Zarontin (ethosuximide) can cost $200–$580 without insurance. Here's how to save money with GoodRx, SingleCare, insurance tips, and Pfizer RxPathways in 2026.

Zarontin (ethosuximide) is a life-essential medication for patients with absence epilepsy. But without the right cost strategy, it can be surprisingly expensive. The cash price can run from $200 to over $580 per month. The good news: with the right approach, many patients can pay far less—sometimes under $35 per month for generic ethosuximide.

Here is a complete 2026 guide to every available option for reducing the cost of Zarontin.

How Much Does Zarontin Cost in 2026?

Prices vary significantly by formulation and pharmacy:

Brand Zarontin (oral solution, Pfizer): Approximately $579.83 retail without insurance
Generic ethosuximide capsules (average retail): Approximately $200–$215 without insurance
With GoodRx coupon: As low as $33.61 for generic ethosuximide (84% off average retail)
With SingleCare coupon: As low as $35.88 for generic ethosuximide

Option 1: Use a GoodRx Coupon

GoodRx is one of the most effective tools for reducing the cost of generic ethosuximide. Here's how to use it:

Visit GoodRx.com and search for "ethosuximide"
Enter your dose and quantity (e.g., 250 mg, 100 capsules)
Enter your ZIP code to find pharmacies near you with the lowest price
Download or print your coupon
Show the coupon at the pharmacy counter when picking up your prescription

GoodRx prices vary by pharmacy location. The $33.61 price is for the most common version (generic ethosuximide) at participating pharmacies. Prices are updated regularly.

Option 2: Use a SingleCare Coupon

SingleCare is another popular discount card option. Visit SingleCare.com, search for Zarontin, and compare prices at pharmacies near you. For 120 generic ethosuximide capsules (250 mg), SingleCare prices can be as low as $35.88. Like GoodRx, SingleCare works regardless of your insurance status and can sometimes be used even if you have insurance, depending on which price is lower.

Option 3: Use Your Insurance Plan

Most commercial insurance plans and Medicare Part D cover generic ethosuximide as a preferred generic at Tier 1 or Tier 2, with typical copays of $10 to $50 per month. Important notes:

Generic ethosuximide is usually covered without prior authorization on most plans
Brand-name Zarontin may require prior authorization—your prescriber can submit a PA request if medically necessary
Medicare Part D and Medicare Advantage plans cover generic ethosuximide but generally do NOT cover brand-name Zarontin
Always compare your insurance copay to the GoodRx price—sometimes the discount card is cheaper even than your copay

Option 4: Pfizer RxPathways Patient Assistance Program

Pfizer, the manufacturer of brand-name Zarontin, offers the RxPathways Patient Assistance Program for qualifying patients. As of 2026:

Eligible patients: Uninsured or government-insured (Medicare, Medicaid, TRICARE/VA) with annual pre-tax household income at or below 300% of the Federal Poverty Level
Benefit: May provide Zarontin at no cost
How to apply: Call 1-844-989-7284 (1-844-989-PATH) or visit PfizerRxPathways.com
Note: Commercially insured patients are not eligible for the PAP

Option 5: Order a 90-Day Supply

Many pharmacies and GoodRx offer lower per-pill pricing when you fill a 90-day supply instead of a 30-day supply. If your prescriber writes for a 90-day quantity and your insurance permits it, this can reduce your overall cost. Mail-order pharmacies often offer the best pricing on 90-day supplies.

Option 6: NeedyMeds and Other Assistance Programs

Third-party organizations such as NeedyMeds (needymeds.org) and RxOutreach maintain databases of patient assistance programs. While these are primarily useful for brand-name medications, they may have options for patients who do not qualify for Pfizer's program but still face financial hardship.

Summary: Zarontin Cost Comparison for 2026

Uninsured, using GoodRx: As low as $33.61/month for generic
With insurance (generic, Tier 1): $10–$50 copay/month
Pfizer RxPathways (if eligible): Possibly free
Brand Zarontin, no discount: ~$579.83/month
