See the guide →There is no single best toenail fungus treatment — there is a best one for how far the infection has gone, what your health looks like, and how long you’re willing to wait. The honest ranking below starts with the uncomfortable fact nobody on a product page mentions: a big toenail takes 12 to 18 months to grow out, so every treatment is judged over a year, not a month.
Step one: make sure it’s fungus
Thick, yellow, crumbly nails are not always fungal. Psoriasis, repeated pressure from shoes, running trauma and ageing can all look similar, and a large share of abnormal-looking nails turn out not to be infected at all. A doctor or podiatrist can clip a sample and send it to a lab. It’s worth doing before spending months — or money — on the wrong problem, and it’s required before most prescriptions anyway.
The treatments, ranked by evidence
| Treatment | How well it clears nails | Typical course | Main catch |
|---|---|---|---|
| Oral terbinafine | Best available — most people clear the fungus; about a third to half end with a fully clear nail | About 12 weeks of tablets, then the nail grows out | Prescription; liver check; not for everyone |
| Oral itraconazole | Good, a step behind terbinafine | Daily or “pulse” courses over months | Many drug interactions; heart-failure caution |
| Prescription nail solutions (efinaconazole, tavaborole, ciclopirox) | Modest — complete cure in a minority | Daily for about a year | Slow; some are expensive without insurance |
| Laser | Inconsistent results in studies | Several sessions | Usually paid out of pocket |
| OTC creams and polishes | Weak for the nail itself | Daily, open-ended | Barely penetrate a thick nail |
| Home remedies | Little good evidence | Open-ended | Easy to lose a year |
| Diet & lifestyle guides | Not tested as a cure | Ongoing | A support layer, not a treatment |

Mild, early infection (one nail, less than half affected)
This is where topical treatment has its best shot. A prescription nail solution applied every day, with the nail kept trimmed and thinned, is the evidence-based choice. Over-the-counter antifungal creams are labelled for skin, not nails, but they’re useful for the athlete’s foot that often feeds the nail infection — treat the skin too, or the nail gets reinfected.
Moderate to severe (several nails, thick, reaching the base)
Here oral terbinafine is the treatment with the numbers behind it. Your doctor will usually check your liver before starting, because rare liver injury is the serious side effect, and will ask about other medicines. Taste changes and stomach upset happen too. It isn’t suitable during pregnancy or with existing liver disease. Weigh it properly with the person prescribing it; our terbinafine comparison covers the trade-offs.
When it keeps coming back
Recurrence is common, and it’s the most demoralising part. The usual causes are untreated athlete’s foot, shoes that stay damp, shared nail tools, and a body that’s less able to fight off infection — higher blood sugar, poorer circulation, age. The practical fixes:
- Treat the skin between the toes at the same time as the nail.
- Rotate shoes so each pair dries fully; wear moisture-wicking socks.
- Keep your own clippers and clean them after each use.
- Wear sandals in gym showers and pool areas.
- Work on the general-health side: blood sugar, diet, activity.
That last point is where a structured guide can earn its place. Our review of Overcoming Onychomycosis explains what the Blue Heron program offers and where its sales page overreaches.

What about home remedies and laser?
Tea tree oil, vinegar, Vicks and friends are cheap and mostly harmless, but the studies behind them are small and the cure rates poor; we go through each in home remedies that work (and don’t). Laser is appealing because there’s nothing to swallow, yet results vary widely and it’s rarely covered by insurance. See what each option costs before committing.
Frequently Asked Questions
What is the fastest way to get rid of toenail fungus?
Oral terbinafine clears the fungus fastest, but the nail still has to grow out, which takes about a year for a big toe. There is no treatment that gives a clear toenail in weeks.
Can toenail fungus go away on its own?
Rarely. Left alone it usually spreads slowly to more of the nail or other nails.
How do I know my treatment is working?
Look at the base of the nail. A growing band of clear, normal nail pushing the damaged part forward is the sign. Take a monthly photo in the same light.
Is toenail fungus treatment safe for older adults?
Often, yes, but older adults are more likely to take other medicines and to have circulation or diabetes issues, so the choice should be made with a doctor.
