# Aciclovir 5% W/W ## SHORT DESCRIPTION **Aciclovir 5% W/W** is a topical antiviral medicine used to help treat **herpes simplex virus (HSV) infections of the skin**, including recurrent **cold sores (herpes labialis)** and certain localized genital herpes lesions when prescribed. Aciclovir works by interfering with viral DNA replication, helping reduce the growth and spread of the herpes virus. It works best when started **as early as possible after symptoms begin**. ## KEY BENEFITS * Helps treat localized herpes simplex skin infections * Helps reduce viral multiplication * May shorten the duration of herpes lesions when started early * Can help reduce pain, burning, and discomfort associated with lesions * Useful for recurrent cold sores in appropriate patients * Acts directly at the site of application ## USES / INDICATIONS Aciclovir 5% cream may be used for: * **Herpes simplex virus (HSV) skin infections** * Recurrent **cold sores / herpes labialis** * Localized herpes simplex lesions * Certain localized genital herpes lesions when specifically prescribed It is **not effective against fungal or bacterial skin infections**. ## HOW IT WORKS Aciclovir is an **antiviral medicine**. After entering herpes-infected cells, aciclovir is converted into its active form by viral enzymes. The active medicine inhibits **viral DNA polymerase**, interfering with the virus's ability to replicate its DNA. This helps limit the multiplication of HSV and supports healing of the lesions. Aciclovir does **not completely eliminate herpes virus from the body**, and the virus can remain dormant and reactivate later. ## DOSAGE & ADMINISTRATION For many topical aciclovir 5% preparations, the usual application is: * Apply a thin layer to the affected area **approximately every 4 hours while awake, usually 5 times daily**. * Treatment is commonly continued for around **4 days for cold sores**, although the exact duration depends on the product and medical advice. * For other herpes infections, the duration may be different. ### How to Apply 1.
