Buy Terbinafine for Fungal Nail Infections

Terbinafine will not work if your nail condition is not caused by a fungus. Available as generic Terbinafine tablets or under the brand name Lamisil - both have the same active ingredient terbinafine hydrochloride. Patients are required to have a finger prick blood test to check their liver function after 4 weeks of treatment. Finger prick test is included with your order and is simple to perform at home.

Please Note

All medication can cause side effects. We have only listed a few to be aware of. Details of all side effects, including rare side effects to be aware of, are listed in the patient information leaflet (PIL). When completing your medical questionnaire, it is very important that you answer the questions truthfully. This is to ensure your doctor has a full picture of your medical history before prescribing. List all medicines you are already taking, including non-prescription and herbal medicines.


There are many non-prescription and prescription only topical preparations available, but toenail fungus is very hard to eradicate using creams and lotions. The fungal spores grow under an infected nail which makes it extremely difficult to treat as topically applied medicines cannot penetrate or get under the nail easily.

Looking after your medicine

Do not take medicines after the expiry date stamped on the pack. Keep all medicines out of the reach and sight of children.

Medicines are only intended to be used by the person they are prescribed for. Do not give your prescribed medicine to anybody else, even if they have the same symptoms as you. Medicines can be harmful if used by anybody other than the person they have been prescribed for.

Terbinafine hydrochloride is the name of the drug found in Terbinafine fungal nail tablets, also known under the brand name Lamisil. This medicine is used to treat fungal nail infections and can be used for both fingernail and toenail infections. When taken orally as tablets, Terbinafine can be very effective at treating fungal nail infections. It is typically much faster at treating fungal nail than topical solutions and creams that may be available over the counter.

Terbinafine fungal nail tablets are a prescription only medication which means that they have to be prescribed by a doctor. You can however get Terbinafine prescribed online after completing a full doctor consultation. Whilst over the counter products are available to treat fungal nail, they are usually a lot less effective and typically take much longer to treat the problem – often up to a year. There are some Terbinafine creams available over the counter, but they contain a much smaller amount of the active ingredient terbinafine hydrochloride and are mainly used for fungal skin infections.

Terbinafine tablets can affect the way your skin reacts to sunlight and can make you burn much more easily. It is therefore advised to avoid sun exposure (especially tanning beds) whilst taking Terbinafine. It is also advised to limit alcohol and caffeine intake whilst taking Terbinafine tablets. Always read the patient information leaflet for a full list of precautions and side effects before taking your medicine.
