US labeling:
IV:
Blood flow, tissue perfusion, and vessel visualization: Administer as a bolus injection via a central or peripheral IV line using a 3-way stopcock; immediately follow with a 10 mL bolus of NS. Use with the SPY Elite or PINPOINT Fluorescence imaging systems or an FDA-approved imaging device that is specifically indicated for use with indocyanine green for fluorescence imaging of blood flow, tissue perfusion, and vessels. A visible fluorescence response in blood vessels may be seen within 5 to 15 seconds after administration.
Cardiac output determination: In the performance of dye dilution curves, administer as a single bolus as rapidly as possible via a cardiac catheter into selected sites in the vascular system. Inject the dose of dye in 1 mL volume; an average of 5 dilution curves are recommended in the procedure. Attach a recording instrument (oximeter or densitometer) to a needle or catheter for sampling of the dye-blood mixture from a systemic arterial sampling site. Use sterile water for injection to rinse the syringe; use isotonic saline to flush the residual dye from the cardiac catheter into circulation to avoid hemolysis; saline should be used in all other parts of the catheterization procedure. See manufacturer's labeling for specific information regarding calibration of dye curves.
Extrahepatic biliary ducts: Administer at least 45 minutes prior to surgery. Use with the PINPOINT Fluorescence imaging system or an FDA-approved imaging device that is specifically indicated for use with indocyanine green for fluorescence imaging of extrahepatic biliary ducts. A visible fluorescence response in blood vessels may be seen within 45 minutes after administration.
Hepatic function studies: Inject into the lumen of an arm vein as rapidly as possible, without allowing the dye to escape outside the vein. If the photometric method is used, prior to injecting indocyanine green, withdraw 6 mL venous blood from the patients arm for serum blank and standard curve construction, and through the same needle, inject the correct amount of dye. Ear oximetry has also been used; see manufacturer's labeling for additional information.
Ophthalmic angiography studies: Administer as a bolus injection into the antecubital vein; immediately follow with a 5 mL bolus of normal saline.
Intradermal: Lymphatic mapping of breast cancer: Administer into the peri-areolar area at the 12 and 9 o'clock positions for the right breast or at the 12 and 3 o'clock positions for the left breast; if an additional dose is necessary, administer at the 12, 3, and 9 o'clock positions. Use with the SPY Portable Handheld Imaging (SPY-PHI) system or an FDA-approved imaging device that is specifically indicated for use with indocyanine green for fluorescence imaging of lymph nodes and delineation of lymphatic vessels during lymphatic mapping of breast cancer. A visible fluorescence response in lymph nodes and lymphatic vessels may be seen within 1 minute after administration.
Interstitial: Lymphatic mapping of cervical and uterine cancer: Administer into the cervix at the 3 and 9 o'clock positions with a superficial (1 to 3 mm) and deep (1 to 3 cm) injection at each position for a total of 4 injections. Use with the PINPOINT Fluorescence imaging system or an FDA-approved imaging device that is specifically indicated for use with indocyanine green for fluorescence imaging of lymph nodes and delineation of lymphatic vessels during lymphatic mapping of cervical and uterine cancer. A visible fluorescence response in lymph nodes and lymphatic vessels may be seen within 1 minute after administration.
Canadian labeling:
IV:
Blood flow and tissue perfusion imaging: Administer as a bolus injection via a central or peripheral IV line using a three-way stopcock; immediately follow with a 10 mL bolus of NS. A visible fluorescence response in blood vessels may be seen within 5 to 15 seconds after administration.
Extrahepatic biliary anatomy imaging: Administer ~45 minutes prior to surgery; a visible fluorescence response in blood vessels may be seen ~45 minutes after administration.
Interstitial: Lymph node and lymphatic vessels imaging: Administer into the cervix at the 3 and 9 o'clock positions with a superficial (1 to 3 mm) and deep (1 to 3 cm) injection at each position for a total of 4 injections while patient is under anesthesia. A visible fluorescence response in lymph nodes and lymphatic vessels may be seen within 1 minute after administration.
Parenteral: IV:
Blood flow, tissue perfusion, and vessel visualization: IC-Green, Spy Agent Green: Infants, Children, and Adolescents: Administer via central or peripheral vein by rapid bolus; follow immediately with NS flush (eg, 10 mL in adults).
