What is Lamisil?
Lamisil, also known as Terbinafine, is in a class of medications called antifungals. It is prescribed to treat fungal infections of the fingernail and toenail and works by stopping the growth of the fungi.
Rare cases of liver failure, some leading to death or liver transplant, have occurred with the use of Lamisil. Hepatoxicity may occur in patients with and without pre-existing liver disease. There have also been isolated reports of serious skin reactions

As of March 2001, the FDA had reviewed a number of possible Lamisil-associated cases of liver failure, including two that required liver transplants and another 11 ending in death. Given the possible serious risks, new labeling recommended that healthcare providers perform testing to confirm the diagnosis, prior to prescribing the drug.
On May 9, 2001 the FDA issued a Public Health Advisory to announce significant safety-related updates to the labeling of Lamisil tablets.
