Furosemide Shortage Update: What Patients Need to Know in 2026

Furosemide—the generic form of Lasix—is one of the most prescribed diuretics in the United States. With more than 19 million prescriptions dispensed in 2023 alone, it's a critical medication for millions of Americans managing heart failure, kidney disease, and high blood pressure. When reports of shortage surface, patients and caregivers understandably worry. Here's a clear, factual breakdown of what's happening in 2026.

Current Status: Furosemide Oral Tablets (2026)

Oral furosemide tablets (20 mg, 40 mg, 80 mg) are NOT on the FDA's active shortage list in 2026. The generic tablet is manufactured by multiple companies and is generally widely available at most retail pharmacies. If your local pharmacy is out of stock, a nearby pharmacy almost certainly has it.

However, patients occasionally report difficulty filling specific strengths (particularly 20 mg and 80 mg tablets) at specific locations. This reflects localized stock variation rather than a national supply crisis.

Current Status: Furosemide Injection (2026)

Injectable furosemide (10 mg/mL for IV and IM use) has a more complex availability picture. Manufacturers including Hikma have reported backorders on vials in late 2025 and early 2026. This form is critical for hospitalized patients with severe heart failure, acute pulmonary edema, and kidney crises. Hospital pharmacies and clinical settings have been managing with available supply and, where necessary, substituting other loop diuretics.

The FDA's drug shortage database lists furosemide injection as a drug with current shortage status as of early 2026. Patients receiving IV furosemide in a hospital or clinical setting should speak with their care team about the latest availability.

Why Does Furosemide Injection Keep Going on Shortage?

Sterile injectable drugs like furosemide IV are among the most vulnerable to shortage. Here's why:

Manufacturing complexity: Producing sterile injectables requires specialized facilities with strict contamination controls. There are fewer manufacturers capable of making them.

FDA quality inspections: When the FDA identifies quality issues at an injectable facility, production may be halted or reduced, immediately affecting national supply.

Low profit margins: Generic injectable furosemide is inexpensive, making it less profitable for manufacturers. This reduces incentive to expand capacity or maintain buffer stock.

Demand surges: Acute heart failure hospitalizations can spike during flu season and heat waves, rapidly drawing down available injectable stock.

Historical Context: Furosemide Shortage Timeline

Furosemide injection has appeared on FDA shortage lists multiple times over the past decade. Each shortage has prompted hospitals to use alternative loop diuretics, primarily torsemide and bumetanide. The oral tablet form, by contrast, has remained largely stable thanks to multiple manufacturers and simpler production requirements.

One major concern highlighted by medication safety researchers: when hospitals switch from furosemide IV to bumetanide IV, the 40:1 potency difference has caused medication errors. Healthcare institutions have implemented strict protocols to prevent dosing mistakes during shortage-related switches.

What About the Furoscix Subcutaneous Option?

Furoscix is a subcutaneous furosemide delivery system (80 mg/10 mL kit) designed for at-home use by heart failure patients who need diuretic therapy between hospital visits. It was developed partly in response to the limitations of IV-dependent treatment. If you are prescribed Furoscix and have trouble finding it, ask your prescriber about specialty pharmacy options—Furoscix is not typically stocked at retail pharmacies.

What Patients Should Do Right Now

If you take oral furosemide: You are unlikely to face a serious shortage. Refill a few days early, check multiple pharmacies if your current one is out, and consider a 90-day mail-order supply.

If you receive IV furosemide in a clinical setting: Your hospital pharmacy team is managing supply and will notify your care team of any changes. Discuss your concerns with your doctor or nurse.

If you can't fill your oral prescription: Call multiple pharmacies or use medfinder to search for availability near you. Ask your doctor about alternative loop diuretics as a bridge.

Do NOT stop taking furosemide without consulting your doctor—especially if you have heart failure. Missing doses can cause dangerous fluid buildup.

How to Check the Current Shortage Status

For the most up-to-date information, check the FDA's official Drug Shortages Database at fda.gov/drugs/drug-safety-and-availability/drug-shortages. The ASHP (American Society of Health-System Pharmacists) also maintains a comprehensive drug shortage database at ashp.org/drug-shortages.

If you're having trouble finding furosemide at your local pharmacy, medfinder can call pharmacies near you to locate which ones have your medication in stock and text you the results.
