Immunotherapy
Allergen-specific immunotherapy (allergy shots) for long-term management of environmental allergies.
Key Facts
- Only therapy that changes the immune system rather than suppressing symptoms
- ~50% excellent response, ~25% partial, ~25% no response
- Takes 6-12 months to see results
- Requires allergy testing (intradermal skin test or blood test) first
- Injections start twice weekly, eventually every 2 weeks
- Serious reactions (hives, collapse) rare (<1%)
- Does NOT help food allergies — only environmental allergens
