Lamisil (terbinafine) is an antifungal medication used to treat common fungal infections such as athlete’s foot, ringworm, and onychomycosis (nail fungus). It comes in both oral and topical forms, depending on the severity and location of the infection.
While topical creams are effective for surface infections, tablet forms are often prescribed for deeper or stubborn nail and scalp conditions. Here’s how Lamisil works, how long treatment usually lasts, and what side effects to watch for.
Lamisil Product Description
Lamisil is a synthetic antifungal medication with high efficacy, widely used for the treatment of fungal infections affecting the skin, fingernails, and toenails. By disrupting the metabolism within fungal cells, Lamisil effectively destroys the infection at its source. This antifungal agent provides a fungicidal action and is prescribed to adults for managing common fungal conditions.
Lamisil is considered a trusted solution for treating onychomycosis (fungal nail infections) and dermatophytosis (fungal skin infections). Due to its broad-spectrum activity, it is particularly effective against conditions such as athlete’s foot (tinea pedis), ringworm of the body (tinea corporis), and jock itch (tinea cruris). Thanks to its proven results, Lamisil remains a preferred choice among healthcare providers for patients seeking reliable antifungal therapy.
Drug Uses
The standard daily dose of Lamisil for treating skin infections and onychomycosis is 250 mg. Treatment duration depends on the severity of the infection and the patient’s response to therapy. Typically, tinea cruris and tinea corporis require 2 to 4 weeks of treatment, while tinea pedis may take between 2 to 6 weeks. Nail infections, however, demand a longer course, lasting from 6 weeks up to 3 months. Early initiation of treatment helps to prevent the infection from spreading or worsening.
It is important to complete the entire course of therapy even if symptoms improve before finishing the medication. Stopping treatment prematurely can increase the risk of recurrence. In some cases, healthcare providers may combine oral Lamisil with topical formulations to enhance results, especially in stubborn skin infections.

Lamisil tablets are usually prescribed at 250mg once daily for 6–12 weeks, depending on the location and severity of the infection. Topical 1% cream is applied once or twice daily to the affected area for 1–4 weeks.
Missed Dose
If you miss a dose of Lamisil, take it as soon as you remember. However, if your next scheduled dose is within four hours, skip the missed dose and continue with your regular dosing schedule. Doubling doses is not recommended. Maintaining a consistent daily routine helps to maximize the drug’s effectiveness and ensures better treatment outcomes.
More Information
For patients dealing with severe or extensive skin infections, doctors may suggest combining Lamisil tablets with topical treatments such as Lamisil cream or spray. However, topical forms are not suitable for treating nail infections like onychomycosis. Oral therapy remains essential in these cases for deeper penetration into the nail bed.
To achieve optimal results, Lamisil tablets should be taken at the same time each day. It is advisable to take the medication on an empty stomach or 2-3 hours after eating. Patients should stay hydrated throughout the course of treatment and inform their healthcare provider of any other medications they are taking to avoid potential interactions.
Storage
Lamisil tablets should be stored at temperatures not exceeding 30°C (86°F), in their original packaging to protect from moisture and direct sunlight. Keeping the medication out of reach of children and pets is essential to avoid accidental ingestion.

Warnings
In rare cases, Lamisil may cause liver function impairment. Therefore, it is not recommended for individuals with chronic liver disease. Before starting therapy, liver function tests should be performed and monitored periodically during treatment. If symptoms such as persistent nausea, fatigue, or dark urine occur, contact your healthcare provider immediately.
Patients may occasionally experience taste or smell disturbances while using Lamisil. If these side effects arise, discontinuing the medication is often advised. Symptoms typically resolve within a few weeks after stopping the treatment. In rare instances, serious skin reactions such as Stevens-Johnson syndrome may develop. At the first sign of a skin rash, treatment with Lamisil should be discontinued, and medical attention sought promptly.
Lamisil Side Effects
Overall, Lamisil is well-tolerated, with most side effects being mild and temporary. Common adverse effects, reported in over 2% of patients, include liver enzyme abnormalities, decreased appetite, headaches, flatulence, and taste disturbances. Gastrointestinal issues like dyspepsia, diarrhea, abdominal pain, and nausea may also occur.
In rare cases, patients have reported mood changes or allergic reactions. It is essential to discuss any unusual symptoms with a healthcare provider. Regular check-ups during long-term therapy help to monitor for potential complications and ensure that the treatment is progressing safely and effectively.
By following medical advice and adhering to the prescribed regimen, most patients experience significant improvement in their symptoms and achieve complete recovery from fungal infections with Lamisil.
