No potency threshold (e.g., 90%) or regulatory standard for expiration meaning is stated in the provided label excerpts.
Effectiveness of an expired EpiPen is not guaranteed.
The provided label excerpts do not make a statement about clinical effectiveness/guarantee of expired devices.
Expired epinephrine may degrade / degradation reduces its ability to reverse anaphylaxis.
The provided excerpts discuss deterioration related to light/air exposure and replacing if discolored, but do not state that expiration-related degradation reduces ability to reverse anaphylaxis.
Studies show 90% potency retention up to a year past expiry under ideal storage.
No study results, potency retention percentages, or time-past-expiry data are provided in the label excerpts.
EpiPens expire.
The concept of an expiration date is not explicitly stated in the provided label excerpts.
Each EpiPen auto-injector has a printed expiration date.
A printed expiration date is not explicitly stated in the provided label excerpts.

Some users report using expired EpiPens in emergencies.
No patient-use or survey/reporting statements are present in the provided label excerpts.
Expired epinephrine may degrade.
While deterioration is described with exposure to air/light, the claim specifically about expiration-age degradation is not stated in the provided excerpts.
Manufacturers set conservative expiration dates for safety.
No rationale for setting expiration dates is provided in the provided excerpts.
The FDA advises against use of expired EpiPens.

No such storage-location guidance is included in the provided label excerpts.
Proper storage can help reach the full labeled shelf life.
No statement about achieving labeled shelf life via proper storage is included in the provided excerpts.

Safety Assessment
Potential Patient Risk:
High
Several claims directly address whether expired EpiPens will be potent/effective or how expiration affects anaphylaxis reversal, but these claims are not supported by the provided FDA label excerpts. Overreaching on expired-device effectiveness could lead to inappropriate reliance.

Recommendation

Primary Issue
Multiple safety-relevant expiration/potency/effectiveness and regulatory/policy claims are unsupported by the supplied label excerpts.
Suggested Improvement
Remove or rephrase all unsupported claims about potency thresholds (e.g., 90%), clinical effectiveness of expired devices, study results, and FDA advisory/patent/shortage/cost/generic/alternative-device statements. Keep only label-supported storage/light-sensitivity and disposal guidance and the label-supported instruction to replace the device if the solution is discolored/cloudy/contains particles.
