Nail Fungus Treatment in Glendale, AZ
Nail fungus (onychomycosis) is one of the most persistent and undertreated nail conditions in podiatric medicine. Many patients spend months or years applying over-the-counter products without success before finally seeking professional care — by which point multiple nails are often affected and the infection is deeply established. At Sole Foot & Ankle Specialists, our board-certified podiatrists offer accurate nail fungus diagnosis and a full range of advanced treatment options to restore healthy, clear nails for patients throughout Glendale, Phoenix, Peoria, and Sun City, AZ.
Understanding Nail Fungus (Onychomycosis)
Onychomycosis is a fungal infection of the nail plate and/or nail bed caused most commonly by dermatophyte fungi (the same organisms behind athlete’s foot), though yeasts (Candida) and non-dermatophyte molds can also be responsible. The infection penetrates and colonizes the keratin of the nail, where it feeds and reproduces in a protected microenvironment that is largely inaccessible to topical treatments that cannot penetrate the nail plate effectively.
Nail fungus is far more common than most people realize — it affects an estimated 10% of the general adult population and up to 50% of adults over 70. It is also chronically underdiagnosed because nail changes can mimic other conditions such as psoriasis, nail trauma, or lichen planus. Accurate diagnosis through nail sampling is important to confirm the fungal etiology before committing to a prolonged treatment course.
Symptoms of Nail Fungus
Fungal nail infection progresses slowly and worsens without treatment. Signs include:
- Yellow, white, brown, or orange discoloration of one or more toenails
- Thickened, opaque nails that are difficult to trim with standard nail clippers
- Brittle, crumbly, or ragged nail edges that break easily
- Separation of the nail from the nail bed (onycholysis)
- Chalky or powdery debris accumulating under or around the nail
- Distortion of the normal nail shape
- Foul odor from the affected nail
- Pain or discomfort when wearing shoes, particularly in advanced cases
If you notice scaling or itching between the toes alongside nail changes, a concurrent athlete’s foot infection is likely — both should be treated simultaneously to prevent reinfection of the nails from the surrounding skin.
Risk Factors for Nail Fungus
Certain factors significantly increase the likelihood of developing onychomycosis:
- Older age — nails grow more slowly and have reduced blood flow with age, making them more vulnerable
- History of athlete’s foot — the same fungus frequently spreads from skin to nail
- Walking barefoot in public wet areas: showers, pools, gyms, and locker rooms
- Wearing tight, non-breathable footwear that creates a warm, moist environment
- Nail trauma — injured nails are more susceptible to fungal entry
- Diabetes or other conditions affecting immunity
- Peripheral arterial disease — reduced circulation to the feet impairs local immune defense
- Sharing footwear, socks, or nail care tools with an infected individual
Nail Fungus Treatment Options in Glendale, AZ
Treatment selection depends on the number of affected nails, severity of infection, patient health status, and patient preference. Our comprehensive treatment options include:
- Prescription topical antifungals: High-penetration nail lacquers such as efinaconazole (Jublia) or tavaborole (Kerydin) are significantly more effective than OTC products, designed to penetrate the nail plate barrier
- Oral antifungal therapy: Systemic medications — primarily terbinafine (Lamisil) or itraconazole — are the most effective treatment for nail fungus, particularly for moderate to severe infections involving multiple nails. Terbinafine is taken for 12 weeks for toenails with high cure rates. Requires periodic lab monitoring for liver safety in some patients.
- Laser nail fungus treatment: FDA-cleared laser devices (such as the Nd:YAG or diode laser) penetrate the nail and generate heat that destroys fungal organisms without harming surrounding tissue. An effective option for patients who prefer non-systemic treatment or cannot tolerate oral antifungals. Multiple sessions are typically needed.
- Nail debridement: Professional trimming and mechanical reduction of infected nail bulk — reduces the fungal load, improves topical drug penetration, and relieves pressure from thickened nails
- Nail avulsion: Temporary or permanent removal of the nail in severe cases to allow direct treatment of the nail bed
- Combination therapy: Oral antifungals combined with topical treatment or laser therapy often achieve superior cure rates compared to any single modality alone
Because nails grow slowly — replacing a toenail fully takes 12 to 18 months — visible results develop gradually even after effective treatment. Our podiatrists provide regular follow-up to monitor progress and confirm cure before discontinuing treatment.
Frequently Asked Questions About Nail Fungus
How is nail fungus definitively diagnosed?
The only way to definitively confirm a fungal nail infection is laboratory testing of a nail clipping or scraping. Options include KOH preparation (immediate in-office microscopy), fungal culture (most specific but takes 4 to 6 weeks), and PCR molecular testing (fastest and most sensitive, identifies the specific fungal species). This confirmation is important because many nail changes mimic fungal infection, and committing to a 3-month course of oral antifungals for a non-fungal nail condition is both ineffective and unnecessary.
Are nail fungus treatments covered by insurance?
Coverage varies significantly. Some insurance plans cover oral antifungals when medically necessary, particularly for patients with diabetes. Prescription topical antifungals may require prior authorization. Laser nail treatment is considered cosmetic by most insurance carriers and is typically not covered. Our office staff can assist with insurance verification, prior authorizations, and provide transparent cost information for all available treatment options.
What is the cure rate for nail fungus treatment?
Oral terbinafine achieves mycological cure (laboratory confirmation of no fungus) in approximately 70 to 80% of patients when taken for the full prescribed course. Clinical cure (visibly clear nail) may take 6 to 12 months after completing medication because of the slow nail growth rate. Laser treatment achieves improvement in 60 to 75% of patients, with multiple sessions enhancing outcomes. Combination approaches typically yield the highest success rates. Our podiatrists set realistic expectations and monitor progress with follow-up evaluations.
Can nail fungus spread to my family members?
Yes. Onychomycosis is contagious through shared surfaces, footwear, towels, and direct skin contact. Family members sharing showers or bathroom floors with an infected person are at elevated risk. During treatment, avoid sharing nail care tools, wear sandals in shared wet areas, and launder socks at high temperatures. Once successfully treated, preventive measures help avoid reintroducing the fungus into the home environment.
How is nail fungus different from nail psoriasis?
Both conditions cause nail discoloration, thickening, and separation from the nail bed, making clinical differentiation challenging. Psoriasis often causes characteristic “oil drop” discoloration, pitting on the nail surface, and nail bed hyperkeratosis. It is typically associated with skin psoriasis elsewhere on the body. Fungal infection is confirmed by laboratory testing, while psoriasis is diagnosed clinically. Since the treatments are entirely different, accurate diagnosis before treatment is essential — applying antifungals to a psoriatic nail for months is both ineffective and costly.
What can I do to prevent nail fungus while in treatment?
During treatment, prevent reinfection of treated nails and spread to unaffected nails by: disinfecting or replacing old shoes (spray with antifungal powder or use UV shoe sanitizers), wearing moisture-wicking socks changed daily, continuing to wear sandals in public wet areas, treating any concurrent athlete’s foot aggressively, keeping nails trimmed and dry, and not sharing nail care tools. These measures also apply after successful treatment to prevent recurrence.
Is it safe to get pedicures when I have nail fungus?
Standard nail salon pedicures are not recommended during active nail fungus treatment for two reasons: risk of spreading the infection to other nails through non-sterilized tools, and risk of spreading to other salon customers. If you choose to get pedicures during treatment, go to a salon that uses sterilized tools or bring your own. Medical pedicures performed in a podiatry setting with proper sterilization are a safe alternative that also provides therapeutic nail debridement.
