Basaglar Shortage Update: What Patients Need to Know in 2026

The insulin glargine market has experienced significant disruption in late 2025 and into 2026. If you're a Basaglar patient, you may have noticed more difficulty filling your prescription or heard about pharmacy stock issues from your provider. This update covers everything you need to know about Basaglar's availability status in 2026.

Current Status: Is Basaglar in Shortage in 2026?

As of early 2026, Basaglar KwikPens are NOT listed on the FDA drug shortage database. Eli Lilly has confirmed that Basaglar KwikPens remain in production and available. The American Society of Health-System Pharmacists (ASHP) updated its insulin glargine shortage bulletin on March 25, 2026 to confirm that Lilly has Basaglar KwikPens available nationally.

However, this national availability does not automatically mean your local pharmacy has Basaglar in stock. Localized shortages — where specific pharmacies run out due to increased demand, ordering delays, or distribution issues — are occurring and causing real problems for patients.

The Semglee Discontinuation: Why It Matters for Basaglar Patients

The biggest disruption driving 2026 insulin glargine availability issues is the discontinuation of Semglee (insulin glargine-yfgn) by Biocon on December 31, 2025. Semglee was the most widely used interchangeable biosimilar for Lantus, prescribed to millions of patients. When Semglee disappeared from the market, those patients needed to transition to alternative products.

In the months following:

• Demand surged for Basaglar, Lantus, and Rezvoglar simultaneously.
• Insurance formularies scrambled to update Semglee coverage to alternative products.
• Some pharmacies that hadn't stocked large quantities of Basaglar suddenly faced high demand they couldn't immediately fill.

The result: pockets of unavailability across the country, even though Basaglar's supply chain is intact. This is a demand-side problem, not a manufacturing or supply-side problem.

The Basaglar Tempo Pen Is Being Discontinued

Separately from the glargine market disruption, Eli Lilly has announced a business decision to discontinue the Basaglar Tempo Pen. Here is the timeline:

• July 27, 2026: Last date Basaglar Tempo Pens will be available at pharmacies.
• July 28, 2026: The Tempo Platform will stop recording diabetes-related data.
• December 31, 2026: The TempoSmart App and Tempo Insights portal will be fully discontinued.

If you use Tempo Pens and have remaining supply after July 27, you can continue using them until their expiration date. However, data tracking functionality will not work. The Basaglar KwikPen continues without interruption.

What You Should Do Right Now

Here are the most important action steps for Basaglar patients in 2026:

1. If you use a Tempo Pen: Contact your provider now to switch your prescription to the Basaglar KwikPen. Don't wait until after July 2026.
2. Refill early: Given increased demand, don't wait until you're almost out. Most plans allow refills 7–10 days before your current supply runs out.
3. Use medfinder: If your pharmacy is out, medfinder calls pharmacies near you to check which ones can fill your Basaglar prescription.
4. Ask about mail order: Mail-order pharmacies often carry better inventory for maintenance medications like basal insulin and can fill 90-day supplies.
5. Know your savings options: Eli Lilly's cash savings card caps Basaglar at $35/month (no insurance required, valid through December 31, 2026). If cost is a barrier, this card may help.

What the Basaglar Market Looks Like Going Forward

The insulin glargine market is expected to stabilize as formularies adjust post-Semglee and distribution channels adapt to new demand patterns. Eli Lilly continues to manufacture Basaglar KwikPens, and the overall supply of U-100 insulin glargine products from multiple manufacturers (Lilly, Sanofi, Winthrop) remains intact.

For patients: the best protection is building a small safety buffer, refilling early, and knowing how to quickly locate a pharmacy with stock when your usual one runs out.
