A clinical guide for neurologists and prescribers on helping patients afford Oxtellar XR — covering manufacturer savings programs, PA appeals, and assistance enrollment.

Oxtellar XR's retail price — up to $1,286 per month for some strengths — is a significant barrier for many patients with epilepsy, particularly those with inadequate insurance coverage, high deductibles, or who are uninsured. As the prescribing clinician, you play a crucial role in helping patients access and afford this medication. This guide compiles the most effective savings strategies for providers prescribing Oxtellar XR in 2026.

Understanding the Cost Landscape

Before exploring savings options, it's helpful to know the pricing landscape:

  • Retail cash price: $512–$1,286/month depending on strength and quantity
  • With prescription discount cards: $233–$378 with SingleCare or GoodRx coupons
  • Insurance copay: Varies significantly by plan tier; may require prior authorization
  • With Supernus co-pay card: Up to $250 savings per fill for eligible commercially insured patients
  • Patient assistance (uninsured): No-cost medication through Supernus Support for qualifying patients

Tool 1: Supernus Co-Pay Savings Card

The Oxtellar XR co-pay savings card is the most accessible savings tool for commercially insured patients and cash-paying patients. Key details:

  • Savings of up to $250 per prescription fill
  • Valid for up to 12 prescription fills
  • Available to commercially insured AND cash-paying patients
  • NOT available for Medicare, Medicaid, or other federal/state program beneficiaries

Patients can activate the card online at oxtellarxr.com, by texting SUP to 37500, or by calling Supernus Support at 1-866-398-0833. Consider printing and including co-pay card information with new Oxtellar XR prescriptions.

Tool 2: Supernus Support Patient Assistance Program

For patients who are uninsured or whose insurance does not adequately cover Oxtellar XR, the Supernus Support Patient Assistance Program (PAP) provides no-cost medication. The enrollment process requires your participation as a prescriber:

  1. Download the Supernus Support enrollment form from oxtellarxr.com
  2. Complete and sign the form with the patient
  3. Fax the completed form to 1-855-998-1515
  4. A Supernus Support representative conducts a benefits investigation and determines PAP eligibility
  5. Eligible patients are connected with a designated pharmacy for ongoing supply

Consider assigning a dedicated staff member to manage PAP enrollments — the paperwork burden is manageable but requires consistent follow-through.

Tool 3: Prior Authorization Support and Appeals

Prior authorization (PA) requirements are a significant barrier for some Oxtellar XR patients. When PA is required, Supernus Support offers electronic PA submission through CoverMyMeds. For PA appeals, the strongest documentation includes:

  • History of treatment with generic oxcarbazepine IR and documented reason for switching (adherence failure, peak-level adverse effects)
  • Clinical documentation of seizure control achieved with Oxtellar XR
  • FDA-approved indication: adjunctive therapy for partial-onset seizures in adults and children 6 years and older
  • Peer-reviewed literature supporting the clinical rationale for once-daily dosing (e.g., improved adherence, reduced peak-level side effects)

Tool 4: Prescribe 90-Day Fills to Reduce Per-Dose Cost

For stable patients, prescribing 90-day fills through mail-order pharmacy is one of the most effective cost-reduction strategies. Most commercial insurance plans offer lower copays for mail-order fills, and the per-pill cost is often lower with 90-day quantities. Additionally, mail-order eliminates monthly access challenges for a medication that can be hard to find at retail.

Tool 5: Third-Party Prescription Assistance Organizations

Several third-party organizations help patients navigate pharmaceutical assistance programs:

  • RxAssist.org: Database of pharmaceutical company assistance programs; lists Supernus PAP information
  • NeedyMeds.org: Patient assistance database with income-based eligibility information
  • The Rx Advocates: Advocacy organization that helps patients enroll in manufacturer PAPs for a monthly service fee

When Cost Remains Prohibitive: Discuss Generic Alternatives

If cost remains a barrier even after exploring savings programs, discuss with your patient whether generic oxcarbazepine immediate-release (equivalent to Trileptal) is a clinically appropriate and acceptable alternative. Generic IR oxcarbazepine costs as little as $15–$60/month with a discount card, a fraction of Oxtellar XR's cost. Document the clinical rationale for the formulation choice clearly in the chart — both if you maintain Oxtellar XR for clinical reasons and if you switch to generic IR for cost reasons.

How medfinder Supports Your Patients Beyond Savings

Even when cost is managed, patients still need to find a pharmacy that has Oxtellar XR in stock. medfinder calls pharmacies near your patients to identify which ones can fill the prescription. Directing patients to medfinder can reduce the frustrating search process that sometimes leads to medication gaps — a major safety concern for epilepsy patients.

Frequently Asked Questions

Supernus Pharmaceuticals offers two main programs: (1) Co-pay savings card — up to $250 savings per prescription fill for eligible commercially insured and cash-paying patients, valid for 12 fills; and (2) Patient Assistance Program — no-cost medication for qualifying uninsured or underinsured patients. Contact Supernus Support at 1-866-398-0833 or visit oxtellarxr.com.

Download the Supernus Support enrollment form from oxtellarxr.com, complete it with the patient, and fax it to 1-855-998-1515. A Supernus Support representative will conduct a benefits investigation and determine eligibility. Eligible patients are connected with a designated pharmacy for ongoing supply.

No. The Supernus co-pay savings card is not valid for prescriptions purchased under Medicare, Medicaid, or other federal or state programs. Medicare patients should explore Part D Extra Help (Low Income Subsidy) or state pharmaceutical assistance programs. The Supernus Patient Assistance Program may be available for eligible low-income Medicare patients.

The strongest PA documentation includes: the FDA-approved indication (adjunctive therapy for partial-onset seizures, ages 6+), history of treatment with generic oxcarbazepine IR with documented side effects or adherence failure, clinical evidence of seizure control on Oxtellar XR, and the clinical rationale for once-daily extended-release dosing. Supernus Support can assist with PA submission through CoverMyMeds.

Generic oxcarbazepine immediate-release tablets (equivalent to Trileptal) cost as little as $15–$60 per month with a prescription discount card — a fraction of Oxtellar XR's $500+ retail price. A clinical discussion about formulation equivalence is necessary, as dosage adjustments may be needed when switching. Document the cost-driven formulary substitution in the patient chart.
