Toenail fungus treatment

Toenail fungus can be spread by skin-to-skin contact, through shared objects like nail clippers or files, or through contact with shared surfaces, such as walking barefoot in public places like locker rooms.

Fungi love moist environments, so having sweaty feet or wearing tight-fitting shoes can make it easier for fungi to enter and infect the nail. Others who may be more likely to get toenail fungus include those with certain skin conditions (like athlete’s foot or psoriasis), repeated toenail injuries, weakened immune systems, conditions that affect blood flow (like diabetes or peripheral vascular disease), or a family history of nail fungus.

A provider can generally diagnose nail fungus based on your symptoms and by examining the nail. In more severe cases or if the diagnosis is less clear, a provider can take a sample of your nail during a visit and send it to a lab. Lab testing can identify the type of infection, if any, and the most effective treatment.

Let your provider know if you’re pregnant, trying to conceive, breastfeeding, or plan to be within the next 6 months. Your provider will partner with you to determine what treatment option is best and safest during pregnancy or while breastfeeding.

Wash your feet daily with soap and water, then dry them thoroughly. Using clean and disinfected tools, file the edges of your nails while keeping the cuticles intact. Wear breathable socks made of cotton or moisture-wicking materials, and change your socks at least daily and whenever they become sweaty. Wear breathable shoes made of materials like leather or mesh that fit with enough room for your toes. Consider wearing sandals or other footwear in public places like locker rooms, public showers, and public swimming pools. Consider treating your socks and shoes with over-the-counter antifungal powder. Avoid pedicures while being treated for toenail fungus.
