Zovirax® Duo FAQs

Find the answers to your most frequently asked questions about Zovirax® Duo, the only non-prescription cold sore medication that combines an anti-inflammatory agent with an antiviral.


Applying Zovirax® Duo

  • What happens if I swallow some Zovirax® Duo?

    If you accidentally use too much or swallow the cream, it is unlikely that any untoward effects would occur. However, if you swallow a large amount of the cream, it is recommended that you speak to a doctor or pharmacist.

  • Can I apply cosmetics on top of it?

    Yes. Cosmetics, such as lipstick, may be applied over Zovirax® Duo once it is dry. However, use a separate applicator (like a cotton swab) to apply cosmetics or sunscreen over an unhealed cold sore. This helps to avoid spreading the infection. Please, remove any cosmetics prior to applying/reapplying Zovirax® Duo.
