From the Guidelines

A lip infection with green drainage should be treated with a combination of incision and drainage, and antibiotic treatment, such as clindamycin 300-400 mg four times daily, as recommended by the Infectious Diseases Society of America 1. The presence of green drainage suggests a bacterial infection, which may be caused by Staphylococcus or Streptococcus bacteria.

  • The treatment approach should prioritize incision and drainage, as this is a strong recommendation with high-quality evidence for the management of skin and soft tissue infections, including carbuncles and abscesses 1.
  • Antibiotic treatment should be directed against the suspected causative pathogens, with clindamycin being a suitable option for mild to moderate infections.
  • The dosage and duration of antibiotic treatment should be tailored to the individual patient's needs, with typical regimens lasting 7-10 days.
  • Supportive care measures, such as keeping the area clean, applying warm compresses, and taking over-the-counter pain relievers, can help alleviate symptoms and promote healing.
  • It is essential to seek medical attention promptly, as lip infections can spread quickly and lead to serious complications, particularly in patients with compromised host defenses or systemic inflammatory response syndrome (SIRS) 1.

From the FDA Drug Label

Adults: Serious infections – 150 to 300 mg every 6 hours. More severe infections – 300 to 450 mg every 6 hours The treatment for a lip infection with green drainage may involve antibiotics such as clindamycin. The dosage for serious infections is 150 to 300 mg every 6 hours, and for more severe infections, it is 300 to 450 mg every 6 hours 2.

  • Key considerations: The treatment should be based on the severity of the infection and the clinical judgment of the physician.
  • Important note: Clindamycin should be dosed based on total body weight regardless of obesity.

From the Research

Treatment for Lip Infection with Green Drainage

The treatment for a lip infection with green drainage, which is often a sign of an abscess, typically involves a combination of antibiotic therapy and surgical drainage.

  • The choice of antibiotic depends on the causative agent, with Staphylococcus aureus being a common cause 3, 4, 5.
  • For methicillin-susceptible S. aureus (MSSA) infections, penicillinase-resistant penicillins such as flucloxacillin or dicloxacillin are often used 4.
  • In cases of methicillin-resistant S. aureus (MRSA), vancomycin or teicoplanin may be necessary 4.
  • Surgical drainage is also crucial, especially for necrotic or cavitated lesions, to prevent further complications 3, 5.
  • It is essential to rule out immunosuppression or the presence of MRSA in such cases 3, 5.

Antibiotic Treatment

The specific antibiotic treatment may vary depending on the severity of the infection and the presence of any underlying conditions.

  • For less severe infections, topical antibiotics such as mupirocin or fusidic acid may be sufficient 6.
  • In more severe cases, oral or parenteral antibiotics such as amoxicillin-clavulanate may be necessary 7, 6.
  • The addition of clindamycin to the treatment regimen may be considered in cases of toxinic symptoms or signs 7, 6.

Importance of Prompt Treatment

Prompt diagnosis and treatment are critical to prevent significant complications and ensure a favorable outcome.

  • Delayed treatment can lead to the spread of the infection, causing more severe symptoms and potentially life-threatening conditions 3, 5.
  • Therefore, it is essential to seek medical attention immediately if symptoms of a lip infection with green drainage are present.
