BACKGROUND Herpes simplex virus type 1 infection usually causes a mild, self-limiting painful blistering around the mouth, with 20% to 40% of adults affected at some time. Primary infection usually occurs in childhood, after which the virus is thought to remain latent in the trigeminal ganglion. Recurrence may be triggered by factors such as exposure to bright light, stress, and fatigue. METHODS We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of antiviral treatments for the first attack of herpes labialis? What are the effects of interventions aimed at preventing recurrent attacks of herpes labialis? What are the effects of treatments for recurrent attacks of herpes labialis? We searched: Medline, Embase, The Cochrane Library, and other important databases up to February 2009 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). RESULTS We found 27 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. CONCLUSIONS In this systematic review we present information relating to the effectiveness and safety of the following interventions: oral antiviral agents, sunscreen, topical anaesthetic agents, topical antiviral agents, and zinc oxide cream.

D006560	Herpes Labialis	Herpes simplex, caused by type 1 virus, primarily spread by oral secretions and usually occurring as a concomitant of fever. It may also develop in the absence of fever or prior illness. It commonly involves the facial region, especially the lips and the nares. (Dorland, 27th ed.)

D000779	Anesthetics, Local	Drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They act on any part of the nervous system and on every type of nerve fiber. In contact with a nerve trunk, these anesthetics can cause both sensory and motor paralysis in the innervated area. Their action is completely reversible. (From Gilman AG, et. al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed) Nearly all local anesthetics act by reducing the tendency of voltage-dependent sodium channels to activate.

D000998	Antiviral Agents	Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly.
