Lamisil® Tablets for Fungal Nail Infection

Lamisil® is an antifungal medicine used for nail and common skin infections caused by dermatophytes. This page outlines how it works, who it may suit, and how to use it safely. You can review options at Canadian rates with US delivery from Canada, even when paying without insurance.

What Lamisil Is and How It Works

Lamisil® belongs to a class of antifungal medicines called allylamines. It stops fungi from making ergosterol, a key part of fungal cell membranes. Without it, the cell membrane weakens and the fungus can no longer grow. Tablets are used for fungal nail infections, while creams and gels are used for athlete’s foot, jock itch, and ringworm on the skin.

Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing.

Many people first notice improvement in skin symptoms within days, while nails take longer to show healthy growth. Clearing the infection may take a full course and continued nail growth. See our condition guides on Nail Fungus and Fungal Skin Infection for background.

For systemic treatment of nail disease, Lamisil oral tablets are typically prescribed by a clinician. For localized skin infections, topical terbinafine may be preferred. Choose the form your prescriber recommends based on site and severity.

Who It’s For

This treatment is for adults diagnosed with fungal nail infection or tinea of the skin confirmed or suspected by a clinician. It is not effective for infections caused by bacteria or viruses. Topical forms are for external use on skin only.

People with chronic or active liver disease should avoid tablets. Tell your healthcare professional if you have kidney problems, lupus, or a history of serious skin reactions. Discuss all medicines you use, including herbals. Lamisil is not a substitute for proper foot care; see our Diabetic Foot Ulcers guide if you have diabetes and foot concerns.

Dosage and Usage

Follow your prescriber’s directions and the official label. Tablets are usually taken once daily with or without food, at about the same time each day. Many clinicians suggest a full course for toenails and a shorter course for fingernails. Your clinician may check baseline liver status before starting oral therapy.

For skin infections, clean and dry the area. Apply a thin layer of the cream or gel to the affected skin and surrounding areas as directed, and wash your hands after use. Avoid eyes, mouth, and vaginal area. Keep using it for the entire labeled duration, even if symptoms improve earlier.

For reference only, a common oral strength is 250 mg once daily. Always defer to the product label and your prescriber for specific directions.

Strengths and Forms

Availability can vary by supplier and country. Common presentations include:

• Tablets: often supplied as 250 mg
• Topicals for skin: cream, gel, or spray, frequently as 1% formulations

Tablets are typically used for nail involvement, while topicals are for skin-only infections like athlete’s foot. See our Dermatology category or country-of-origin filter for options sourced from Canada.

Missed Dose and Timing

For tablets: if you miss a dose, take it when you remember unless it is near the next dose. If it is close, skip the missed dose and resume your regular schedule. Do not double up. For topical products, apply the next dose when remembered and continue as directed. Try setting reminders to support daily adherence.

Storage and Travel Basics

Store tablets and topicals at room temperature, away from excessive heat and moisture. Keep the cap tightly closed on creams and gels. Do not freeze. Keep all medicines out of reach of children and pets. When traveling, carry your medication in your hand luggage with the original label, and bring a copy of your prescription or a photo of the label if asked to verify. Avoid leaving products in hot cars or direct sunlight for extended periods.

Benefits

This antifungal targets the source of infection and can clear fungus from nails and skin when used as directed. Tablets offer once-daily convenience for nail disease. Topical forms limit body-wide exposure for skin-limited infections. Many users find the class effective across common dermatophyte infections. Adherence to the full course helps reduce recurrence.

Side Effects and Safety

• Tablets: headache, upset stomach, diarrhea, taste changes, or loss of appetite
• Topicals: mild burning, itching, irritation, or dryness at the application site

Rare but serious risks include severe liver problems, serious skin reactions, allergic reactions, smell or taste disturbances that may persist, and worsening lupus symptoms. Stop the medicine and seek medical help if you notice yellowing skin/eyes, dark urine, severe rash, blistering, swelling of face or throat, or trouble breathing. Report new or persistent taste or smell changes to your prescriber.

Drug Interactions and Cautions

Oral terbinafine can affect other medicines. It inhibits CYP2D6 and may raise levels of certain antidepressants, antipsychotics, beta-blockers, and Type 1C antiarrhythmics. Rifampin may lower terbinafine exposure, while cimetidine may increase it. Warfarin effects can change. Limit alcohol, and discuss caffeine use if sensitive. Tell your clinician about all prescription and OTC products, vitamins, and herbals.

What to Expect Over Time

Skin symptoms may improve within several days, but complete clearing can take the full labeled course. Nails grow slowly, so visible clearing may lag behind fungal eradication. Expect new healthy nail to replace damaged nail over months after treatment is completed. Keep nails trimmed, dry, and clean. Use breathable footwear and change socks daily to reduce moisture. Consider preventive measures if your environment or activities increase exposure to fungi.

Compare With Alternatives

For nail infections limited to the nail plate, a topical option like Jublia® may be considered by some prescribers. For athlete’s foot and other skin-only infections, an OTC option such as Flexitol Anti Fungal may suit mild cases. Your clinician can help choose the right approach based on site, severity, and medical history.

Patient Suitability and Cost-Saving Tips

Good candidates have confirmed dermatophyte infection and can complete the full course. Those with active liver disease, certain drug interactions, or a history of severe skin reactions may need a different therapy. Discuss pregnancy and breastfeeding with your healthcare professional before use.
