Valaciclovir

Valaciclovir is an antiviral medication that helps manage herpes simplex virus (HSV) infections, including genital herpes, cold sores, and other skin infections caused by HSV. It is converted into Aciclovir once in the body, offering more prolonged effectiveness with fewer doses.

Valaciclovir works by preventing the herpes virus from reproducing, helping to reduce pain and speed up healing. Since it’s better absorbed in the body compared to Aciclovir, it stays in the system longer, meaning it needs to be taken less frequently. This treatment can also reduce the risk of transmitting the infection.

• For genital herpes, take 500mg twice daily for 5 days. If it's your first outbreak, the treatment may be extended to 10 days.
• For suppressive therapy, take 500mg once daily to reduce the frequency of outbreaks.
• It's important to stay hydrated during treatment, as Valaciclovir can put strain on the kidneys.
