How to Check If a Pharmacy Has Tresiba in Stock (Without Calling)

During the Tresiba shortage, finding out which pharmacy has insulin degludec in stock has become an exhausting process. Most patients resort to calling pharmacies one by one — often getting put on hold, transferred, or told to call back. It's frustrating, time-consuming, and stressful when you're running low on a medication you need every day.

There's a better way. Here are the most effective tools and strategies to check Tresiba availability — many of which don't require picking up the phone at all.

Method 1: medfinder — The Fastest Option

The quickest way to check Tresiba availability without calling is to use medfinder. Here's how it works:

Enter Tresiba (or insulin degludec) as your medication

Specify your dosage and concentration (U-100 or U-200)

Enter your zip code

medfinder calls pharmacies on your behalf to find which ones can fill your prescription

Results are texted to you — no hold music, no callbacks, no frustration

This is especially valuable if you're in a hurry, have multiple medications to check, or simply don't have time to make a dozen phone calls during pharmacy hours.

Method 2: Online Pharmacy Portals and Apps

Some major pharmacy chains allow you to check medication availability online or through their mobile apps before visiting in person:

CVS Pharmacy app/website: Allows you to check if a prescription is in stock at your local store before pickup

Walgreens app: Lets you check prescription status and sometimes shows whether an item is in stock at a specific location

Amazon Pharmacy: Shows availability and pricing upfront before you order. Often has better supply of specialty medications.

Note that online pharmacy tools are better at showing inventory for routine medications. During a shortage, real-time stock data can be inaccurate — availability may change faster than the website updates.

Method 3: GoodRx and Price Comparison Tools

GoodRx (goodrx.com) and SingleCare (singlecare.com) show which pharmacies near you have pricing data for Tresiba. If a pharmacy shows a GoodRx price, it generally means they stock the medication. While these tools don't provide real-time stock confirmation, they can help you identify which pharmacies are most likely to have Tresiba and compare prices at the same time.

Method 4: Transfer Your Prescription Strategically

If you already have Tresiba on file at a pharmacy that's out of stock, you can transfer the prescription to another pharmacy without needing your doctor to write a new one. Here's how:

Find a pharmacy that has Tresiba in stock (using any of the methods above)

Contact the new pharmacy with your name, date of birth, and current pharmacy's name and phone number

The new pharmacy contacts your current pharmacy to transfer the prescription — you don't need to do anything else

Tips for Checking Stock Effectively During a Shortage

Check early in the week: Many pharmacies receive shipments Monday through Wednesday. Stock may be depleted by Thursday or Friday.

Check both concentrations: Search for both Tresiba U-100 and U-200 — one concentration may be available even if the other is not.

Widen your search radius: Try pharmacies 15-20 miles out, not just your immediate neighborhood. Demand patterns vary across regions.

Don't overlook independent pharmacies: Chain pharmacies share distributors. Independents often use different suppliers and may have stock when chains are all out.
