What is the appropriate treatment for hand, foot, and mouth disease in children?

Treatment of Hand, Foot, and Mouth Disease

Hand, foot, and mouth disease requires supportive care only, with oral analgesics (acetaminophen or NSAIDs) for pain and fever, intensive moisturization of skin lesions, and specific management of oral lesions to maintain hydration—there is no antiviral therapy available for this self-limited viral illness. 1

Symptomatic Pain and Fever Management

• Use acetaminophen or NSAIDs for a limited duration to relieve pain and reduce fever, as recommended by the American College of Rheumatology 1
• For infants younger than 6 months, administer 2 mL of 25% sucrose solution by syringe (1 mL per cheek) during painful feeding attempts 1
• Nonnutritive sucking with a pacifier reduces pain-related distress when used together with systemic analgesia in infants with oral lesions 1

Oral Lesion Management

Basic Oral Care

• Apply white soft paraffin ointment to the lips every 2 hours to prevent drying and cracking 1
• Use mild toothpaste and gentle oral hygiene practices 1
• Clean the mouth daily with warm saline mouthwashes or use an oral sponge for comfort 1

Topical Treatments for Moderate to Severe Oral Involvement

• Apply benzydamine hydrochloride oral rinse or spray every 3 hours, particularly before eating, to reduce inflammation and pain 1
• Use chlorhexidine oral rinse twice daily as an antiseptic measure 1
• For severe oral involvement, consider betamethasone sodium phosphate 0.5 mg dissolved in 10 mL of water as a 2-3 minute rinse-and-spit solution one to four times daily 1
• Barrier preparations such as Gengigel mouth rinse/gel or Gelclair are helpful for pain control 1
• Dilute mouthwashes by 50% if they cause discomfort 1

Dietary Modifications

• Eliminate tomatoes, citrus fruits, hot drinks, and spicy, hot, raw, or crusty foods that exacerbate oral pain 1
• Drink ample fluids to keep the mouth moist and prevent dehydration 1

Skin Lesion Management

Hand and Foot Care

• Apply intensive moisturizing creams to hands and feet, particularly urea-containing products 1
• Avoid friction and heat exposure to affected areas 1
• Do not use chemical agents or plasters to remove associated corns or calluses 1

For Itchy Lesions

• Apply zinc oxide 20% in a thin layer after gentle cleansing of affected areas 1
• Reapply as needed when itchiness returns 1
• For nighttime relief, apply zinc oxide followed by loose cotton gloves to create an occlusive barrier 1
• Avoid applying zinc oxide to open or weeping lesions 1

For Open Sores on Feet

• Wash feet daily with careful drying, particularly between the toes 1
• Avoid walking barefoot and wear appropriate cushioned footwear to protect open lesions 1
• Do not soak feet in footbaths, as this induces skin maceration and worsens open sores 1
• Do not use topical antiseptic or antimicrobial dressings routinely, as these are not recommended for wound healing 1

Infection Control and Prevention

• Hand hygiene with soap and water is the single most important preventive measure and is more effective than alcohol-based hand sanitizers 1
• Clean toys and objects that may be placed in children's mouths 1
• Avoid sharing utensils, cups, or food 1
• Children should avoid close contact with others until fever resolves and mouth sores heal 1

When to Return to Daycare

• Children can return to daycare once fever has resolved and mouth sores have healed, even if skin rash is still present 1
• Exclusion based solely on healing skin lesions is not necessary, as by the time HFMD is diagnosed, the child has likely had the infection for weeks 1

Monitoring and Red Flags

Signs Requiring Urgent Evaluation

• Persistent hyperthermia despite antipyretics 2
• Involvement of nervous system (lethargy, irritability, altered consciousness) 2
• Worsening respiratory rate and rhythm 2
• Circulatory dysfunction 2
• Elevated peripheral WBC count, blood glucose, or blood lactic acid 2

Follow-Up Timing

• Monitor for signs of secondary bacterial infection, including increased redness, warmth, purulent drainage, or worsening pain 1
• Reassess after 2 weeks if lesions are not improving with standard care 1
• If evidence of infection has not resolved after 4 weeks, re-evaluate and consider alternative diagnoses 1

Critical Differential Diagnoses

• Distinguish from herpes simplex virus infection, as HSV has available antiviral treatment (acyclovir) whereas HFMD does not 1
• Rule out Stevens-Johnson syndrome/toxic epidermal necrolysis if severe oral involvement is accompanied by systemic symptoms, as these require urgent specific treatment 1
• Consider Kawasaki disease (diffuse erythema vs. vesicular lesions), drug hypersensitivity reactions, syphilis, meningococcemia, and Rocky Mountain spotted fever in atypical presentations 1

Special Populations

• Immunocompromised patients may experience more severe disease and should be monitored closely 1
• Children younger than 3 years with EV-A71 infection and disease duration less than 3 days require particularly close monitoring for deterioration 2

Expected Course and Late Manifestations

• Most cases resolve in 7-10 days without sequelae 3
• Beau's lines (deep transverse nail grooves) may appear approximately 1-2 months after fever onset 1
• Periungual desquamation typically begins 2-3 weeks after onset of fever 1

Treatments NOT Recommended

• There are no specific antiviral agents approved for treatment of HFMD 1, 3
• Steroids and intravenous immunoglobulin show no significant advantage in mild cases and may prolong hospital stay in severe cases 4
• IVIG should only be considered for severe/complicated HFMD with neurological or cardiopulmonary involvement 3

Emerging Therapies

• Propolis (Anatolian propolis) showed promise in a 2025 randomized trial, reducing disease duration from 8.58 to 7.45 days and improving symptom scores, though this requires verification in larger studies with virological analyses 5
