong pain relievers and/or antidiarrheal)
- nifedipine (medicine to treat hypertension)
- nitrofurantoin (antibiotic)
- phenobarbital (medicine to treat epilepsy and anesthetic)
- phenylbutazone (pain reliever)
- progestin (contraceptive)
- propranolol (medicine to treat hypertension and heart conditions)
- rifampicin (antibiotic)
- any injection containing sodium bisulfite (preservative).
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.
Driving and using machines
No studies have been conducted on the effects on the ability to drive and use machines.
Talk to your doctor before driving or using machines immediately after an injection.
3. How to use Verdye
Follow the instructions for administration of this medicine exactly as indicated by your doctor. If you are unsure, consult your doctor again.
The injection is administered only under the supervision of a doctor.
- To dissolve indocyanine green, only water for injectable preparations is used.
- The injection solution must be inspected before administration. If it is cloudy, it will not be used.
- The doctor or nurse injects the medicine directly into a vein using a needle, catheter, or cardiac catheter.
- The vein chosen for injection depends on the type of study being performed.
- If this medicine is injected into a vein in the arm, the doctor or nurse may apply a temporary tourniquet beforehand. This facilitates the insertion of the needle into the vein.
- The dose you receive will depend on the type of test being performed and your body weight.
- Your doctor may add a product called heparin to the blood samples obtained. (It serves to prevent the samples from clotting.)
- If this medicine is injected into the skin, subcutaneous fat tissue, or the tumor area, a specially designed needle will be used.
