While no treatment kills toenail fungus instantly, several approaches offer effective, fast-acting results. The most advanced option is laser treatment, which uses concentrated light to penetrate the nail and target the fungus without damaging the surrounding skin. Many patients see improvement after just a few treatments. Prescription oral antifungals like terbinafine (Lamisil) and itraconazole (Sporanox) are considered potent solutions, attacking the fungus from within and gradually clearing the infection as a new nail grows. These drugs require a prescription and can have side effects, so they are generally recommended for severe cases. Other options include hydrogen peroxide soaks and tea tree oil applications, which have antifungal properties but usually take longer to show results[1].
If the fungus does not respond to home treatments, it’s important to consult with a dermatologist or podiatrist. Medical professionals can prescribe stronger topical medicines such as ciclopirox (Penlac), efinaconazole (Jublia), naftifine (Naftin), tavaborole (Kerydin), or prescription-strength terbinafine. These are most effective after thinning the nail with a file or urea lotion, which helps the medication penetrate deeper. Oral antifungal pills may be prescribed for up to 12 weeks, especially for more severe infections[2].
Topical medications should be applied regularly and are most effective when paired with oral medications. In some cases, a healthcare provider might recommend thinning or removing the infected nail to increase the efficacy of the topical antifungal[3].
Over-the-counter treatments are available in the form of creams, ointments, sprays, and liquids, containing ingredients such as tolnaftate (Tinactin), clotrimazole (Lotrimin), or terbinafine (Lamisil). These must be used daily for several months. If there is no improvement, prescription medications or oral antifungal pills are usually more effective, though they may have side effects and require monitoring of liver function[5].
Other treatment options include nail removal (either partial or complete, surgical or nonsurgical) if the infection is deep or longstanding. In rare cases, permanent removal may be considered for chronically infected, painful nails[4].
Home remedies such as tea tree oil, oregano oil, and menthol-camphor ointments (like Vicks VapoRub) have shown some antifungal activity in small studies, but robust clinical evidence is limited. Maintaining proper nail hygiene, keeping nails trimmed and clean, and using antifungal powders or sprays as preventive measures can also help manage and reduce recurrence[7].
