Zovirax tablets contain acyclovir, an antiviral medication. Acyclovir mimics a building block of viral DNA, preventing the herpes simplex virus (HSV) – the culprit behind cold sores – from replicating. This stops the virus from spreading and allows your body’s immune system to fight off the infection more efficiently.
Targeting Viral Replication
Specifically, acyclovir inhibits viral DNA polymerase, an enzyme HSV needs to copy its genetic material. By interfering with this process, acyclovir significantly reduces the amount of virus produced, thus shortening the duration and severity of your cold sore outbreak. This means faster healing and less discomfort.
Important Considerations
Remember that Zovirax tablets treat symptoms and reduce the duration of outbreaks, they don’t cure the HSV infection. The virus remains dormant in your body, potentially causing future outbreaks. Always follow your doctor’s instructions regarding dosage and treatment duration for optimal results. Early treatment is key to minimizing the impact of a cold sore.
