Is Xofluza 40 Mg Dose Pack in shortage in 2026? Get the latest update on availability, pricing, and what you can do if your pharmacy is out of stock.
If you've been prescribed Xofluza 40 Mg Dose Pack (Baloxavir Marboxil) and can't find it at your pharmacy, you're probably wondering: is Xofluza in shortage? What's going on with supply? And what should you do?
Here's everything you need to know about Xofluza availability in 2026.
As of early 2026, Xofluza is not formally listed on the FDA drug shortage database. However, that doesn't mean it's easy to find. Many patients across the country report difficulty locating Xofluza at their local pharmacies, especially during the peak flu months of January and February.
The reality is that Xofluza experiences seasonal availability issues rather than a traditional manufacturing shortage. The drug is being produced — it's just not always sitting on pharmacy shelves when you need it.
Several factors contribute to the ongoing difficulty in finding Xofluza. For a detailed breakdown, see our full article: Why Is Xofluza So Hard to Find?
Xofluza is only prescribed during flu season, which typically runs from October through March. Pharmacies can't predict exactly how severe each flu season will be, so stocking decisions are often conservative. When flu cases surge, demand overwhelms available supply.
Each patient uses one entire dose pack. Unlike chronic medications where one bottle serves a patient for a month, Xofluza inventory gets depleted one patient at a time. A pharmacy might have 10 dose packs and go through them in a single busy day.
Xofluza has no generic version as of 2026. With only one manufacturer (Genentech), there's a single supply pipeline. If there are any production or distribution delays, there's no backup source.
Many pharmacies — especially independents — choose not to stock Xofluza routinely. At $150 to $200 per dose pack, it's expensive inventory that may expire before being sold if flu season is mild. This creates a frustrating cycle: patients can't find it because pharmacies don't stock it, and pharmacies don't stock it because demand is unpredictable.
The cash price (without insurance) for Xofluza 40 Mg Dose Pack typically ranges from $150 to $200, depending on the pharmacy.
If you have commercial insurance, you may pay significantly less. Genentech offers a savings card that can reduce your copay to as little as $30. For patients without insurance, Genentech's Patient Foundation may provide the medication at no cost. For more details, read: How to Save Money on Xofluza.
As of early 2026, Xofluza remains the only cap-dependent endonuclease inhibitor available in the United States. No new drugs in this class have been approved, and no generic version of Baloxavir Marboxil has come to market.
However, the landscape of flu antivirals continues to include several effective alternatives:

If you've been prescribed Xofluza and need to find it quickly, here are the best steps:
Medfinder helps you find hard-to-locate medications by showing real-time pharmacy availability near your zip code. It's the fastest way to check multiple pharmacies at once.
Big chain pharmacies run out first. Independent and hospital pharmacies may still have stock. For detailed tips, read: How to Find Xofluza in Stock Near You.
Some prescribers have access to pharmacy networks and can check stock levels before sending your prescription. Ask them to send it to a pharmacy that has it.
If time is running out (remember the 48-hour window), your doctor can switch you to generic Tamiflu (Oseltamivir), which is much easier to find and very affordable.
The 2024-2025 flu season was particularly severe, and Xofluza availability was significantly impacted. Many regions experienced spot shortages as flu cases surged in November and December 2024. Similar patterns occurred during the 2022-2023 flu season.
These seasonal shortages have become somewhat predictable: availability tightens every year during the peak flu months. If you get a flu diagnosis during January or February, you may need to act quickly to secure your Xofluza prescription.
Baloxavir Marboxil is still under patent protection. While generic versions will eventually come to market, no generic applications have been approved or are expected in the near term. For now, the brand-name Xofluza from Genentech is the only option.
Xofluza 40 Mg Dose Pack isn't in a formal FDA shortage, but it remains difficult to find during flu season due to its seasonal demand, single-dose format, and lack of a generic version. If your pharmacy is out of stock, use Medfinder to search nearby pharmacies, try independent locations, and don't wait too long — if you can't find it, ask your doctor about switching to Tamiflu.
The flu doesn't wait, and neither should you.
