You can find plenty of information on how to TREAT fugnal infections of the toenails, but little on how to PREVENT the infection. This page will do that for you.
If you are trying to treat nail fungus, read our Complete Guide to Toenail Fungus Treatment.
There are three groups of people that should put in extra effort to prevent fungal infections:
Fungus loves the warm, moist and dark environment of shoes. So you need to do everything you can to prevent fungus from getting hold in your shoes.
Never wear your shoes two days in a row. Let your shoes dry out for a day in-between.
Use an shoe sanitizer like the Sterishoe UV Shoe Sanitizer to kill fungus in your shoes using ultraviolet light (UVC).
This new in 2015 version of the Sterishoe works faster than the old version – only a 15 minute treatment is needed. It also includes a fan to dry the shoes.
Studies show that a single treatment destroys up to 99.9% of the microorganisms in shoes, including bacteria and fungi that cause foot odor, toenail fungus and athlete’s foot. You can get the sterishoe UV shoe sanitizer cleaner here.
Use the Sterishoe at least weekly on any shoes you wore that week.
Especially, if you are not using the ultravilet shoe sanitizer, use an anti-fungal spray like Lotrimin spray in your shoes after each time you wear a pair of shoes.
Lotrimin is made to spray on the skin but it is also good to spray inside shoes to help kill fungus.
It’s not a bad idea to use both the Sterishoe and the Lotrimin spray. Killing the fungus in your shoes is by far the most important thing you can do to prevent reinfection.
Use anti-fungal spray in your shoes each time you wear them.
Our favorite is Medline Remedy Antifungal Powder.
Put anti-fungal powder in your shoes a couple of times per week.
If you don’t have a prescription anti-fungal lacquer, use an OTC topical anti-fungal medication on your toenails daily. We provide our patients with a prescription for ciclopirox or Jublia nail lacquer. Learn more about topical treatments for nail fungus in our Complete Guide to Toenail Fungus Treatment.
For a good OTC choice try Fungi-nail. It is not as effective as the prescription medication, but the active ingredient, Undecyclenic Acid, is as good or better than other OTC anti-fungal nail treatments.
Use prescription (preferred) or OTC anti-fungal solution on your nails 2 – 3 times per week.
There is a tremendous amount of cross infection of fungus between nails and skin and between skin and nails. The same fungus that infects the toenails also causes athlete’s foot. So it is important to treat the skin of your feet also.
A good anti-fungal for your skin is Terbinafine Hydrochloride cream (trade name Lamisil).
If you have active Athlete’s Foot, then use it daily for 3 weeks. For prevention, use it a couple times each week.
For women who like nail polish, we recommend you use polish with anti-fungal properties like Nuwave Anti-fungal Nail Polish.
You should put on the topical anti-fungal listed above first and then put this polish on top of that.
If you share a home with someone with Athlete’s Foot or toenail fungus, or you frequent a gym, use flip-flops or slippers to protect your feet. Have a pair to wear in the shower too.
We recommend Vionic sandals more than any other brand. There is nothing special in how they protect you from fungus, they just have great arch support to help prevent pain from plantar fasciitis, bunions and other foot problems. So if you have any foot problems other than fungus consider an arch support sandal like Vionic.
To protect your feet from fungus in the shower, any shower shoe will do. Here are some inexpensive shower shoes that range from about $6 on up.
Don’t go barefoot in areas that are likely to be infected with fungus.
Wear moisture-wicking socks with anti-fungal properties. We recommend Xstatic socks which not only wicks moisture but contains silver fibers that can help kill fungus.
Since you wear shoes on only one foot but socks on both feet, socks are the best way to spread fungus from one foot to the other.
Wash your socks in hot water and dry them on a hot dryer setting.
Bleach is an excellent anti-fungal. Try a cap full of bleach in the wash when you wash your white socks. Obviously you would not want to do this with your colored socks.
If you have toenail fungus, read our Complete Guide to Toenail Fungus Treatment for a review of what current research shows to be the most effective treatments to cure fungal nail infections.
If you are in the Seattle area, contact us for an appointment. We will do everything possible to give you great looking nails and eliminate nail fungus forever.
