What are the possible side effects of terbinafine (Lamisil)?

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Some people taking terbinafine have developed severe liver damage leading to liver transplant or death. It is not clear whether terbinafine actually caused the liver damage in these patients. In most cases, the patient had a serious medical condition before taking terbinafine.

Call your doctor at once if you have symptoms of liver damage, such as nausea, stomach pain, loss of appetite, itching, 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.

Stop taking terbinafine and call your doctor at once if you have a serious side effect such as:

  • joint pain or swelling, swollen glands, patchy skin color, or a butterfly-shaped skin rash over your cheeks and nose;
  • fever, chills, body aches, flu symptoms;
  • changes in your vision;
  • weight loss due to taste changes;
  • scaly, itchy, and flaky skin rash; or
  • fever, sore throat, and headache with a severe blistering, peeling, and red skin rash.

Less serious side effects may include:

  • stomach pain, heartburn, diarrhea;
  • headache;
  • tired feeling;
  • runny or stuffy nose, sore throat, cold symptoms;
  • mild skin rash or itching;
  • unusual or unpleasant taste in your mouth; or
  • decreased taste sensation.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

What is the most important information I should know about terbinafine (Lamisil)?

Before using terbinafine, tell your doctor if you have liver or kidney disease, or an autoimmune disorder such as lupus or psoriasis.

Take this medication for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Terbinafine will not treat a viral infection such as the common cold or flu.

Some people taking terbinafine have developed severe liver damage leading to liver transplant or death. It is not clear whether terbinafine actually caused the liver damage in these patients. In most cases, the patient had a serious medical condition before taking terbinafine.

Call your doctor at once if you have symptoms of liver damage, such as nausea, stomach pain, loss of appetite, itching, 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 medication is not causing harmful effects, your blood may need to be tested on a regular basis. Your liver function may also need to be tested. Do not miss any scheduled appointments.

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