Toenail Fungus Treatments, Compared: Pills, Topicals, Laser, and What Cures
There are five ways to treat toenail fungus, and they don't work equally. The difference between the best and the worst is not a few percentage points; it's the difference between a nail that clears in most men and one that clears in fewer than one in ten. Most men never see those numbers because the products are sold on hope, not results.
This guide puts the options side by side: what each one is, how well it works in trials, what it costs, and who it suits. It assumes the diagnosis is confirmed. If it isn't, start with is it toenail fungus?, because none of this helps a nail that was never infected. Toenail fungus: what works has the one-page ranking if you want the short version first.
One word on "cure". Trials measure two things: the fungus gone from the lab test (mycological cure) and the nail fully normal to look at (complete cure). Complete cure is the number that matters to you and it's always the lower one. The figures below are complete cure unless stated.
The pill: terbinafine
What it is. A tablet, taken once a day for 12 weeks for toenails. It travels through the blood into the nail bed and keeps working there for months after the last dose, which is why a 3-month course treats a 12-month problem.
How well it works. The best of the lot. In the trials that got it approved, about 4 men in 10 reached a completely normal nail and about 7 in 10 were fungus-free on the lab test. Real-world numbers are a little lower, and the odds fall with age, with how much of the nail is involved, and with slow circulation.
What to know before you take it. It's a generic and cheap. It's processed by the liver, so doctors check a liver blood test before starting and sometimes during; serious liver harm is rare but real, and anyone with liver disease is steered elsewhere. Some men notice a change in taste or smell, which usually resolves after the course but occasionally lingers. It interacts with a few medications, including some antidepressants and heart drugs, so bring your full list. It doesn't have the cholesterol-drug interaction that the other pill has.
Who it suits. Most men over 40 with a confirmed infection that involves more than the tip of the nail, more than a couple of nails, or the nail's base. Also anyone who has already failed a year of topical treatment.
The other pill: itraconazole
What it is. A capsule, taken daily for 12 weeks or in one-week "pulses" each month for three months.
How well it works. Clearly less than terbinafine: roughly 1 man in 7 reaches a completely normal nail. It's the pill for cases where terbinafine can't be used or the lab finds a yeast or mold rather than a dermatophyte.
What to know. This one has the interaction problem. It blocks the enzyme that clears many common drugs, and some cholesterol medications (simvastatin and lovastatin in particular) can't be taken with it at all. It also carries a warning for men with heart failure. For a man over 40 on a statin, that alone usually settles the choice.
Prescription topicals
Three prescription liquids or lacquers, painted on the nail daily for 48 weeks. They avoid the liver entirely and suit mild infections: the tip of the nail, less than about half its area, the base not involved, and no more than three or four nails.
Efinaconazole solution (Jublia). The best of the topicals. About 1 man in 6 reached a completely normal nail after a year in its trials, and about half were fungus-free on the lab test. It penetrates the nail better than the older lacquers and doesn't need filing. It's expensive without insurance.
Tavaborole solution (Kerydin). Similar idea, slightly weaker results: well under 1 in 10 complete cure in its trials.
Ciclopirox lacquer (Penlac). The old one and the cheap one; a generic exists. Applied daily, removed with alcohol once a week, with the nail trimmed and filed monthly. Complete cure is low, around 1 in 12 to 1 in 18, and it's a full year of daily discipline for that.
How to raise the odds with any topical. File the nail thin first, and keep it thin; a podiatrist can grind it down properly in minutes. Treat the skin between the toes at the same time. And apply every day; the failures in the trials are mostly people who stopped.
Does Lamisil cream work on toenail fungus? The drugstore shelf
No. Lamisil AT and the other athlete's foot creams are terbinafine or a cousin of it, and they work on skin because skin is where they can reach; a nail plate stops them. They're the right thing for the peeling between your toes and the wrong thing for the nail. The rest of the over-the-counter "fungal nail" shelf is mostly urea, which softens the nail for filing, or a whitener; none has cure evidence, and home remedies and laser goes through it product type by product type.
Laser
A clinic treatment that heats the nail to damage the fungus, sold for several hundred to over a thousand dollars and rarely covered by insurance. Its clearance is for a "temporary increase in clear nail", a cosmetic claim, and the best review of the trials found small, inconsistent studies with clearance rates well below the pill; home remedies and laser has the evidence in full and the one case where laser plus a topical is worth trying.
Thinning the nail: the step everyone skips
A podiatrist can file or grind a thick nail down to a thin plate in one visit, and a 40% urea cream at home does a slower version over weeks. It's not a cure on its own. It matters because every other treatment works better on a thin nail: less material for the fungus, less pressure in the shoe, and far better penetration for a topical. It's the cheapest improvement on this page.
Combining treatments
Pill plus topical does better than either alone in several studies, particularly for stubborn cases, because they reach the fungus from two directions. Pill plus nail thinning is standard practice. Topical plus laser is what clinics offer men who can't take the pill. Ask the podiatrist which combination fits your nail; the answer depends on how much of it is involved and how long it has been there.
Should the nail be removed?
Sometimes, and rarely on its own. There are two ways to take a nail off: a chemical avulsion, where a high-strength urea paste under a dressing softens the nail over a week or two until it lifts away without cutting, and a surgical avulsion, done under local anesthetic in the office. Removing the nail doesn't cure the infection by itself, because the fungus is in the nail bed too and the new nail grows straight into it; studies of avulsion alone show poor cure rates. It earns its place for a nail so thick or painful that nothing can be applied to it, or paired with a topical painted on the exposed bed while the new nail grows. A permanent removal is a last resort for a man who has been through repeated courses and wants no more nail to infect. Ask about it if the nail hurts in every shoe; otherwise thinning does most of the same job with none of the downtime.
Choosing
What each costs, roughly. Generic terbinafine is the cheapest by far: the 12-week course runs to a few tens of dollars at most pharmacies with a discount card, plus the blood test. Generic ciclopirox lacquer is tens of dollars a bottle, and a year takes several bottles. Efinaconazole (Jublia) and tavaborole (Kerydin) run to hundreds of dollars a bottle without insurance coverage, and a year usually takes more than one bottle. Laser is several hundred to over a thousand dollars for a course, almost never covered. Nail thinning by a podiatrist is an office visit. Cash prices move; check a discount-card price before you fill anything.
- Confirmed, more than the tip, or several nails, no liver disease: terbinafine, with a liver test first and the topical on top if the podiatrist suggests it. Highest odds, lowest cost.
- Mild, a tip or an edge, one to three nails: a prescription topical for a year, nail kept thin, skin treated.
- Can't take the pill (liver disease, interactions, your choice): topical plus thinning, laser optional.
- On a statin: terbinafine is usually fine; itraconazole usually isn't. Confirm with the prescriber.
- Diabetes or poor circulation: the podiatrist decides, and sooner rather than later, because these nails cause more trouble.
Whatever you choose, the calendar is the same: 12 to 18 months for a big toenail to grow out clear. The 12-month protocol covers what to do in each of them.
Bottom line
The pill cures the most, costs the least, and needs a blood test and a medication check first. The prescription topicals cure some mild cases with a year of daily use. Drugstore products and laser have no cure evidence worth the money. Nail thinning improves all of them. Get the diagnosis, bring your medication list, and pick the route with the podiatrist. Bring the doctor-prep checklist so the visit covers the liver test and the interactions.
