Famciclovir is an antiviral medication that targets the herpes simplex virus, reducing the duration and severity of cold sore outbreaks. It works by inhibiting viral replication.
Famciclovir is recommended for individuals with recurrent or severe cold sores who need fast and effective symptom relief.
It is typically taken as a single high-dose treatment at the first sign of symptoms, such as tingling or itching, to stop the outbreak early.
Famciclovir is prescribed for adults with recurrent cold sores and should be taken at the first sign of symptoms, such as tingling or itching, for best results. Patients who are pregnant, breastfeeding, or have kidney conditions should consult their clinician before use. See pricing details here.
