Anaphylaxis
Anaphylaxis is a severe, life-threatening allergic reaction that occurs rapidly after exposure to a trigger such as certain foods, insect stings, or medications. It can affect breathing, blood pressure, and multiple organ systems simultaneously. Prompt recognition and immediate treatment are critical and can save lives.
The allergists at The Medical Group of New Jersey provide comprehensive care, from emergency preparedness to long-term prevention, helping patients live safely and confidently with known allergies.
Symptom Onset & Emergency Evaluation
Anaphylaxis usually develops within minutes to several hours after exposure to an allergen. Recognizing the early warning signs is essential for quick intervention.
Common symptoms include:
- Widespread hives or swelling
- Tightness in the throat, wheezing, or difficulty breathing
- Rapid drop in blood pressure causing dizziness or fainting
- Nausea, vomiting, or diarrhea
Important: If you suspect anaphylaxis, use your epinephrine auto-injector immediately and call 911. Do not wait for symptoms to worsen.
Diagnosis
Anaphylaxis is diagnosed based on its sudden onset and involvement of two or more body systems (skin, airway, heart, or gastrointestinal).
In the emergency department, treatment focuses on stabilizing breathing and circulation, which may include oxygen, IV fluids, and medications to prevent recurrence. The first and most vital step is prompt administration of epinephrine.
Treatment & Ongoing Management
Once a trigger is identified, your allergist will develop a personalized emergency preparedness plan and provide education on how to prevent and respond to future episodes.
- Epinephrine auto-injector: Always carry two devices and ensure you and your caregivers know how and when to use them.
- Avoidance strategies: Identify and eliminate exposure to confirmed allergens.
- Emergency plan: Your allergist will provide a written plan for home, school, and work settings.
- Follow-up care: Schedule regular visits to review injection technique, device expiration dates, and symptom updates.
- Allergy immunotherapy or treatment with biologics: This therapy is considered when triggers cannot be fully avoided.
Long-Term Outlook
With the right preparation and expert guidance from The Medical Group of New Jersey, most people with a history of anaphylaxis can live safely and confidently.
Regular training refreshers, emergency plan reviews, and device checks are key to long-term safety and peace of mind.
