Wondering why Trokendi XR is so hard to find at pharmacies? Learn the top reasons for limited availability and what you can do to get your prescription filled.
You've been prescribed Trokendi XR for seizures or migraines, and now your pharmacy is telling you they don't have it in stock. You're not imagining things — many patients across the country are running into the same problem in 2026.
Trokendi XR (Topiramate extended-release) is a once-daily capsule used to treat epilepsy and prevent migraines. It's made by Supernus Pharmaceuticals and has been on the market since 2013. While the medication itself hasn't been recalled or discontinued, finding it at your local pharmacy can be surprisingly difficult.
In this article, we'll explain exactly why Trokendi XR is hard to find, what's driving the problem, and what steps you can take to get your prescription filled.
Trokendi XR is the brand-name version of Topiramate in an extended-release capsule. It belongs to a class of medications called anticonvulsants. Doctors prescribe it for:
Unlike the immediate-release version of Topiramate (sold as Topamax), Trokendi XR is taken just once a day. The capsules must be swallowed whole — they cannot be opened, crushed, or sprinkled on food.
Trokendi XR comes in four strengths: 25 mg, 50 mg, 100 mg, and 200 mg.
There are several reasons patients are having trouble filling their Trokendi XR prescriptions in 2026. Here are the main factors:
Trokendi XR is expensive. The cash price for a one-month supply typically runs between $1,200 and $1,400 without insurance. Because of this high cost, many pharmacies — especially large chains — don't keep it on their shelves. Pharmacies prefer to stock medications that move quickly, and a high-cost, lower-demand brand-name drug like Trokendi XR often doesn't make the cut.
Many insurance plans require prior authorization before they'll cover Trokendi XR. Some plans also use step therapy, which means your doctor has to show that you tried cheaper alternatives like generic Topiramate (immediate-release) before the insurer will approve the brand-name extended-release version. These barriers mean fewer prescriptions are filled for Trokendi XR, which in turn means pharmacies stock less of it.
Generic Topiramate tablets are widely available and cost as little as $10 to $30 per month. While generic Topiramate is the immediate-release version (taken twice daily) rather than the extended-release formulation, many insurers push patients toward the cheaper generic. This has reduced the overall demand for brand-name Trokendi XR, leading pharmacies to carry smaller quantities or none at all.
As a brand-name specialty medication, Trokendi XR may be distributed through more limited channels than widely used generics. Not every pharmacy wholesaler carries it in large quantities, which can create regional gaps in availability. If your pharmacy's supplier doesn't stock it regularly, your pharmacist may need extra time to order it.
If your pharmacy tells you Trokendi XR is out of stock, don't panic. Here are some practical steps you can take:
Tools like Medfinder can help you search for pharmacies near you that have Trokendi XR in stock. Instead of calling pharmacy after pharmacy, you can check availability in just a few clicks.
Independent and specialty pharmacies are often more willing to order brand-name medications than large chain pharmacies. They may also have more flexibility in working with your insurance company on prior authorizations. Call a few local independent pharmacies and ask if they can order Trokendi XR for you.
If you consistently can't find Trokendi XR, talk to your doctor about whether an alternative might work for you. Options like Qudexy XR, generic Topiramate, or other anticonvulsants may be easier to find and more affordable.
Supernus Pharmaceuticals, the maker of Trokendi XR, offers a savings card for eligible commercially insured patients. They also have the Supernus Cares patient assistance program for uninsured or underinsured patients. These programs can help reduce your costs and may connect you with pharmacies that stock the medication.
If you know you'll need a refill, try to request it at least a week before you run out. This gives your pharmacy time to order the medication if they don't have it on hand. Planning ahead is one of the simplest ways to avoid gaps in your treatment.
Trokendi XR is a valuable medication for many people with epilepsy and migraines, but its high cost and limited demand have made it harder to find at many pharmacies. The good news is that with a little planning and the right tools, you can still get your prescription filled.
If you're struggling to find Trokendi XR, start by checking Medfinder to see which pharmacies near you have it in stock. And if cost is a concern, be sure to explore savings programs and discount options that can help bring the price down.
