The FDA has approved Furoscix (scPharmaceuticals), a subcutaneous formulation of the loop diuretic furosemide administered via a single-use, on-body infusor, for treatment of congestion due to fluid overload in adults with New York Heart Association (NYHA) Class II-III chronic heart failure (HF). Furosemide (Lasix, and generics) has been available for years in oral and IV formulations.

Pharmacologic management of chronic heart failure (HF) is primarily determined by the patient's left ventricular ejection fraction (LVEF) and severity of symptoms. Patients with chronic HF who have an LVEF ≤40% are considered to have heart failure with reduced ejection fraction (HFrEF) and those with an LVEF ≥50% are considered to have heart failure with preserved ejection fraction (HFpEF). Patients with an LVEF of 41-49% have heart failure with mildly reduced or mid-range ejection fraction.

American College of Cardiology/American Heart Association (ACC/AHA) guidelines for treatment of hypertension were last published in 2018. Treatment of hypertensive urgencies and emergencies is not discussed here.
