No. They are different products from different companies, although both are liquids applied with a swab to a dried mouth ulcer and both labels warn against use with a sulphur allergy. The labels differ on the ingredients, how long the swab is held on the ulcer, whether a repeat application is allowed and what they say about pregnancy and children.

How to read this table
- Each cell restates, in plain words, what that product's own pack or label says. The UlcerMagic column is taken from its pack and the Debacterol column from its label in the United States, so the two come from different countries.
- Their directions differ. Follow the directions on your own pack, never those written for the other product.
Nothing in the table states how strong either liquid is or what it costs, and neither product is judged.
