Choose Mupirocin for bacterial skin infections like impetigo, while Polysporin suits minor cuts and scrapes with a higher risk of bacterial contamination.
Here’s a breakdown:
- Active Ingredients: Mupirocin contains mupirocin, an antibiotic. Polysporin typically combines bacitracin and neomycin, both antibiotics. Some Polysporin formulations also include polymyxin B, another antibiotic. Spectrum of Activity: Mupirocin effectively targets Staphylococcus aureus (including methicillin-resistant strains, MRSA in some cases) and Streptococcus pyogenes, common culprits in skin infections. Polysporin’s broader spectrum covers a wider range of bacteria, but increased resistance is a concern. Application: Mupirocin is usually applied topically two to three times daily directly to the infected area. Polysporin is also applied topically, typically a few times a day to the affected skin. Side Effects: Mupirocin generally causes few side effects, but burning or stinging might occur. Polysporin, due to the multiple antibiotics, can cause more allergic reactions, including contact dermatitis. Neomycin allergy is relatively common. Cost: Mupirocin is typically more expensive than Polysporin. Resistance: Mupirocin resistance is developing; however, it is often effective against resistant strains of bacteria when other antibiotics fail. Polysporin, containing multiple antibiotics, faces more rapid resistance development.
Specific Recommendations:
For impetigo or suspected MRSA infection, Mupirocin is often the preferred choice. For minor cuts and abrasions with high risk of mixed bacterial infections, Polysporin may be suitable, unless a known allergy to its components exists. Always consult a healthcare professional for diagnosis and treatment of skin infections. Do not use either ointment for longer than directed, and discontinue use if irritation occurs.
