How to use

Adult Dose: The normal adult dose of FLUORESCITE® Injection 10% (100 mg/mL) is 500 mg via intravenous administration. (2.1) Pediatric Dose: For children, the dose should be calculated on the basis of 7.7 mg for each kg of actual body weight (or 35 mg for each 10 pounds of body weight) up to a maximum of 500 mg via intravenous administration. (2.1) Do not mix or dilute with other solutions or drugs (2.2) 2.1 Dosing Adult Dose The normal adult dose of FLUORESCITE ® Injection 10% (100 mg/mL) is 500 mg via intravenous administration. Pediatric Dose For children, the dose should be calculated on the basis of 7.7 mg for each kg of actual body weight (or 35 mg for each 10 pounds of body weight) up to a maximum of 500 mg via intravenous administration. 2.2 Preparation for Administration Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration. Do not mix or dilute with other solutions or drugs. Flush IV before and after drugs are injected to avoid physical incompatibility reactions. 2.3 Administration Inject the dose rapidly (1 mL per second is normally recommended) intravenously into the antecubital vein, after taking precautions to avoid extravasation. A syringe, filled with FLUORESCITE, may be attached to transparent tubing and a 23 gauge butterfly needle for injection. Insert the needle and draw the patient’s blood to…

Side effects

The following adverse reactions associated with the use of FLUORESCITE were identified in clinical studies or postmarketing reports. Because some of these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The most common adverse reactions include skin discoloration, urine discoloration, nausea, vomiting, and gastrointestinal distress. (6) To report SUSPECTED ADVERSE REACTIONS, contact Alcon Laboratories,Inc. at 1-800-757-9195 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Skin and Urine Discoloration The most common reaction is temporary yellowish discoloration of the skin and urine. Urine may attain a bright yellow color. Discoloration of the skin usually fades in 6 to 12 hours and usually fades in urine in 24 to 36 hours. 6.2 Gastrointestinal Reactions Nausea, vomiting, and gastrointestinal distress are common adverse events. A strong taste may develop after injection. Diarrhea has also been reported. 6.3 Hypersensitivity Reactions Symptoms and signs of hypersensitivity have occurred. Generalized hives and itching, bronchospasm and anaphylaxis have been reported. Rare cases of death have been reported. [see Contraindications (4.1) and Warnings and Precautions (5.1) ]. 6.4 Cardiopulmonary Reactions Cardiac arrest, basilar artery…

Warnings

Important safety information

Respiratory reactions may require intervention. (5.1) Severe local tissue damage can occur with extravasation during injection. (5.2) Nausea and/or vomiting may occur within minutes following injection. (5.3) 5.1 Respiratory Reactions Monitor closely when used in patients with a history of allergy or bronchial asthma. An emergency tray should be available in the event of possible reaction to FLUORESCITE ® Injection 10%. If a potential allergy is suspected, an intradermal skin test may be performed prior to IV administration, (i.e., 0.05 mL injected intradermally to be evaluated 30 to 60 minutes following injection). Given the sensitivity and specificity of skin testing, a negative skin test is not proof that a patient is not allergic to fluorescein. 5.2 Severe Local Tissue Damage Avoid extravasation 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 reported: severe pain in the arm for several hours, sloughing of the skin, superficial phlebitis, subcutaneous granuloma, and toxic neuritis along the median curve in the antecubital area. When significant extravasation occurs, the injection should be discontinued and conservative measures to treat damaged tissue and to relieve pain should be implemented. [ see Administration (2.3) and Adverse Reactions (6.6) ] . 5.3 Gastrointestinal Distress Nausea and/or vomiting and gastrointestinal distress occur commonly within the first few minutes following injection. These reactions usually subside within 10 minutes. Diarrhea has also been reported.

Who should not take Fluorescite

FLUORESCITE ® Injection 10% is contraindicated in patients with known hypersensitivity to fluorescein or any other ingredients in this product (4.1) 4.1 Hypersensitivity FLUORESCITE ® Injection 10% is contraindicated in patients with known hypersensitivity to fluorescein sodium or any other ingredients in this product. Rare cases of death due to anaphylaxis have been reported. [see Warnings and Precautions (5.1) and Adverse Reactions ( 6.3 , 6.4 )]. Fluorescein sodium can induce serious 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. Detailed questioning of each patient is recommended before the angiography to evaluate any prior history of allergy.
