There are no contraindications to using epinephrine for a life-threatening allergic reaction. This means that in normally healthy individuals, epinephrine will not cause harm if given unnecessarily. Possible side effects from epinephrine can include: rapid heart rate, pallor (paleness), dizziness, weakness, tremors and headache. These side effects are generally mild and subside within a few minutes.
3. Underlying cardiac diseases
People with heart disease or high blood pressure should speak to their physician about their cardiac medications and their need for epinephrine. Some medications (e.g. beta-blockers, ACE inhibitors) may interfere with the action of epinephrine and worsen the allergic reaction. (See Appendix K.)
Other Factors to Consider
ƒ Previous history
Previous history of anaphylaxis is a strong predictor of future anaphylaxis. However, at least 25% of adults and 65% of children presenting with anaphylaxis do not report a previous episode.10
ƒ Age
The highest incidence of anaphylaxis occurs in individuals aged 0 to 19 years. Food is the most
common cause of anaphylaxis in children, adolescents and young adults. In middle-aged and older adults, medications and insect venom are the most common causes.11
