Home Care (Read "Call Your Doctor…" first):
Antacid Solution for Pain Relief
Use an antacid solution 4 times per day:
- For younger children, put ½ teaspoon in the front of the mouth 4 times per day after meals
- Children over age 4 can use 1 teaspoon as a mouth wash after meals
Fluids
- Encourage favorite fluids to prevent dehydration
- Cold drinks, milkshakes, Popsicles, slushes, and sherbet are good choices
- Avoid citrus, salty, or spicy foods
- For infants, give fluids by cup, spoon or syringe rather than a bottle. (Reason: The nipple can cause pain)
- Solid food intake is not important
Fever Medicine
Give acetaminophen (e.g. Tylenol) or ibuprofen for fever > 102°F (39°C) or severe mouth pain.
Contagiousness
Quite contagious but a mild and harmless disease. Incubation period is 3-6 days. Can return to daycare or school after the fever is gone (usually 1 to 3 days).
Expected Course
The fever lasts 2 or 3 days. The mouth ulcers resolve by 7 days. The rash on the hands and feet lasts 10 days.
Call Your Doctor If:
- Signs of dehydration develop
- Fever lasts > 3 days
- Your child becomes worse or develops any of the "Call Your Doctor…" symptoms
