What You'll Learn

Topical treatments: creams, gels, nail polishes, and liquids
Topical treatments for nail fungus include creams, gels, nail polishes, and liquids. These treatments are applied directly to the affected toenail or fingernail. While they can be effective in improving the appearance of the nail and treating the fungal infection, it is important to note that they may not completely penetrate the nail and the nail bed, which is necessary for a full cure.
Topical antifungal medications are typically applied multiple times a day, and it may take several weeks or months to see improvement. In some cases, it can take up to a year or more for the nail to fully return to normal. It is important to follow the directions provided by your healthcare professional and apply these medications exactly as directed to ensure effectiveness and reduce the risk of fungal recurrence.
Over-the-counter topical treatments are available, but their effectiveness may vary. Prescription topical treatments, such as efinaconazole (Jubilia), tavaborole (Kerydin), and ciclopirox (Penlac), are also options that require daily applications and may take up to a year to show noticeable improvement. These treatments are more suitable for early, superficial fungal infections.
In addition to creams and gels, antifungal nail polishes can be used as a topical treatment. These nail polishes are applied with a brush, similar to regular nail polish, and can help improve the appearance of the nail. However, they may not be as effective in curing the underlying fungal infection.
Overall, while topical treatments can be a good option for managing nail fungus and improving nail appearance, they may not always lead to a complete cure, especially for more severe infections. It is important to consult with a healthcare professional to determine the most appropriate treatment plan, which may include a combination of topical, oral, or other therapies.

Oral treatments: anti-fungal pills and medications
Oral treatments for nail fungus include anti-fungal pills and medications. Oral treatments are more commonly prescribed for onychomycosis, and they have shorter treatment times and better cure rates than topical preparations. Oral treatments can improve nail fungus within about three months.
Terbinafine is a medication used to treat fungal infections of the scalp, body, groin, feet, fingernails, and toenails. It is available only with a doctor's prescription. For onychomycosis, the recommended dosage for adults is 250 milligrams once a day for 12 weeks. Children's usage and dosage must be determined by a doctor. It is important to read the medication guide and patient instructions carefully and to ask your doctor if you have any questions.
Terbinafine tablets may be taken with or without food. However, it is best to take terbinafine oral granules with food. To clear up the infection completely, it is important to keep using this medication for the full treatment time, even if your symptoms begin to clear up or you begin to feel better after a few days. Since fungal infections may be very slow to clear up, you may need to take this medication for several weeks or months. If you stop taking the medication too soon, your symptoms may return. This medication works best when there is a constant amount in the blood. To help keep the amount constant, do not miss any doses, and take the doses at the same times every day.
It is important to note that appropriate studies on the relationship between age and the effects of terbinafine oral granules have not been performed in the geriatric population. While safety and efficacy have not been established, studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of terbinafine tablets in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require caution when taking terbinafine tablets. There are no adequate studies in women to determine infant risk when using this medication while breastfeeding. Therefore, it is important to weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Surgical treatments: nail removal and laser treatment
Surgical treatments for nail fungus may be considered if the infection is severe or persistent and other treatments have failed to resolve the issue. Two types of surgical treatments for nail fungus are nail removal and laser treatment.
Nail Removal
Nail removal involves the surgical or chemical removal of the nail. This procedure is typically reserved for severe cases of nail fungus where the fungus has not responded to other approaches. During the procedure, the infected nail is removed to eliminate the source of the infection and allow for the growth of a new, healthy nail.
Laser Treatment
Laser treatment is another surgical option for nail fungus. It is a safe and effective method that uses light energy to penetrate the nail and target the fungus. The light energy is absorbed by the fungal cells, causing their damage or death without affecting the surrounding tissues. Laser treatment may be particularly beneficial for individuals who cannot tolerate oral or topical antifungal medications, such as children, pregnant people, or those with underlying medical conditions. This treatment method usually requires multiple sessions spaced several weeks apart, and the cost can vary depending on the clinic and the number of sessions required.
The decision to undergo surgical treatment for nail fungus should be made in consultation with a healthcare professional, who can assess the severity of the infection and recommend the most appropriate treatment option. It is important to note that surgical treatments may not be covered by health insurance, and individuals should check with their insurance provider to understand their coverage options.

Home remedies: tea tree oil, Vicks VapoRub, and shower shoes
Toenail fungus, or onychomycosis, is a common fungal infection of the toenail. The most noticeable symptom is a white, brown, or yellow discolouration of one or more toenails. It may spread and cause the nails to thicken or crack.
Tea tree oil
Tea tree oil is an essential oil with antifungal and antiseptic properties. It can be used undiluted or diluted with a carrier oil, such as coconut oil. To use it undiluted, apply 3 drops directly to the fungus. To dilute it, add 5 drops of tea tree oil to half an ounce of carrier oil, mix, and then stir the mixture into a bucket of warm water. Soak your feet in this mixture for 20 minutes a few times a week. You can also apply the diluted mixture directly to the affected nail using a cotton swab.
It is important to note that tea tree oil may take a while to show results, and improvements may only be seen after 2 weeks of consistent use. Additionally, tea tree oil can cause side effects, so it is important to do a patch test before use.
Vicks VapoRub
Vicks VapoRub is a topical ointment that contains camphor and eucalyptus oil, which have antifungal properties. To use Vicks VapoRub, apply a small amount to the affected area at least once a day. An older 2011 study found that Vicks VapoRub had a positive clinical effect in treating toenail fungus. In this study, 83% of participants showed a positive treatment effect, with 27.8% achieving a mycological and clinical cure at 48 weeks.
Shower shoes
Fungal nail infections can occur when individuals come into contact with fungi in warm, moist areas, such as public showers and locker rooms. To prevent fungal nail infections, it is recommended to wear shower shoes or sandals when walking in these areas. This creates a barrier between your skin and the fungi, reducing your risk of infection.

Preventative measures: foot hygiene, breathable footwear, and dry socks
Preventing nail fungus is better than curing it. Nail fungus can be stubborn and difficult to get rid of. Even when the fungus is cured, the nail may still look unhealthy until a new nail grows in its place. While fingernails typically grow out in 4 to 6 months, toenails can take anywhere from 12 to 18 months to fully regrow.
Good foot hygiene and certain preventive measures can help you avoid nail fungus. Here are some tips to keep your feet healthy and fungus-free:
- Keep your feet dry. Avoid prolonged exposure to damp environments, as nail fungus thrives in warm, moist conditions.
- Choose breathable footwear and socks. Opt for shoes and socks made from materials that allow air circulation and help keep your feet dry. Avoid tight-fitting shoes that can make your feet sweat.
- Maintain proper foot hygiene. Wash your feet regularly with soap and water. Be sure to dry them thoroughly, especially between the toes, as moisture can lead to fungal growth.
- Disinfect tools and surfaces. If you use any tools for pedicures or nail care, be sure to disinfect them before and after each use. This includes nail clippers, files, and any other implements that come into contact with your nails.
- Avoid nail polish on infected nails. Do not apply nail polish, especially if you have an active toenail fungus infection. Nail polish can create a favourable environment for the fungus to thrive by trapping moisture and hindering airflow.
- Practice good nail habits. Keep your nails trimmed and well-groomed. Avoid ripping or tearing your nails, as this can create entry points for fungus to invade the nail bed.
By following these preventive measures and maintaining good foot hygiene, you can significantly reduce your risk of developing nail fungus and maintain healthy, fungus-free feet.
