What Is Anaphylaxis?

A Really Serious Allergy

For some people, an allergic reaction can affect the whole body, becoming much more severe and life threatening. These severe life‑threatening allergic reactions can come on fast and are known as anaphylaxis. Anaphylaxis is a medical emergency.

4 Things to Know About Anaphylaxis

The Symptoms Aren't Always the Same

Anaphylaxis affects everyone differently. Some people may have a skin rash and difficulty breathing or swallowing, while others may experience nausea and vomiting. Although there are common symptoms for anaphylaxis, they can vary drastically from person to person and reaction to reaction.

It's Caused by a Substance (allergen) Your Body is Allergic To

Things as simple as peanuts, shellfish, eggs, or a bee sting can cause an anaphylactic reaction to happen. The body sometimes quickly lets you know that it can't handle the substance (allergen) you're allergic to, while other times, symptoms can take hours to show up. The first line of defense against an anaphylactic reaction is to avoid your allergen.

Don't Wait to Get Tested for Severe Allergies

Ignoring allergies can be dangerous. Make sure to talk to your healthcare provider if you're experiencing symptoms, so they can help you identify what you're allergic to.

Treatment Is Available

Living with, or being at risk for, a severe allergy usually means carrying an epinephrine auto‑injector at all times, which is prescribed by the doctor. Epinephrine auto‑injectors usually come as a pair, because sometimes you need more than 1 dose to treat the anaphylactic reaction.



Auvi‑Q® (epinephrine injection, USP) is used to treat life‑threatening allergic reactions (anaphylaxis) in people who are at risk for or have a history of these reactions.

Important Safety Information

Auvi‑Q is for immediate self (or caregiver) administration and does not take the place of emergency medical care. Seek immediate medical treatment after use. Each Auvi‑Q contains a single dose of epinephrine. Auvi‑Q should only be injected into your outer thigh. DO NOT INJECT INTO BUTTOCK OR INTRAVENOUSLY. If you accidentally inject Auvi‑Q into any other part of your body, seek immediate medical treatment. Epinephrine should be used with caution if you have heart disease or are taking certain medicines that can cause heart‑related (cardiac) symptoms.

If you take certain medicines, you may develop serious life-threatening side effects from epinephrine. Be sure to tell your doctor all the medicines you take, especially medicines for asthma. Side effects may be increased in patients with certain medical conditions, or who take certain medicines. These include asthma, allergies, depression, thyroid disease, Parkinson’s disease, diabetes, high blood pressure, and heart disease.

The most common side effects may include increase in heart rate, stronger or irregular heartbeat, sweating, nausea and vomiting, difficulty breathing, paleness, dizziness, weakness or shakiness, headache, apprehension, nervousness, or anxiety. These side effects go away quickly, especially if you rest.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1‑800‑FDA‑1088.
