Having trouble finding Janumet at your pharmacy? Learn why this diabetes medication can be hard to find in 2026 and what you can do to get your prescription filled.
You go to the pharmacy expecting to pick up your Janumet prescription — and they tell you it's out of stock. Maybe they say it'll be a few days. Maybe they're not sure when it's coming back. If this sounds familiar, you're not the only one dealing with it.
Janumet is one of the most commonly prescribed medications for type 2 diabetes, and many patients have reported difficulty filling their prescriptions in recent months. In this article, we'll explain what Janumet is, why it can be hard to find, and what steps you can take to get your medication.
Janumet is a brand-name prescription medication made by Merck. It combines two active ingredients — Sitagliptin (a DPP-4 inhibitor) and Metformin (a biguanide) — into a single tablet. Together, these two drugs help control blood sugar in adults with type 2 diabetes.
Sitagliptin works by increasing the levels of natural hormones called incretins, which help your body produce more insulin after meals and reduce the amount of sugar your liver makes. Metformin lowers the amount of glucose your liver releases and helps your body respond better to insulin.
Janumet comes in two forms:

There are several reasons why you might have trouble finding Janumet at your local pharmacy in 2026:
The pharmaceutical supply chain has faced ongoing challenges since the COVID-19 pandemic. Manufacturing delays, raw material shortages, and distribution bottlenecks can all lead to temporary stock-outs at individual pharmacies. Even though Janumet isn't on the FDA's official drug shortage list, these disruptions can make it harder to find at certain locations.
The number of Americans living with type 2 diabetes continues to grow, with over 37 million people affected. At the same time, the surge in demand for GLP-1 agonists like Ozempic and Mounjaro has put pressure on the entire diabetes drug supply chain. Pharmacies that carry multiple diabetes medications may prioritize stocking higher-demand drugs, leaving less shelf space for combination products like Janumet.
As of early 2026, there is no generic version of Janumet on the market. The key patent on Sitagliptin doesn't expire until November 24, 2026, which means only Merck produces this medication. With just one manufacturer, any production hiccup can affect availability nationwide. A generic version may become available in late 2026 or 2027, which should help with supply.
Some pharmacies may not keep Janumet in stock because it's a higher-cost brand-name medication. If your pharmacy doesn't regularly fill Janumet prescriptions, they may not order it until a patient specifically requests it — which can cause a delay of several days.
If your usual pharmacy doesn't have Janumet, here are some practical steps you can take:
Visit Medfinder to search for pharmacies near you that currently have Janumet in stock. It's a free tool that saves you the hassle of calling pharmacy after pharmacy.
Big chain pharmacies aren't your only option. Independent pharmacies often have more flexible ordering and may be able to get Janumet faster. Specialty pharmacies that focus on chronic conditions like diabetes may also be more likely to carry it.
If your pharmacy is out of stock, ask the pharmacist to place a special order. In many cases, the medication can arrive within one to three business days from their distributor.
If you can't find Janumet and you're running low, talk to your prescriber. They may be able to switch you to a similar medication like Jentadueto, Kombiglyze XR, or Kazano, or prescribe Sitagliptin (Januvia) and Metformin as separate tablets.
The cash price of Janumet can be $600 to $750 for a 30-day supply. If cost is making it harder to fill your prescription, explore our guide on how to save money on Janumet for information about coupons and patient assistance programs.
Finding Janumet shouldn't feel like a scavenger hunt, but the reality of supply chains, patent protections, and pharmacy stocking practices means it sometimes does. The good news is that there are steps you can take to find your medication — and tools like Medfinder that make it easier.
If you're having ongoing trouble filling your prescription, don't wait until you're completely out. Start looking early, talk to your pharmacist and doctor, and keep an eye on the upcoming generic options that could make Janumet more widely available later in 2026.
