Toenail fungus treatment
Confirm the cause before choosing treatment.
Thick, discolored, brittle, or lifting nails may be caused by fungus, but trauma, psoriasis, and other nail disorders can look similar. An examination and, when needed, laboratory testing can guide the right plan.
What you may notice
Common fungal nail changes
Fungal nail infection, also called onychomycosis, often affects toenails and may involve one or several nails. Changes usually develop gradually.
Thickening
The nail can become difficult to trim and create pressure in shoes.
Crumbling or debris
Edges may become brittle while material collects beneath the nail.
Lifting or distortion
The nail may separate from the nail bed or change shape.
Why testing may matter
Not every thick or yellow nail is fungus
Trauma, repeated shoe pressure, psoriasis, aging, and other conditions can resemble fungal infection. Before a long course of prescription treatment, a nail clipping or scraping may be examined or sent to a laboratory when appropriate.
Examine the nail and skin
Review the pattern of nail change, athlete’s foot, pressure, trauma, and other health factors.
Confirm when needed
Microscopy, culture, or another laboratory method may help identify fungal infection.
Select a realistic plan
Consider the number of nails involved, severity, health history, medications, and treatment goals.
Treatment takes time
Toenail fungus treatment options
- Prescription medication applied directly to the nail for selected cases.
- Prescription oral antifungal medication when appropriate after reviewing health history and interactions.
- Trimming or thinning a thick nail to reduce pressure and improve comfort.
- Treatment of athlete’s foot or other fungal skin infection when present.
- Follow-up long enough to judge new nail growth rather than only the old damaged nail.
Toenails grow slowly, so visible clearing can take many months even when treatment works. Oral medication is not appropriate for everyone and may require laboratory monitoring.
Reducing recurrence and spread
Protect the nail and surrounding skin
Keep feet clean and dry, change socks regularly, wear breathable shoes, treat athlete’s foot, avoid sharing nail tools, and disinfect clippers after use. Wear protective footwear in communal wet areas.
Contact a medical professional promptly for increasing pain, redness, swelling, drainage, or an open area—especially with diabetes, poor circulation, reduced sensation, or immune suppression.
