Why is Lamisil prescribed?

Lamisil fights fungal infections. In tablet form, it"s used for fungus of the toenail or fingernail. The cream and the solution are used for other fungal infections such as athlete"s foot, jock itch, and ringworm. The solution is also used to treat tinea versicolor, a fungal infection that produces brown, tan, or white spots on the trunk of the body.

Most important fact about Lamisil

Lamisil does not produce instant results. You won"t see the full effect of the tablets for several months, until a healthy new nail has grown out. The cream and solution also work gradually. It usually takes a week for results to appear, and improvement often continues for 2 to 6 weeks after treatment has stopped. However, if you see no change at all after a full week of applying the cream or solution, notify your doctor. The problem may be other than fungal.

How should you take Lamisil?

Before applying Lamisil solution, clean and dry the infected area thoroughly. Use enough solution to fully wet the entire area. When using either the solution or the cream, do not cover the treated area with dressings unless directed by your doctor.

Continue using Lamisil for the full amount of time your doctor prescribes, even if your symptoms begin to improve.

--If you miss a dose...

Take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and return to your regular schedule. Do not take two doses at one time.

--Storage instructions...

Store the tablets at room temperature, away from light in a tight container. The cream and solution should be stored at room temperature, and not refrigerated.
