HOME CARE ADVICE FOR HAND-FOOT-AND-MOUTH DISEASE

  1. Reassurance: Hand-foot-mouth disease is a harmless viral rash.
  2. Liquid Antacid for Mouth Pain:  
    • Use a liquid antacid 4 times per day.
    • For younger children, put ½ teaspoon (2 ml) in the front of the mouth 4 times per day after meals.
    • Children over age 4 can use 1 teaspoon (5 ml) as a mouthwash after meals.
  3. Soft Diet:
    • 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.
  4. Fever Medicine: Give acetaminophen (e.g., Tylenol) or ibuprofen for fever above 102° F (39° C) or severe mouth pain.
  5. Contagiousness:  
    • Quite contagious but a mild and harmless disease.
    • Incubation period is 3-6 days.  
    • Can return to child care or school after the fever is gone (usually 2 to 3 days).
    • The rash is not contagious.
  6. Expected Course:  
    • Fever lasts 2 or 3 days.
    • Mouth ulcers resolve by 7 days.
    • Rash on the hands and feet lasts 10 days. The rash on the hands and feet may then peel.
  7. Call Your Doctor If:
    • Signs of dehydration develop
    • Fever present over 3 days
    • Your child becomes worse

And remember, contact your doctor if your child develops any of the "Call Your Doctor" symptoms.
