More information about Terbinafine

What is Terbinafine?

Terbinafine is a medicine used to treat fungal infections of the skin and nails. It is available under the brand name Lamisil.

Terbinafine is available as tablets, cream, gel and a spray. At HealthExpress, our doctors are able to prescribe Terbinafine tablets once you have completed a consultation for fungal nail infections. You will also need to complete a liver function test during your treatment, this will be included with your order.

How does Terbinafine work?

Terbinafine is an antifungal medication. It works by stopping the growth of fungi by disrupting their cell membrane production. It does this by blocking the synthesis of ergosterol, an important component of the fungal cell membrane. This leads to holes forming in the cell membrane ultimately leading to death of the fungus and resolution of the infection.

What are the benefits of Terbinafine?

Terbinafine has many benefits when used to treat fungal infections.

  • Kills fungi - This medicine kills fungi, rather than just stopping its growth.
  • Convenient - The tablets are easy to take and allow for systemic treatment. This is also beneficial for widespread infections which topical treatments may not address.
  • Broad-spectrum antifungal - Terbinafine is effective against a range of fungi, making it a good choice for treating various types of fungal infections.
  • Improves the appearance of nails - By treating the infection, it restores the healthy appearance of nails in up to 12 weeks.
  • Reduces discomfort - By killing the fungi, this medicine improves symptoms such as itching, flaking and nail discoloration,

How effective is Terbinafine?

Research suggests that Terbinafine is effective for treating fungal nail infections.

In one study, 120 patients with toenail onychomycosis (fungal infection of the toenails) were instructed to take Terbinafine 250 mg tablets once daily for up to 24 weeks.

The results showed that Terbinafine completely cured fungal toenail infections in 67% of patients who were treated for 6 weeks, 82% who were treated for 12 weeks, and 85% who were treated for 24 weeks. The study also concluded that a treatment period of 12 weeks was sufficient for fungal toenail infections.

Who can and cannot take Terbinafine?

Who can take it?

Terbinafine can be taken by most adults with fungal nail infections. However, you must always tell our doctors about other medical conditions you have or any other medications you take.

Who cannot take it?

Do not take Terbinafine if you are allergic to it or any of the other inactive ingredients in this medicine. You should also avoid taking this medicine if you have any severe liver or kidney impairment.

Speak to your doctor before taking this medicine if you have:

  • liver or kidney problems
  • psoriasis (a skin disease)
  • any blood disorders
  • cutaneous and systemic lupus erythematosus (skin disorders)

If you are not sure whether any of these factors apply to you, consult a healthcare professional before taking Terbinafine.

What is a liver function test?

A liver function test (LFT) assesses a patient’s liver health by measuring the levels of specific enzymes and proteins in the blood. This test can help detect and monitor inflammation, infection and diseases of the liver.

At HealthExpress, we provide a LFT kit along with your Terbinafine tablets. This is a finger prick blood sample kit. Once you have completed the test, your sample is sent to a third-party laboratory for analysis.

The LFT analyses your total protein, albumin, globulin, alanine transferase (ALT), alkaline phosphatase (ALP), aspartate transferase (AST), gamma GT and bilirubin.

Why is a liver function test needed?

All patients must complete a liver function test with their first prescription (within the first week), then every 4–6 weeks during treatment. In rare cases, Terbinafine can cause liver damage or failure, even in patients without pre-existing liver conditions.

At HealthExpress, our liver function test kits come with everything you need to collect the sample at home.

How do I complete the liver function test?

The LFT kit provided with your Terbinafine tablets, is a finger-prick blood sample kit. This kit includes everything needed to collect your blood sample, package it securely and return it to our third-party laboratory, free of charge.

Please note: If you make a mistake collecting your sample, you will need to purchase a replacement kit. Please contact our customer service team to arrange this.

How do I take Terbinafine?

To take this medicine correctly, follow the dosage and treatment course our prescribers recommend.

To ensure this medication is effective, follow the instructions below:

  • Take one tablet once daily.
  • Take each tablet with plenty of water.
  • Swallow the tablet whole, do not break, chew or split tablets as this can affect the way the medicine works.
  • The tablets can be taken with or without food.

What dose should I take?

At HealthExpress, Terbinafine is available as 250 mg tablets. The recommended dose to treat fungal nail infections is one 250 mg tablet taken once daily. However, if you suffer from kidney problems or other medical conditions, your doctor may alter your dose.

When do I take it?

You should start taking Terbinafine as soon as you notice symptoms. This medicine is taken once daily, preferably at the same time each day. You can take it in the morning or at night.

How long do I take it for?

Fungal nail infections can take a long time to treat. This is because it takes time for your new healthy nails to grow out and replace the infected nails. Your doctor will tell you how long your treatment with Terbinafine will last.

Treating nail infections usually takes between 6 weeks to 3 months, however, toenail infections often take up to 6 months or more. Even after the infection is cured, it might take a few weeks for symptoms such as discolouration or thickened nails to completely resolve.

What happens if I miss a dose?

If you forget to take a dose, take the missed dose as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and take your next dose at your usual time.

How long does it take for Terbinafine to work?

Terbinafine starts to work as soon as you start taking the tablets. After taking a tablet, the medicine is well absorbed and the mean peak plasma concentration is reached within 1.5 hours of taking the dose.

Fungal nail infections typically take several months to resolve. You must keep taking it exactly as prescribed to ensure the infection is fully treated.

What should I do while taking Terbinafine?

Here are some things you can do to prevent fungal nail infections:

Do’s Don’ts
  • Keep your feet clean and dry
  • Wear slippers in communal areas
  • Change your socks daily and whenever they get sweaty
  • Alternate footwear and let closed shoes air out for 24 hours before wearing them again.
  • Moisturise dry skin to avoid cracks
  • Don't wear closed footwear for long periods of time
  • Don’t walk around barefoot in communal places like showers, locker rooms and gyms
  • Don’t share footwear like shoes and socks, or personal items like towels and toenail clippers

Fungal nail infections are also more common among those who have a weakened immune system or other health conditions, like diabetes, psoriasis or peripheral arterial disease. To prevent this, it’s important to address poorly controlled diabetes and stay on top of your treatment for other health conditions.

Terbinafine FAQs

Can I wear nail polish during Terbinafine treatment?

You should check with your healthcare provider before applying nail polish while you have a fungal nail infection. This is because nail polish can trap moisture in your nails, which can worsen fungal nail infections.

Can I stop taking this medicine once my symptoms improve?

No, it is important that you complete the entire course of treatment prescribed by your doctor, even if your symptoms improve early. Stopping too soon can lead to the infection returning or not being properly treated.

When do I need to take the liver function test?

You must take the LFT in week 1 of each 6-week course of Terbinafine tablets. Once we receive your test results from our third-party laboratory, our clinical team will advise you on the next steps of treatment.

You must have completed a LFT and received a normal result before continuing with your next 6-week course of Terbinafine treatment.

How long will it take to get my test results?

Once we receive your test results from the lab, our clinical team will review the report within 1 to 2 working days.

How will I receive my test results?

You will receive an email and SMS to inform you that your test has been completed. You can then log in to your Member’s Area to view your results.

What happens if my test results are abnormal?

If your test results are abnormal you will receive a notification in your Member’s Area advising you on next steps. You must have a normal liver function test result to continue treatment and before you can purchase any further courses of Terbinafine.

What happens if my sample fails and is rejected by the lab?

If you follow the kit instructions and watch our instructional video, your sample should not fail. Some reasons why a sample might fail may include the following:

  • Unlabelled – you did not complete and attach the sample tube label.
  • No form – you did not include the completed lab form with your sample.
  • No sample – you did not provide the sample requested.
  • Insufficient – you did not fill the blood collection tube to the fill line.
  • Leaked – you did not package your sample correctly.
  • Too old – you did not post your sample as soon as possible.

If your sample is rejected for any of the above reasons, you will need to purchase another test.

If your LFT sample is haemolysed (or clotted), you can take one free re-test only.

Please note this will only be granted on a single occasion, not with each purchase or course of Terbinafine. Refer to our Terms and Conditions for additional information regarding failed samples and retesting.
