What to prescribe for a patient with peripheral edema (foot swelling) without hypertension (HTN)?

From the Guidelines

For a patient with peripheral edema without hypertension, I would recommend starting with lifestyle modifications and compression-based therapies, such as graduated stockings and intermittent compression, as they have a low risk of harm and the possibility of benefit, as suggested by the American Heart Association 1. When managing peripheral edema without hypertension, it's essential to consider the underlying cause of the edema.

• If the edema is secondary to an underlying condition such as venous insufficiency, liver disease, or heart failure, addressing the primary cause is crucial for effective management.
• Lifestyle modifications are also crucial, including:
  • Reducing salt intake to less than 2g per day
  • Elevating the affected limbs when sitting or lying down
  • Wearing compression stockings
  • Maintaining regular physical activity These modifications can help reduce fluid volume in the body and consequently decrease edema. Although diuretics, such as thiazide or loop diuretics, may be considered in some cases, they should be used with caution and under close monitoring, as they can cause electrolyte imbalances and other adverse effects. In the absence of strong evidence supporting the use of diuretics in this specific context, compression-based therapies, such as graduated stockings and intermittent compression, are a reasonable initial approach, as they have a low risk of harm and the possibility of benefit, as suggested by the American Heart Association 1.

From the FDA Drug Label

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 has peripheral edema (foot swelling) without hypertension, furosemide can be prescribed for the treatment of edema.

• The primary indication for furosemide is edema associated with various conditions.
• Key point: Furosemide can be used to treat edema in patients without hypertension 2.

From the Research

Treatment Options for Peripheral Edema without Hypertension

• For patients with peripheral edema without hypertension, diuretics can be considered as a treatment option 3, 4, 5.
• Furosemide is a commonly used diuretic for treating peripheral edema, and it can be effective in reducing swelling and improving symptoms 3, 4, 5.
• Combination therapy with compression bandaging and diuretics, such as furosemide, may be beneficial for patients with refractory edema 3.
• High-dose furosemide and small-volume hypertonic saline solution infusion may also be an effective strategy for treating peripheral edema in patients with advanced cancer 4.
• However, diuretic therapy should be used with caution, as it can cause electrolyte disturbances, particularly in patients with renal insufficiency or those taking other medications 6.

Considerations for Diuretic Therapy

• Patients with peripheral edema without hypertension may require higher doses of diuretics to achieve adequate diuresis 7.
• The choice of diuretic and dosage should be individualized based on the patient's underlying condition, renal function, and other medications 7.
• Monitoring of electrolyte levels, renal function, and blood pressure is essential during diuretic therapy to minimize the risk of adverse effects 6, 7.
• Combination therapy with other medications, such as digitalis or angiotensin-converting enzyme inhibitors, may be necessary to overcome diuretic resistance in some patients 7.
