Pet allergy shots: what to know

Shots, also called allergen immunotherapy, are considered after a clinician reviews your symptoms, exposure pattern, medical history, and allergy test results. The aim is to make the immune response less reactive; they are not a quick treatment for a reaction already happening.

Treatment requires appointments and observation because an injection can cause a local reaction or, rarely, a more serious allergic response. Tell the clinic about asthma, illness, pregnancy, and medicines before treatment. The exact allergen preparation and schedule are chosen by the treating specialist.

Keep a brief record of when sneezing, runny nose, or itchy eyes occur, how close you were to the animal, and what helped. Ask whether allergy testing confirms the suspected trigger and whether avoidance or allergy medication should come first.

Attend injections only through the service supervising your care and remain for the requested observation period. Follow instructions about exercise, illness, and medicines around appointments. Never use someone else’s allergy treatment.

Tell the clinic promptly about increasing reactions after an injection. Call emergency services for breathing difficulty, throat or tongue swelling, widespread hives, dizziness, or collapse after treatment or pet exposure.

Ask what the testing shows, what benefit is realistic for your symptoms, how long the treatment plan may take, what reactions to report, and what alternatives are available.
