What is the most common side effect associated with intravenous administration of sodium fluorescein?

The most common side effect associated with intravenous administration of sodium fluorescein is nausea and vomiting. This reaction can occur due to the body’s sensitivity to the dye itself. When sodium fluorescein is injected, it can stimulate the chemoreceptor trigger zone in the brain, leading to feelings of nausea and the possibility of vomiting.

While elevated temperature, bronchospasm, and anaphylaxis are potential side effects of sodium fluorescein, they are significantly less common than nausea and vomiting. Elevated temperature may occur due to various factors but is not specific to fluorescein use. Bronchospasm is a more serious respiratory reaction, but it is relatively rare in the context of fluorescein administration. Anaphylaxis, though it is a serious allergic reaction that can happen, is an uncommon response to sodium fluorescein.

Recognizing nausea and vomiting as the most prevalent side effect helps practitioners to inform and prepare patients prior to the administration of this intravenous dye, ensuring they are aware of the potential for experiencing these symptoms during or after the test.
