Treatment of Hand, Foot, and Mouth Disease
Hand, foot, and mouth disease is a self-limited viral illness requiring only supportive care with oral analgesics (acetaminophen or NSAIDs) for pain and fever relief, combined with intensive skin care and oral hygiene measures. 1
Symptomatic Management
Pain and Fever Control
- Use acetaminophen or NSAIDs for a limited duration to relieve pain and reduce fever 1
- Oral lidocaine is not recommended for symptom management 2
- No antiviral treatment is currently available or approved for HFMD 2, 3
Oral Lesion Management
- Apply white soft paraffin ointment to the lips every 2 hours to prevent drying and cracking 1
- Clean the mouth daily with warm saline mouthwashes or use an oral sponge for comfort 1
- 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 mouthwash four times daily 1
- Use mild toothpaste and gentle oral hygiene practices 1
Skin and Foot Lesion Care
- Apply intensive skin care with moisturizing creams, particularly urea-containing products, to hands and feet 1
- Avoid friction and heat exposure to affected areas 1
- For itchiness, apply zinc oxide in a thin layer after gentle cleansing of affected areas; can be repeated as needed 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
Management of 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
- Avoid using chemical agents or plasters to remove corns or calluses 1
- Do not use topical antiseptic or antimicrobial dressings routinely 1
Monitoring and Follow-Up
Signs Requiring Closer Monitoring
- Monitor for signs of secondary bacterial infection: increased redness, warmth, purulent drainage, or worsening pain 1
- Immunocompromised patients may experience more severe disease and require close monitoring 1
- Watch for neurological complications (encephalitis/meningitis, acute flaccid myelitis, acute flaccid paralysis), particularly with Enterovirus 71 infections 1
- Reassess after 2 weeks if lesions are not improving with standard care 1
Expected Course
- Lesions usually resolve in 7-10 days without sequelae 2, 3
- Most cases are benign and self-limited 3
- Nail dystrophies (Beau's lines or nail shedding) may occur weeks after initial symptom onset 4
Prevention and Infection Control
Hand Hygiene
- Handwashing with soap and water is more effective than alcohol-based hand sanitizers and is the most important preventive measure 1
- Disinfect toys and objects that may be placed in children's mouths 1
Isolation and Return to Activities
- 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 1
- Avoid close contact with others until fever resolves and mouth sores heal 1
- Avoid sharing utensils, cups, or food 1
Healthcare Settings
- Follow standard precautions and good hand hygiene practices 1
Common Pitfalls to Avoid
- Do not prescribe oral lidocaine for oral lesions 2
- Do not seek antiviral therapy, as none is approved or available 2, 3
- Do not exclude children from daycare based solely on persistent skin lesions after fever and oral lesions have resolved 1
- Do not use topical antiseptics or antimicrobial dressings routinely on foot lesions 1
- Do not soak feet in footbaths when open sores are present 1
