Struggling to find Toujeo at your pharmacy? Learn why this long-acting insulin is hard to find in 2026 and what you can do to get your prescription filled.
You show up at the pharmacy, hand over your prescription for Toujeo, and hear the words no one with diabetes wants to hear: "We don't have it in stock right now."
It's frustrating, stressful, and — when you depend on insulin to manage your blood sugar — potentially dangerous. If you've been struggling to find Toujeo at your local pharmacy in 2026, you're far from the only one dealing with this problem.
In this article, we'll explain exactly what Toujeo is, why it's been difficult to find, and — most importantly — what steps you can take to get your hands on it.
Toujeo is a brand-name, long-acting basal insulin made by Sanofi. Its active ingredient is Insulin Glargine, concentrated at 300 units per milliliter (U-300). That's three times more concentrated than Lantus, which contains Insulin Glargine at 100 units/mL.
Toujeo is FDA-approved for adults with type 1 diabetes and type 2 diabetes. It works by providing a slow, steady release of insulin over roughly 24 to 36 hours, helping keep blood sugar levels stable throughout the day and night.
It comes in two pen formats:

There's no single reason Toujeo has been tough to track down. Instead, it's a combination of factors hitting at the same time:
In January 2025, Mylan/Biocon phased out Semglee, a biosimilar of Insulin Glargine U-100 that many patients and insurers relied on as a lower-cost alternative. When Semglee disappeared, patients and prescribers turned to other Insulin Glargine products — including Toujeo. This sudden increase in demand put pressure on supply chains that were already operating with thin margins.
Many insurance plans responded to the Semglee shortage by adding Toujeo to their preferred formulary lists, sometimes without prior authorization. While this was good news for coverage, it also meant more prescriptions flowing to pharmacies that weren't stocked for the increased volume.
Most retail pharmacies — especially large chains — use automated inventory systems that order based on historical demand. When demand for Toujeo spiked, these systems were slow to catch up. Independent pharmacies, which often have more flexibility in ordering, may be better positioned to stock it.
The insulin market in the United States has faced ongoing supply chain disruptions. Manufacturing insulin is a complex biological process, and any hiccup — from raw material sourcing to cold-chain distribution — can ripple through the system. The ASHP (American Society of Health-System Pharmacists) has tracked Insulin Glargine supply issues through early 2026.
The good news is that Toujeo is not formally discontinued, and there are several practical steps you can take:
Medfinder lets you search for Toujeo and see which pharmacies near you actually have it in stock. Instead of calling pharmacy after pharmacy, you can check availability from your phone or computer in seconds.
Independent and compounding pharmacies often have more direct relationships with wholesalers and can sometimes source medications that chain pharmacies can't. Don't overlook smaller pharmacies in your area.
If Toujeo is genuinely unavailable in your area, there are other long-acting insulins your doctor might consider. These include Lantus (Insulin Glargine U-100), Tresiba (Insulin Degludec), or Levemir (Insulin Detemir). Read more in our article on alternatives to Toujeo.
Cost can be a barrier even when supply is available. Sanofi's Insulins Valyou Savings Program offers Toujeo for just $35 per 30-day supply for uninsured patients or insured patients paying cash. Learn more about saving money in our Toujeo savings guide.
If you're currently stable on Toujeo, try to refill your prescription a few days early whenever your insurance allows. Running out of basal insulin is a medical emergency, so building in a small buffer can reduce stress significantly.
Finding Toujeo in 2026 can be a challenge, but it's not impossible. The key is to be proactive: use tools like Medfinder to search for availability, explore independent pharmacies, and talk to your prescriber about backup plans.
