Indications

Amenamevir tablet is used to treat herpes simplex, recurrent herpes simplex and herpes zoster. It works in a different way from other antivirals, so it may be an alternative for patients who have developed resistance to other antiviral medicines.

⚠️ Always consult a registered physician before taking any medicine.

Pharmacology

Amenamevir blocks the viral helicase-primase complex. This is an enzyme the virus needs to unwind its DNA and to make the primers used when the viral DNA is copied. Older antiviral medicines such as acyclovir and valaciclovir work in a different way, because they target viral DNA polymerase.

Pregnancy & Breastfeeding

Pregnancy: Studies in mice and rabbits found no harmful effects on the mothers or on the development of the fetus at certain doses. The report does not, however, give any specific advice on whether Amenamevir is safe for pregnant women.

Lactation: There is no specific information about using Amenamevir while breastfeeding.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.
