Verywell Health / Sabrina Jiang

Toenail fungus is a common fungal condition that often starts after a rash on the foot spreads to the nails. When mild, it looks like white and yellow spots growing under the nail beds. But if left untreated, the fungus can grow severely by hardening the nails and spreading to other toes.

The fungus often begins in the form of athlete's foot between the toes or on the soles of the feet. At this stage, the fungal infection is easier to treat with over-the-counter medication. But Shari Lipner, MD, a board-certified dermatologist at New York-Presbyterian Hospital/Weill Cornell Medicine, told Verywell Health toenail fungus can be difficult to treat because of how slow the nails grow. "The more severe the toenail fungus, the thicker the nail, and the more nails involved makes it that much harder to treat the nails even with effective therapies," she says.

Diagnosing the fungal infection early is key to make treatments effective. Dr. Lipner recommends visiting a board-certified dermatologist to properly treat the infection if it grows to be too severe.

Here are a few of the best over-the-counter toenail fungus treatments on the market.

Active Ingredients: Tea tree oil, eucalyptus oil, and peppermint oil | Dose: Use like a standard body wash, apply and lather over the whole body. Leave soap on for 30 to 60 seconds before rinsing. | Uses: Cleanses bacteria and fungus all over skin; treats and helps prevent acne

FUNGINIX Healthy Nail Formula

Pros

Penetrates underneath nail beds
Tea tree and lavender sooth skin

Final Verdict

Toenail fungus may start out as a small annoyance, but it can spread and progress into something much more serious. "If left untreated over time more and more of the nails gets taken over by the thick yellow-white debris of the fungus making pedicures unmanageable," says Orit Markowitz, MD, founder and CEO of OptiSkin treatment center in New York City.

That's why treating the fungus early and often is so critical. If you're looking for an antifungal treatment that can address multiple concerns, we recommend the Terbinafine Hydrochloride AntiFungal Cream (view at Amazon). If you're looking for a treatment to target fungal growth under the nails, we recommend Fungi Nail Antifungal Ointment (view at Amazon).

What to Look for in a Toenail Fungus Treatment

Severity

Toenail fungus, if left untreated, can become a tough problem to treat and will greatly influence what medications you need. If the toenails are thick, yellowed, and left untreated for a long time, that could indicate you need either a prescription-strength product or to seek help from a board-certified dermatologist.

Location

Dr. Lipner says toenail fungus starts as athlete's foot. "It begins with a rash on the foot and spreads to the toenails," she says. Treating athlete's foot differs from toenail fungus, so pay attention to where your problem is on your foot. If it's athlete's foot, you can address the concern with antifungal ointments, sprays, and powders available over-the-counter.

Ingredients

Zinc undecylenate and undecylenic acid are both FDA-approved ingredients to treat toenail fungus. Also, if you seek help from a dermatologist, they will likely prescribe medications in the "azole" family. "The compound interferes with the synthesis of the fungal cell membrane," Dr. Lipner says, which essentially kills the fungus.

Type

Toenail fungus treatments can come in a variety of forms, but oral, topical, and homeopathic medications are the most commonly used for treating toenail fungus.

Oral: Oral medications have been proven effective, but they take time to work. "Lamisil also has the lowest side effect profile of the oral antifungal medications and works as a fungicidal which destroys a fungus by blocking its ability to 'breath' or make the oxygen molecules it needs to survive," says Orit Markowitz, MD. But there are several conditions that can make people ineligible for oral antifungal medications. The same underlying comorbidities, including chronic renal failure (with dialysis) and renal transplant, immunodeficiency, diabetes, cancer, and peripheral arterial disease that make someone more susceptible to toenail fungus also make them more at risk for side effects when taking the drugs.
Topical: Topical treatments (like amorolfine and ciclopirox) can help with minor toenail fungus. They cause fewer and less serious side effects. But, it's difficult for them to penetrate the nail plate so treatment is longer and efficacy is low. "Azole antifungals like JUBLIA inhibit fungal elements involved in the biosynthesis of critical fungal elements like fungal cell membranes," says Dr. Markowitz. She adds that, "topical therapies can be effective, but require lengthy and costly regimens without an established method for predicting outcome." It could mean daily topical treatments for 52 weeks.
Natural/Homeopathic: Natural preventative measures can be effective, but once fungus sets in, your best bet is a research-backed and FDA approved oral antifungal. Garlic has antifungal properties, and when used in a footbath can provide some relief. "Given that topical prescription remedies take at least 1 year of daily use to work in only 2/3 of mild to moderate cases it is difficult to recommend an off-label natural remedy treatment," says Dr. Markowitz. Keep in mind that a complete cure can take as long as 18 months. Plus, for fungal nail infections, a cure is not achieved at all in 20 to 25 percent of treated patients, per research.

Frequently Asked Questions

How long should I use a toenail fungus treatment?

Antifungal medications take some time to fight the fungus. Most products recommend twice daily application for one to two weeks. If at this time the condition has not improved, consult your doctor for treatment recommendations.
Can topical toenail fungus treatments cause irritation?

The active ingredients in most antifungal treatments are quite potent. That means they do have the power to cause burning, stinging, swelling, irritation, redness, bumps, and other irritation on the skin. If this occurs with use, consult your doctor. But, most people are able to use the antifungal creams and gels without problems and with healing, soothing effects.

What the Experts Say

"The most common presentation of toenail fungus is a white/yellow discoloration of the nail that is thick and filled with yellow/white keratin debris. The more severe the toenail fungus, the thicker the nail, and the more nails involved makes it that much harder to treat the nails even with effective therapies." —Orit Markowitz, MD, founder and CEO of OptiSkin treatment center in New York City.
