Antifungal Medication
Support for advanced fungal nail infections with treatment that works from within the body.
Oral Antifungal Medication may be recommended for more advanced fungal nail infections, particularly when the infection affects a large part of the nail or involves the nail root. Unlike topical treatments that work on the nail surface, oral antifungal medication works through the bloodstream to help target the infection from within.
This treatment may help reduce fungal growth and support clearer, healthier nail growth over time. Because oral antifungal medication can interact with other medicines and may not be suitable for every patient, it must be prescribed by your GP after considering your medical history.
What oral medications are available?
In New Zealand, the oral antifungal medications most commonly prescribed by GPs include:
Lamisil (terbinafine)
Sporanox (itraconazole)
Other medications may also be prescribed depending on your medical history, current medications, and your GP’s clinical judgement.
How do I get diagnosed?
Your diagnosis begins with a consultation and fungal nail assessment.
Your clinician will:
take a detailed medical history
review your risk factors
examine the affected nails
use fungal nail testing to help confirm the diagnosis
This may involve taking a clipping of the affected nail, photographing the infected nails, and measuring the line of fungal growth from the base of the nail so your progress can be monitored over time.
Once the diagnosis is confirmed, your clinician will explain the most appropriate treatment pathway and answer any questions you may have.
Who should use oral antifungal medication?
Oral antifungal medication is not usually recommended as a first treatment option for infections affecting less than 50% of the nail.
However, when fungal nail infection affects more than 50% of the nail or involves the nail root, oral antifungal medication may be considered as part of a treatment plan.
Because these medications work through the body, they may interact with other medicines and may not be suitable for some patients. They can also place strain on the liver, which is why the decision to prescribe oral antifungal medication must be made by your GP after reviewing your medical history and any relevant risks.
What is involved in the oral antifungal medication process?
If oral antifungal medication is considered appropriate, it will need to be prescribed by your GP.
Before you begin treatment, your clinician may trim, thin, and debride the affected nails to remove as much damaged fungal nail material as possible. You will also receive hygiene and prevention advice to help reduce the risk of reinfection during and after treatment.
In many cases, combination treatment may be recommended to improve overall results. This can include topical treatment, laser treatment, or other podiatry care depending on the severity of the infection and your treatment goals.
Patients using oral antifungal medication as a standalone treatment are often advised to return for regular review appointments. In many cases, follow-up may continue for up to 12 months so nail progress can be monitored properly.
If you are having a combination of treatments, your clinician may recommend more frequent follow-up.
Do I need to do anything with my nails during treatment?
A combined treatment approach is often recommended to help improve treatment outcomes.
This may involve using a topical antifungal lacquer alongside oral antifungal medication, as combination treatment can help improve fungal nail clearance in more advanced cases.
In many cases, Rejuvenail may be recommended as part of the treatment plan while you are taking oral antifungal medication.
At around the 3-month review, your clinician may also assess whether another treatment option, such as cold laser treatment or total nail avulsion, may help support your progress.
