What Is Terbinafine?
Lamisil (terbinafine) is a prescription antifungal medication used to manage onychomycosis, commonly called fungal nail infection. It works by inhibiting squalene epoxidase, an enzyme essential to fungal cell membrane synthesis, causing fungal cells to accumulate squalene and die. With the right dose and ongoing monitoring, most patients see clear nail regrowth after completing a full course of therapy.

Is Online Terbinafine Treatment Right for You?
To qualify for a terbinafine refill through Doctronic, you must have an existing diagnosis of onychomycosis or another fungal skin infection for which terbinafine was previously prescribed, and your current course of treatment must be ongoing or recently completed with a need for continuation.
Because terbinafine is processed by the liver, your prescribing history and any relevant liver function information will be reviewed by a licensed physician before a refill is issued. Patients with a history of liver disease or those taking medications that interact with terbinafine may require additional clinical review.

Frequently asked questions
The standard course is 6 weeks for fingernail infections and 12 weeks for toenail infections. Because nails grow slowly, it can take several additional months after completing treatment before the nail appears fully clear.
Terbinafine is metabolized by the liver and, in rare cases, can cause liver enzyme elevations or more serious hepatic effects. Baseline liver function tests are recommended before starting treatment, and monitoring may continue during longer courses. Your physician will review your history before issuing a refill.
Terbinafine inhibits the liver enzyme CYP2D6 and can increase blood levels of certain drugs, including some antidepressants and beta-blockers. Always provide a complete medication list so your physician can screen for interactions before renewing your prescription.
Some patients require retreatment or a longer course. If you have completed a full course and improvement is limited, your physician may reassess the diagnosis, confirm the infecting organism, or discuss alternative antifungal options.
Alcohol is not strictly contraindicated, but because both alcohol and terbinafine can affect liver function, it is advisable to limit alcohol consumption during your course of treatment and discuss any concerns with your physician.
Yes. Terbinafine tablets and cream are used to treat tinea pedis (athlete's foot), tinea corporis (ringworm), and tinea cruris (jock itch), among other dermatophyte infections. The refill page focuses on the most common indication, onychomycosis, but your physician will review your specific diagnosis.
