It's an extreme response to an allergen.

A life-threatening allergic reaction (anaphylaxis) is a severe reaction to a specific allergen, or allergic trigger. Common triggers can include but are not limited to food, biting or stinging insects, medications and latex. Exercise-induced anaphylaxis is also possible, and sometimes anaphylaxis has no apparent cause at all (this is known as idiopathic anaphylaxis).

What happens inside the body when anaphylaxis occurs?

The first step occurs when an allergen enters the body and causes antibodies (special proteins made by the body’s immune system) to form. These antibodies sensitize certain immune cells (called mast cells and basophils) to react the next time they encounter that specific allergen. When the allergen and these sensitized immune cells meet again, the antibodies cause the release of certain molecules (including histamine) that produce the immediate symptoms of anaphylaxis.

IMPORTANT SAFETY INFORMATION (the following information applies to both EPIPEN and its Authorized Generic)

Use EPIPEN (epinephrine injection, USP) 0.3 mg or EPIPEN JR (epinephrine injection, USP) 0.15 mg Auto-Injectors right away when you have an allergic emergency (anaphylaxis). Get emergency medical help right away. You may need further medical attention. Only a healthcare professional should give additional doses of epinephrine if you need more than two injections for a single anaphylactic episode. EPIPEN or EPIPEN JR should only be injected into the middle of your outer thigh (upper leg), through clothing if necessary. Do not inject into your veins, buttocks, fingers, toes, hands or feet. Hold the leg of young children firmly in place before and during injection to prevent injuries. In case of accidental injection, please seek immediate medical treatment.

Rarely, patients who have used EPIPEN or EPIPEN JR may develop an infection at the injection site within a few days. Some of these infections can be serious. Call your healthcare professional right away if you have any of the following at an injection site: redness that does not go away, swelling, tenderness, or the area feels warm to the touch.

Tell your healthcare professional about all of your medical conditions, especially if you have asthma, a history of depression, thyroid problems, Parkinson’s disease, diabetes, high blood pressure or heart problems, have any other medical conditions, are pregnant or plan to become pregnant, or are breastfeeding or plan to breastfeed. Be sure to also tell your healthcare professional all the medicines you take, especially medicines for asthma. If you have certain medical conditions, or take certain medicines, your condition may get worse or you may have longer lasting side effects when you use EPIPEN or EPIPEN JR.

Common side effects include fast, irregular or “pounding” heartbeat, sweating, nausea or vomiting, breathing problems, paleness, dizziness, weakness, shakiness, headache, feelings of over excitement, nervousness or anxiety. These side effects usually go away quickly if you lie down and rest. Tell your healthcare professional if you have any side effect that bothers you or that does not go away.
