Minor skin infections from cuts, scrapes, folliculitis, and insect bites are common, but selecting the right antibiotic or antimicrobial cream makes the difference between a wound that clears in days and one that spreads or becomes chronic. The five creams below cover the full range of OTC and accessible options for managing minor bacterial skin infections, chosen based on antibiotic spectrum, safety profile, and user-reported effectiveness.

Neosporin Original Antibiotic Ointment - Best Broad-Spectrum Wound Infection Prevention
Neosporin combines three antibiotics - neomycin sulfate, polymyxin B, and bacitracin zinc - to cover a wide range of gram-positive and gram-negative bacteria that infect minor skin wounds. The triple-antibiotic formula is more comprehensive than single-ingredient options. The petrolatum base also keeps wounds moist for faster healing. It is the most widely recognized OTC antibiotic ointment and appropriate for minor cuts, scrapes, and post-procedure wound care where polymicrobial contamination is possible. Users sensitive to neomycin should use bacitracin or Polysporin instead.

Bacitracin Zinc Antibiotic Ointment - Best for Sensitivity-Prone Skin
Bacitracin covers the gram-positive organisms most commonly responsible for minor wound infections, including Staphylococcus aureus and Streptococcus pyogenes. Its single-ingredient formula minimizes allergic reaction risk and is the first-choice recommendation when there is a history of contact dermatitis from antibiotic products. The petrolatum base maintains a moist wound environment. It is widely available as a generic at very low cost and is the most appropriate daily wound care antibiotic for minor infected cuts, folliculitis, and abrasions in users with sensitive skin.

Bactroban Mupirocin Cream 2% - Best for Impetigo and Superficial Bacterial Infections
Mupirocin 2% is a prescription antibiotic cream that is the clinical first-line treatment for impetigo, folliculitis, and superficial skin infections caused by Staphylococcus and Streptococcus. It works via a unique mechanism that inhibits bacterial isoleucyl-tRNA synthetase, making cross-resistance with other antibiotic classes essentially non-existent. It is significantly more effective than OTC options for confirmed bacterial skin infections rather than simple contamination prevention. A prescription is required but it is often covered by insurance and available generically at reasonable cost.

Polysporin Antibiotic Ointment - Best Neomycin-Free Broad-Spectrum Cover
Polysporin uses only bacitracin and polymyxin B, omitting neomycin. This gives it a broader gram-negative coverage than plain bacitracin without the 10% contact dermatitis risk associated with neomycin. It is the best OTC alternative for users who want broader coverage than bacitracin alone but have experienced reactions to Neosporin’s triple-antibiotic formula. Polymyxin B is particularly effective against Pseudomonas and other gram-negative organisms that can colonize contaminated or moisture-exposed wounds, making Polysporin a strong choice for water-exposed injuries.

Betadine First Aid Antibacterial Ointment - Best for Contaminated Wounds
Betadine’s first aid ointment uses povidone-iodine as an antiseptic, which provides very broad-spectrum antimicrobial action against bacteria, fungi, and viruses. It is particularly appropriate for visibly contaminated wounds, animal bites, and injuries sustained in dirty environments where the organism profile is unknown. The ointment base maintains wound moisture. Unlike antibiotic ointments, it does not promote antibiotic resistance. However, it should not be used for extended periods as iodine can delay healing in clean wounds if applied beyond the initial cleaning phase.

What to Look For
For clean minor cuts and scrapes, bacitracin or Polysporin prevents the most common infections effectively. For wounds with visible purulence or a spreading redness margin, mupirocin (prescription) is the appropriate step up. Avoid using antibiotic creams preventatively on every minor injury long-term, as this contributes to resistance. Apply antibiotic cream once or twice daily under a sterile dressing, and reassess daily. If the infection is not improving within 48 to 72 hours of antibiotic cream application, seek medical evaluation.
Final Thoughts
Bacitracin is the safest everyday wound-infection cream for most users. Polysporin is the best OTC upgrade when broader coverage is needed without neomycin sensitivity risk. For confirmed bacterial skin infections rather than contamination prevention, a prescription for mupirocin 2% is the most effective path to resolution.
Frequently asked questions
When does a skin infection require a doctor instead of OTC cream?+
See a doctor if the infection shows spreading redness beyond the wound margin, red streaking lines extending outward, increased warmth or swelling, fever, pus that does not clear within 48 hours of antibiotic cream application, or if the infected area is on the face near the eyes. Deep infections, large area involvement, or infections in immunocompromised individuals always require prescription oral antibiotics rather than topical treatment alone.
Is Neosporin or bacitracin better for infected cuts?+
Bacitracin is generally preferred over triple-antibiotic formulas like Neosporin for most minor infected wounds because neomycin, one of Neosporin's three antibiotics, causes contact dermatitis in roughly 10% of users. Bacitracin alone covers the most common wound-infecting bacteria effectively. Neosporin's broader spectrum is beneficial when polymicrobial contamination is suspected, such as in animal bites or heavily contaminated wounds.
Can I use antibiotic cream inside my nose for an MRSA skin infection?+
Mupirocin 2% nasal ointment (Bactroban Nasal) is specifically FDA-indicated for nasal MRSA decolonization and is prescription-only. Regular bacitracin or Neosporin are not appropriate substitutes for MRSA nasal decolonization. For MRSA skin infections on body surfaces, prescription-strength mupirocin 2% cream is the standard of care - OTC creams are insufficient for confirmed MRSA infections and may contribute to antibiotic resistance if used inappropriately.
