Hydrocortisone for HFMD Itch in Children
No, you should not prescribe hydrocortisone for itching due to hand-foot-and-mouth disease (HFMD) in children. HFMD is a self-limiting viral illness that resolves without treatment, and topical steroids are not indicated and may potentially be harmful.
Why Topical Steroids Should Be Avoided
The use of glucocorticoids in HFMD has been associated with worse outcomes. A case-control study found that glucocorticoid treatment was associated with a greater incidence of severe HFMD when used within 48 hours after onset or before critical disease developed 1. This raises significant safety concerns about any corticosteroid use in this viral infection.
Appropriate Management Approach
HFMD requires supportive care and parental counseling, not pharmacologic intervention for the rash:
- The disease is self-limiting, with symptoms resolving in a mean of 10 days 2
- Active communication and close monitoring are the cornerstones of management without complications 3
- Most cases improve with domiciliary care alone 3
What to Look For Clinically
When evaluating a child with suspected HFMD, identify these key features:
- Characteristic distribution: Vesicles, papules, or bullae on palms, soles, and oral mucosa 2
- Atypical presentations may involve arms, legs, face, and trunk (particularly with coxsackievirus A6) 2
- Prodromal symptoms: Mild fever and sore throat preceding the rash 4
- Self-limited course: Lesions typically resolve within 7 days 4
Treatment That Was Actually Used
In a systematic review of 1,359 pediatric HFMD cases, only 16% received any treatment, and when treatment was given, it was most commonly acyclovir or intravenous antibiotics (both inappropriate for uncomplicated HFMD), with topical steroids being mentioned but not recommended 2.
Expected Complications to Counsel About
Inform parents about benign late complications:
- Nail changes (onychomadesis) occur in 21% of cases, appearing approximately 3 weeks after symptom onset 2
- Desquamation occurs in 4% of cases, appearing approximately 2 weeks after symptoms 2
- These complications are self-resolving and do not require treatment 4
Critical Pitfall to Avoid
Do not confuse HFMD with conditions requiring steroids (such as atopic eczema or contact dermatitis). The vesicular morphology and characteristic distribution, combined with viral prodrome and contact history, should distinguish HFMD from steroid-responsive dermatoses 2, 3.
