Do allergic rashes caused by betadine require a particular treatment?

No: Any topical allergic rash, including from beta-dine, needs to be treated with anti-inflammatory medication. Often topical steroids, such as cortisone, are used. Sometimes oral steroids, such as prednisone, are needed if the rash is severe.

Yes: You can react to the iodine or other ingredients. Depending on the severity cold compresses may be adequate. This can be combined with a topical steroid over the counter or prescription.
