It’s easy to get a fungal nail infection. If you have a fungal infection on your foot, the fungus can spread to one or more of your nails. This is quite common.
You can also catch a fungal nail infection in a warm, moist place such as a pool deck or locker room. If someone else has a fungal infection and walked barefoot there, all you have to do is walk barefoot in the same area.
Having wet nails for a long time can also lead to nail fungus. Some people develop it when they wear the same pair of sweaty shoes or boots every day. Fingernails that are wet for hours at a time due to a job or hobby are also susceptible.
Treatment usually begins with your dermatologist trimming your infected nail(s), cutting back each infected nail to the place where it attaches to your finger or toe. Your dermatologist may also scrape away debris under the nail. This helps get rid of some fungus.
To completely get rid of the infection, most people also need one or more of the following treatments:
Medicine you apply to the nail: If you have a mild infection, a medicine that you apply to your nails may get rid of the infection. This treatment helps keep new fungus out while the nails grow. Fingernails typically grow out in four to six months. Toenails take longer, usually takes 12 to 18 months.
Probably the most difficult part of this treatment is remembering to use it as often as prescribed. Some treatments must be applied every day. Others you apply once a week. To get the best results, it’s essential that you apply these medicines exactly as directed.
The US Food and Drug Administration (FDA) has approved the following medicines that you apply to the nail to treat nail fungus:
Amorolfine
Ciclopirox
Efinaconazole
Tavaborole
