When You Can't Get Afrezza, You Still Have Options

If you've been using Afrezza — or your doctor has just prescribed it — and you're having trouble getting it filled, you're probably wondering: what are my alternatives? Maybe your pharmacy doesn't carry it, your insurance won't cover it without a lengthy prior authorization, or the cost is just too high right now.

Whatever the reason, you shouldn't have to go without mealtime insulin. In this article, we'll explain how Afrezza works, why it's unique, and walk through the best alternatives that your doctor can prescribe if Afrezza isn't available to you right now.

Important: Never switch or stop your insulin without talking to your doctor first. The alternatives listed here all require a prescription and a conversation with your healthcare provider about dosing.

What Is Afrezza and How Does It Work?

Afrezza is the only FDA-approved inhaled insulin for adults with type 1 or type 2 diabetes. Made by MannKind Corporation, it delivers rapid-acting human insulin through a small handheld inhaler using a technology called Technosphere.

What makes Afrezza different from injectable insulins is speed. It starts working in about 12 minutes — faster than any injectable rapid-acting insulin — and peaks at around 35 to 55 minutes. This ultra-rapid onset closely mimics your body's natural first-phase insulin response when you eat, which can mean:

• Better post-meal blood sugar control
• Less risk of late-onset hypoglycemia (low blood sugar hours after eating)
• No needles at mealtimes

Afrezza comes in 4-unit, 8-unit, and 12-unit single-use cartridges. You take it at the beginning of each meal by inhaling through the Afrezza Inhaler. For a deeper dive, read our article on how Afrezza works.

Why You Might Need an Alternative

There are several common reasons patients look for alternatives to Afrezza:

• Availability: Most pharmacies don't routinely stock Afrezza due to its small patient base. Learn more about why Afrezza is hard to find.
• Cost: Without insurance, Afrezza costs $470 to $2,320 per month. Even with the savings card ($35/fill), it may be more expensive than generic injectable alternatives.
• Insurance barriers: Many plans require prior authorization or step therapy before covering Afrezza.
• Medical contraindications: Afrezza is contraindicated for patients with asthma, COPD, or other chronic lung diseases due to the risk of acute bronchospasm. It's also not recommended for smokers.

Alternative 1: Humalog (Insulin Lispro)

Humalog is one of the most widely prescribed rapid-acting injectable insulins. It's been on the market since 1996 and is made by Eli Lilly.

• How it works: Insulin lispro is an analog insulin that starts working in about 15-30 minutes, peaks at 30-90 minutes, and lasts 3-5 hours.
• How to take it: Injected subcutaneously (under the skin) before meals using a pen, syringe, or insulin pump.
• Generic available: Yes. Authorized generic insulin lispro is available for significantly less — often $25 to $50 per vial with coupons.
• Insurance coverage: Widely covered by most insurance plans, often on preferred formulary tiers.
• Key difference from Afrezza: Slightly slower onset (15-30 minutes vs. 12 minutes) and requires an injection. However, it's much more widely available and less expensive.

Alternative 2: NovoLog (Insulin Aspart)

NovoLog is another popular rapid-acting injectable insulin, made by Novo Nordisk.

• How it works: Insulin aspart starts working in about 10-20 minutes, peaks at 40-50 minutes, and lasts 3-5 hours.
• How to take it: Injected via pen (FlexPen), syringe, or insulin pump before meals.
• Generic/biosimilar available: Yes. Biosimilar versions like Insulin Aspart (authorized generic) are available at lower cost.
• Insurance coverage: Widely covered. One of the most commonly prescribed mealtime insulins in the U.S.
• Key difference from Afrezza: Similar speed of onset to Humalog. Requires injection but is much easier to find at any pharmacy and is available in generic form.

Alternative 3: Apidra (Insulin Glulisine)

Apidra is a rapid-acting insulin made by Sanofi, less commonly prescribed than Humalog or NovoLog but still widely available.

• How it works: Insulin glulisine starts working in about 15-30 minutes, peaks at approximately 60 minutes, and lasts 3-4 hours.
• How to take it: Injected subcutaneously via pen or syringe before meals.
• Generic available: Not currently, but it is generally less expensive than brand-name Humalog or NovoLog.
• Insurance coverage: Covered by most plans, though it may be non-preferred on some formularies.
• Key difference from Afrezza: Injectable with a similar time profile to other rapid-acting insulins. Less commonly prescribed but a solid option if Humalog or NovoLog aren't available.

Alternative 4: Lyumjev (Insulin Lispro-aabc)

Lyumjev is the closest injectable alternative to Afrezza in terms of speed. Made by Eli Lilly, it's an ultra-rapid-acting insulin that works faster than traditional rapid-acting insulins.

• How it works: Lyumjev contains insulin lispro with added excipients (treprostinil and citrate) that speed up absorption. It starts working in about 5-10 minutes at the injection site, with a faster onset than standard rapid-acting insulins.
• How to take it: Injected subcutaneously or used in an insulin pump.
• Generic available: No generic currently available.
• Insurance coverage: Covered by many commercial plans, but may require prior authorization. Check with your plan.
• Key difference from Afrezza: Lyumjev is the fastest injectable insulin available, making it the closest match to Afrezza's ultra-rapid profile. However, it still requires an injection and does not have the same lung-absorption mechanism.

Comparing the Alternatives at a Glance

Here's a quick comparison to help you and your doctor decide:

• Fastest non-injectable option: Afrezza (12-minute onset)
• Fastest injectable option: Lyumjev (5-10 minute onset)
• Most affordable: Generic Insulin Lispro (Humalog generic) — as low as $25-50 per vial
• Most widely available: Humalog and NovoLog — stocked at virtually every pharmacy
• Best for needle-free: Afrezza — the only inhaled insulin on the market

Final Thoughts

Afrezza offers unique benefits — ultra-fast action, no injections, and a profile that closely mimics natural insulin. But if you can't access it right now, you have strong alternatives. Humalog and NovoLog are available at nearly every pharmacy with affordable generic options. Lyumjev offers the closest speed profile for patients who value rapid onset.

Talk to your doctor about which alternative makes sense for your situation. And don't give up on Afrezza if it's the right fit for you — check Medfinder to find pharmacies that have it in stock, explore the savings programs available, or learn more about how to find Afrezza near you.
