Prescribing Notes
- The Resuscitation Council do not recommend the use of auto-jectors by health care professionals for a number of reasons. Adults should receive 500 micrograms of adrenaline for the management of anaphylaxis.
- Adrenaline should be given immediately for an acute anaphylactic reaction (laryngeal oedema, bronchospasm and hypotension).
- Chlorphenamine injection is a useful adjunctive treatment given after adrenaline injection and continued for 24 to 48 hours to prevent relapse.
- Hydrocortisone injection is of secondary value in the initial management of anaphylactic shock because the onset of action is delayed for several hours, but should be given to prevent further deterioration in severely affected patients.
- Patients with known severe allergy should carry and receive instruction for the use of prefilled syringes (e.g. EpiPen®/Jext®) for self-administration. Patients should usually be prescribed two devices (four in children).
- Adrenaline for self-administration should be prescribed by brand name to ensure that the patient gets the device that they have been taught to use.
