Frequently asked questions

What is Lamisil At used for?+
Lamisil At is a topical antifungal medication containing terbinafine hydrochloride, indicated for the treatment of dermatophyte infections of the skin such as athlete's foot (tinea pedis), ringworm (tinea corporis), and jock itch (tinea cruris). It works by eliminating the fungus that causes these conditions, helping to relieve symptoms and clear lesions.
How does terbinafine work?+
Terbinafine inhibits the fungal enzyme squalene epoxidase, a key step in the biosynthesis of ergosterol, an essential component of fungal cell membranes. By blocking this pathway, the drug causes accumulation of toxic squalene and depletion of ergosterol, leading to fungal cell death and resolution of the infection.
What is the usual dose?+
The specific dosage and duration of Lamisil At are determined by the prescribing healthcare professional based on the type and severity of the infection, the area of skin involved, and patient factors. The prescriber will provide instructions on how much product to apply, how often, and for how many days.
Is it safe in pregnancy or breastfeeding?+
Safety data for topical terbinafine during pregnancy and lactation are limited. It should only be used if the potential benefit outweighs any possible risk to the fetus or infant, and only under the guidance of a qualified healthcare provider. Women who are pregnant, planning pregnancy, or breastfeeding should discuss alternatives with their clinician.
How do I order Lamisil At from GNH USA?+
To place an order, submit an enquiry on the product page at gnh-usa.com, specifying the required quantity. GNH USA works with hospitals, pharmacies, and procurement teams worldwide, and will request verification of trade or institutional credentials. After confirmation, the team provides pricing, availability, shipping details, and assists with any necessary import documentation.
How does Lamisil At compare with other antifungal classes?+
Lamisil At (terbinafine) belongs to the allylamine class, which acts by inhibiting squalene epoxidase, whereas azole antifungals block lanosterol 14α‑demethylase. Allylamines often achieve faster fungal clearance and are effective against dermatophytes, while azoles have a broader spectrum but may require longer treatment. Choice depends on infection type, patient tolerance, and physician preference.
How should Lamisil At be stored?+
Lamisil At should be stored at room temperature, below 25 °C, in its original packaging. Keep the container tightly closed, protect it from moisture, direct sunlight, and excessive heat. Do not freeze the product, and keep it out of reach of children.
How is Lamisil At applied?+
The medication is applied topically to the affected skin area. Clean and dry the skin, then spread a thin layer of the cream or gel over the lesion and a small margin of surrounding healthy skin, usually once or twice daily as directed by the prescriber. Wash hands after application unless treating the hands.
What are the most serious risks to watch for?+
Although rare, serious adverse reactions can occur, including severe allergic responses such as angioedema, widespread skin blistering, or systemic effects like liver enzyme elevation. If any signs of swelling, difficulty breathing, extensive rash, or jaundice develop, discontinue use immediately and seek medical attention.
Who should not use Lamisil At?+
Individuals with a known hypersensitivity to terbinafine or any component of the formulation should avoid using Lamisil At. It is also contraindicated on broken skin, mucous membranes, or extensive body surface areas without medical supervision. Patients with severe liver disease or those taking interacting systemic medications should consult a healthcare professional before use.
