What is Lamisil Spray (Terbinafine) prescribed for?

Fungal infections are a common occurrence throughout the natural world. And within humans a fungal infection can occur when an invading fungus takes over an area of the body and becomes too much for the immune system to handle. Fungus can live in anything, the air, soil, water, and in plants, as well as humans. And when in humans, in can lead to skin problems like rashes and bumps.

Terbinafine, the active ingredient in Lamisil Spray, is used to treat various types of fungus, such as ringworm, athlete’s foot, and jock itch. This medication is also used to treat a skin condition known as pityriasis, which is a fungal infection that causes the lightening and darkening of the skin of the neck, chest, arms and legs. This medicine is what is known as an antifungal. Taking this medication will ultimately stop the growth of the fungus.

What is in Lamisil?

Lamisil spray is made up of a drug called 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 spray therapeutically effective. It was 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 used for?

Lamisil spray (terbinafine) is used for the treatment of fungal infections; specifically tinea fungal infections. Tinea is a group of fungal infections caused by dermatophytes; dermatophytes are pathogenic fungi that are spread through direct contact from other people, animals, and soil, as well as indirectly from objects and materials. Within this group of fungal infections includes tinea pedis (athlete’s foot), tinea cruris (jock itch), and tinea corporis (ringworm). Additionally, Lamisil spray may also be used for tinea versicolor, which, despite its name, is not caused by dermatophytes, but by natural yeast found in human skin (a type of fungi); due to this, the condition is more commonly referred to as pityriasis versicolor to prevent it from being associated as a tinea. All of these infections are associated with an itch and may include redness and irritation.


How does Terbinafine work?

Terbinafine works 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, as they need it to survive); this ultimately ends up depriving and killing the fungi (dermatophytes).


How to use Lamisil Spray?

To use Lamisil spray, first ensure you have cleaned and thoroughly dried the affected area. Next, hold the bottle completely upright or completely downwards; spray a sufficient amount to cover the entire affected area and any surrounding skin. This form of Lamisil contains alcohol; for this reason, it is important not to use it on your face. Your doctor will let you know how many times to use the medication and how long to use it for. The typical dosing regimen for ringworm or jock itch is once per day; and twice per day for athlete’s foot or tinea versicolor. For all indications, treatment is commonly done over a 7 day period (1 week).


How long does it take for Lamisil to work?

It is suggested that you should find relief from symptoms within a couple days of starting treatment; irregular or improper use may affect the efficiency of the medication. If no signs of improvement show within 2 weeks of proper use, you may want to consider consulting your doctor as this medication may not be right for you.


How long does Lamisil stay in your system once finished?

The exact amount of time it takes to clear the system will vary between each individual. Since the drug distributes into the skin and adipose tissue, it remains in the body for a long time, but the effectiveness will not remain for the full duration. The effective half-life of the spray is about 17-36 hours; it will continue having therapeutic effects for about 5 half-lives; up to about 180 hours (7.5 days). However, the drug will remain in your body for up to approximately 2000 hours (83 days), with a half-life of 200-400 hours.

How safe is Lamisil?

Lamisil Spray is a safe medication to use; the topical forms of terbinafine are low-strength, only containing 1% of the drug and is available over-the-counter. You may experience certain side effects, like dryness of the skin or temporary burning during application; however these side effects are normal and are not considered dangerous. Other than side effects, there are very little – if any – risks associated with topical Lamisil. Additionally, as previously mentioned, you can find terbinafine on the World Health Organization’s List of Essential Medicines; this ensures that it is a safe medication when used properly.


What to do if Lamisil doesn't work?

If you’ve been using Lamisil with no success in improvement, you may be able to speak with your doctor about alternate medications. If the spray doesn’t help, you could consult your doctor about switching to the tablet form of Lamisil; it is a stronger medication compared to the topical form of Lamisil. If you are interested in switching to a completely different brand (or generic) medication; you may want to consider a topical antifungal medication like Lotriderm Cream (clotrimazole/betamethasone) or if you prefer tablets, an antifungal tablet such as ketoconazole tablets. We carry all of these suggested medications at My Drug Center.


How much does Lamisil cost?

Lamisil Spray, at My Drug Center, is available in two different quantities and prices. A 30ml bottle is $32.00; or a 90ml bottle for $42.00. This medication does not require a prescription to order.


How long after taking Terbinafine can I drink alcohol?

Alcohol and terbinafine are both metabolized in the liver and therefore the combination should be avoided to decrease the risk of complications. You should wait until terbinafine completely clears the system before consuming alcohol. Consult your doctor for a specific time period on how long to wait before consuming alcohol; you should follow the medical advice given to you by your doctor, only.


What are the side effects of Terbinafine?

Some side effects of terbinafine (Lamisil spray) may include diarrhea or upset stomach; these are the more common side effects. You may also experience acid or sour stomach, belching, or change or loss of taste; these side effects are less common. The listed side effects should not alarm you; other side effects not listed here may also occur. Speak with your doctor if side effects become unmanageable or do not go away.


How long do Terbinafine side effects last?

Side effects will generally stay present while your body adjusts to the new medication; therefore, the duration of side effects has a vast variety. Some may experience side effects for close to the entirety of treatment where other patient’s side effects disappear shortly after starting. Other patients may not even experience any side effects at all. If side effects persist and become unmanageable, consult your doctor.
