Oral medications for toenail fungus infections are very powerful treatments. It is important to have a clear understanding of these medications before taking this action to cure toenail fungus. Some people taking terbinafine (Lamisil) have developed severe liver damage leading to liver transplant or death. This is not to say that these side effects are common but it is something that all potential users of Lamisil should be aware of. It is not always clear whether terbinafine was certainly what caused the liver damage in these patients since many of them had a serious pre-existing medical condition of some kind, which caused the fungal infection in the first place.
Call a medical professional at once if you suspect that you have symptoms of liver damage, such as nausea, upper stomach pain, itching, appetite loss, dark. In addition, if you demonstrate any signs of an allergic reaction such as hives, difficulty breathing, or swelling of your face, lips, tongue, or throat; seek medical attention.
