How should we treat thick yellow toenails in an older adult?

Question

My mother's toenails have become thick, yellow and difficult to cut. She is embarrassed to wear sandals. Is this just aging, or a fungal infection that should be treated? What actually works?

Thick, yellow toenails in older adults are most commonly caused by a fungal infection called onychomycosis, though they can also result from trauma, eczema, or psoriasis. It is rarely just normal aging alone. To address your mother's discomfort, start with these practical steps: Get a professional diagnosis first: Visit a podiatrist or dermatologist who can scrape nail debris for laboratory testing. This confirms whether it is fungal or something else, preventing unnecessary treatments.Try over-the-counter antifungals: Topical creams or lacquers containing ciclopirox or tofacenbef have modest success rates, but consistency is key. Apply them daily for at least six months, as toenails grow slowly.Prescription medications may be needed: For extensive cases, doctors often prescribe oral antifungals like terbinafine or itraconazole. The FDA warns these drugs can have side effects on the liver, so regular blood tests are required. Check with a pharmacist to ensure these do not interact with her other heart or blood pressure medications.Prevent reinfection: Keep feet dry, wear breathable cotton socks, and alternate between two pairs of shoes to allow them to dry out. Disinfect her slippers and socks with bleach or Lysol wipes to kill lingering spores. While complete cure rates for oral medications are around 50 percent, combination therapy often yields better results. Encourage her to be patient, as it takes up to a year for a healthy nail to fully grow out. If she remains embarrassed, cosmetic nail clippers and thinning files can help manage the appearance while treatment takes effect.
