EpiPen delivers epinephrine (adrenaline), which rapidly counteracts the effects of a severe allergic reaction.

• Relaxes airway muscles to improve breathing
• Constricts blood vessels to raise blood pressure
• Reduces swelling, redness, and hives
• Helps stabilise the body during anaphylaxis

Symptoms may improve quickly, but delayed or rebound reactions can occur. Medical observation after use is essential.
