Cold sores resolve after 7–10 days without treatment. Topical anti-virals applied pro-dromally reduce duration by 12-24hrs 1,2,3B+
Prophylaxis may be considered for patients who suffer from severe recurrent cold sores

Principles of Treatment

  1. This guidance is based on the best available evidence but its application must be modified by professional judgement.
  2. Where a ‘best guess’ therapy has failed or special circumstances exist, microbiological advice can be obtained from LTHT Microbiology (Mon-Fri 9am-5pm and Sat and Sun 9am-1pm: 0113 39 23962/28580; Otherwise via LTHT switchboard - ask for the On call Microbiology Registrar)

Adapted from:

This guidance was initially developed in 1999 by practitioners in South Devon, as part of the S&W Devon Joint Formulary Initiative, and Cheltenham & Tewkesbury Prescribing Group and modified by the PHLS South West Antibiotic Guidelines Project Team, PHLS Primary Care Co-ordinators and members of the Clinical Prescribing Sub-group of the Standing Medical Advisory Committee on Antibiotic Resistance. It was further modified following comments from Internet users. The guidance has been updated annually as significant research papers, systematic reviews and guidance have been published. The Health Protection Agency works closely with the authors of the Clinical Knowledge Summaries.

Seek specialist advice if long-term prophylaxis is being considered.
