Nail Fungus Treatments: Best Options for Clear, Healthy Nails

Nail fungus—also known as onychomycosis—affects millions of people and can cause discoloration, thickening, brittleness, and even pain in the toenails or fingernails.

While it's rarely dangerous, nail fungus is persistent and often difficult to treat without the right approach.

Whether you're dealing with a mild case or recurring infection, this guide explores the best nail fungus treatments in 2025, including over-the-counter remedies, prescription medications, home solutions, and advanced therapies.

What Causes Nail Fungus?

Nail fungus is typically caused by dermatophytes—a type of fungus that thrives in warm, moist environments. Common risk factors include:

  • Walking barefoot in public showers or gyms
  • Wearing tight or non-breathable footwear
  • Athlete’s foot spreading to the toenails
  • Poor foot hygiene or circulation issues (especially in diabetics)

It often starts as a white or yellow spot under the nail and can worsen over time if left untreated.

Top Nail Fungus Treatments in 2025

1. Over-the-Counter (OTC) Antifungal Treatments

These are ideal for mild to moderate infections or early-stage nail fungus.

Popular OTC Options:

  • Fungi-Nail® Antifungal Solution
  • Lamisil® (terbinafine) topical
  • Kerasal® Nail Renewal
  • Tinactin®, Lotrimin® sprays

How they work: These solutions usually contain clotrimazole, tolnaftate, or terbinafine, which inhibit fungal growth.

Best for: Early-stage infections, cosmetic improvement, and prevention.

2. Prescription Oral Medications

For stubborn or deep infections, oral antifungals offer the highest cure rate.

Most Common:

  • Lamisil® (terbinafine): 6–12 weeks
  • Sporanox® (itraconazole): Pulse therapy option

Effectiveness: Up to 70–80% cure rate, especially for toenail fungus.

Note: These drugs can impact the liver and require bloodwork monitoring. Not ideal for those with liver disease or on multiple medications.

3. Topical Prescription Medications

Topical prescriptions are a gentler alternative, especially for those avoiding oral meds.

FDA-Approved Options:

  • Jublia® (efinaconazole)
  • Kerydin® (tavaborole)
  • Penlac® (ciclopirox)

How they work: Applied daily for several months; can penetrate the nail plate better than OTC options.

Best for: Mild to moderate infections or in combination with oral therapy.

4. Laser Therapy for Nail Fungus

Laser treatments use heat or light energy to destroy fungal spores in the nail.

What to Expect:

  • Quick, painless sessions
  • Typically 2–4 treatments spaced a month apart
  • Cost: ~$500–$1,200 (not usually covered by insurance)

FDA-cleared devices: PinPointe®, Lunula Laser®, and GenesisPlus®

Best for: Recurrent cases, patients avoiding medications, or cosmetic restoration.

5. Home Remedies (Natural Alternatives)

While not FDA-approved, many people try home-based treatments, especially in early stages.

Common DIY Options:

  • Tea tree oil: Antifungal and antiseptic
  • Vicks VapoRub: Contains thymol and menthol
  • Apple cider vinegar soaks
  • Oregano oil

Effectiveness: Mixed results; best used for prevention or with other therapies.

How to Prevent Nail Fungus from Returning

Once treated, nail fungus can return—especially if habits don’t change. Here are ways to reduce the risk of reinfection:

  • Keep feet dry and nails trimmed
  • Disinfect nail tools and clippers regularly
  • Wear breathable shoes and cotton socks
  • Avoid walking barefoot in public areas
  • Treat athlete’s foot promptly

Fungus lives in shoes and socks—sanitize them or use antifungal powders/sprays regularly.

When to See a Podiatrist or Dermatologist

You should seek medical advice if:

  • The infection spreads or worsens despite OTC treatment
  • You have diabetes or circulatory issues
  • The nail becomes painful, black, or detaches
  • You’ve had recurrent infections

Early professional treatment leads to faster, more complete results.

Final Thoughts: Don’t Ignore Nail Fungus

While often seen as cosmetic, nail fungus can become painful and persistent if untreated. Whether you prefer natural methods, prescription medications, or advanced laser therapy, there are now more effective options than ever before.

Catching it early and committing to consistent treatment—often for several months—is the key to full recovery and clear, healthy nails.
