The recommended dosage for suppression therapy for recurrent outbreaks is 1,000 mg of valacyclovir once a day or 400 mg Acyclovir taken twice a day. In addition to preventing outbreaks, these medications greatly reduce the chance of infecting someone while the patient is not having an outbreak. [citation needed]

Dosage typically includes information on the number of doses, intervals between administrations, and the overall treatment period. [3] For example, a dosage might be described as "200 mg twice daily for two weeks," where 200 mg represents the individual dose, twice daily indicates the frequency, and two weeks specifies the duration of treatment.
These medications are acyclovir, valacyclovir, and famciclovir and have been shown to be safe with long-term use. Acyclovir is an antiviral medication and reduces the pain and the number of lesions in the initial case of genital herpes.

A separate list for children up to 12 years of age, known as the WHO Model List of Essential Medicines for Children (EMLc), was created in 2007 and is in its 9th edition.

Herpes meningitis is typically self-limiting over 2 weeks without treatment. However, empirical use of antiviral medications such as acyclovir are considered in cases of suspected HSV meningitis to prevent progression to the more rapid and fatal HSV meningoencephalitis. [7] HSV-2 is the most common herpes virus that causes meningitis. [3]
Guidelines, such as those provided by the Centers for Disease Control and Prevention (CDC) during the 2009 flu pandemic caused by the H1N1 virus, recommend, among other things, antiviral treatment regimens, clinical assessment algorithms for coordination of care, and antiviral chemoprophylaxis guidelines for exposed persons.
