Ways to treat and prevent toenail fungus

Posted on

Toenail fungus, known medically as onychomycosis, is a common condition characterized by the thickening, discoloration, and potential disfigurement of the toenails. Often resistant to treatment, managing this fungal infection efficiently requires a multifaceted approach encompassing both treatment and prevention strategies. Effective treatment not only improves the appearance of the nails but also addresses the risk of recurrence, which is significant with toenail fungus.

Treatment Strategies for Toenail Fungus:
The first step in treating toenail fungus is obtaining a proper diagnosis. Often, what appears to be fungal infection could be psoriasis or another nail disorder. Once confirmed, the treatment options vary based on the severity and the specific type of fungus causing the infection.

  1. Topical Treatments: These are the first line of defense, especially in cases where the fungus is mild and has not penetrated the nail deeply. Antifungal lacquers like ciclopirox (Penlac) are applied daily to the affected nails and surrounding skin. Over the counter options include creams and ointments containing terbinafine or clotrimazole, which can be effective in early or mild cases. Topical treatments require diligent application and may take over a year to see complete results due to the slow growth of toenails.

  2. Oral Antifungal Drugs: More severe or entrenched infections often respond better to oral medications, which are more powerful and can help clear the fungus from the nail bed from within. Commonly prescribed drugs include terbinafine (Lamisil) and itraconazole (Sporanox), which help a new nail grow free of infection, slowly replacing the infected part. These treatments typically last from three to six months but can cause side effects like skin rash and liver damage, thus require monitoring through blood tests.

  3. Medicated Nail Polish and Creams: For infections that are resistant to other treatments, doctors might prescribe an antifungal nail polish called ciclopirox (Penlac), which is applied once a day to the affected nails and surrounding skin. After seven days, the layers of lacquer are wiped off with alcohol and fresh layers are applied. This treatment is usually long-term, extending over a year.

  4. Nail Removal: In extremely severe cases, temporary removal of the nail might be necessary to apply antifungal drugs directly to the infection under the nail. For some, permanently removing a nail that won’t heal might be the best course of action to eradicate the fungus and prevent recurrent infections.

  5. Laser and Light-based Therapies: Emerging treatments, including laser and photodynamic therapy, have shown promise in treating toenail fungus. These methods focus on killing the fungus directly without the side effects associated with systemic medications. However, these treatments can be expensive and often are not covered by insurance.

Prevention Strategies for Toenail Fungus:
Prevention is crucial when it comes to toenail fungus due to its recurrent nature. Following are some effective preventive measures:

  1. Maintain Hygiene: Regularly washing and thoroughly drying your feet helps prevent toenail fungus. Moist environments encourage fungal growth, so it’s essential to keep the feet dry and clean.

  2. Appropriate Footwear: Wear breathable shoes and change your socks daily to keep moisture away from the feet. When in communal bathing areas or locker rooms, wearing sandals can help reduce the risk of acquiring fungal infections.

  3. Use Antifungal Sprays or Powders: Regular use of antifungal sprays or powders on your feet and inside your shoes can decrease the risk of developing toenail fungus.

  4. Trim Nails Properly: Trim toenails straight across and avoid cutting them too short. This prevents bacteria and fungi from entering the nail bed, and reduces the incidence of ingrown toenails, which can lead to fungus infection.

  5. Avoid Nail Damage: Nail injury can make nails susceptible to infection. Avoid activities that repeatedly damage the nail or wear protective footwear.

  6. Sanitize Nail Tools: If you have your nails professionally treated, ensure the salon uses sterilized tools. Otherwise, bring your own. At home, sterilize your nail tools regularly.

  7. Manage Health Conditions: If you have health issues like diabetes, it's vital to manage them effectively. Diabetes significantly increases the risk of fungal infections due to reduced blood circulation and immune response, especially in the feet.

  8. Limit Artificial Nails and Polishes: The use of nail polish and artificial nails can trap moisture and fungi, exacerbating the problem. If you use nail polish, opt for antifungal types and allow nails time to breathe between applications.

In summary, treating and preventing toenail fungus involves a combination of medical intervention and lifestyle adjustments. While the treatment can be prolonged and sometimes challenging, persistence and adherence to preventative measures can lead to successful management of the condition. Early treatment enhances the likelihood of full recovery, and diligent application of preventative practices can help avoid the recurrence of the infection, maintaining the health and aesthetics of your toenails.
