Epinephrine (adrenaline) is both a hormone and a neurotransmitter.[1] Epinephrine is a vasoconstrictor and cardiac stimulatant, and is automatically produced in reaction to shock or fear.[1][2]

Epinephrine is the active ingredient in 'EpiPens, which are used to treat anaphylaxis (severe allergic reactions) that may occur in people with allergies, mast cell activation syndrome (MCAS) or mast cell activation disorder (MCAD).[2] Epinephrine is also used to treat anaphylaxis caused by exercise or low blood pressure caused by septic shock.[3]
