Terbinafine Tablets FAQs

What is Terbinafine?

Terbinafine 250mg are antifungal tablets used to treat fungal skin and nail infections. Common forms of these infections include tinea corporis (ringworm), tinea pedis (athlete's foot), tinea cruris (fungal infection of the groin, e.g. jock itch) or fungal nail infections.

Typically, you should treat fungal infections with topical creams, sprays or powders. However, for more severe infections, oral tablets may be required.

You may also consider using antifungal tablets such as Terbinafine 250mg if the infection is widespread or in a place that's difficult to treat with creams or gels.

This medicine contains the active ingredient terbinafine hydrochloride.

How does Terbinafine work?

A fungal infection is typically, but not always, caused by fungi from the dermatophytes group growing and multiplying rapidly in one area.

Fungi thrive in wet, hot, dark places which is why many infections occur on the feet and in the groin area.

Terbinafine is an antifungal medicine that kills the fungi that causes these infections by forcing holes into the fungal cell membranes.

These cell membranes are vital to the fungi's existence. They keep unwanted substances out and stop the contents of the cell leaking. By causing holes to appear, the terbinafine kills the fungi and clears the infection.

The length of treatment depends on the infection. Skin infections may take 2-6 weeks to treat and nail infections can take 6-12 weeks.

Treatment times may also be extended in the case of severe infections. Infected toenails may require treatment for 6 months or more.

If after 2 weeks of treatment there are no signs of improvement, you should speak to your doctor about alternative treatments.

How do I use Terbinafine?

  • Take a tablet from the blister pack
  • Swallow the tablet with a drink of water
  • This medicine can be taken with or without food
  • Repeat as directed in the accompanying leaflet or by your doctor
  • If you forget to take a dose, take it as soon as you remember. You can then take the next tablet at the usual time. However, do not take two tablets at once to make up for a missed dose.
  • You should try to take these tablets at the same time each day for best results

What dosages are available for Terbinafine?

Terbinafine 250mg only comes as one dose (250mg) and is available in blister packs of 14 or 18 tablets. The normal dose for adults is one Terbinafine 250mg tablet per day.

What are the side effects of Terbinafine?

Medicines affect people differently and you may not experience side effects while taking Terbinafine 250mg.

However, it is very common for people taking these tablets to experience a decrease in appetite and disturbances in the gut. This could include: indigestion; nausea; bloating, vomiting; diarrhoea; or, abdominal pain. You could also experience: a rash; hives; or, pain in the joints and muscles.

It is also common for people taking Terbinafine 250mg to experience headache.

Some individuals have reported that their sense of taste has been altered by taking these tablets. This can result in a loss of taste entirely during the treatment, but this usually returns a few weeks after the course of treatment is complete.

In rare cases, you may experience dizziness; pins and needles; liver problems; and, reduced sensation or numbness.

In extremely rare cases, you may experience decreased levels of white blood cells or platelets; a spinning sensation; hair loss; photosensitivity; and, serious skin reactions including blisters and peeling.

You must contact your doctor if you experience any rare or extremely rare side effects.

You should also be aware that Terbinafine 250mg can cause liver problems. Seek medical advice if you experience unexplained itching or fatigue; jaundice (where your skin or eyes turn yellow); dark urine or pale stools; nausea and vomiting; pain in the upper right abdomen; or, a loss of appetite.

Speak to your doctor if you have an allergic or skin reaction to the tablets, a fever or sore throat.

What precautions should I take when using Terbinafine?

You must exercise caution when taking Terbinafine 250mg if you have kidney or liver problems and it might be best to lower the dose in this case. If you have psoriasis this medication can exacerbate the symptoms, so you may wish to find an alternative treatment.

If you have a long-term autoimmune disease, such as systemic lupus erythematosus (SLE), it may be best to look for an alternative medicine.

Ask your doctor or pharmacist for advice about taking Terbinafine 250mg alongside these medications:

  • cimetidine
  • fluconazole
  • amitriptyline, nortriptyline, imipramine and other tricyclic antidepressants
  • amiodarone, beta blockers and other heart medicines
  • ciclosporin
  • atomoxetine
  • SSRI antidepressants including paroxetine
  • tolbutamide
  • terfenadine
  • triazolam
  • tamsulosin

If you take rifampicin, you may require a larger than normal dose of terbinafine as this antibiotic can decrease the blood level of terbinafine and therefore its effectiveness.

Taking oral contraceptives and Terbinafine 250mg can cause break-through bleeding and irregular periods.

Ask your doctor or pharmacist for advice about possible interactions with other medications, including over-the-counter medicines and herbal remedies to avoid any adverse interactions.

Terbinafine 250mg tablets are not suitable for women who are breastfeeding or pregnant.

This medicine is not suitable for use in children, individuals with active or long-term liver disease, or those who are allergic to any of its ingredients.

You must take Terbinafine 250mg tablets regularly, as directed by your doctor, and complete the entire course even if your symptoms seem to have cleared. If you don't, the fungal infection may return and take longer to treat.

If you experience an allergic reaction after taking Terbinafine 250mg tablets, inform your doctor or pharmacist immediately.
