What is the active ingredient in Lamisil?

The active ingredient found inside Lamisil is terbinafine HCL; what is terbinafine HCL? Terbinafine hydrochloride (HCL) is an antifungal drug which is metabolized in the liver with a highly variable half-life; it is what makes Lamisil therapeutically effective. It is a drug first discovered in 1991 and has since been listed on the World Health Organization’s List of Essential Medicines; this means it is one of the safest and most effective drugs for the most significant needs within the health system.


What is Terbinafine HCL used for?

Terbinafine HCL is used for antifungal infections; specifically fungal infections affecting nail beds, most commonly the toenails, but sometimes fingernails as well. This condition is called onychomycosis; it is frequently a result of dermatophytes, also called tinea unguium. Dermatophytes are pathogenic fungi that can cause white or yellow discoloration or thickening of the nail or separation of the nail from the nail bed. It may also be used for other fungal infections.


How does Lamisil work?

How Lamisil works to treat onychomycosis is by killing the dermatophytes that cause the infection. Terbinafine inhibits a specific enzyme inside the fungal cell membrane which interferes with cell growth (known as fungal sterol biosynthesis). Inhibition of the enzyme results in a deficiency in ergosterol (a steroid which acts like food or fuel to fungi); this ultimately ends up depriving and killing the fungi (dermatophytes).


How to take Lamisil?

Before starting treatment, ensure you have a clear understanding on how your doctor would like you to take this medication. It is important you follow all directions very carefully. If not restrictions or specific instructions have been set in place; you may take your dose with or without food.

The exact amount of time will vary between each individual.


How can you tell if Lamisil is working?
