Indications and Purpose
How does Acyclovir work?
Acyclovir works by targeting the herpes virus. Once it's in the body, it is taken up by infected cells where the virus is active. Acyclovir is converted into its active form and interferes with the virus's ability to replicate by blocking a key enzyme the virus needs to make copies of itself. This helps stop the spread of the infection, reduces symptoms, and speeds up healing, though it doesn't completely eliminate the virus from the body.
