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

Metronidazole is one of the most affordable prescription antibiotics available in the United States. The generic form — sold under brand names like Flagyl — has been off-patent since 1982, which means multiple manufacturers compete to produce it and prices have dropped dramatically. Even without insurance, most patients pay well under $30 for a full course of treatment.

Here's everything you need to know to pay as little as possible for metronidazole in 2026.

How Much Does Metronidazole Cost Without Insurance?

The average retail cash price for 14 tablets of generic metronidazole 500 mg is approximately $22–$28 at most pharmacies. With a discount coupon, the cost can fall dramatically:

Average retail price: ~$22.69 for 14 x 500 mg tablets (GoodRx reported average)

With GoodRx coupon: As low as $3.93 — that's an 83% savings off the retail price

With SingleCare coupon: Average retail without insurance is ~$27.68; coupon prices vary by pharmacy

Walmart $4 program: Metronidazole has historically been included in Walmart's $4 generic drug program for standard quantities

How Much Does Metronidazole Cost With Insurance?

Most insurance plans — including Medicare Part D, Medicaid, and commercial plans purchased through the ACA marketplace — cover generic metronidazole. It is typically placed on Tier 1 (preferred generic), meaning your copay is usually minimal:

Tier 1 copay (most plans): $0–$15 per prescription

Medicare Part D: Covered by nearly all Part D plans. Copay typically $0–$5 for Tier 1 generics.

Medicaid: Covered in virtually all state Medicaid programs. Minimal or no copay depending on the state.

Important tip: Sometimes a GoodRx or SingleCare coupon is actually cheaper than your insurance copay. It's always worth checking your coupon price before using your insurance card — pharmacies are required to allow this comparison.

Step-by-Step Guide to Getting the Lowest Price on Metronidazole

Always ask for generic metronidazole: Brand-name Flagyl costs significantly more than the generic equivalent. If your prescription says "Flagyl" without "brand necessary," ask for generic.

Download a free discount card: GoodRx (goodrx.com) and SingleCare (singlecare.com) both offer free downloadable coupons or discount cards. Search for "metronidazole 500 mg" and your zip code to find the cheapest pharmacy near you. GoodRx shows prices as low as $3.93.

Compare prices at multiple pharmacies: GoodRx and SingleCare let you compare prices across pharmacies in your area side-by-side. The price difference between the most expensive and cheapest pharmacy can be $10–$20 for the same medication.

Check Walmart, Kroger, and Publix: These grocery-store pharmacies often have lower base prices than chain pharmacies. Walmart's $4 generic program and Publix's free antibiotic program (which historically included metronidazole in some states) can reduce costs to near zero.

Check if your insurance covers it before paying cash: Ask the pharmacist to run the prescription through your insurance first and show you the copay. Then compare that number to the GoodRx or SingleCare price. Pay whichever is lower.

Is There a Manufacturer Savings Program for Metronidazole?

Because metronidazole is a generic drug made by multiple manufacturers, there is no branded manufacturer savings program like those offered for brand-name specialty drugs. However, the combination of generic pricing and third-party discount coupons means most patients can access it for under $10 — making additional assistance programs largely unnecessary for this particular medication.

For uninsured patients with very low income, community health centers (FQHCs — federally qualified health centers) often provide prescriptions at sliding-scale fees, and some may provide the medication directly.

What About Topical Metronidazole (Metrogel, Metrocream)? Is That Expensive?

Topical metronidazole formulations used for rosacea (Metrogel, Metrocream, Metrolotion) are significantly more expensive than oral forms. The average retail price for topical metronidazole gel (1%) is roughly $92–$183 depending on the formulation. With GoodRx, prices can drop to $16–$55. Generic topical equivalents are more affordable than brand-name versions.

If you're using topical metronidazole for rosacea and cost is a concern, ask your dermatologist whether a generic version is appropriate and use a GoodRx coupon to compare pharmacy prices.
