HOME CARE ADVICE FOR WIDESPREAD RASHES (Pending Talking with Your Doctor)
- For Non-Itchy Rashes: No treatment is necessary, except for heat rashes which respond to cool baths.
- For Itchy Rashes:
- Wash the skin once with soap to remove irritants.
- Then give your child cool baths without any soap 4 times per day for 10 minutes whenever the itch is uncomfortable (caution: avoid any chill).
- Follow with calamine lotion or a baking soda solution (1 teaspoon in 4 ounces of water).
- Fever Medicine: For fever above 102°F (39°C), give acetaminophen (e.g. Tylenol) or ibuprofen.
- Contagiousness:
- If your child has a fever, avoid contact with other children and especially pregnant women until a diagnosis is made.
