The most common minor side effect reported after flumazenil administration in anesthesia is which?

• A. Nausea and/or vomiting
• B. Dizziness
• C. Tremors
• D. Hypertension

Answer: (A)

Flumazenil rapidly reverses benzodiazepine effects by blocking GABA-A receptors, so you often see a quick return of wakefulness with only mild, transient adverse effects. The most common minor side effect after this reversal is nausea and/or vomiting. This GI upset tends to be more frequent than other mild effects because reversing CNS depression can be accompanied by a brief, nonspecific irritative response and heightened GI activity in the immediate postoperative period. Dizziness and tremors can occur but are less common, and hypertension is also possible but not as typical as nausea/vomiting. In patients with chronic benzodiazepine use, flumazenil can precipitate withdrawal with agitation, tachycardia, or hypertension, but those are more concerning and not the typical minor, everyday side effect.
