How to Get Rid of Toenail Fungus (What Works)
By PLACEHOLDER: Your Name · Updated July 2026
Toenail fungus is stubborn, and most of the “quick fixes” you see online do almost nothing for an established infection. The treatments that actually clear it are well known and backed by evidence, but they take patience. Here is what really works, ranked by how strong the science is, plus honest timelines and how to stop it coming back.
Key takeaways
- Prescription oral antifungals (terbinafine, itraconazole) have the highest cure rates and are the gold standard for moderate-to-severe infections.
- Prescription topical antifungals (efinaconazole, ciclopirox, tavaborole) work for milder cases but need months of daily use and clear less reliably.
- Toenails grow slowly, so even successful treatment takes 6-12 months or longer to show a clear nail.
- Oils and supplements have weak evidence for curing an established infection. They may help mild cases, appearance or prevention, not a serious infection.
First, make sure it really is fungus
Thick, yellow, crumbly nails are not always fungal. Psoriasis, trauma, and other nail conditions can look almost identical, and treating the wrong thing wastes months. A doctor can confirm the diagnosis with a simple nail clipping sent for testing. If you are unsure what you are dealing with, start with our guide to toenail fungus symptoms and causes before you spend money on any treatment.
See a doctor first if this is you
If you have diabetes, poor circulation, a weakened immune system, or you are not sure the diagnosis is fungal, see a doctor before self-treating. Oral antifungals in particular need medical supervision. This article is general information, not medical advice.
The treatments that actually work (ranked by evidence)
| Treatment | How it works | Evidence |
|---|---|---|
| Oral antifungals (terbinafine, itraconazole) | Pills that clear fungus from inside as the nail grows | Strongest. Highest cure rates; first-line for moderate-to-severe cases |
| Prescription topicals (efinaconazole, ciclopirox, tavaborole) | Medicated lacquer or solution painted on daily | Moderate. Works for mild-to-moderate cases; lower cure rates than oral |
| Nail debridement (in-office) | A podiatrist thins or trims the diseased nail | Supportive. Reduces thickness and helps other treatments reach the nail |
| Partial nail removal | Removing part or all of a badly infected nail | Case-specific. Reserved for severe or resistant infections |
| Laser therapy | Laser heats and damages the fungus | Limited/mixed. Not proven as reliable as antifungal drugs |
| OTC creams & medicated products | Antifungal creams and files | Weak for nails. Better for surrounding skin or athlete's foot |
| Tea tree oil, nail oils, supplements | Applied or taken to support nail health | Weakest. May help mild cases, appearance or prevention only |
1. Prescription oral antifungals (most effective)
Oral antifungals such as terbinafine (Lamisil) and itraconazole are the most effective option and the treatment dermatologists reach for when an infection is moderate, severe, or involves several nails. They work from the inside, clearing fungus from the nail bed while a healthy nail grows out to replace the damaged one.
A typical course runs several weeks (often around 6-12 weeks for toenails), but the visible result lags well behind because the nail has to grow out clear. Because these drugs are processed by the liver, your doctor may check liver function before or during treatment and will review any other medications you take. This is exactly why they need a prescription and supervision rather than being available over the counter.
2. Prescription topical antifungals
Prescription topicals like efinaconazole (Jublia), ciclopirox, and tavaborole are a good choice for mild-to-moderate infections, or when oral medication is not suitable (for example, due to liver concerns or drug interactions). You paint them on the nail daily.
The trade-off is honesty about the numbers: topicals have lower cure rates than oral antifungals and demand real commitment, often daily use for many months. They tend to work best on thin nails, early infections, and when the nail is filed down first so the medicine can penetrate.
3. In-office procedures
- Nail debridement: a podiatrist thins or trims the thickened nail. It does not cure the fungus on its own, but it relieves pressure and helps topical treatments actually reach the infection.
- Partial or full nail removal: reserved for severe, painful, or treatment-resistant cases. The nail is removed so treatment can be applied directly, or to give a healthy nail a chance to regrow.
- Laser therapy: widely marketed, but the evidence is mixed and limited. It is generally not a substitute for proven antifungal medication, and it is often not covered by insurance.
4. OTC and at-home options
Over-the-counter antifungal creams and medicated products can help mild cases and are genuinely useful for treating athlete's foot on the surrounding skin, which often feeds a nail infection. For an established nail infection, though, results are limited because the medicine struggles to reach the fungus under the nail plate.
5. Oils and supplements: the honest verdict
Tea tree oil, branded nail oils, and nail-support supplements are popular, but the evidence for curing an established infection is weak. At best they may help a very mild case, improve the look of the nail, or play a role in prevention. They are not a substitute for antifungal treatment on a real infection.

Realistic timelines: why this takes so long
Be patient, and expect setbacks
Toenails grow slowly, so a clear nail takes 6-12 months or longer to appear even when treatment is working. Do not judge success by week two. Just as frustrating, recurrence is common, so finishing treatment and then following prevention habits really matters.
The nail you see today is already grown. Treatment stops the fungus, but you are waiting for a fresh, healthy nail to grow in from the base and push the old one out. That is why even the most effective oral course does not deliver an instantly clear nail. Judge progress by whether new growth at the base looks healthy, not by the old damaged tip.
How to stop toenail fungus coming back
Prevention is the part people skip, and it is why so many infections return. Once you have cleared it (or while you are treating it), build these habits:
- Keep feet dry. Fungus thrives in warm, damp conditions. Dry thoroughly between toes after showering.
- Wear breathable shoes and moisture-wicking socks, and rotate shoes so they dry out.
- Treat athlete's foot promptly. Skin infection on the foot easily spreads to nails.
- Disinfect nail tools and do not share clippers or files with others.
- Protect your feet in communal areas like pool decks, gyms, and shared showers.
- Do not reinfect from old shoes. Consider disinfecting or replacing footwear worn during a bad infection.

The realistic path to a clear nail
Confirm it is fungus, match the treatment to how severe it is (oral for stubborn cases, topical for mild ones), stick with it for months, and lock in prevention habits so it does not return.
Frequently Asked Questions
What is the fastest way to get rid of toenail fungus?
There is no truly fast cure because the nail has to grow out clear. Prescription oral antifungals like terbinafine give the highest cure rates and the most direct route, but a clear nail still takes 6 to 12 months to grow in.
Can you cure toenail fungus without prescription medication?
Mild, early infections sometimes respond to over-the-counter antifungals or consistent home care, but established infections usually need prescription oral or topical antifungals. Oils and supplements alone rarely clear a real infection.
Why does toenail fungus keep coming back?
Recurrence is common because the fungus survives in shoes, on skin, and in communal areas. Keeping feet dry, treating athlete's foot, disinfecting tools, and wearing breathable shoes all reduce the chance of reinfection.
How long does it take to get rid of toenail fungus?
Expect 6 to 12 months or longer for a healthy nail to fully grow out, even when treatment is working. Progress is best judged by healthy new growth at the base of the nail, not the old damaged tip.
