From the Guidelines
For a patient with CHF exacerbation requiring outpatient management with Lasix (furosemide), I recommend starting with Lasix 20-40mg daily, titrating up as needed based on symptoms and fluid status, as this approach is supported by the most recent and highest quality study 1. The outpatient plan should include:
- Daily weight monitoring (same time, same clothes), with instructions to call if weight increases by 2-3 pounds in a day or 5 pounds in a week
- Fluid restriction to 1.5-2 liters daily and sodium restriction to 2-3 grams daily, as these measures are essential for reducing fluid overload and preventing worsening heart failure 1
- Monitoring for signs of worsening heart failure (increased shortness of breath, orthopnea, peripheral edema) and Lasix side effects (dizziness, excessive urination, electrolyte imbalances)
- Regular follow-up within 1-2 weeks is necessary to assess response and check electrolytes, particularly potassium and renal function, as Lasix can cause hypokalemia and worsen renal function 1
- Medication adherence should be emphasized, and the patient should continue all other heart failure medications as prescribed
- Patient education about activity pacing, elevating legs when sitting, and sleeping with head elevated may also improve symptoms It is crucial to note that the dose of Lasix may need to be adjusted based on the patient's response, and the ultimate goal of diuretic treatment is to eliminate clinical evidence of fluid retention, as stated in the 2013 ACCF/AHA guideline for the management of heart failure 1.
From the FDA Drug Label
INDICATIONS AND USAGE Edema Furosemide tablets are indicated in adults and pediatric patients for the treatment of edema associated with congestive heart failure, cirrhosis of the liver, and renal disease, including the nephrotic syndrome. The patient with CHF exacerbation can be treated with furosemide (Lasix) as part of the outpatient plan of care, as it is indicated for the treatment of edema associated with congestive heart failure 2. Key considerations for the outpatient plan of care include:
- Monitoring for signs of fluid or electrolyte imbalance
- Regular laboratory tests, such as serum electrolytes and renal function
- Patient education on symptoms of excessive fluid and/or electrolyte losses and the importance of adherence to the treatment plan.
From the Research
CHF Exacerbation and Lasix Prescription
- CHF exacerbation is a serious condition that requires prompt treatment, and Lasix (furosemide) is a commonly prescribed diuretic for managing fluid overload and edema in patients with congestive heart failure 3.
- The combination of a diuretic and an ACE inhibitor is currently the proper treatment of congestive heart failure, with a beta-blocker added in selected patients 4.
Outpatient Plan of Care
- The choice of diuretic is essential for successful management of heart failure and is mainly guided by patient clinical situations and the presence of other co-morbidities 3.
- Beta-blockers and ACE inhibitors are commonly used in combination to manage heart failure, with beta-blockers reducing mortality and hospitalization, and ACE inhibitors providing cardioprotection and reducing symptoms 5, 4, 6.
- The combination of beta-blockers and ACE inhibitors can be used across the spectrum of cardiovascular diseases, including hypertension, heart failure, and coronary artery disease 6.
- Regular monitoring of patients with heart failure is crucial to adjust treatment plans and prevent exacerbations, with considerations for diuretic therapy, beta-blockers, and ACE inhibitors 4, 3, 6.
