From the Research
Yes, Augmentin (amoxicillin-clavulanate) can be an effective treatment for lymphadenitis, particularly when the infection is caused by susceptible bacteria. The most recent and highest quality study, 1, published in 2020, suggests that lymphadenitis can be treated successfully with empirical antibiotic therapy, and Augmentin is a suitable option. Typical adult dosing is 875 mg amoxicillin/125 mg clavulanate twice daily or 500 mg amoxicillin/125 mg clavulanate three times daily for 7-10 days, depending on the severity of infection. For children, dosing is based on weight, typically 45 mg/kg/day divided into two doses.
- Augmentin works well against many common causes of bacterial lymphadenitis, including Staphylococcus aureus and Streptococcus species, as the clavulanate component helps overcome certain bacterial resistance mechanisms by inhibiting beta-lactamase enzymes.
- However, treatment should be guided by the underlying cause of lymphadenitis, as some cases may be viral, tubercular, or fungal in origin, which would not respond to Augmentin.
- Patients should complete the full course of antibiotics even if symptoms improve quickly, and should seek medical attention if fever persists, lymph nodes continue to enlarge, or if there's increasing redness, warmth, or drainage from the affected area. The study 1 also highlights the importance of considering other potential causes of lymphadenitis, such as melioidosis and actinomycosis, especially in endemic areas. Additionally, the study suggests that aspiration or surgical drainage may be effective in certain patients, and that pathogen isolation and tissue biopsy should be performed to ensure accurate diagnosis and antibiotic selection.
