Pharmacist's Verdict

Neosporin is a classic and effective over-the-counter antibiotic ointment for preventing infection in minor cuts, scrapes, and burns, but it's not a miracle healer and can cause allergic reactions in some people.

Ingredient Analysis

Bacitracin Zinc

Neomycin Sulfate

Polymyxin B Sulfate

Pros & Cons

Pros

  • Contains three different antibiotics to kill a wide variety of common skin bacteria.
  • Keeps wounds moist, which can help speed up healing and may reduce scarring.
  • Widely available in almost all drugstores and supermarkets at an affordable price.
  • A long-established, trusted brand for basic first-aid needs.

Cons

  • Allergic reactions (contact dermatitis), most often from the neomycin ingredient, are fairly common and cause redness and itching.
  • Overuse on wounds that are not at high risk for infection can contribute to antibiotic resistance.
  • Should not be used for deep cuts, animal bites, or serious burns; these require a doctor's care.
  • For many minor scrapes, plain petroleum jelly (like Vaseline) can keep a wound moist and protected without the risk of allergy or antibiotic resistance.
