Epinephrine Single-Dose Auto-Injector

The uses and pharmacology described below reflect the FDA-approved labeling for this active ingredient; your veterinarian determines whether and how they apply to your animal's treatment plan.

Epinephrine is an adrenergic agonist that rapidly increases heart rate, constricts blood vessels, and relaxes airway muscles. On the FDA-approved human label, it is indicated for the emergency treatment of severe allergic reactions (anaphylaxis) and for use during cardiopulmonary resuscitation.

In veterinary medicine, epinephrine is used off-label as an emergency drug for anaphylaxis, cardiac arrest, and other acute crises in dogs, cats and horses. It is typically administered directly by a veterinary team in a clinical setting rather than given at home. This information is not a substitute for veterinary diagnosis, prescribing, or monitoring.

This is an emergency-use injectable intended for administration by a veterinary professional; it is not a medication given routinely at home. Effects can include a rapid heart rate, elevated blood pressure, tremors, and anxiety-like behavior, which are expected as part of its emergency action. Protect from light and check the expiration date before use, since epinephrine loses potency over time and a discolored or expired product should not be used. Store as directed on the label.
