Exidine is pretty common. Maybe you know it by the name Hibiclens. We always use it to replace iodine when a wet-prep is indicated.
Another name might be DynaHex. May not be the exact same item, but when we have a preference card stating Hibiclens, we substitute DynaHex, which is the solution we stock.
We used to use Technicare for iodine allergies; however, we no longer stock it (if it's even available anymore- we pulled it due to a recall; not sure if that was resolved or not). Now, we use sterile saline if ChloraPrep and betadine are both contraindicated. Not bactericidal, but won't cause an allergic reaction.
We do have a surgeon who doesn't believe in iodine allergies because, well, it is a naturally occurring element that probably can't be avoided, and the allergy isn't to the iodine itself. Instead, he will do a test patch somewhere to see if a reaction occurs.
