Getting rid of a fungal toenail takes patience, but you have several options ranging from daily topical treatments to full nail removal. Most cases clear up with antifungal medications, though treatment typically takes 6 to 12 months. In stubborn cases, the nail can be softened and removed chemically or taken off by a doctor, with full regrowth taking up to 18 months.
Why Fungal Toenails Are Hard to Treat
Nail fungus lives underneath and within the hard nail plate, which acts like a shield. Topical treatments struggle to penetrate deeply enough, and the nail itself grows slowly, so even when treatment kills the fungus, you’re waiting months for the damaged portion to grow out and be replaced by healthy nail. This is why there’s no quick fix. Whatever route you choose, you’re looking at a timeline measured in months, not weeks.
Topical Treatments You Apply at Home
For mild to moderate infections, prescription topical antifungals are the least invasive option. A medicated nail polish containing ciclopirox gets painted onto the infected nail and surrounding skin once daily. After seven days, you wipe the built-up layers off with alcohol and start fresh. This cycle continues for close to a year. Prescription antifungal creams like efinaconazole and tavaborole are rubbed into the nail after soaking to improve penetration.
Topical treatments work best when the infection hasn’t spread to the base of the nail or across multiple toenails. They’re slower and generally less effective than oral medications, but they avoid the systemic side effects that come with pills.
Oral Antifungal Medications
Oral antifungals are the most effective pharmaceutical option for nail fungus. You typically take a daily pill for 6 to 12 weeks, but it can take four months or longer for the infection to fully clear because the nail needs time to grow out. These drugs work from the inside, reaching the fungus through your bloodstream and accumulating in the nail tissue.
Success rates tend to be lower in adults over 65, partly because nails grow more slowly with age and circulation to the feet decreases. Your doctor will likely check your liver function before and during treatment, since oral antifungals can stress the liver in some people.
Removing the Nail Without Surgery
If the nail is severely thickened or deformed, removing it can give treatments direct access to the nail bed where the fungus lives. You don’t necessarily need a surgical procedure for this. A high-concentration urea gel (40%) softens and dissolves the damaged nail over several days when applied generously and covered with a bandage. After the nail softens enough, it can be peeled away without surgery. This is sometimes called chemical avulsion.
After the nail is off, antifungal medication is applied directly to the exposed nail bed, which dramatically improves how well the drug reaches the fungus. Your doctor may recommend combining chemical removal with a course of oral or topical antifungals for the best chance of clearing the infection completely.
Surgical Nail Removal
Surgical removal is typically reserved for cases where the infection is severe, painful, or hasn’t responded to other treatments. A doctor numbs the toe with local anesthesia and lifts the nail plate off the nail bed. This can be a partial removal (just the infected section) or a total removal of the entire nail.
Total nail avulsion is most effective for people who have one or just a few infected nails rather than widespread fungal involvement across many toes. In rare cases where the same nail keeps getting reinfected, the doctor may destroy the nail matrix (the tissue that produces the nail) so the nail doesn’t grow back at all. This is more common for chronic ingrown toenails than for fungus alone.
Caring for the Nail Bed After Removal
If your nail is removed, proper wound care prevents reinfection and complications. Keep the initial bandage on and dry for the first 24 to 48 hours. Use a plastic bag over the area when you shower. After that window, gently wash around the wound with clean water twice a day. Don’t scrub or soak the area, and avoid swimming.
Cover the exposed nail bed with a thin layer of petroleum jelly and a non-stick bandage, replacing it as needed. If a bandage sticks to the wound, use warm water to loosen it rather than pulling. A full toenail takes up to 18 months to completely regrow, though you’ll see noticeable coverage well before that.
Laser Treatment
Laser devices are marketed for nail fungus, and several have FDA clearance. However, that clearance is based on the device being technically similar to previously approved devices, not on clinical trial data showing it works. A 2019 analysis of 24 studies found that laser treatment produced complete clinical cure in only about 7% of patients, though roughly 67% saw some visible improvement. At this point, the optimal number and frequency of laser sessions remains unclear, and the treatment is rarely covered by insurance.
Over-the-Counter and Home Remedies
Mentholated chest rub (like Vicks VapoRub) has some limited evidence behind it. A clinical study published in the Journal of the American Board of Family Medicine followed 18 people who applied it daily for 48 weeks. About 28% achieved full cure, and another 56% had partial clearing. The active ingredients, including thymol, menthol, camphor, and eucalyptus oil, have antifungal properties in lab settings. Results were best against certain fungal species, with all five participants infected by those specific organisms achieving complete cure, while none of the 13 with other fungal types did.
This means mentholated ointment may be worth trying for mild cases, but it’s far from a sure thing. Other commonly suggested remedies like tea tree oil and vinegar soaks have even less clinical evidence. None of these are likely to work for thick, heavily infected nails.
Preventing the Fungus From Coming Back
Reinfection is one of the biggest frustrations with nail fungus. The same warm, moist environment inside your shoes that allowed the first infection will happily host another one. Taking specific steps during and after treatment makes a real difference.
- Disinfect or discard old shoes. Throw away or sanitize any shoes you wore before starting treatment. UV shoe sanitizers are one effective option. Wash all socks in hot water and detergent.
- Use antifungal powder or spray. Apply it to your socks and inside your shoes before putting them on, especially in hot weather or before workouts. These products won’t treat an active infection, but they prevent fungi from growing in your footwear.
- Rotate your shoes. Give each pair at least 24 hours to dry out completely before wearing them again.
- Keep feet dry. Change socks when they get damp, choose moisture-wicking materials, and dry your feet thoroughly after bathing, especially between the toes.
Athlete’s foot and toenail fungus are caused by the same organisms. If you develop athlete’s foot, treat it quickly before it spreads to the nails, where it becomes much harder to eliminate.
