Drug Information

ACHC is intended for the early treatment of recurrent herpes simplex labialis (HSL) in adults and adolescents (12 years of age and older). It is designed for cutaneous use only and is applied to the lips and skin around the mouth. Usage should be avoided on the eyes, inside the mouth or nose, and on the genitals. The patient should be instructed to apply a thin layer across the affected area, including the outer margins of the cold sore. Treatment should be initiated at the first sign or symptom (prodromal stage), applying 5 times per day for a period of 5 consecutive days. If there is no noticeable improvement and/or the cold sore fails to heal within 2 weeks, patients are encouraged to seek further medical attention. At present, the efficacy of ACHC has not been established in the immunocompromised population.[5]
