Is polysporin and neosporin the same thing?

Can staph infections cause an allergy to neosporin or polysporin?

• My husband and I have both recently had staph infections and (this time) both been to the dermatologist for them. My dermatologist told me to use polysporin for mine, and then surrounding areas started getting itchy. When I went back, he told me I was allergic to polysporin and therefore also allergic to neosporin. My husband used polysporin and neosporin on his at different times, and the dermatologist told him he was now allergic to neosporin because of what happened. Both of us have used neosporin all of our lives. Why are we both suddenly allergic to it? Could the staph that is probably living in us, and may have been for 2 years, (till we can get rid of it permanently) have caused us to become allergic to polysporin/neosporin? Also, is there any chance that we're not permanently allergic to polysporin/neosporin?

• Answer:

  See your doctor on this one. Doesn't sound plausible to me, though.
