Webinar: Treating anaphylaxis and what you need to know about Benadryl®

Step-by-Step Tutorial: Treating Anaphylaxis and Understanding Antihistamines

1. Understanding Anaphylaxis and Epinephrine:

   • Anaphylaxis is a severe allergic reaction that requires immediate treatment.
   • Epinephrine (EpiPen) is the first-line treatment for anaphylaxis as it helps counteract the allergic reaction by opening airways and raising blood pressure.

2. Role of Antihistamines:

   • Antihistamines are not a replacement for epinephrine in treating anaphylaxis.
   • Second-generation antihistamines like Reactine, Allegra, and Claritin are safer alternatives to older antihistamines like Benadryl (Diphenhydramine).

3. Administering Epinephrine:

   • If you suspect anaphylaxis, administer epinephrine immediately.
   • Hold the auto-injector firmly against the thigh for 5 seconds to deliver the dose.

4. Using Multiple Epinephrine Auto-Injectors:

   • Carry at least two epinephrine auto-injectors, especially if you have a history of severe reactions or live far from medical help.

5. Handling Side Effects of Epinephrine:

   • Side effects of epinephrine may include shakiness, increased heart rate, dizziness, and anxiety.
   • These side effects are temporary and typically resolve within 30 minutes.

6. Dealing with Expired Epinephrine Auto-Injectors:

   • Expired epinephrine auto-injectors can still be used up to six months past the expiration date.
   • Check for any discoloration or changes in the liquid before using an expired device.

7. Role of Antihistamines in Anaphylaxis:

   • Antihistamines can be used as a supplementary measure to control itching and hives in anaphylaxis.
   • Second-generation antihistamines are preferred over older antihistamines like Benadryl due to their safety profile.

8. Seeking Medical Help:

   • If you administer epinephrine, monitor for any recurrence of symptoms and be prepared to use a second dose if needed.
   • In case of long wait times at the emergency department, watch for signs of anaphylaxis and be ready to seek immediate medical attention if symptoms reappear.

9. Educating and Involving Children:

   • Educate children on the importance of carrying and using epinephrine auto-injectors.
   • Practice using the auto-injector with children to familiarize them with the process.

10. Consulting Healthcare Professionals:

    • Discuss any concerns or questions about anaphylaxis treatment with your doctor or allergist.
    • Follow the guidance provided by healthcare professionals for personalized recommendations.

Remember, always prioritize safety and follow the advice of healthcare professionals when dealing with anaphylaxis and the use of medications like epinephrine and antihistamines.
