This is an iatroX educational summary of named Canada sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. The evidence source is pan-Canadian, but formularies, funded access, referral routes, public-health directions and service availability remain provincial or territorial.

Source and scope

This summary is bounded to the recommendations, population and decisions covered by Antifungal agents for common outpatient paediatric infections. Apply it with the current provincial or territorial pathway where implementation differs.

Source-attributed clinical priorities

  • Confirm a compatible dermatophyte pattern and use microscopy or culture when appearance is atypical or treatment fails.
  • Use topical therapy for limited skin disease and reserve systemic treatment for extensive, refractory or hair or nail involvement.
  • Avoid topical corticosteroid monotherapy, which can mask and extend dermatophyte infection.
  • Confirm uncertain or treatment-resistant disease with scraping because eczema and psoriasis commonly mimic tinea.

Practical assessment and management workflow

1
Describe site, border, scale, nail involvement, animal or contact exposure and previous steroid use.
2
Use topical antifungal treatment for limited skin disease and address moisture and footwear.
3
Obtain mycology before systemic therapy or when diagnosis, resistance or hair and nail involvement is uncertain.
4
Reassess nonresponse for adherence, wrong diagnosis, reinfection or resistant dermatophyte.

Safety, red flags and urgent escalation

  • Do not use potent topical steroid alone on suspected dermatophyte infection.
  • Review liver disease, pregnancy and interactions before systemic antifungal treatment.
  • Escalate inflammatory scalp disease, bacterial superinfection or widespread infection in immunosuppression.
