What can a person expect after an allergy injection?

A wait time. Patients are usually monitored for a time period after an allergy shot to make sure that no reaction occurs. Most reactions are local & involve redness, swelling, and irritation within 1 inch of the injection site. Occasionally reactions become body-wide and cause itchy eyes, runny nose, tight throat, shortness-of-breath, and hives. If these symptoms occur, immediate treatment is necessary.
