Overview
Epinephrine, commonly known by brand names such as Adrenalin and EpiPen, is a critical medication used in veterinary medicine for emergency situations. It is a sympathomimetic drug primarily used to treat severe allergic reactions and cardiac arrest in pets.
How It Works
Epinephrine works by stimulating alpha and beta-adrenergic receptors in the body, which leads to vasoconstriction, increased heart rate, and bronchodilation. This helps to quickly counteract life-threatening symptoms during anaphylactic reactions and cardiac events.

- Severe allergic reactions (anaphylaxis)
- Cardiac arrest
- Asthma attacks (in some cases)
