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

Onfi is a critical medication for patients with Lennox-Gastaut syndrome — but it can be shockingly expensive without the right strategy. Brand-name Onfi retails for $745 to over $1,000 per month at many pharmacies. Even generic clobazam can run $30–$150 for a 30-day supply depending on your dose and pharmacy. For a medication you take every day for life, those costs add up fast.

The good news: there are multiple ways to significantly reduce what you pay for Onfi or clobazam. This guide covers every savings option available in 2026.

Step 1: Switch to Generic Clobazam (Biggest Savings)

If you're still taking brand-name Onfi, switching to generic clobazam is the single most impactful cost-saving move you can make. Generic clobazam is FDA-approved as therapeutically equivalent to Onfi — it contains the same active ingredient at the same doses and is approved to the same quality standards.

The cost difference is dramatic: brand Onfi can cost $745–$1,000+ per month at retail, while generic clobazam typically costs $30–$150 per month — a savings of $600–$900 or more for the same medication. Ask your doctor to prescribe clobazam generically if they haven't already.

Step 2: Use a Prescription Discount Card

Even on generic clobazam, prescription discount cards can meaningfully reduce your out-of-pocket cost. These cards are free to obtain and are accepted at most major pharmacies:

• GoodRx: Can bring the price of generic clobazam to as low as $26.20 (96% off the average retail price of ~$745). GoodRx Gold, a membership program, offers prices as low as $21.13.
• SingleCare: Competitive pricing often in the $50–$90 range for generic clobazam; accepted at CVS, Walgreens, Walmart, and most major chains. SingleCare lists generic Onfi for as low as $18.35.
• RxSaver: Compares prices across multiple discount programs; worth checking alongside GoodRx and SingleCare, as the best price varies by pharmacy and location.

Pro tip: Always compare prices across at least 2–3 discount cards before filling your prescription. Prices can differ by $20–$40 or more between cards at the same pharmacy.

Step 3: Patient Assistance Programs (For Uninsured or Underinsured Patients)

If you're uninsured or underinsured and struggling to afford clobazam, patient assistance programs (PAPs) may provide the medication at low or no cost:

• Lundbeck Patient Assistance Program (for Onfi): Lundbeck, the manufacturer of brand-name Onfi, offers a patient assistance program for eligible patients. Requirements typically include U.S. residency, no or inadequate prescription drug coverage, and income below a threshold (often 300–400% of the federal poverty level). Contact Lundbeck at 1-800-455-1141 or visit onfi.com.
• Aquestive Therapeutics (for Sympazan): Offers savings and access programs for Sympazan. If your doctor recommends the oral film formulation, check with Aquestive about available copay assistance.
• NeedyMeds: A nonprofit database of patient assistance programs, discount drug cards, and other resources. Search for clobazam at needymeds.org to find all available programs.
• Epilepsy Foundation: Provides resources including medication assistance programs, connections to local affiliate chapters, and a helpline (1-800-332-1000) for patients navigating access issues.

Step 4: Maximize Your Insurance Benefits

If you have insurance, generic clobazam is typically covered on Tier 1 or 2 of most formularies, resulting in a $0–$30 copay. A few strategies to minimize your insurance-based costs:

• Use your plan's preferred pharmacy: Many insurance plans offer lower copays at preferred network pharmacies. Check your plan's formulary.
• Request a 90-day supply: A 90-day supply filled through mail order or a preferred retail pharmacy often has a lower per-dose cost than three separate 30-day fills. It also reduces the chance of running into supply gaps.
• Appeal prior authorization denials: If brand Onfi or Sympazan requires prior authorization and is denied, ask your neurologist to submit a prior auth appeal with clinical justification. The Lundbeck support team (1-800-455-1141) can assist with this process.

What Does Onfi Cost With and Without Insurance in 2026?

Here's a quick cost comparison:

• Brand Onfi retail (no insurance): $745–$1,000+ per month
• Generic clobazam retail (no insurance): $30–$150 per month
• Generic clobazam with GoodRx/SingleCare: $18–$90 per month
• Generic clobazam with most commercial insurance: $0–$30 copay
• Generic clobazam on Medicare Part D: typically covered; copay varies by plan

The Bottom Line on Saving Money on Onfi

The cheapest path to clobazam in 2026 is: generic clobazam + a GoodRx or SingleCare coupon, which can bring the cost to $18–$90 per month. If you're uninsured, Lundbeck's PAP is worth applying for. And if you're struggling to find your medication at all, medfinder can help you locate pharmacies near you that have it in stock.
