(HealthDay News) -- Allergic reactions are sensitivities to allergens. From animal dander to foods, allergens may cause hives, itching, a rash and other symptoms.
For a mild-to-moderate reaction, MedlinePlus mentions these first aid steps:
- Calm and reassure the person having the reaction.
- Try to identify the allergen and have the person avoid additional contact with it.
- If the person develops a rash, apply cool a compress and hydrocortisone.
- Watch the person for signs of increasing distress.
- Get prompt medical help.
If the allergic reaction is severe, call 911 immediately.
