Here are some things you can do to take care of your nails while you have a fungal nail infection: Keep your nails cut short and file down any thick areas. Don't use the same nail trimmer or file on healthy and infected nails.
Prescription topical treatments.
These products may work for early, superficial fungal infections because they kill fungi on the surface of the nail. Filing down the surface of the nail may enable them to penetrate more deeply into the nail or the nail bed. In studies, their cure rate averaged around 35%.
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.
Your health care provider may prescribe an antifungal cream, such as efinaconazole (Jublia) and tavaborole (Kerydin). You rub this product into your infected nails after soaking. These creams may work better if you first thin the nails.
Nail polish traps in moisture from your nailbed (the tissue below your toenail). Because fungi thrive in moist environments, wearing nail polish may make a fungal infection worse.
It can take between 6 and 18 months for the appearance of the affected nail to return to normal, and in some cases the nail may not look the same as before the infection. If the treatment is working, you should see a new healthy nail start to grow from the base of nail over the course of a few months.
I would always advise to file a thickened nail rather than cut it, this way you can do little harm to the nail and surrounding skin. A 'Diamond deb' nail file usually works best, filing the nail 2-3 times a week will usually keep the thickness reduced.
A severe case of nail fungus can be painful and may cause permanent damage to your nails. And it may lead to other serious infections that spread beyond your feet if you have a suppressed immune system due to medication, diabetes or other conditions.
The fastest way to eliminate the infection is through toenail laser treatment. Laser nail therapy specifically targets the microorganisms under your nail while leaving the keratin intact. In just a few treatments, the infection can be entirely eliminated.
Hydrogen peroxide
Hydrogen peroxide can kill fungus that grows on toenails. You can directly wipe hydrogen peroxide on your infected toes or toenails with a clean cloth or cotton swab. Hydrogen peroxide can also be used in a foot soak.
As the fungus advances, the color may change from yellow to brown. In some cases, a really nasty nail fungus case may even turn black and start to crumble.
Fungus thrives in moist and dark places so give it some light. Keep them naturally dry by exposing them to the sun whenever you can.
Toenails are made up of multiple layers stacked on top of each other. Toenail fungus can be tough to get rid of because it can get into and in between those layers. It may also sit on top of the nail or grow underneath it. In some cases, fungus can get into the cells that make the nail, called the nail matrix.
Answer by dermatologist Corey Georgesen, MD:
Toenail fungus doesn't usually spread to inside your body, like the stomach. The fungi require keratin, found in your hair, skin and nails. They survive best on the skin.
Although there are many potential causes of thick nails, a fungal infection is the most likely cause in the toenails. Other conditions, such as psoriasis or diabetes, may also cause thick nails to develop. The exact cause of thick nails will help decide a person's treatment to correct the condition.
In the worst case, a nail that has been filed too thin can lead to nail bed inflammation, bruising or even complete detachment of the stressed nail."
Nail fungus can be resistant to treatment and nails take a long time to grow out, so it can take several weeks or months for an infection to be fully resolved. You will know that the treatment is working and the infection is clearing up when you see growth of a new, healthy nail from the base of the nail bed.
Created: January 14, 2015; Last Update: June 14, 2018; Next update: 2021. Nail fungus can be very persistent. Topical treatment with nail polish may take up to one year.
Lamisil Terbinafine Antifungal Cream treats fungus all over the body, including athlete's foot, making it the best overall choice.
If you've noticed some discoloration or disfiguration of your toenails, you might be tempted to cover it up with bright red nail polish so nobody will notice. We hate to break it to you, but that's not a great idea. The reasons are that nail fungus grows in moist, dark environments, and can spread through nail polish.
Onychomycosis (nail fungus) in fingernails or toenails is more common than most people think, and many nail salons will provide a manicure and pedicure despite any nail infections you may bring with you.
Can you really pick up infections or nail fungus at salons? You can. Anytime your nails are getting wet, cut or filed—or your cuticles are being trimmed—it is an opportunity for bacteria and fungi to get in under the nail. Both bacteria and fungi can cause nail infections and are very common in the environment.
The danger with keeping your nail polish on too long is that the pigment in the nail polish can soak into the top few layers of the nail and dry it out, Dr. Rowland says. When that happens, fungus, yeast, bacteria, mold and mildew can develop underneath the nail plate, which can lead to long-term problems.
