How to Save Money on Furosemide in 2026: Coupons, Discounts, and Patient Assistance

Here's the good news about furosemide and cost: it's one of the cheapest prescription medications in the United States. The generic version is available for as little as $1.80 per 30-day supply with the right discount card. Even without insurance or discounts, most patients pay between $10 and $25 a month. But if you're looking to pay as little as possible—or if you're uninsured—here's everything you need to know.

What Does Furosemide Cost Without Insurance?

The average retail price of generic furosemide varies by strength and pharmacy, but here are typical cash prices for a 30-day supply:

20 mg tablets: Average retail ~$10–$20

40 mg tablets: Average retail ~$10–$25

At Costco and Walmart, generic furosemide often costs under $10 for a 30-day supply without any coupon

If you take furosemide twice daily, your monthly cost for medication is roughly doubled. At maximum doses (e.g., 80 mg twice daily for resistant fluid overload), costs can approach $35–$50 per month without insurance or discounts—but these higher doses are less common.

How to Get Furosemide for Under $5 a Month

Prescription discount programs can dramatically reduce the cost of generic furosemide—often to less than $5 for a 30-day supply:

GoodRx: As low as $1.80 for 30 tablets (generic). Available at CVS, Walgreens, Walmart, and most major pharmacies. No signup required for the basic coupon.

SingleCare: As low as $2.80 for 30 tablets of generic furosemide 20 mg. Free to use at most chain pharmacies.

RxSaver / Blink Health: Additional discount platforms that may offer competitive prices—always compare before filling.

Mark Cuban's Cost Plus Drugs: costplusdrugs.com offers transparent low pricing on generic medications. Furosemide is frequently available at very low cost here. Requires mail delivery.

Tip: Don't use your insurance if your out-of-pocket coupon price is cheaper. You cannot use a coupon and insurance together at the same pharmacy transaction. Always compare the coupon price vs. your insurance copay.

Furosemide With Insurance

Generic furosemide is covered by virtually every commercial insurance plan, Medicare Part D, Medicaid, TRICARE, and the VA. It is typically placed on Tier 1 (the lowest copay tier), meaning most insured patients pay $0–$10 per month. If your plan places it at a higher tier, appeal the tier placement or ask your doctor for a medical necessity letter.

Medicare Part D: Furosemide is on virtually every Part D formulary at Tier 1–2. The 2026 annual out-of-pocket cap is $2,100. Furosemide alone is unlikely to contribute significantly to this cap given its low cost.

Medicaid: Covered in all states. Copay is typically $0–$3 depending on your state's program.

What About Brand-Name Lasix?

Brand-name Lasix is rarely stocked and significantly more expensive than generic furosemide. There is no clinically meaningful difference between generic furosemide and brand-name Lasix—they contain the same active ingredient in the same dose. Most doctors and pharmacists will substitute generic furosemide automatically unless you specifically request the brand name.

What About Furoscix (Subcutaneous Furosemide)?

Furoscix (furosemide subcutaneous injection, 80 mg/10 mL) is a newer, significantly more expensive formulation. It is used for at-home management of heart failure fluid overload and is typically covered by insurance for qualified patients. The out-of-pocket cost without insurance is substantially higher than oral generic furosemide. Patients prescribed Furoscix should contact their insurance company about prior authorization requirements.

Is There Patient Assistance for Furosemide?

Because generic furosemide is already extremely affordable (under $5/month with discounts), formal manufacturer patient assistance programs are not typically offered for the generic version. However, if cost is still a barrier, these resources can help:

NeedyMeds.org: Lists available financial assistance programs for medications by drug name

Partnership for Prescription Assistance (PPA): Connects uninsured and underinsured patients with assistance programs

Community health centers: Federally Qualified Health Centers (FQHCs) offer sliding-scale fee prescriptions and in-house pharmacies for low-income patients

Tips for Saving the Most on Furosemide

Always compare your insurance copay vs. GoodRx or SingleCare prices—coupons often beat Tier 1 copays.

Ask for a 90-day supply—most plans and discount programs offer a lower per-pill price for 90-day fills.

Check Costco and Walmart pharmacy prices—they often carry generic furosemide at very low cash prices without any coupon.

Try mail-order through Cost Plus Drugs or your insurance's preferred mail-order pharmacy for the lowest per-dose price.

If cost and availability are both concerns, medfinder can help you find the nearest pharmacy that has furosemide in stock so you don't waste time driving to locations that are out.
