(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:

1. Calm and reassure the person having the reaction.

2. Try to identify the allergen and have the person avoid additional contact with it.

3. If the person develops a rash, apply cool a compress and hydrocortisone.

4. Watch the person for signs of increasing distress.

5. Get prompt medical help.

If the allergic reaction is severe, call 911 immediately.
