Your Pharmacy Is Out of Insulin Aspart — Now What?

You need your mealtime insulin. Your pharmacy doesn't have it. And every hour that passes without a plan feels more stressful than the last.

If you're having trouble finding Insulin Aspart — whether it's NovoLog, Fiasp, or a biosimilar version — you're dealing with a problem that thousands of patients across the country are facing right now. With Novo Nordisk discontinuing several NovoLog product forms at the end of 2025 and biosimilar supply still ramping up, finding Insulin Aspart in stock takes a bit more effort than it used to.

The good news? There are real, practical strategies that work. Here are the best ways to track down your medication.

Tip #1: Use Medfinder to Search Real-Time Pharmacy Stock

This is the fastest way to find Insulin Aspart near you.

Medfinder is a free tool that shows you which pharmacies in your area currently have your medication in stock. Instead of calling pharmacy after pharmacy, you can search once and see your options.

Here's how to use it:

1. Go to medfinder.com
2. Search for "Insulin Aspart," "NovoLog," or "Fiasp"
3. Enter your zip code
4. See which pharmacies near you have it available

Medfinder is especially useful during shortages because it's updated regularly and covers independent pharmacies — not just the big chains.

Tip #2: Try Independent and Specialty Pharmacies

When a drug is in short supply, the big chain pharmacies (CVS, Walgreens, Rite Aid) are usually the first to run out. They serve the most patients, so their stock gets depleted quickly.

Independent pharmacies — the locally owned shops — often have stock when the chains don't. Here's why:

• They may use different wholesalers or distributors
• They serve fewer patients, so supply lasts longer
• They often have more flexibility to order from multiple sources

Don't overlook specialty pharmacies either. Some focus specifically on diabetes medications and may have better access to supply.

Pro tip: When you call, ask specifically about all available forms — vials, FlexTouch pens, and biosimilars (Kirsty, Merilog). You might find one form in stock even when another is unavailable.

Tip #3: Time Your Refills Strategically

Pharmacy stock levels fluctuate throughout the week. Deliveries from wholesalers typically arrive on specific days, and stock gets depleted as the week progresses.

Some strategies that help:

• Refill early in the week — most pharmacies receive shipments Monday through Wednesday
• Go during off-peak hours — early morning or mid-afternoon means shorter waits and more time for the pharmacist to help you
• Don't wait until you're out — start looking for your refill when you have 7-10 days of supply left
• Ask your pharmacy to set aside your supply — many pharmacies will reserve your insulin when a shipment arrives if you ask

What If You Still Can't Find Insulin Aspart?

If none of the above works, you have more options:

Ask About Biosimilars

Kirsty (insulin aspart-xjhz) is an interchangeable biosimilar to NovoLog. That means your pharmacist can substitute it for NovoLog without calling your doctor for a new prescription. Merilog (insulin aspart-szjj) is another biosimilar option, though your doctor may need to write a new prescription for it.

Consider Alternative Rapid-Acting Insulins

If Insulin Aspart isn't available in any form, talk to your doctor about switching to another rapid-acting insulin. Insulin Lispro (Humalog, Admelog, Lyumjev) and Insulin Glulisine (Apidra) work in a similar way and may be easier to find. Read our full breakdown of alternatives to Insulin Aspart.

Contact Novo Nordisk Directly

Novo Nordisk's NovoCare program (1-888-668-6444 or novocare.com) can help you locate supply, access savings cards, and connect with patient assistance programs if cost is a barrier.

Check With Your Insurance Company

Your insurance plan may have a shortage exception process that allows you to fill your prescription at a different pharmacy or switch to an alternative medication without prior authorization delays. Call the number on the back of your insurance card and explain the situation.

How to Avoid Getting Caught Off Guard Again

Shortages can come and go. Here are a few habits that help you stay ahead:

• Keep a buffer — always try to have at least a one-week emergency supply
• Sign up for refill reminders — your pharmacy or insurance plan likely offers automatic alerts
• Bookmark Medfinder — check availability before heading to the pharmacy
• Build a relationship with your pharmacist — they can alert you when stock arrives and set it aside

Final Thoughts

Finding Insulin Aspart during a shortage takes more effort, but it's not impossible. The key is to be proactive: use tools like Medfinder, explore independent pharmacies, ask about biosimilars, and stay in touch with your healthcare team.

Nobody should have to go without their insulin. If you're struggling, don't wait — start searching now and reach out for help.
