How to use Zovirax Duo

Zovirax Duo is clinically proven to help prevent blisters before they start


Zovirax Duo is a breakthrough cold sore treatment. It’s clinically proven to help prevent a cold sore blister when applied at the first tingle and speed up healing time if the blister develops.

  • First sign

    Apply at the first sign of a cold sore tingle, bump or itch for the best results. The sooner you apply, the better your chance of keeping a blister or scab from forming.

  • 12 years+

    Recommended for adults and children 12 years and over only.

  • Keep it clean

    Remove any cosmetics before applying Zovirax Duo. Always wash your hands with soap and water before and after treating your cold sore.

  • Don’t skimp or skip

    Apply five times during the day with a cotton swab or your finger. Use enough to completely cover the affected area. Just rub in gently and completely. If you miss a dose, just apply the next time you remember and continue on schedule. Wash your hands after applying the cream.

  • Don’t share

    Cold sores are contagious. Don’t share your tube with anybody else.

  • Make it up

    You can apply cosmetics like lipstick over Zovirax Duo, after it has completely dried. Always use a separate make-up applicator, like a cotton swab to avoid spreading the infection.

  • Five days

    Use Zovirax Duo for five days. If the cold sore persists and is still present after 10 days, talk to your healthcare professional.
