How to Save Money on Nitrofurantoin in 2026

If you've been prescribed Nitrofurantoin (brand names Macrobid and Macrodantin) for a urinary tract infection, here's the good news: this is one of the most affordable antibiotics available — especially if you know where to look for savings. Here's everything you need to know about the cost of Nitrofurantoin and how to pay less.

How Much Does Nitrofurantoin Cost Without Insurance?

The price of Nitrofurantoin varies widely depending on the formulation, pharmacy, and whether you use a discount card:

• Generic Nitrofurantoin capsules (average retail): Approximately $43 for a typical 5-7 day course
• Generic with discount coupons: As low as $3-$10 at participating pharmacies
• Brand-name Macrobid (100 mg capsules): $50-$200+ without insurance or coupons
• Brand-name Macrodantin: $44-$150+ without insurance
• Oral suspension (Furadantin): Pricing varies; may be more expensive due to limited availability

The bottom line: if you're paying more than $15 for generic Nitrofurantoin, you're likely paying too much. Discount coupons can save you up to 78% off the retail price.

Coupons and Discount Cards

Free prescription discount cards are one of the easiest ways to save on Nitrofurantoin. These programs are not insurance — they're free to use, require no sign-up in most cases, and work at most major pharmacies. Here are the top options:

GoodRx

GoodRx consistently offers some of the lowest prices for generic Nitrofurantoin. As of 2026:

• Generic Nitrofurantoin mono/macro 100 mg: Starting around $3-$10 for a 10-capsule supply (5-day course)
• Compare prices across nearby pharmacies on goodrx.com or the GoodRx app
• Free to use — just show the coupon at the pharmacy counter

SingleCare

SingleCare is another excellent option, sometimes offering even lower prices than GoodRx at certain pharmacies:

• Generic Nitrofurantoin: Starting around $5-$12 depending on the pharmacy
• Accepted at CVS, Walgreens, Walmart, and most independent pharmacies
• No membership required

RxSaver

RxSaver (by RetailMeNot) compares prices across multiple discount programs:

• May find prices as low as $4-$9 at select pharmacies
• Useful for comparing across discount programs to find the absolute lowest price

Other Discount Programs

Additional options worth checking:

• Optum Perks — competitive pricing on generics
• BuzzRx — often good prices at independent pharmacies
• America's Pharmacy — another free discount card option
• Walmart $4 prescriptions — check if Nitrofurantoin is on their discount list

Pro tip: Prices vary significantly between pharmacies, even with the same coupon. Always compare at least 3-4 pharmacies before filling. Costco and Walmart often have the lowest base prices.

Patient Assistance Programs

If you're uninsured or underinsured and struggling to afford your medications, these resources may help:

NeedyMeds

NeedyMeds maintains a database of patient assistance programs, discount coupons, and state-by-state pharmaceutical assistance programs. While there isn't a dedicated manufacturer assistance program for generic Nitrofurantoin, NeedyMeds can connect you with general programs that may help cover costs.

RxAssist

RxAssist is a comprehensive database of patient assistance programs. Search for Nitrofurantoin to find available options based on your income and insurance status.

State Pharmaceutical Assistance Programs (SPAPs)

Many states offer programs that help residents pay for prescription medications. Eligibility varies by state, income, and age. Check your state's health department website for details.

Community Health Centers

Federally Qualified Health Centers (FQHCs) can provide medications at reduced costs through the 340B drug pricing program. If you receive care at a community health center, ask about discounted pharmacy services.

Other Ways to Save

Always Choose Generic

Generic Nitrofurantoin is identical to brand-name Macrobid and Macrodantin in terms of active ingredient, dosage, and effectiveness. The difference is price: generic can be $3-$10 vs. $50-$200+ for brand name. Unless your doctor specifies "brand name only" (which is rare for Nitrofurantoin), always accept the generic.

Use Insurance — But Compare First

If you have insurance, Nitrofurantoin is typically covered as a Tier 1 (preferred generic) medication with copays of $0-$15. However, sometimes a discount coupon can actually beat your insurance copay — especially at pharmacies like Costco or Walmart. It's worth comparing both options before paying.

Ask About 90-Day Supplies for Prophylaxis

If you take Nitrofurantoin daily for UTI prevention (prophylaxis), ask your doctor about a 90-day prescription. Many pharmacies and insurance plans offer lower per-unit pricing for 90-day supplies, and mail-order pharmacies may offer additional savings.

Shop Around

Prescription prices can vary by $30 or more between pharmacies in the same zip code. Use GoodRx, SingleCare, or Medfinder to compare prices before you fill. Don't assume your regular pharmacy has the best price.

Final Thoughts

Nitrofurantoin is already one of the most affordable antibiotics available, and with discount coupons, most patients can fill a prescription for under $10. Don't pay full retail price when free savings tools are available.

Here's your savings checklist:

1. Always ask for generic Nitrofurantoin
2. Compare prices on GoodRx, SingleCare, and RxSaver before filling
3. Check whether a discount coupon beats your insurance copay
4. Try Costco, Walmart, or independent pharmacies for the lowest prices
5. If uninsured, explore NeedyMeds and RxAssist for assistance
