When administering IV push furosemide (Lasix), how long should it be given to avoid tinnitus?

Administering IV push furosemide (Lasix) over the recommended time frame is essential to minimize the risk of ototoxicity, which can lead to tinnitus or hearing loss. The correct duration for administration is two minutes, as this allows the drug to be delivered at a rate that reduces the likelihood of adverse effects on the auditory system.

Furosemide is a potent loop diuretic that, when given too quickly, can cause a rapid increase in serum levels. This spike in concentration can overwhelm the body's ability to process the drug safely, leading to potential damage to the auditory structures. By adhering to the guideline of administering it over a two-minute period, healthcare providers can help mitigate these risks and ensure a safer experience for the patient.

Other durations listed may not align with established safe practices. Administering furosemide for shorter times may not allow for adequate absorption and may increase the likelihood of side effects, including tinnitus. Therefore, the two-minute guideline is critical for optimal safety and efficacy in IV push administration of furosemide.
