Hymenoptera venom allergy severity classification
Mueller Grade
Grade 1 (Local)
Severity
High
💡 Clinical Pearl
Grade 1 local-only reactions do NOT typically benefit from VIT. However, if patient has extreme anxiety about future stings or high occupational/lifestyle risk (beekeeper, farmer, outdoor worker), VIT consideration is reasonable. Grade ≥2 = VIT strongly recommended given excellent efficacy and safety profile.
