Verdye, as it is known in most European territories, is a
sterile, lyophilized green powder containing the active ingredient Indocyanine
Green (ICG).

Following intravenous (I.V.) injection, ICG or Indocyanine
Green binds rapidly to plasma proteins and remains within the blood vessels. It
has a half-life of 3 to 4 minutes and is removed from circulation exclusively
by the liver and then eliminated through the bile. It does not undergo
metabolism.

Indocyanine Green (ICG) is dissolved using sterile water for
injection and is for single use only.

Verdye, Indocyanine Green (ICG), contains up to 5% sodium iodide. Allergic reactions have been reported in patients with and without a history of allergy to iodides. It is known that in very rare cases (<1/10,000), ICG can cause nausea and anaphylactic reactions.

With normal liver function, the plasma half-life of Indocyanine Green (ICG) is 3-4 minutes. Measurements can therefore be repeated after 15-20 minutes.

After I.V. injection, Indocyanine Green (ICG) fluorescence can be visualized in less than one minute.

Verdye, Indocyanine Green (ICG) should be dissolved with sterile water for injection to a final concentration of 5 mg per 1 ml.

The dosage depends on the intended application and the weight of the patient. 

For details, please see the instructions for use at Verdye Product Information.
