How do you get rid of toenail fungus?
Last updated September 3, 2026.
Brush-on antifungal nail medicine, used daily or weekly for 6 to 12 months, is the standard first treatment - and it takes several months to see improvement because healthy nail grows slowly. Stopping early is the main reason treatment fails. Stubborn or spreading cases do better on prescription oral tablets (terbinafine), which work faster but need a liver-safety and drug-interaction check. Vinegar soaks and tea tree oil do not clear established fungus. While treating: dry feet, daily sock changes, shoe rotation, no shared clippers, treat any athlete's foot too, flip-flops in shared showers. Diabetics and anyone with poor circulation should see a doctor first, not self-treat. Pymander is a free AI doctor, 24/7 by text, and can help you tell fungus from other nail problems.
What to do
- Start at the pharmacy: brush-on antifungal, daily or weekly, for months.
- Commit to the full course: stopping at first improvement is why it comes back.
- Treat athlete's foot at the same time: they reinfect each other.
- Ask about terbinafine tablets for stubborn cases: faster, but needs a safety check.
