Invokamet Shortage Update: What Patients Need to Know in 2026

Is Invokamet in Shortage in 2026?

If you've had trouble finding Invokamet at your pharmacy recently, you're probably wondering: is there a shortage? The short answer is that Invokamet is not currently on the FDA's official drug shortage list as of early 2026. But that doesn't mean it's easy to find.

Many patients report difficulty locating Invokamet at their regular pharmacy, and there are real reasons why. This article breaks down the current availability situation, what's driving the problem, what Invokamet costs in 2026, and what you can do to make sure you don't miss a dose.

The Current Availability Picture

Invokamet (Canagliflozin/Metformin) is manufactured by Janssen Pharmaceuticals, a Johnson & Johnson company. As of March 2026, the medication remains in active production and is not in a formal shortage.

However, availability varies significantly from pharmacy to pharmacy. Here's why:

• Brand-only product: There is no generic version of Invokamet, and generics aren't expected until around 2029. With only one manufacturer, supply depends entirely on Janssen's production and distribution.
• Pharmacy stocking decisions: At $575 to $800 per month retail, Invokamet is expensive for pharmacies to keep on hand. Many locations only order it when a specific patient needs it.
• Multiple strengths: Invokamet comes in four strengths (50/500, 50/1000, 150/500, 150/1000 mg) in both immediate-release and XR formulations. A pharmacy might carry one strength but not yours.

So while there's no official shortage, the practical experience for patients can feel like one. For tips on locating it, see our guide on how to find Invokamet in stock near you.

Why Is Invokamet Hard to Find?

Several factors contribute to the difficulty patients face:

No Generic Competition

When a medication has generic versions available, multiple manufacturers produce it, creating abundant supply. Invokamet's patent protection (expected through 2029) means Janssen is the sole producer. This limits overall supply compared to widely available generics like Metformin.

Insurance Barriers

Many health insurance plans require prior authorization or step therapy before covering Invokamet. Some plans prefer alternative SGLT2/Metformin combinations like Synjardy or Xigduo XR. When fewer patients are approved for Invokamet through insurance, pharmacies have less incentive to stock it.

Metformin's History of Shortages

While Invokamet itself hasn't experienced major shortages, Metformin — one of its two active ingredients — faced significant supply disruptions in 2020 due to NDMA (a potential carcinogen) contamination recalls. Those recalls affected several generic Metformin manufacturers. Although that issue has been resolved, it's a reminder that supply chain problems can impact diabetes medications at any time.

Pharmacy Consolidation

As more independent pharmacies close and chain pharmacies consolidate, inventory decisions are increasingly made at the corporate level. Corporate pharmacy chains tend to stock high-volume, high-turnover medications and may deprioritize niche brand-name products like Invokamet.

What Does Invokamet Cost in 2026?

Here's what you can expect to pay for a 30-day supply (60 tablets) of Invokamet in 2026:

• Retail cash price: $575 to $800 depending on strength and pharmacy
• With GoodRx coupon: As low as $576 at select pharmacies
• With SingleCare coupon: Around $587 for 60 tablets
• With Janssen CarePath Savings Card: $0 per month for eligible commercially insured patients
• With Medicare Part D: Varies by plan; some patients pay $100 to $200+ per month in copays

New Options and Developments

While waiting for a generic Invokamet, here are some developments that may help patients:

• Expanded SGLT2 inhibitor indications: SGLT2 inhibitors like Canagliflozin are increasingly recognized for cardiovascular and kidney benefits beyond blood sugar control. This growing evidence base may improve insurance coverage for Invokamet and its alternatives.
• Manufacturer savings programs: Janssen continues to offer the CarePath Savings Program, which can reduce your monthly cost to $0 with commercial insurance.
• Telehealth prescribing: Many telehealth providers now prescribe diabetes medications including Invokamet, making it easier to get a prescription without an in-person visit. Learn more about finding a doctor who can prescribe Invokamet.

How to Find Invokamet in Stock Right Now

Here are your best strategies:

1. Use Medfinder to check pharmacy availability in your area instantly.

4. Refill early — request refills 5 to 7 days before you run out to give your pharmacy time to order.
5. Talk to your doctor about alternatives if you consistently can't find Invokamet. Options include Synjardy, Xigduo XR, or taking Invokana and Metformin separately.

Invokamet isn't in an official shortage in 2026, but real-world availability challenges can make it feel that way. The combination of being a brand-only product, insurance restrictions, and pharmacy stocking decisions means you may need to be proactive about filling your prescription.
