Optimizing Adrenaline Administration in Anaphylaxis: Clinical Practice Considerations and Safety Insights.

BACKGROUND

Anaphylaxis is an acute, severe, and potentially fatal reaction marked by the fast onset of symptoms and organ involvement that may lead to death from vascular collapse or airway obstruction. Despite adrenaline (epinephrine) being the first-line medication for reversing anaphylactic symptoms, misconceptions about its safe and correct use persist and lead to improper administration.

METHODS

This review provides a comprehensive overview of clinical use of adrenaline autoinjectors (AAIs) in the management of anaphylaxis, key safety considerations, and pharmacokinetic/pharmacodynamic profile of three of the currently marketed AAIs.

RESULTS

When administered intramuscularly (IM) at the recommended dose for anaphylaxis, adrenaline is considered safe; however, adequate training in emergency care is essential to minimize dosage errors and mitigate safety risks. In specific situations, such as refractory anaphylaxis, intravenous (IV) administration is advised under specialized settings due to the potential risk of severe cardiovascular complications that can result from dosing errors.

CONCLUSION

Although adrenaline can cause mild and transient side effects even when administered correctly at the recommended dosage, the potential side effects should not deter its use in critical situations such as anaphylaxis. This review aims to highlight the role of AAIs in improving patient outcomes during anaphylactic emergencies.
