While fluorescein is widely used in diagnostic procedures, adverse reactions can occur, with reported rates ranging from 1% to 6%. Understanding **what are the hazards of fluorescein** is crucial for patient safety, especially concerning its intravenous use in procedures like angiography.

According to the US Food and Drug Administration, fluorescein is primarily eliminated via renal excretion within 48 to 72 hours following intravenous administration. This fact leads many to question: **Does fluorescein dye affect the kidneys?** Recent studies suggest it is generally safe, even for patients with chronic kidney disease.

Within one hour of intravenous administration, approximately 80% of fluorescein is converted into its main metabolite, fluorescein monoglucuronide [1.3.1]. This rapid metabolism is the first step in understanding **how is fluorescein excreted** from the body through two primary pathways.

Approximately 80% of an intravenous fluorescein dose is metabolized and converted into fluorescein monoglucuronide within one hour [1.6.2]. Understanding **how long it takes for fluorescein to be eliminated from the body** is key for patients undergoing diagnostic procedures like retinal angiography.
