Fungal nail infections, also known as onychomycosis, are often found in the toenails but can also affect the fingernails. They tend to be more common in adults over 55, but they can affect people of all ages.

The condition can arise due to numerous reasons, however it is frequently linked to the skin infection known as athlete’s foot. This affects the skin on the feet surrounding the nails and in between the toes, creating an itchy and scaly area. If left untreated the microspores can begin to attack the nail bed and spread the infection to the nails. The majority of fungal nail infections are caused by a particular type of fungi called dermatophytes, but they can also be caused by Candida.

People with diabetes, psoriasis, poor circulation or a weakened immune system may be more susceptible to fungal nail infections. Those who have to wash their hands regularly, live in a humid climate or smoke can also be more likely to become infected. Once infected, the nails can become thickened and discoloured, turning a yellow, green, white or black colour. Left untreated, further symptoms may develop, such as the nail becoming damaged or dislodged from the bed.

Fungal nail infections can be easily treated with antifungal medication. 

Taken as a tablet, terbinafine attacks the infection through the bloodstream. The active ingredient terbinafine disrupts the fungal cells production of ergosterol, which it requires to multiply. Once this nutrient is no longer in supply, the stability of the fungal cells become compromised, and they eventually perish.

Continuous therapy (taken every day for a certain period) is the conventional mode of treatment for fungal nails infections. However, clinical trials have shown that terbinafine can also be effective when taken as ‘pulsed therapy’. This method of administration is prescribed off-label. You can read more about off-label prescribing here.

Terbinafine is the active component in Lamisil, but is also available in generic form. 

Loceryl is a type of nail lacquer. The active ingredient in this topically-applied medication is amorolfine. This is an antifungal, which again prevents the offending fungi from producing ergosterol, and in doing so works to diminish the fungal cell structure.

Trosyl, a nail solution containing tioconazole, is topically administered to the infection site too, and performs a similar function.

You can order fungal nail treatment online by using our simple consultation service. Our pharmacy prescribers and GMC doctors are available to review your case. Once approved, your prescription will be safely and securely dispensed from our UK-based pharmacy. You can then expect to receive your treatment within one working day.

Types of Treatment

Types of Treatment

Nail infections are caused by excessive amounts of fungi that invade the nail bed. If left untreated the infection can spread to other nails.

Trosyl is a nail solution. It contains an antifungal called tioconazole, which is applied topically and neutralises the infection.

Loceryl is a nail lacquer, which contains amorolfine, and is also a topically administered antifungal agent.

Lamisil and Terbinafine tablets contain antifungal ingredients that are directed through the bloodstream to fight the infection at the source.

Both tablets contain the same ingredient, terbinafine. Lamisil is the branded version; whereas terbinafine is the licensed generic. This oral medication may be prescribed as a continuous treatment or ‘off-label’ as pulsed therapy. You can read more about off-label prescribing here.

How do they work?

Fungal nail infections are caused by an upset in the number of fungi found on the skin. This can be brought on by various factors, including: skin infections such as athlete’s foot; persistent exposure to warm and damp conditions; diabetes; damage to the nail; or a weakened immune system. 

Antifungal treatments dispel the infection by killing off the fungi. They do this by compromising the structure of the fungal cell membrane.

What are the side effects?

Everyone can react differently to medicines, so it is important to pay attention to the potential side effects so that you can seek medical attention if required. The most common side effects include diarrhoea, indigestion, nausea, stomach pain and headaches. This list is not exhaustive. For more information you should consult the respective patient information leaflet.

Can I take them with other medications?

These products can interact with others so it is important that you disclose any other treatment that you are taking to our prescriber.

Question and Answers

What’s the difference between the medications?

The antifungal medication for fungal nail infections tend to work in similar ways.

Whereas Lamisil and Terbinafine are different versions of the same tablet, and are taken orally, Loceryl and Trosyl are applied directly to the infection site.

Should I use Loceryl, Trosyl, Terbinafine or Lamisil?

It depends on a number of factors, including your medical profile, and whether you are currently using other treatments. For more information, refer to the respective product pages.

Are there different side effects?

Yes. Some antifungal medications can cause diarrhoea, indigestion, nausea, stomach pains and headaches. Most side effects are a mild inconvenience whilst your body gets used to the medication but occasionally there can be serious reactions. Therefore it is important to read the provided patient information leaflet for a comprehensive list.
