What is Lamisil?

Lamisil (terbinafine) is an antifungal antibiotic.

Lamisil is used to treat infections caused by fungus that affect the fingernails or toenails. Lamisil oral granules are used to treat a fungal infection of scalp hair follicles in children who are at least 4 years old.
Before using Lamisil, tell your doctor if you have liver or kidney disease, or an autoimmune disorder such as lupus or psoriasis.

Take Lamisil for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Lamisil will not treat a viral infection such as the common cold or flu. Some people taking this medicine have developed severe liver damage leading to liver transplant or death. It is not clear whether Lamisil actually caused the liver damage in these patients. In most cases, the patient had a serious medical condition before taking Lamisil.

Call your doctor at once if you have symptoms of liver damage, such as nausea, upper stomach pain, itching, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes). These events can occur whether or not you have ever had liver problems before.

To be sure this medicine is not causing harmful effects, your blood may need to be tested often. Your liver function may also need to be tested. Visit your doctor regularly.

It may take several months for your nails to return to their normal appearance after your treatment with Lamisil.
