Dangerous Allergic Reaction or Anaphylaxis: Emergency Response Required
Summary
Anaphylaxis is a severe allergic reaction that requires immediate medical attention. It can happen quickly and may be life-threatening if not treated promptly. Recognizing the symptoms and knowing what steps to take can make all the difference in an emergency situation.
What Is This & Why It Matters
Anaphylaxis is a rapid and severe allergic reaction that can affect various parts of the body. It often occurs within minutes of exposure to an allergen, such as certain foods, insect stings, or medications. The reaction can cause symptoms like swelling of the lips or throat, difficulty breathing, and hives. Immediate action is crucial to prevent serious complications. This handout provides essential steps to follow if you or someone else experiences anaphylaxis.
What You Should Do
- Use an EpiPen immediately if you suspect anaphylaxis. Inject it into the outer thigh, even through clothing if necessary.
- Call 911 right away after using the EpiPen, even if symptoms begin to improve.
- Have the person lie flat and elevate their legs to help blood circulation.
- Stay with the individual and keep them calm while waiting for emergency services.
- Loosen any tight clothing to aid breathing and comfort.
- If trained, administer CPR if the person becomes unconscious and stops breathing.
- Inform emergency responders about the person's allergy history and what triggered the reaction, if known.
- Go to the emergency room for further evaluation, as symptoms can return or worsen without further treatment.
What You Should NOT Do
- Do not delay using the EpiPen; time is of the essence in treating anaphylaxis.
- Avoid giving any food or drink during a reaction as it might worsen symptoms.
- Do not leave the person alone; continuous monitoring is crucial until help arrives.
- Refrain from attempting home remedies; they are ineffective against anaphylaxis.
- Do not administer any other medication unless instructed by a healthcare professional.
- Avoid assuming improvement after EpiPen use means full recovery; always seek medical evaluation.
- Do not hesitate to call for emergency help due to fear of overreacting; it's better to be safe.
Symptoms: Normal vs Warning Signs
Normal (Don't Worry)
- A rapid onset of hives or skin rash after allergen exposure.
- Mild swelling around lips or eyes that subsides with treatment.
- Tingling sensation in mouth or throat during initial reaction phase.
- Slight dizziness that resolves with proper positioning and care.
- Temporary increase in heart rate due to adrenaline response.
Call Your Doctor If...
- Persistent difficulty breathing or shortness of breath despite EpiPen use.
- Swelling that spreads to the tongue or throat causing airway obstruction.
- Severe drop in blood pressure indicated by fainting or loss of consciousness.
- Chest pain or tightness that could indicate heart involvement.
- Wheezing or persistent cough that worsens over time.
- Rapid, weak pulse signaling cardiovascular distress.
- Confusion or disorientation indicating insufficient oxygen supply to the brain.
- Bluish skin color (cyanosis) around lips or extremities due to lack of oxygen.
- Reappearance of symptoms after initial improvement post-EpiPen use.
FAQ
What is an EpiPen, and how does it work?
An EpiPen is a device containing epinephrine, a medication that quickly reverses severe allergic reactions by relaxing muscles in the airways and tightening blood vessels.
Can I use someone else's EpiPen in an emergency?
While it's ideal to use your prescribed EpiPen, using another's is better than no treatment at all. Always inform medical professionals afterward.
How long does it take for an EpiPen to work?
Epinephrine generally starts working within minutes. However, its effects may be temporary, so immediate medical follow-up is essential.
What should I do if I don't have an EpiPen?
Call 911 immediately and inform them about the situation. Stay with the person, keep them calm, and follow any instructions given by emergency operators.
Is it possible for anaphylaxis to recur?
Yes, biphasic reactions can occur hours later without additional allergen exposure. Always seek emergency care even if symptoms initially improve.
