Candid mouth paint (clotrimazole) should be applied directly on the white patches inside the mouth using a clean cotton swab or earbud. It is meant for local action, so she should avoid swallowing immediately after application.
Apply a thin layer on the affected area.
Ask her to keep it in contact for 15–20 minutes without rinsing, eating, or drinking.
A small amount swallowed accidentally is usually not harmful, but ideally she should not swallow it intentionally.
Next Steps
If the thrush does not improve within 5–7 days, or if she develops pain or difficulty in swallowing, she should be reviewed by the doctor. In such cases, sometimes doctors prescribe antifungal lozenges (clotrimazole troches) or oral antifungal tablets (like fluconazole) for better control.
Health Tips
Since oral thrush is common with inhaler use, it helps to rinse the mouth with water and spit out after every inhaler use to prevent recurrence.
