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.

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

• fever, chills, body aches, flu symptoms;
• changes in your vision;
• weight loss due to taste changes;
• scaly, itchy, and flaky skin rash; or

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;
