Fingernail fungus, or onychomycosis, is a common infection caused by fungi entering and spreading in the nails. While it tends to affect toenails more than fingernails, it can develop in both. The infection is characterized by discoloration and gradual thickening of the nail. To treat fingernail fungus, medical intervention is typically required, and it cannot be cured quickly. Prescription antifungal medications are the most common treatment, and they can be administered orally or topically. In more severe cases, laser therapy or nail removal may be necessary. Preventative measures include good hygiene practices, such as regular handwashing, keeping nails short and trimmed, and avoiding walking barefoot in public spaces like pools and gyms.

Prescription antifungals
Fingernail fungus, or onychomycosis, is a common type of infection caused by fungi entering and spreading in the nails. While it can affect both toenails and fingernails, toenails are more commonly impacted due to the warm, moist environment of shoes. The infection typically develops gradually, but if left untreated, it can become chronic and cause structural damage to the nail beds, potentially spreading to other nails and the skin.
When dealing with fingernail fungus, prescription antifungals offer a more reliable solution than over-the-counter treatments or home remedies. While home remedies may help manage symptoms, medical treatments are necessary to effectively address the underlying infection. Prescription antifungals can cure most cases of fingernail fungus, but it is important to understand that the treatment takes time. Even with successful treatment, it can take several months for the affected nail to return to its normal state as you wait for it to grow back.
The duration of antifungal treatment for fingernail fungus typically lasts up to three months. During this time, the medication works to eradicate the fungus and promote the growth of healthy new nails. It is important to follow your doctor's instructions and complete the full course of treatment to ensure the infection is thoroughly addressed. In some cases, your doctor may recommend preventive measures or provide guidance on reducing the risk of recurrence.
Side effects from prescription antifungals are generally mild and well-tolerated. However, it is important to be aware of potential adverse reactions. Some possible side effects include redness and swelling, ingrown toenails, and stinging or burning sensations when applying topical treatments. Oral antifungal pills can also cause side effects, and your doctor will monitor you closely during the treatment period to ensure your safety and well-being.

Laser therapy
The American Academy of Dermatology Association (AAD) notes a lack of research on the safety and effectiveness of laser treatment for nail fungus. However, studies show promise in its effectiveness, particularly for at-risk populations such as those with kidney or liver disease or pregnant people. For example, a 2019 meta-analysis found that laser therapy can be effective and safe, with an overall success rate of about 63%. The CO2 laser therapy achieved the best overall results, and the 1064-nm Nd: YAG laser had a highly successful cure rate and a good safety profile.
The cost of laser therapy can be high, and insurance may not cover it. The number of sessions required will impact the overall cost. Additionally, laser therapy may not be suitable for everyone, and it is important to discuss the type of laser and the general success rate with the clinic before scheduling a session.

Surgery
Before considering surgery, doctors may recommend a range of other treatments to clear the fungal infection. These include antifungal medications, which can be highly effective in treating nail infections. Oral tablets and topical paints are commonly prescribed, and in some cases, a combination of both may be suggested.
Topical treatments involve applying an antifungal skin cream or solution directly to the nail or using a nail lacquer to paint the medication onto the surface of the nail. Trimming and soaking the nail before application can enhance the effectiveness of these treatments. Additionally, thinning the nail with a file or urea lotion can help the medication penetrate deeper into the nail.
For more severe infections, doctors may prescribe antifungal pills, such as itraconazole (Sporanox) or terbinafine (Lamisil). These oral medications are typically taken for up to 12 weeks and are known to support the growth of a new, healthy nail. However, it is important to note that these drugs may not be suitable for individuals with liver disease or heart problems and could potentially interact with other medications.
In cases where medication alone is insufficient, laser therapy may be recommended. This treatment utilizes high doses of light energy to destroy the fungi. While laser therapy is a promising approach, it is still considered fairly new, and more studies are needed to fully understand its effectiveness. Additionally, laser treatments tend to be costly and are usually not covered by insurance.

Non-prescription treatments
To prevent a fungal nail infection, it is recommended to wash your hands and feet often with soap, ensuring that you get between your fingers and toes. Keeping your fingernails and toenails short and trimmed straight across can also help. Wearing socks that wick away moisture is advisable, and if your feet sweat a lot, changing your socks once or twice a day or letting your feet cool by taking off your shoes can help prevent the infection. Using antifungal powder or spray on your feet and in your shoes can also be beneficial.
Additionally, it is important to throw away old pairs of closed-toe shoes, as fungi may be living in them. If you visit nail salons, choose ones that disinfect tools after each client, or bring your own file and clippers. Avoiding cutting your cuticles can help prevent tiny breaks in the skin that let germs in. It is also recommended not to share towels if someone else in your household has a nail fungus to prevent the spread of the infection.
Fungal nail infections can be challenging to treat, and they often do not go away without prescription antifungal medications. However, some self-care measures can help prevent the infection from spreading and improve the appearance and comfort of the nail.

Keep Good Nail Hygiene
Maintain short and trimmed nails, cutting them straight across. Regularly wash your hands and feet with soap, ensuring you clean between your fingers and toes.
Foot Care
If you tend to sweat a lot, change your socks once or twice a day, and opt for socks that wick away moisture. Allow your feet to cool down by taking off your shoes whenever possible. Use antifungal powder or spray on your feet and inside your shoes.
Nail Care
Avoid cutting your cuticles as this can cause tiny breaks in the skin that let germs in. If you visit nail salons, ensure they disinfect tools after each client. You can also bring your own nail file and clippers for added safety.
Avoid Sharing Personal Items
Fungal nail infections can spread through towels, clothing, socks, shoes, nail clippers, and moist surfaces. Avoid sharing these items with others, especially if they have a nail fungus.
Choose Footwear Carefully
Fungal nail infections thrive in warm, moist environments, so opt for well-ventilated shoes. Throw away old pairs of closed-toe shoes, as fungi may be living in them. Additionally, avoid walking barefoot in public spaces like swimming pools, gyms, locker rooms, showers, and saunas, as these are high-risk areas for fungal transmission.
Medical Conditions
Certain medical conditions can increase your risk of nail fungus, including a weakened immune system, cancer, diabetes, athlete's foot, psoriasis, and poor circulation. If you have any of these conditions, consult with your doctor or dermatologist for personalized advice on preventing fingernail fungus.
