About Keveyis and its cost

What is this medication? Keveyis is a prescription drug specifically indicated for the treatment of primary periodic paralysis, which includes conditions such as hypokalemic periodic paralysis and hyperkalemic periodic paralysis. These are rare genetic disorders that cause episodes of severe muscle weakness or temporary paralysis. By taking this medication regularly, patients can reduce the frequency and severity of these episodes, helping them maintain better physical function and muscle strength over time.

The active ingredient in this medication is dichlorphenamide, which belongs to a class of drugs known as carbonic anhydrase inhibitors. It works by regulating the balance of fluids and electrolytes in the body, although the exact way it prevents muscle weakness in periodic paralysis is not fully understood. It is typically taken in tablet form as directed by a healthcare provider. Patients should be monitored for potential side effects such as tingling sensations, cognitive changes, or changes in potassium levels while using this treatment.

Keveyis is made by Xeris. 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 Keveyis?

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 Keveyis?

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

Does my Medicare Part D plan cover Keveyis?

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 Periodic Paralysis?

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.
