Antifungal treatments: what works and what to try first

Fungal infections are common and usually treatable. The right treatment depends on where the infection is (skin, nails, mouth, vagina, or inside the body) and how long it’s been there. This page gives short, useful guidance so you can pick the right option or know when to see a doctor.

Common options you'll see

Topical antifungals are the first stop for skin and mild yeast infections. Creams, sprays, and powders with clotrimazole, miconazole, or terbinafine work well for athlete’s foot, ringworm, and jock itch. Apply as directed and keep the area clean and dry.

For nail fungus or infections that don’t improve with topical creams, doctors usually prescribe oral antifungals. Common pills include terbinafine and itraconazole. Fluconazole is often used for yeast infections and some systemic cases, but it’s not ideal for all fungi. Newer or less common options like isavuconazole exist for serious infections—those are handled by specialists.

For oral thrush or vaginal yeast infections, you’ll find both topical (troches, creams) and oral options (single or short-course tablets). Match the form to convenience and severity: single-dose oral fluconazole can work well for many vaginal yeast cases, while persistent or recurrent infections may need a different approach.

Practical tips to use antifungals the right way

Follow the full course. Stopping early is a main reason infections come back. If a cream says 2–4 weeks, finish it even if the rash looks gone after a few days.

Watch for side effects. Topical medicines may sting or irritate. Oral antifungals can affect the liver and interact with other drugs (statins, warfarin, some antidepressants). Tell your doctor about all medicines you take.

Pregnancy and breastfeeding matter. Many oral azoles are not safe during pregnancy. If you’re pregnant, ask a clinician before taking pills; topical options may be safer in some cases.

Prevent recurrence. Keep feet dry, change socks daily, avoid tight shoes, and dry the groin area after showers. For vaginal yeast, avoid scented products and wear breathable cotton underwear. Nail fungus is slow to treat—trim nails, use antifungal nail varnishes if advised, and be patient.

Antifungal resistance exists. Don’t use antifungals you don’t need. If an infection fails standard treatments, see a doctor for testing so the right drug is chosen.

When to see a doctor: if the infection spreads, causes fever, affects large skin areas, involves nails or scalp, or if you have diabetes or a weakened immune system. Those situations need prescription therapy or a specialist.
