Comments from the Expert Advisory Group

Diagnosis is generally made on clinical grounds.

In case of treatment failure, it may be necessary to send samples for fungal culture.

Review modifiable risk factors in case of recurrence and refractory disease.

General Advice for Self-Care

Self-management of cutaneous candidiasis

Candidiasis is particularly likely to affect flexures in warm weather especially in those living with obesity. Keeping these areas dry, particularly skin folds can help prevent recurrence.

Self-management of oral candidiasis

Practice good oral hygiene

  • Brush teeth regularly
  • Use warm saline water as a mouth wash
  • Avoid use/overuse of antiseptic mouthwashes, as they alter the flora of the mouth
  • Rinse mouth out with water after using a steroid inhaler
  • Smoking is a risk factor for oral candidiasis and smoking cessation should be considered

Denture wearers:

  • Clean dentures with an anti-candidal preparation, such as 1% sodium hypochlorite solution
  • Remove dentures overnight
