What are possible reactions to allergy injections and how are they treated?
Local reactions can occur at the site of the allergy injection and are the most common reactions. Local reactions may include redness, itching, and hard swelling. This type of reaction may be improved with an antihistamine and application of ice before and after allergy injections.
Severe allergic reactions can occur at any time, even if you are on the maintenance schedule. Signs of an allergic reaction include hives, flushing, extreme nasal symptoms, nausea, vomiting, wheezing, coughing, and difficulty breathing. This type of reaction requires immediate medical attention. If a severe allergic reaction occurs after your 30-minute wait in the clinic, you should call 911 or be seen in an urgent care or emergency department immediately.
