# Cold sore creams

Check the antiviral ingredient, application schedule and when to seek help.

**What you need to know**

Some cold-sore creams contain an antiviral ingredient. The leaflet determines where, how often and for how long to apply a particular product. Seek advice for severe, persistent or unusual sores, and urgent advice if an eye may be affected.

This is an educational guide. Sanara is not taking orders or preorders. Compare the actual product’s label, suitability and total cost before buying from a retailer.

What to check before buying

## Check the label

- Active ingredient and licensed use
- Application frequency and course length
- Age limits and sites to avoid

## Directions and pack size

Use only as directed on the finished product’s label or patient information leaflet. Sanara has not verified a specific pack, dose schedule or supply duration for this guide.

## Safety

For external lip use only. Not for genital herpes.
