No, Neosporin and Bacitracin are different. Neosporin is a brand name for a product that contains Bacitricin, polymixin B, and Neomycin as its active ingredients. While Bacitricin is equally a drug brand name, however, it only contains Bacitricin as it’s the only active ingredient. Other differences between these two products are the levels of allergic reaction. While most people have reported of haven suffered allergic reactions after using Neosporin, such is not the case with Bacitracin, which means Neosporin has higher chances of causing allergic reactions.
