Neosporin vs. Polysporin: What's the Difference?

Neosporin and Polysporin are both brand names for topical antibiotic ointments that are used to prevent or treat minor skin infections. Both products contain a combination of antibiotics, but the specific ingredients vary.

Neosporin contains the following antibiotics:

* Neomycin: This antibiotic is effective against a wide range of bacteria, including Staphylococcus aureus and Escherichia coli.

* Polymyxin B: This antibiotic is also effective against a wide range of bacteria, including Pseudomonas aeruginosa.

* Bacitracin: This antibiotic is effective against a variety of Gram-positive bacteria, including Streptococcus pyogenes.

Polysporin contains the following antibiotics:

* Polymyxin B: This antibiotic is also effective against a wide range of bacteria, including Pseudomonas aeruginosa.

* Bacitracin: This antibiotic is effective against a variety of Gram-positive bacteria, including Streptococcus pyogenes.

In general, Neosporin is considered to be more effective than Polysporin because it contains neomycin, which is a broader-spectrum antibiotic. However, Polysporin may be a better choice for people who are allergic to neomycin or who have a history of kidney disease.

It is important to note that both Neosporin and Polysporin are only available over-the-counter in the United States. If you have a serious skin infection, you should see a doctor for prescription antibiotics.
