You can also call 800-222-1222 to reach the American Association of Poison Control Centers or use its online resource if you think you’ve used too much terbinafine. But if you have severe symptoms, call 911 (or your local emergency number) immediately or go to the nearest emergency room.


If you think it is an emergency, call 999 or find your nearest A&E
If you need help now, but it’s not an emergency go to 111.nhs.uk or call 111. Alternatively you can speak to one of our pharmacists or use the Now Patient app to make an appointment with your GP.

What should I do if I miss my dose?

There are occasions when people forget to take their medication at correct prescribed times. This may not only have an effect on potentially making the medication less effective but it may also inadvertently lead to taking doses too close together, thereby increasing the risks of side effects.

Is terbinafine available in the UK on NHS?

Yes, terbinafine is available in the UK with a National Health Service (NHS) prescription. It is prescribed for the treatment of fungal infections, and your healthcare provider can assess your condition and determine if terbinafine is appropriate for you.

Mechanism of action

Terbinafine belongs to a class of medications known as antifungals. It works by inhibiting the growth of fungi, specifically by interfering with the synthesis of ergosterol, a vital component of the fungal cell membrane. By disrupting the integrity of the fungal cell membrane, terbinafine helps to eradicate the fungal infection.

Uses of terbinafine

Terbinafine is primarily used to treat various fungal infections of the skin (tinea cruris), feet (tinea pedis), fingernails, toenails, and scalp (tinea capitis). It is effective against dermatophytes, the fungi responsible for causing common fungal infections such as athlete’s foot and ringworm (tinea corporis). Terbinafine may also be prescribed for fungal nail infections (onychomycosis).

Dosage of terbinafine

The dosage of terbinafine depends on the specific type and severity of the fungal infection. It is important to follow the dosage instructions provided by your healthcare provider. Typically, terbinafine is available in tablet form with a standard dosage of 250 mg. The duration of treatment may vary depending on the type of infection. It is important to complete the full course of treatment as prescribed by your healthcare provider, even if symptoms improve before the treatment is completed.

Forms of terbinafine

Terbinafine is available as terbinafine tablets for oral administration. The tablets are typically available as 250 mg strength.

Contraindications and warnings for terbinafine

Tell your doctor if you have liver disease, any other liver problems, or a weak immune system.

Is it safe to take terbinafine if I am pregnant or planning on becoming pregnant?

It is important to consult your healthcare provider if you are pregnant or planning to become pregnant before taking terbinafine. The safety of terbinafine during pregnancy has not been well established, and the potential risks to the unborn baby should be carefully weighed against the benefits of the medication.

Is terbinafine safe to use while breastfeeding?

Terbinafine can pass into breast milk, and its use during breastfeeding is not recommended without consulting your healthcare provider. They can provide guidance on the potential risks and benefits and help you make an informed decision.

Interactions with other drugs

Terbinafine may interact with certain medications, including certain antifungal agents such as fluconazole or ketoconazole, amiodarone, beta blockers such as atenolol, cimetidine, cyclosporine, monoamine oxidase B inhibitors, rifampin, selective serotonin reuptake inhibitors (SSRIs) such as citalopram, and tricyclic antidepressants such as amitriptyline. It is important to inform your healthcare provider about all the prescription drugs, over the counter nonprescription medications, herbal products, supplements, and vitamins you are taking to avoid potential adverse effects and drug interactions.

Side effects of terbinafine

Common side effects of terbinafine may include gastrointestinal disturbances (such as nausea, diarrhea, stomach pain, loss of appetite, loss of taste, and abdominal pain), tiredness, headache, and skin reactions. Serious side effects are rare but can include liver problems, allergic reactions, and blood disorders. It is important to contact your healthcare provider if you experience any severe or persistent side effects. Get medical help right away if you have any serious side effects such as an allergic reaction.

Promptly report any adverse effects to a healthcare professional for medical advice.
