Terbinafine tablets

Terbinafine is a treatment for fungal infections that’s available in the form of tablets or as a cream. Which type is more likely to be used by patients (and how long the treatment is used for) depends on the exact type of fungal infection that is being dealt with.

Whichever type is used, terbinafine contains an active ingredient of the same name that eliminates fungi by preventing it from multiplying before attacking its cells. Conditions that terbinafine can be used for include athlete’s foot, ringworm, jock itch and fungal nail infections.

What is Terbinafine?

Terbinafine is an antifungal medication used to treat athlete’s foot and other fungal-related infections. Terbinafine is available as tablets and as a cream. The tablet version is popularly used for treating fungal nail infections, while the cream can be used against jock itch and ringworm as well as athlete’s foot.

How does Terbinafine work?

Terbinafine is the active ingredient in the medication of the same name. It combats fungal infections by limiting the production of ergosterol, a component which fungi uses to multiply. Without ergosterol, holes begin to form in the fungal cell structure and this lets the body’s healthy bacteria infiltrate the unwanted cells and kill them off.

How is Terbinafine taken?

When opting for tablets, Terbinafine can be prescribed in two ways, as either a continuous course or as pulsed therapy. The dose you are prescribed will depend on the type of infection and how bad it is.

When following a daily course, a tablet is usually taken once a day, swallowed whole with a glass of water. Under pulsed therapy, patients take two tablets at once daily for seven days, followed by 21 days off. The same pattern is repeated in the following two months. The tablets can be taken with or without food.

If you’re using the cream version of terbinafine, it can be applied one or two times daily. The recommended duration and frequency of treatment will depend on the type and area of infection. For instance, treatment for athlete’s foot will typically last one week, while for jock itch it could last one or two weeks. Some skin infections may require up to 6 weeks of treatment, while nail infection treatment could take anywhere between 6 weeks and 3 months and toenail infections may need up to 6 months’ treatment.

What are the side effects of Terbinafine?

Various side effects have been reported by users of terbinafine, although not everyone gets them. The most common side effects associated with terbinafine tablets include the following:

  • Loss of appetite
  • Stomach ache or feeling of fullness
  • Joint and muscle pain
  • Rash, reddening of skin with itching and hives (urticaria)
  • Headache

With terbinafine cream, the most likely side effect that occur is that skin may become itchy or peel. Other changes and irritations to the skin are possible but rarely occur.

Can I use Terbinafine?

You should avoid using terbinafine if you are allergic to any of the ingredients included in the medicine or if you have a severe kidney or liver problem. You should consult your doctor about whether terbinafine is right to you if any of the following conditions apply to you:

  • You’ve had liver or kidney problems in the past
  • You have psoriasis (a skin disease with raised red patches of skin covered with silvery scales)
  • You have systemic lupus erythematosus (inflammation to the joints, skin and other organs)
  • You’ve developed severe reduction in the number of white blood cells (agranulocytosis) or an illness with blistering of the skin

Other medications can potentially cause complications if taking at the same time as terbinafine, so consult your doctor or pharmacist if there’s anything else you are currently taking. If you plan to take terbinafine tablets, then these medicines are particularly worth mentioning if you are currently taking or recently taken any of them:

  • An antibiotic called rifampicin
  • Cimetidine (treats stomach ulcers and heartburn)
  • Antidepressants including tricyclic antidepressants, SSRIs (selective serotonin reuptake inhibitors), or MAOIs (monoamine oxidase inhibitors)
  • Beta-blockers, anti-arrhythmics and other medicines for heart problems
  • Oral contraceptives (the pill)
  • Ciclosporin (treats skin conditions or prevents rejection of organs or tissues following a transplant)
  • Tolbutamide (treats diabetes)
  • Triazolam (treats anxiety and/or trouble sleeping)
  • Terfenadine (treats hay fever or other allergies)
  • Other medicines that treat fungal infections

If you are pregnant, breast-feeding or you think you may be pregnant, then you should not take terbinafine in either tablet or cream form, unless your doctor instructs you to. It is possible that terbinafine can pass into breast milk.

What if I take too much Terbinafine?

If you take more Terbinafine tablets than you are supposed to then you should get in touch with your doctor or your nearest hospital casualty department as soon as possible. It is possible you may feel dizzy, sick and get headaches or stomach pains as side effects.

If you’re using the cream and apply more than a thin layer of it, then remove some of the cream. If you accidentally get the cream in your eyes or swallow some then you should rinse any cream in the eyes with running water and contact your doctor immediately. The side effects of ingesting this cream are similar to the ones you can get from taking too many Terbinafine tablets.

What if I forget to take Terbinafine?

If you forget to take Terbinafine when due, then do so when you remember. However, do not take a double dose (or apply extra cream) to make up for a forgotten one. You should use terbinafine for the full duration of your treatment. Don’t stop the treatment early without consulting your doctor first, even if the infection heals. If you stop the treatment early, then a fungal infection can return.
