Pronunciation

Generic Name: acyclovir (ay-SYE-kloe-vir)
Brand Name: Zovirax

Acyclovir suspension is used for:

Treating shingles or chickenpox, or treating or suppressing genital herpes. It may also be used for other conditions as determined by your doctor.

Acyclovir suspension is an antiviral. It works by preventing the herpes virus from reproducing. Acyclovir does not eliminate the virus and is not a cure. It does not prevent transmission of the virus to others.

Do NOT use acyclovir suspension if:

  • you are allergic to any ingredient in acyclovir suspension or to valacyclovir

Contact your doctor or health care provider right away if any of these apply to you.

Important safety information:
