Fluorescien Uses, Dosage, Side Effects, Mechanism of Action, How Long Does it Take to Work? Fluorescien is a brand name. Its generic name is Fluorescein.

Fluorescien Introduction

Fluorescien, or fluorescein diacetate, is a fluorescent dye used to detect and diagnose diseases and medical conditions. It is absorbed into the cells and then converted to fluorescein, which emits a bright blue-green fluorescence. Fluorescien is used for diagnosing conditions affecting the eyes, lungs, urinary tract, liver, and other organs.

Uses for Fluorescien

Fluorescien is used to diagnose conditions including corneal abrasions, dry eye syndrome, conjunctivitis, glaucoma, and dry macular degeneration. This dye is also used to diagnose and examine the small blood vessels in the brain, to detect fungal and bacterial infections, to evaluate blood vessels in the liver, and to identify blockages in the urinary tract.

Mechanism of Action

Fluorescien is an organic dye that absorbs and emits short-wave blue-green light when it comes into contact with cells. It is absorbed through the cornea or through the skin when it is applied as a solution. It then passes into cells and is converted to fluorescein, which emits a bright blue-green fluorescence.

How Long Does It Take To Work?

Fluorescien works quickly. It is typically visible almost immediately after it is applied, though the intensity of the fluorescence may vary depending on the concentration of the dye. The intensity of the fluorescence will usually increase over time, becoming most intense within a few minutes.

Absorption

Fluorescien is absorbed into the body through the skin or the cornea. When it enters the body, it is converted into fluorescein, which emits a bright blue-green fluorescence.

Route of Elimination

Fluorescien is mostly eliminated from the body within 24 hours, mostly from the urinary tract. However, it may remain in the body for up to two days.

Dosage

The dose of fluorescein depends on the patient's age and condition. The typical adult dose is 1-2 drops of a 5% fluorescein solution in the eye or injected underneath the skin. For children, the recommended dose is 0.1-1.0 drops. It is important to follow the instructions of the doctor or pharmacist to ensure optimal safety and efficacy.

Administration

Fluorescien can be administered as a drops in the eye, as an injection, or as a topical ointment or cream. When using fluorescein as an injectable, it should be injected slowly and carefully to avoid any adverse reactions.

Side Effects

The most common side effect of fluorescein is redness and irritation at the site of administration. Other side effects may include nausea, diarrhea, vomiting, dizziness, and rash. If these side effects occur, they should be reported to a healthcare professional immediately.

Toxicity

Fluorescien is not considered to be a toxic substance, as it is used safely and effectively for medical purposes. However, it should be administered as directed and in the appropriate dosage to avoid any possible adverse reactions.

Precautions

Before using fluorescein, patients should tell their doctor if they have had any prior allergic reactions, if they have any eye diseases, or if they are pregnant or breastfeeding. Patients should avoid contact with the eyes and skin and keep the medication away from children.

Interactions

Fluorescien may interact with certain medications, such as tetracyclines, cephalosporins, penicillins, gentamicin, and chloramphenicol. Patients who are taking any of these medications should inform their doctor before using fluorescein.

Disease Interactions

Fluorescien may not be suitable for patients with certain illnesses, such as multiple sclerosis, diabetes, hepatic or renal impairment, or temperature sensitivity. Patients should inform their doctor of any medical conditions before taking fluorescein.

Drug Interactions

Fluorescien may interact with certain drugs, such as tetracyclines, cephalosporins, penicillins, gentamicin, and chloramphenicol. Patients who are taking any of these medications should inform their doctor before using fluorescein.

Food Interactions

Fluorescien does not interact with food and can be taken with or without meals. However, taking the medication with a meal may decrease its side effects.

Pregnancy and Lactation Use

Fluorescien should be used with caution in pregnant and lactating women, as its effects in these populations have not been studied. Patients should consult their healthcare provider before using this medication while pregnant or breastfeeding.

Acute Overdose

No serious side effects have been reported from an overdose of fluorescein. However, in cases of overdose, patients should seek medical attention immediately.

Contraindications

Fluorescien should not be used in patients with known hypersensitivity to the medication, in patients with multiple sclerosis, diabetes, hepatic or renal impairment, or temperature sensitivity, or in patients using certain drugs, such as tetracyclines, cephalosporins, penicillins, gentamicin, and chloramphenicol.

Use Directions

Fluorescien should be used exactly as prescribed by a healthcare professional. Patients should follow the directions on the label carefully and not take more or less than the recommended dosage. It is important to keep the medication away from children.

Storage Conditions

Fluorescien should be stored in a dry, cool, dark place, away from direct sunlight and heat. It should also be kept away from children.

Volume of Distribution

The volume of distribution (Vd) of fluorescein is not known, as it depends on the patient's condition and losses through metabolism and urinary excretion.

Half Life

The elimination half-life of fluorescein is approximately 0.26 hours, which is the time it takes for fifty percent of the dose to be eliminated from the body.

Clearance

The clearance of fluorescein is about 4 mL/min, which is the rate at which it is eliminated from the body.
