If you've noticed your toenails turning yellow, thickening, or crumbling at the edges, you're far from alone. Nail fungus — medically known as onychomycosis — is one of the most common nail conditions in the UK, affecting an estimated 3–10% of the population. That's potentially over a million people living with a fungal nail infection right now. Yet many wait months before seeking nail fungus treatment, hoping it will resolve on its own. Spoiler: it rarely does.
The good news is that effective treatments do exist. The challenge is knowing which one is right for your situation — and getting timely expert advice to avoid months of wasted effort on the wrong remedy.
Nail fungus is a fungal infection that affects the nail and the skin underneath it (the nail bed). It most commonly affects toenails, though fingernails can also be involved. The infection is caused by dermatophytes — a group of fungi that thrive in warm, moist environments like gym changing rooms, public swimming pools, and sweaty shoes.
Common signs of a fungal nail infection include:
It's worth noting that not all nail discolouration is fungal. Trauma, psoriasis, and other conditions can cause similar-looking changes. That's why testing before treatment is recommended by NHS guidance — treating the wrong thing wastes time and money.
If you visit your GP with a confirmed fungal nail infection, they will typically consider one of the following prescription treatments:
Oral medications are generally more effective than topical treatments for nail fungus, particularly for toenails. The two most commonly prescribed in the UK are:
These medications can have side effects and interact with other drugs, so your GP will assess your suitability before prescribing. Liver function may need monitoring during longer courses.
For milder or early-stage infections, your GP may recommend a medicated nail lacquer such as amorolfine 5% (available over the counter as well as on prescription). This is painted onto the affected nail weekly and works best when the infection is limited to part of the nail.
Topical treatments alone are often insufficient for established toenail infections, as they struggle to penetrate thick nails deeply enough.
Many people try treating nail fungus themselves before seeing a doctor. While OTC options have their limitations, they can be a reasonable starting point for mild cases.
Common OTC nail fungus treatments available in UK pharmacies:
Important: OTC treatments work best on early, localised infections. If the infection has spread beyond one-third of the nail or involves multiple nails, you're likely to need prescription-strength treatment.
Nail drilling (fenestration), offered by podiatrists, involves making tiny channels in the nail to help topical treatments penetrate more effectively — this can improve results significantly when combined with antifungal lacquers.
One of the most frustrating aspects of nail fungus treatment is the timeline. Even with the most effective treatments:
Nails grow slowly, and the visible result of successful treatment only becomes apparent as the healthy nail grows out. This means patience is essential — and so is starting treatment promptly. The longer an infection goes untreated, the more established it becomes and the harder it is to eradicate.
One important note: laser therapy and light-based treatments are sometimes marketed as alternatives, but according to NHS guidance, these have not shown consistent or reliable benefits and are not NHS-funded. If you're considering them privately, proceed with caution and evidence in hand.
Here's where things get difficult. While most fungal nail infections are managed in primary care, getting an NHS GP appointment quickly enough — and then potentially waiting months for a dermatology referral if the diagnosis is uncertain or the condition is complex — can seriously delay treatment.
Recent data suggests routine dermatology referrals can take an average of 43 weeks in England. For a condition like nail fungus, where early treatment leads to significantly better outcomes, this kind of wait is genuinely problematic.
Many people end up managing their infection with inadequate OTC treatments for years, not because better options don't exist, but because timely specialist guidance isn't easily accessible.
This is exactly the gap that Hebra is designed to fill. Hebra is a skin health triage app that uses AI-powered image analysis to assess your nail or skin condition and connect you directly with a dermatologist — significantly faster than the traditional NHS referral pathway.
Whether you're unsure if your nail discolouration is actually fungal, wondering whether OTC treatment has been working, or need prescription-strength medication recommended, Hebra puts expert dermatology insight within reach — without the 9-month wait.
