Lamisil Dermgel (Terbinafine)

Terbinafine belongs to the allylamine class of antifungals. It blocks the fungal enzyme squalene epoxidase, preventing the synthesis of ergosterol, an essential component of fungal cell membranes. The resulting buildup of squalene and loss of ergosterol disrupts membrane integrity, leading to fungal cell death.

The specific dosing regimen for Lamisil Dermgel is determined by the prescribing healthcare professional based on the infection type, severity, and patient factors. Typically, the gel is applied once daily to the affected area for a prescribed number of weeks, but exact instructions should always follow the prescriber’s order.

Safety data for topical terbinafine in pregnancy and lactation are limited. It should only be used if the potential benefit justifies any possible risk to the fetus or infant. Women who are pregnant, planning pregnancy, or breastfeeding should discuss use with their healthcare provider.

To place an order, submit an enquiry on the product page at gnhindia.com specifying the required quantity of Lamisil Dermgel. GNH India supplies hospitals, pharmacies and procurement teams worldwide, and will request verification of trade or institutional credentials before providing pricing, availability, shipping details and any required import documentation.

Compared with azole antifungals, terbinafine has a different mechanism—blocking squalene epoxidase rather than inhibiting lanosterol 14α‑demethylase. This often results in a shorter treatment duration for dermatophyte infections. Terbinafine also tends to have a lower risk of drug‑drug interactions than many systemic azoles, though topical formulations are generally well tolerated.

Store Lamisil Dermgel at room temperature, preferably below 25 °C. Keep the product in its original packaging, protect it from moisture, direct sunlight and excessive heat. Ensure the container is tightly closed when not in use to maintain gel integrity.

Clean and dry the affected skin area before application. Apply a thin layer of the gel to the lesion and surrounding skin, gently rubbing it in until fully absorbed. Wash hands after use unless the hands are the treatment site. Follow the prescriber’s frequency and duration instructions.

While most reactions are mild, serious adverse events can include severe allergic reactions such as angioedema or anaphylaxis, Stevens‑Johnson syndrome, extensive skin blistering, and rare systemic effects like liver enzyme elevation. Any signs of severe rash, swelling, or systemic symptoms should prompt immediate medical attention.

Lamisil Dermgel should be avoided in individuals with known hypersensitivity to terbinafine, other allylamine antifungals, or any component of the formulation. It is also contraindicated on broken or severely inflamed skin, and caution is advised for patients with significant liver disease or those who are pregnant or breastfeeding without medical guidance.
