What Are the Most Effective Treatments for a Fungal Nail Infection?

Fungal nail infections, also known as onychomycosis, can be hard to treat because the fungus lives inside and under the nail. One of the most effective treatments is an oral antifungal medication. These are pills that fight the fungus from the inside out and usually work better than topical treatments. However, because these pills can sometimes cause side effects, doctors will need to assess your overall health carefully before prescribing them. Topical treatments, such as antifungal creams, solutions, or nail lacquers, are applied directly to the nail and can help, especially if the infection is mild. Some newer approaches involve device-based treatments like lasers, though these methods are still being studied. Often, doctors may recommend a mix of these treatments to get the best results. Good nail care—keeping your nails clean, dry, and trimmed—also supports the treatment. Always follow your doctor’s instructions and complete your course of treatment to help clear the infection completely.
