Epinephrine auto-injectors are prescribed medication delivery systems approved by the Food and Drug Administration (FDA) to treat life-threatening allergic reactions on an emergency basis. Doctors often recommend that people with serious allergies keep an epinephrine auto-injector available at all times. Epinephrine auto-injectors are sold under brand names including Adrenaclick, Auvi-Q, EpiPen, EpiPen Jr, and Symjepi, as well as non-branded generic products.

Epinephrine, also known as adrenaline, is a hormone and neurotransmitter. Epinephrine is believed to work in cases of life-threatening anaphylaxis by reversing swelling in the airways, shortness of breath, and low blood pressure.

How do I take it?
An epinephrine auto-injector should be administered in the outside of the upper thigh at the first sign of a serious allergic reaction. Different auto-injectors work in slightly different ways, but all products allow the user to self-inject automatically into the skin (subcutaneous) or muscle (intramuscular). Severe allergic reactions may require multiple doses of epinephrine.

Call 911 immediately after administering an epinephrine auto-injector.

Side effects
Epinephrine auto-injectors commonly produce side effects including fast or irregular heartbeat, weakness, nausea, vomiting, anxiety, nervousness, headache, dizziness, pale skin, sweating, trouble breathing, and tremors.

Rare but serious side effects listed for epinephrine auto-injectors include heart problems, infections at the injection site, and allergic reactions to epinephrine, sulfites, or other product ingredients.
