Current diagnosis and management of herpes labialis
Diagnosis of herpes labialis by GPs is usually based on the patient history of this condition, the clinical signs and symptoms. Laboratory confirmation, however, may be required in immunocompromised patients if the clinical presentation is atypical.
Many patients neither require nor use any treatment because the disease is self-limiting.20 For individuals with frequent recurrences, application of a sunscreen or zinc oxide to decrease the probability of recurrent outbreaks may help. 21, 22 Some
Risks versus benefits of reclassification of antiviral therapy
Despite the recent publication of an evidence-based review suggesting that oral antiviral agents are more beneficial than topical agents for treating recurrent episodes,21 antiviral tablets are currently only available by prescription (POM or Rx only) in most countries. Availability would be facilitated by a product being reclassified as a pharmacy-only (pharmacist-controlled) medicine. This is defined as a product that can be obtained without a prescription provided that a pharmacist is
Pharmaco-economic benefits of OTC therapies
Generally, OTC therapies are more accessible and convenient than prescription medications and are usually cheaper because they are often generic.60 In some countries, patients may have to pay the full cost of a POM but, in others, patients may only have to pay a fixed prescription charge that could be the same or less than the OTC price. The change from POM to OTC status of medications has been the direction followed by more than 700 treatments over the past 30 years and has led to annual
Conclusions
Initial diagnosis of herpes labialis should be made by GPs. With patient education, thereafter, a significant reduction in a GP's work burden, as well as cost-savings for both the patient and the GP, could result from the availability of pharmacy-controlled antiviral medication for herpes labialis. Another important consideration is reducing the delay in the start of treatment, with patients being able to self-medicate as soon as they feel the prodrome of a herpes labialis outbreak. Suitable

It can become reactivated under various stimuli: stress, fever, ultraviolet light, trauma, or menstruation.15 On reactivation of herpes lesions, the patient first experiences the prodromal symptoms of pain, itching, burning, or paresthesia.16
