HOME CARE ADVICE FOR HAND-FOOT-AND-MOUTH DISEASE
- Reassurance: Hand-foot-mouth disease is a harmless viral rash.
- 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.
- 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.
- Fever Medicine: Give acetaminophen (e.g., Tylenol) or ibuprofen for fever above 102° F (39° C) or severe mouth pain.
- Quite contagious but a mild and harmless disease.
- Incubation period is 3-6 days.
