Terbinafine Hydrochloride: Brands, Price & Uses in Bangladesh

Oral Tablet – Onychomycosis (Fungal Nail Infection)

Terbinafine Hydrochloride 250 mg oral tablets are indicated for the treatment of onychomycosis (fungal infection) of the toenail or fingernail caused by dermatophytes (tinea unguium). This is an established, regulatory-approved indication. Appropriate nail specimens should be tested to confirm the fungal diagnosis before Terbinafine Hydrochloride is started, since oral therapy is reserved for confirmed dermatophyte nail infections.

Topical Cream / Gel / Spray – Tinea Pedis, Tinea Cruris, and Tinea Corporis

Terbinafine Hydrochloride 1% topical cream, gel, and spray are indicated for the treatment of tinea pedis (athlete's foot), tinea cruris (jock itch), and tinea corporis (ringworm) caused by susceptible dermatophytes. This is an established indication supported by the regulatory labeling of topical Terbinafine Hydrochloride products.

Topical Cream / Gel – Cutaneous Candidiasis and Pityriasis Versicolor

Topical Terbinafine Hydrochloride 1% cream/gel is also used for cutaneous candidiasis and pityriasis versicolor (tinea versicolor), per product labeling of Terbinafine Hydrochloride marketed in Bangladesh. This use is guideline-supported for these specific yeast infections; the exact regimen and expected response can differ from dermatophyte skin infections, so it should be confirmed by a qualified healthcare professional.

The dose, frequency, and length of treatment with Terbinafine Hydrochloride differ substantially between the oral 250 mg tablet and the topical 1% cream, gel, or spray, and also vary depending on which fungal infection is being treated. The regimens described below are general reference points; the specific dosing schedule for Terbinafine Hydrochloride in any individual patient must always be determined by a qualified healthcare professional.
