What it is

Fungal nails, officially known as onychomycosis, are a relatively common condition that affects the nails — most often on the feet, though it can also develop on the hands. This infection occurs when fungi invade the nail bed, leading to gradual changes in the nail’s color, texture, and overall health.

Common causes of fungal nails include mold, yeast, and dermatophyte infections. These organisms typically enter through small cracks or breaks in brittle or damaged nails, allowing the fungus to grow beneath the nail’s surface. To help prevent fungal growth, it’s important to keep your feet clean and dry, wear breathable footwear, and trim your nails properly to reduce the risk of infection.

Symptoms of fungal nails often begin with yellow discoloration or white spots, usually starting in a small area beneath the nail but capable of spreading quickly. Over time, you may notice changes in nail texture such as crumbling, brittleness, or thickening. In more severe cases, the infection can cause a foul odor or even pain, making early diagnosis and treatment essential for restoring nail health.

Treatment Options

Fungal nail treatment is often simpler and more effective than most people realize.

While home remedies can sometimes help when used correctly, working with a specialist ensures a safer, faster recovery through a treatment plan tailored to your specific needs. At Horizon Foot & Ankle Institute, our experienced team will guide you through your options, typically including creams, polish, and oral medication, helping you choose the best approach to restore your nail health and confidence.

Topical Creams

Antifungal creams are one of the most accessible and effective treatments for toenail fungus. The process typically begins by thinning the nail — either through gentle filing or using a softening lotion — to help the medication penetrate deeper. After soaking your foot in warm water, the antifungal cream is massaged directly into the nail and surrounding skin, targeting the infection at its source.

Medicated Nail Polish

For those who prefer an easy, at-home approach, medicated antifungal nail polish can be an excellent option. The application is similar to regular nail polish, but you’ll also coat the surrounding skin to ensure full coverage. Each week, you remove the old polish and reapply a new layer. While results take time — sometimes up to a year — consistent use can gradually restore the health and appearance of your nails.

Oral Antifungal Medication

When faster results are needed, doctors often recommend oral antifungal medication as a first-line treatment. These medications work from the inside out to eliminate infection more rapidly than topical options. However, because they can cause side effects, they aren’t suitable for individuals with certain conditions like liver disease or congestive heart failure — making professional evaluation essential before beginning this form of treatment.
