Herpes Labialis (Cold Sore) Management with Lysine Supplements

Herpes labialis, commonly referred to as cold sores, remains one of the most prevalent viral infections affecting the orofacial region. Dental professionals and clinicians frequently encounter patients seeking guidance on effective prevention and management of recurrent episodes. Recent years have seen increased interest in non-pharmaceutical interventions that may complement conventional antiviral therapies and improve patient outcomes. Among the various complementary approaches, lysine supplementation has garnered significant attention for its proposed role in modulating herpes simplex virus activity and reducing outbreak frequency. Understanding the biochemical mechanisms, safety considerations, and current clinical evidence associated with lysine use is essential for practitioners involved in patient care and counseling. This course provides an in-depth examination of herpes labialis pathophysiology, reviews established and emerging treatment strategies, and evaluates the scientific basis behind lysine supplementation for the management of cold sores. Participants will learn to integrate evidence-based recommendations into clinical protocols and patient education to optimize prevention and improve quality of life.
