Side effects
Monitor
- Potassium before dose — chase the K if it's low and there's no replacement order
- Daily weight, strict I&O, orthostatic BP
- IV push SLOWLY (typically ≤ 10 mg/min furosemide) — fast push risks hearing damage
- Urine output response — no response is reportable
🎓 Patient teaching
Take in the morning (or you'll be up all night). Eat potassium foods unless told otherwise. Daily weight; report 2–3 lb overnight gain.
