Is Kesimpta in shortage in 2026? Get the latest update on Kesimpta availability, why it's hard to find, what it costs, and how to get your prescription filled.
If you're having trouble getting your Kesimpta (Ofatumumab) prescription filled, you're probably wondering: is there an actual shortage? The short answer is no — as of early 2026, the FDA has not listed Kesimpta on its official drug shortage database.
But that doesn't mean it's easy to find. Many patients with relapsing multiple sclerosis report frustrating delays in accessing Kesimpta, and those delays can feel a lot like a shortage when you're waiting for a medication you need to stay healthy. Let's break down what's actually going on.
Even without a formal shortage, several factors make Kesimpta difficult to access:
Kesimpta is a biologic medication that must be stored at 36°F to 46°F and handled through cold-chain logistics. It's not stocked at standard retail pharmacies. Instead, it's dispensed through specialty pharmacies — a smaller network of pharmacies equipped to handle complex biologics. If you're looking for Kesimpta at your local drugstore, you won't find it there.
Most insurance plans require prior authorization for Kesimpta, and many also impose step therapy requirements, meaning you may need to try and fail on a less expensive MS therapy before Kesimpta is approved. These processes can take days to weeks, creating gaps between when you need the medication and when you can actually get it.
At a list price of approximately $6,800 to $7,500 per monthly injection — roughly $82,000 to $90,000 per year — Kesimpta is one of the more expensive MS therapies. Pharmacies and distributors are cautious about carrying inventory without confirmed insurance coverage, which can slow the fulfillment process.
Kesimpta has been gaining market share since its FDA approval in 2020, as more neurologists prescribe it for its combination of high efficacy and at-home convenience. Increased demand for any specialty biologic can create periodic tightness in the supply chain, even when no formal shortage exists.

While there is no official Kesimpta shortage in 2026, the challenges of accessing this specialty biologic are very real for many MS patients. The combination of specialty pharmacy distribution, insurance hurdles, and high costs can create delays that feel like a shortage — even when supply is technically adequate.
The most important thing you can do is stay proactive: start the prior authorization process early, use tools like Medfinder to track availability, and take advantage of financial assistance programs. If delays become dangerous for your health, talk to your neurologist immediately about alternative treatment options to avoid gaps in your MS care.
