Management
Recurrent herpetic lesions are usually treated with topical antiviral medications. Topical penciclovir reduces the duration and pain of recurrent lesions by 1–2 days. Patients are recommended to apply topical penciclovir over the affected site for every 2 h for 4 days while awake. Topical acyclovir is also available for topical use and reduces the duration of recurrent herpes lesions by 12 h. Topically acyclovir is also recommended in recurrent herpes infections and is usually effective when the lesions commenced during prodromal symptoms. Vander et al. mentioned that the benefit of applying acyclovir is limited when compared with topical penciclovir. Oral or intravenous administration of acyclovir is usually effective in immunocompetent patients. However,cases of acyclovir-resistant HSV have been reported,and foscarnet has been an effective therapy for acyclovir-resistant patients. Valacyclovir should be used with caution for immunocompetent patients due to the potential risk of hemolytic uremic syndrome. Recommended drug dosage and regimens used to treat recurrent oral HSV infections are given in [Table 2](https://ncbi.nlm.nih.gov/pmc/articles/PMC7014888/table/T2/) .","department":"
