Zovirax eye ointment

How does it work?

Zovirax eye ointment contains the active ingredient aciclovir, which is an antiviral medicine. Aciclovir is used to treat infections with the herpes simplex virus.

Aciclovir works by stopping the herpes simplex virus from reproducing and infecting more cells.

Aciclovir is converted to a more active form inside cells of the body that are infected with herpes simplex. The activated aciclovir then works by blocking the action of a viral enzyme called DNA polymerase.

The herpes virus needs the DNA polymerase enzyme to copy its genetic material from RNA to DNA. This process is necessary for the virus to multiply and continue to survive. By blocking the action of DNA polymerase, aciclovir prevents the herpes virus from multiplying. This controls the infection and helps the immune system to deal with it.

Zovirax eye ointment is specially formulated to treat inflammation of the front of the eye (cornea) caused by infection with the herpes simplex virus. This serious infection is called herpes simplex keratitis. Treatment with this medicine should continue for at least three days after the eye has healed to ensure the infection has cleared up fully. Follow the instructions given by your doctor.
