Anaphylaxis symptoms
Symptoms of anaphylaxis can develop quickly and worsen within minutes. Common signs include:
- Difficulty breathing or wheezing
- Swelling of the face, lips, tongue, or throat
- Rapid or weak pulse
- Severe drop in blood pressure (shock)
- Hives, redness, or itching
- Nausea, vomiting, or diarrhea
- Dizziness or loss of consciousness
Causes / Dangers / Complications of Anaphylaxis
- Causes: Anaphylaxis is triggered by allergens such as foods, insect stings, medications, or latex. In some cases, no known allergen is identified (idiopathic anaphylaxis).
- Dangers: Without immediate treatment, anaphylaxis can lead to respiratory failure, cardiac arrest, or death.
- Complications: Even after initial treatment, a second reaction (biphasic anaphylaxis) can occur hours later. Repeated exposure to allergens without proper management increases the risk of future anaphylactic episodes.
Anyone at risk of anaphylaxis should carry an epinephrine auto injector at all times and have an emergency action plan in place. Consulting an allergist for testing and prevention strategies can help manage and reduce the risk of future reactions.

Frequently Asked Questions About Anaphylaxis Treatment
How is anaphylaxis treated?
The primary treatment for anaphylaxis is the administration of epinephrine through an auto-injector (e.g., EpiPen®). Epinephrine works quickly to reduce swelling, improve breathing, and stabilize blood pressure. Emergency medical attention should always follow the use of epinephrine to monitor for recurrent symptoms.
How does an epinephrine auto-injector work?
An epinephrine auto-injector is a pre-filled device designed to deliver a single dose of epinephrine into the thigh muscle. Once injected, it works within minutes to counteract the symptoms of anaphylaxis by:
- Constricting blood vessels to raise blood pressure.
- Relaxing airway muscles to improve breathing.
- Reducing swelling and hives.
When should epinephrine be used?
Epinephrine should be used at the first sign of a severe allergic reaction, such as difficulty breathing, swelling of the throat, or a sudden drop in blood pressure. Delaying treatment can increase the risk of complications.
Can anaphylaxis symptoms return after treatment?
Yes, a second wave of symptoms, known as biphasic anaphylaxis, can occur hours after the initial reaction. For this reason, it is critical to seek emergency medical care after using an epinephrine auto-injector, even if symptoms improve.
What are the side effects of epinephrine?
pinephrine is generally safe when used as prescribed. Possible side effects include:
- Increased heart rate.
- Tremors or shaking.
- Anxiety or restlessness.
- Temporary headache or dizziness.
- These effects are usually short-lived and less severe t
Can anaphylaxis be prevented?
Preventing anaphylaxis involves identifying and avoiding known allergens. Common strategies include:
- Reading food labels carefully.
- Communicating allergies in restaurants and medical settings.
- Wearing a medical alert bracelet.
- Carrying an epinephrine auto-injector at all times.
