Epinephrine is commonly known as adrenaline. Your body naturally produces it during times of stress, but it can also be used in medical situations to treat various conditions. Read this lesson to learn about its uses and potential side effects.

What Is Epinephrine?

Have you ever read a news story about a man who miraculously lifted a car off of another person? How was he able to do this? In the heat of the moment, his body produced a burst of epinephrine, allowing him to do such a remarkable feat! Epinephrine is a hormone naturally produced in the medulla of the brain. It is secreted by the adrenal glands during times of stress, and you may have already heard of this fight-or-flight response, which prepares the body for strenuous activity. Intense fear or anger can trigger its release, giving the body a surge of energy.
