What should you know about hives under eyes?

Hives are temporary areas of skin inflammation caused by histamine release. Around the eyes, the loose tissue can also become puffy; this deeper swelling is called angioedema. The eyelids may feel tight, itchy, or warm, while the welts can change shape or appear in new places. Triggers can include an infection, food, medicine, contact exposure, heat, or pressure, although a cause is not always found. Hives are a skin reaction, not proof that a particular food or product is responsible.

Keep the area cool with a clean, cool compress and avoid rubbing the eyelids. Stop any newly introduced eye, skin, or cosmetic product until a clinician has reviewed the episode. Note when the welts began, what touched the area, recent medicines or foods, and whether swelling moved beyond the eyelids. A pharmacist or clinician can advise whether an oral antihistamine is suitable; do not put non-prescribed creams close to the eyes. Repeated episodes may need assessment and a treatment plan.

Call emergency services immediately for swelling of the lips, tongue, mouth, or throat; trouble breathing, wheezing, faintness, or difficulty swallowing. Seek prompt medical advice if eye swelling is severe, vision changes, the eye is painful, fever accompanies marked redness, or symptoms follow a new medicine or sting. Arrange a clinical review when hives keep returning, last beyond a short episode, or interfere with sleep.

Ask whether the eyelid changes look like hives, angioedema, or another rash; whether your medicines could be contributing; what warning symptoms require emergency action; and which antihistamine plan is appropriate for you.
