I have been putting polysporin (bacitracin and polymyxin) on a burn for the past 3-4 days. Just realized it expired in 2007/2008. Is this in any way dangerous?

Polysporin (bacitracin and polymyxin): The outdated polysporin (bacitracin and polymyxin) will not hurt you and will be fine to use. Many expiration dates are not scientifically valid. Think of it as an expiration date on a bar of soap.
