How is Zovirax Duo different from other cold sore products?

It is the only cold sore medicine that combines an anti-inflammatory agent (1% hydrocortisone) with an antiviral agent (5% aciclovir). It helps prevent the blister when applied at the first signs and speeds up healing if a blister develops.

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.

Using Zovirax Duo

When should I use Zovirax Duo?

For best results, start applying Zovirax Duo at the first sign of a cold sore; the tingle, redness, bump or itch. Use Zovirax Duo five times a day for five days.

Can I start using Zovirax Duo after the blister has developed?

Best results are seen when Zovirax Duo is used at the tingle stage. If a cold sore does go on to develop, despite treatment being started at tingle, you can continue using Zovirax Duo to help speed healing. If a blister has developed before you start to treat, you can use Zovirax Cold Sore Cream – its unique formulation efficiently fights the virus that causes cold sores at the tingle or blister stage.
