Terbinafine Cream
Treatment for Ringworm and Jock Itch

Terbinafine cream is a topical antifungal medicine containing terbinafine hydrochloride as the active ingredient. It is used to treat fungal skin infections caused by dermatophyte fungi, including ringworm (tinea corporis) and jock itch (tinea cruris). It is an MHRA-approved treatment available from My London Pharmacy following a short online consultation.

Terbinafine cream works by inhibiting an enzyme called squalene epoxidase, which is essential for the production of ergosterol — a key component of fungal cell membranes. Without ergosterol, the fungal cells become weakened and eventually die. Unlike some antifungal treatments that only stop fungal growth, terbinafine is fungicidal, meaning it actively kills the fungi responsible for the infection.

Terbinafine cream is a clinically proven and highly effective treatment for dermatophyte fungal infections. When used correctly and consistently, it clears the majority of ringworm and jock itch infections within one to two weeks. Effectiveness depends on applying the cream to the correct area, using it for the full recommended course, and keeping the affected skin clean and dry during treatment.

Most people notice an improvement in symptoms such as itching, redness, and scaling within the first few days of treatment. Visible clearing of the infection typically occurs within one to two weeks. It is important to continue using the cream for the full course of treatment even if symptoms appear to resolve early, to ensure the infection is completely cleared and reduce the risk of recurrence.

Wash and dry the affected area thoroughly before applying the cream. Apply a thin layer of terbinafine cream to the infected skin and the area immediately surrounding it. Allow the cream to absorb before covering the area with clothing. Wash your hands immediately after every application. Apply the cream once or twice daily as directed. Do not apply to the eyes, nose, or mouth, and avoid broken or inflamed skin unless directed by your prescriber.

Terbinafine cream is suitable for adults and adolescents over the age of 12 with a localised dermatophyte fungal skin infection such as ringworm or jock itch. It is not appropriate for fungal nail infections, scalp ringworm, or widespread infections — these may require oral terbinafine tablets instead. A clinician will confirm suitability during your online consultation.

Terbinafine cream should not be used by anyone with a known allergy to terbinafine or any other ingredient in the formulation. It is not recommended for use on the scalp or nails. If you are pregnant, breastfeeding, or have any significant medical conditions, please discuss this with your prescriber before use. This cream is not suitable for children under 12 without specific medical advice.

The cream itself does not spread infection, but you should wash your hands thoroughly after every application to avoid transferring the fungus to other areas of your body or to other people. Avoid sharing towels, clothing, or bedding during the course of treatment, as ringworm and jock itch are contagious and can spread through contact with contaminated items.

Terbinafine cream is generally well tolerated. The most commonly reported side effects are mild and localised, including redness, itching, burning, or stinging at the application site. These effects are usually temporary. Allergic reactions are rare but possible. If you experience significant skin irritation, rash, or swelling after applying the cream, stop use and seek advice from My London Pharmacy or your GP.

The recommended treatment duration is typically one to two weeks for ringworm and jock itch, used once or twice daily as directed. Always complete the full course of treatment even if your symptoms improve before the end of the recommended period. Stopping early increases the risk of the infection returning.
