Usage Notes
When using "过敏," it is important to specify what the allergy is to by using "对" plus the allergen. Unlike some other words for sensitivity, "过敏" strongly implies a physical or medical hypersensitivity. Avoid confusing it with "敏感," which can mean sensitivity in a broader emotional or perceptual sense.
