From the Guidelines
For lymphangitis, empiric antibiotic therapy should target Streptococcus and Staphylococcus species, which are the most common causative organisms, with first-line treatment typically being oral dicloxacillin 500 mg four times daily or cephalexin 500 mg four times daily for 7-10 days, as recommended by the Infectious Diseases Society of America 1. The choice of antibiotic should be based on the severity of the infection, patient comorbidities, and local resistance patterns.
- For patients with penicillin allergy, clindamycin 300-450 mg four times daily is an appropriate alternative.
- In cases of severe infection, hospitalization for intravenous antibiotics may be necessary, often using nafcillin, oxacillin, or cefazolin.
- If MRSA is suspected based on local prevalence or risk factors, consider using trimethoprim-sulfamethoxazole, doxycycline, or linezolid. Some key points to consider when treating lymphangitis include:
- The importance of prompt treatment to prevent progression to systemic illness
- The need to adjust treatment based on culture results when available
- The use of supportive measures such as elevating the affected limb, using warm compresses, and monitoring for signs of worsening infection
- The potential for lymphangitis to be caused by a variety of bacterial pathogens, including Streptococcus and Staphylococcus species, and the need to tailor treatment accordingly 1.
From the FDA Drug Label
Adult diabetic patients with clinically documented complicated skin and skin structure infections ("diabetic foot infections") were enrolled in a randomized (2:1 ratio), multi-center, open-label trial comparing study medications administered IV or orally for a total of 14 to 28 days of treatment One group of patients received ZYVOX 600 mg q12h IV or orally; the other group received ampicillin/sulbactam 1. 5 to 3 g IV or amoxicillin/clavulanate 500 to 875 mg every 8 to 12 hours (q8–12h) orally. Patients in the comparator group could also be treated with vancomycin 1 g q12h IV if MRSA was isolated from the foot infection Patients in either treatment group who had Gram-negative bacilli isolated from the infection site could also receive aztreonam 1 to 2 g q8–12h IV.
The antibiotics used to treat lymphangitis are not directly mentioned, but the following antibiotics are used to treat complicated skin and skin structure infections:
- Linezolid
- Ampicillin/sulbactam
- Amoxicillin/clavulanate
- Vancomycin
- Aztreonam 2
From the Research
Antibiotics for Lymphangitis Treatment
- The treatment of lymphangitis, particularly when caused by methicillin-resistant Staphylococcus aureus (MRSA), involves the use of specific antibiotics 3.
- For MRSA infections, including those that may cause lymphangitis, vancomycin, linezolid, and daptomycin are considered effective treatments 4, 5, 6.
- Linezolid is noted for its efficacy in treating complicated skin and soft tissue infections, including those caused by MRSA, and may be preferred due to its superiority in clinical and microbiological success without significant differences in safety compared to other antibiotics like vancomycin and daptomycin 6.
- Other antibiotics such as clindamycin, trimethoprim-sulfamethoxazole, doxycycline, and minocycline may also be used for the treatment of skin and soft tissue infections, including those caused by MRSA, especially in cases where first-line treatments are not suitable 5, 7.
- The choice of antibiotic should be guided by susceptibility patterns and the severity of the infection, with consideration for the potential for resistance development 4, 5, 7.
