Canker Sores and Cold Sores.  What is the Difference?

Cold Sores, also called Fever Blisters, are caused by the Herpes Simplex Virus (HSV-1 and HSV-2).  They are often preceded by a mild fever, sore throat, swollen glands (lymph nodes), fatigue, and a buzzing or itching pain on the lip or cheek.  Over 24 hours the lesion presents as a small, tight grouping of fluid filled vesicles that can break and leak fluid.  Blisters usually scab over within two or three days and are completely healed in ten.  

Cold sores are often quite painful, but early treatment with medications (acyclovir, valacyclovir) can help keep lesions smaller and less painful.  Medications may also help reduce the likelihood of passing on the infection.

DEBACTEROL®  is not indicated for the treatment of vesicular lesions (e.g., Cold Sores, Fever Blisters)
