About Horizant and its cost

What is this medication? Horizant is a prescription medication primarily used to treat adults with moderate-to-severe primary Restless Legs Syndrome, which is a condition characterized by an uncontrollable urge to move the legs due to uncomfortable sensations. It is also approved for the management of postherpetic neuralgia, the persistent nerve pain that can follow a shingles infection. The active ingredient in this medication is gabapentin enacarbil, a prodrug that the body converts into gabapentin to help stabilize nerve activity and reduce the intensity of symptoms.

This medication belongs to a class of drugs known as anticonvulsants and functions by altering how nerves transmit signals to the brain. Although it contains a form of gabapentin, it is specifically designed to be absorbed more efficiently and consistently than traditional gabapentin formulations. It is generally taken once daily for Restless Legs Syndrome or twice daily for nerve pain. Patients are advised to follow their doctors instructions closely and avoid stopping the medication suddenly to prevent potential side effects or a return of symptoms.

Horizant is made by a pharmaceutical manufacturer. Like most brand-name drugs, it's priced at a high list price — but patients rarely pay that list price. The options above are the real paths most people use to get it affordably.

Common questions

What's the cheapest way to afford Horizant?

It depends on your insurance. On Medicare, apply for the manufacturer's Patient Assistance Program (PAP) — it gives the drug free if you meet income requirements. With private insurance, the manufacturer copay card usually drops your copay to $0-$25. Uninsured patients should compare the PAP with Cost Plus Drugs cash price.

Can I use a copay card with Medicare for Horizant?

No — federal law (the Anti-Kickback Statute) prohibits manufacturer copay cards on Medicare, Medicaid, TriCare, and VA prescriptions. But the manufacturer has a separate Patient Assistance Program for Medicare beneficiaries. Check the options above.

Does my Medicare Part D plan cover Horizant?

Part D coverage varies by plan. We query the CMS Prescription Drug Plan file to show you what percentage of plans cover it and at what tier. For your exact copay, pick "Medicare" above and check your plan's Summary of Benefits, or log in to Medicare.gov.

How long does a Patient Assistance Program take?

Most PAPs take 2-6 weeks from application to first fill. Ask the manufacturer about a "bridge supply" — many will ship 30 days free while your application is being reviewed so you don't go without the drug.

What if I have a high-deductible plan?

For generics, Cost Plus Drugs cash price is often cheaper than your deductible-phase copay. For brand names, the manufacturer copay card almost always wins. A GoodRx coupon can be a last resort for uncovered drugs, but it doesn't count toward your deductible.

Are there charity grants for Postherpetic Neuralgia?

Charities like HealthWell Foundation, PAN Foundation, Good Days, and the National Organization for Rare Disorders provide copay help for specific conditions. Funds often run out mid-year — apply early. We list the specific grants for your condition in the options above.
