Check your Omnipod Pod lot: FDA correction and DKA steps

If you use an insulin pod system, an FDA-published voluntary medical device correction is a good reason to double-check your Pod lot number. On May 26, 2026, FDA posted an update that specific lots of certain Omnipod Pods may under-deliver insulin due to a manufacturing issue.

Because insulin under-delivery can raise blood sugar—and, in severe cases, lead to diabetic ketoacidosis (DKA)—this article focuses on the practical steps FDA and diabetes organizations recommend: confirm whether your lot is included, monitor for warning signs, and seek urgent care when needed.

What FDA says about the Omnipod Pod correction (May 26, 2026)

FDA’s notice states that Insulet issued a voluntary correction for specific lots of Omnipod 5, Omnipod DASH, and the Omnipod Insulin Management System (Omnipod Eros) Pods due to a manufacturing issue that could result in insulin under-delivery.

Insulet identified that some Pods from specific lots may have a small tear in the tubing (cannula) just above the skin, between the Pod and the point where the cannula enters the body. If this happens, insulin may leak outside the Pod instead of being fully delivered into the body.

FDA also notes that individuals using an affected Pod may notice wetness on the skin or Pod adhesive or detect the smell of insulin, but in some cases the issue may be difficult to detect. In the most severe cases, prolonged high blood glucose can lead to DKA.

FDA further states the issue does not affect continuous glucose monitoring (CGM) systems or CGM readings.

Who should act—and what to do next

The FDA instructions focus on Pod lots, not an entire product line. Your next reasonable steps are:

Check your Pod lot number using the “Check Pod Lot” process listed in FDA’s posted notice (via Insulet’s lot-check page).
If your lot is included: discontinue use of that Pod and replace it with a Pod from an unaffected lot.
Request replacement Pods at no cost, if instructed for your affected lot.
If you have questions or need help, follow the support contact information FDA provides in the posted announcement.

If you’re a caregiver, it’s especially helpful to know where the lot number is displayed and to ensure the person with diabetes is following the lot-check and replacement steps.

Because this may be hard to detect: monitor blood sugar and ketones

Under-delivery can lead to high blood glucose. If insulin isn’t delivered properly, this can progress—sometimes quickly—toward DKA, a medical emergency.

DKA warning signs (seek emergency care)

The CDC describes DKA as serious and can be life-threatening. Warning signs can include:

Very thirsty, urinating more than usual
Fast, deep breathing
Dry mouth or skin, flushed face
Fruity-smelling breath
Headache, feeling very tired
Nausea/vomiting, stomach pain

CDC advises go to the emergency room or call 911 right away if you have signs such as:

Blood sugar stays at 300 mg/dL or above
Fruity breath
Vomiting and can’t keep food or drinks down
Trouble breathing
Multiple signs and symptoms of DKA

When to check ketones

CDC guidance says that if you have diabetes and are sick or your blood sugar is 250 mg/dL or above, you should:

Check blood sugar every 4 to 6 hours
Check urine for ketones

CDC also advises testing for ketones if you have symptoms of DKA, and notes that elevated ketones are an emergency warning.

The American Diabetes Association (ADA) adds that people should check ketones if they feel unwell (especially with nausea, vomiting, or fatigue) or if blood glucose is ≥250 mg/dL for ≥2 hours—while also emphasizing an individualized ketone management plan developed with their diabetes care team.

ADA also notes that when ketones are elevated, people should continue taking insulin as directed (and not stop insulin unless their clinician tells them to) and recheck ketones as recommended in their plan.

What research can (and can’t) tell us about DKA in pump users

A PubMed-indexed prospective observational study of adults admitted with DKA compared people using insulin pumps versus multiple daily injections. In that study, the most common precipitating factor overall was insulin non-adherence, and pump users more often had pump/tubing-related causes. Observational findings help describe patterns, but they cannot confirm the cause of DKA in any individual person—or validate what caused a specific case.

For this Omnipod correction, the most important “source of truth” for affected users is FDA’s posted instructions: check your lot, replace affected Pods, and monitor for high glucose and ketones.

Practical checklist for affected users and caregivers

Confirm your lot: Is it included in the FDA-described correction?
Have a ketone plan ready: Know what to test (urine and/or blood) and when to call your care team.
Act quickly if glucose rises: Follow the CDC ketone-monitoring steps if you’re sick or glucose is high.
Know the emergency triggers: If symptoms suggest DKA or glucose stays high (e.g., ≥300 mg/dL), treat it as an emergency.

Bottom line

FDA’s May 26, 2026 notice is focused on specific Omnipod Pod lots that could under-deliver insulin. The safest next step is to check your Pod lot and follow the replacement instructions. If high blood sugar and/or ketones suggest possible DKA, use the CDC emergency guidance (including call 911 or go to the ER for the listed warning signs).
