Symptoms You May See

Anaphylaxis Symptoms Can Vary

The symptoms of anaphylaxis can be unpredictable. After contact with something you're allergic to (allergen), the symptoms can quickly develop within seconds or minutes. For some people, it may take hours. Sometimes the symptoms may even go away, only to come back 2, 4, or even 8 hours later.

Not everyone experiences the same symptoms. You may experience 1 or more of them. Some people may have stomach pain and a rash, while others might experience trouble breathing and swallowing. Whatever the symptoms, they highlight the importance of doing everything you can to avoid allergens in the first place.

When Is It Time to Take Action?

If you're experiencing symptoms, don't ignore them. Whether it's a mild rash or something serious, like your throat closing up, your response to this potentially life-threatening allergic reaction could be critical. Make sure you're familiar with what to do during a severe allergic reaction and follow your action plan from your healthcare provider.

Anaphylaxis is a medical emergency. Being familiar with the symptoms can help you spot them and know when to take action and use Auvi‑Q.

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 or call 1‑800‑FDA‑1088.
