Jamy, I don't think tramadol contains codeine, and there's nothing in the literature that shows a contraindication for tramadol if you're allergic to codeine, but you may want to check with a pharmacist to be sure.
Here's a link to the prescription insert published by the manufacturer:

Hope this helps!
Take care,
