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
Patient Information
- Doses are oral and for adults unless otherwise stated
- Renal impairment dosing table
- Safety in Pregnancy and Lactation
- Drug interactions table. Extensive drug interactions for clarithromycin, fluoroquinolones, azole antifungals and rifampicin. Many antibiotics increase the risk of bleeding with anticoagulants.
- Visit the Health Products Regulatory Authority (HPRA) website for detailed drug information (summary of product characteristics and patient information leaflets). Dosing details, contraindications and drug interactions can also be found in the Irish Medicines Formulary (IMF) or other reference sources such as British National Formulary (BNF) / BNF for children (BNFC).
