From the Guidelines
The best treatment for a lip infection typically involves topical antibiotics like Polysporin (bacitracin/neomycin), which can be applied to the affected area 2-3 times daily for 7-10 days, as recommended by recent guidelines 1. When treating a lip infection, it's essential to consider the cause of the infection, which is often bacterial, and the most effective treatment options.
- Before applying any topical antibiotic, gently clean the infected area with mild soap and water, then pat dry.
- Apply a thin layer of the ointment directly to the infection using a clean cotton swab or fingertip.
- Polysporin works by killing bacteria that cause infection while creating a protective barrier over the wound. Some key points to consider when treating lip infections include:
- For more severe infections with significant swelling, redness, pain, or if the infection doesn't improve within 2-3 days, oral antibiotics prescribed by a healthcare provider may be necessary 1.
- While using topical antibiotics, avoid picking at the area, maintain good oral hygiene, stay hydrated, and consider taking an over-the-counter pain reliever like acetaminophen or ibuprofen if discomfort persists.
- If you have a history of allergic reactions to either bacitracin or neomycin, use an alternative antibiotic ointment like Bacitracin alone or consult with a healthcare provider for recommendations. It's also important to note that the majority of superficial skin and soft-tissue infections, including lip infections, are caused by Gram-positive bacteria, particularly streptococci and S. aureus, and should be managed with antibiotic therapy against these pathogens 1.
From the Research
Treatment Options for Lip Infections
- Lip infections can be caused by various bacteria, including Staphylococcus aureus, and may require antibiotic treatment or surgical intervention 2.
- The use of topical antibiotics, such as bacitracin and neomycin, found in Polysporin, may be effective in preventing infections in minor skin trauma, including lip infections 3.
Efficacy of Polysporin
- Triple-antibiotic ointment, which contains neomycin, polymyxin B, and bacitracin, has been shown to be safe and effective in preventing infections in minor skin trauma 3.
- A study found that a topical antimicrobial gel containing cetrimide, bacitracin, and polymyxin B sulfate reduced the incidence of clinical infections in minor accidental wounds 4.
Considerations for Treatment
- The treatment of lip infections should consider the cause of the infection, as well as the patient's immune status and potential antibiotic resistance 2.
- Topical antibiotics, such as Polysporin, may be a suitable option for minor lip infections, but more severe infections may require oral or intravenous antibiotics, or surgical intervention 2, 3.
