Nail fungus FAQs

Onychomycosis is notoriously difficult to treat and cosmetically distressing. One in 4 patients don’t respond to therapy, and up to half of patients will experience relapse.”

What is a toenail fungus?

Nail fungus is a common condition.  Fungal nail infections are caused by various fungal organisms (fungi). The most common cause is a type of fungus called dermatophyte. Yeast and molds also can cause nail infections.

Fungal nail infection can develop in people at any age, but it’s more common in older adults. As the nail ages, it can become brittle and dry. The resulting cracks in the nails allow fungi to enter. Other factors — such as reduced blood circulation to the feet and a weakened immune system — also may play a role.

Toenail fungal infection can start from athlete’s foot (foot fungus), and it can spread from one nail to another. But it is uncommon to get an infection from someone else. (Source:  The Mayo Clinic Patient Information Page)

What are the symptoms of a toenail fungal infection?

The infection begins as a white or yellow spot under the tip of your fingernail or toenail. As the fungal infection goes deeper, nail fungus may cause your nail to turn yellow or brown, thicken and crumble at the edge. It can affect several nails. The clinical term is onychomycosis. Some patients feel embarrassed or uncomfortable by their toenails.

What factors may predispose me to fungal infections?

Men and older adults are more likely to develop toenail fungal infections, as well as those with poor circulation, past nail traumas, bad hygiene or weakened immune systems.

Athletes are also more likely to develop fungal infection than non-athletes. This could be because of repeated nail trauma or because sweaty feet are contained within tight, damp shoes, which can be a popular breeding ground for fungus.

How can I avoid getting toenail fungus?

This infection can be contagious.  If someone in your family has toenail fungus, exercise care about sharing towels, socks/shoes, nail clippers or nail brushes.  It is also relatively easy to re-infect.  If you are being treated for nail fungus, wear clean socks and thoroughly clean your shoes (or purchase new ones).

How can I treat toenail fungus?  Why ToeFX?

Nail fungus can be hard to treat, but it’s much easier to treat in the earlier stages of infection.  There is no “one-shot” pill or treatment available; the infection requires sustained treatment over weeks or months.  The ToeFX treatment is designed to be painless, side-effect free, drug-free and to clear up most mild-to-moderate cases within 3 months.
