Antifungal therapy: what works, when, and how to avoid another infection
Fungal infections are common and annoying. Some are easy to treat with creams. Others, like nail fungus, often need pills. This page gives clear, practical advice so you know what to try first, when to see a doctor, and how to cut the chance of coming back.
Topical vs oral: which one should you pick?
For skin infections such as athlete’s foot or ringworm, start with topical antifungals you can buy at a pharmacy—clotrimazole, miconazole, or terbinafine cream. Apply as directed and keep the area dry. Many people see improvement in 1–4 weeks, but keep using the product for the full recommended time so the infection doesn’t return.
Nail infections (onychomycosis) and stubborn yeast problems often respond better to oral drugs. Terbinafine (the active ingredient in Lamisil) is a common choice for nail fungus. Oral treatments usually take much longer to show results: for fingernails treatment might be around 6 weeks, for toenails many people need about 12 weeks. Itraconazole and fluconazole are other options, sometimes used when terbinafine isn’t suitable.
Which to choose depends on where the infection is, how bad it is, your health, and other medicines you take. If you have liver disease, are pregnant, or take certain drugs (like some blood thinners), pills may be risky. Talk to your doctor before starting oral antifungals.
Practical tips to get better and avoid a repeat
Keep the area clean and dry—fungus thrives in moist places. Wear breathable shoes and change socks daily. For athlete’s foot, use shower sandals in public pools and locker rooms. Don’t share nail clippers or towels. When treating ringworm or athlete’s foot, continue the cream for the full course even after symptoms fade.
If you’re trying an oral medicine, expect follow-up. Doctors often check liver function before and during treatment with terbinafine or itraconazole. Watch for side effects like nausea, dark urine, or new yellowing of the skin—these should prompt a call to your provider.
Over-the-counter options work well for many skin infections, but nail fungus and infections in people with diabetes or weak immune systems usually need a doctor’s care. If the infection spreads, becomes painful, or returns after treatment, get evaluated. Sometimes lab testing (a skin scraping or nail sample) helps pick the right drug.
