Home Care Advice for Hand, Foot and Mouth Disease

  1. Antacid for Mouth Pain: Use a liquid antacid 4 times per day.
    • For younger children, put 1/2 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.
  2. 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 rather than a bottle. (Reason: The nipple can cause pain)
  3. Fever Medicine: Give acetaminophen or ibuprofen for fever > 102°F (39°C) or severe mouth pain
