Homonym: Epi (Epidemic)
Epi, short for epinephrine, is a hormone and neurotransmitter produced by the adrenal glands. It plays a crucial role in the body's fight-or-flight response, increasing heart rate, blood flow, and energy availability during stressful situations. Epi is commonly used in medical emergencies, particularly for treating severe allergic reactions, known as anaphylaxis.
In medical settings, epinephrine is often administered through an auto-injector, such as an EpiPen. This device allows individuals with severe allergies to quickly deliver a dose of epinephrine when needed. The rapid action of Epi helps to reverse symptoms like swelling, difficulty breathing, and low blood pressure, making it a vital tool for those at risk.
