What to do

If you know what caused your child’s hives, try to remove or avoid it. Knowing the cause can also help prevent the hives from coming back.
Ask for advice at the pharmacy before using any medication.
If your child is scratching, try to distract them. You can also:
- Dress them in soft, loose clothing;
- Apply cold compresses to their skin;
- Use mild soap and keep their skin well moisturized (unless this makes the hives worse);
- Add baking soda (50–60 ml) to their bath water.
