Treatment of Tuberculous Adenitis

Standard Treatment Regimen

The British Thoracic Society recommends that tuberculous adenitis should be treated with the standard 6-month short-course regimen: rifampicin and isoniazid for 6 months, supplemented by pyrazinamide and ethambutol for the first 2 months 1, 2
Administer four drugs daily: rifampicin, isoniazid, pyrazinamide, and ethambutol, for the initial intensive phase 1, 2, 3
Fixed-dose combination tablets should be used whenever possible to improve adherence and prevent accidental monotherapy, which can lead to drug resistance 3, 4
Continue rifampicin and isoniazid daily for an additional 4 months after completing the intensive phase 1, 2, 3

The World Health Organization recommends that children use the same 6-month regimen with weight-adjusted dosing 2, 5
Isoniazid: 5 mg/kg up to maximum 300 mg/day, rifampicin: 10 mg/kg, pyrazinamide: 35 mg/kg, and ethambutol: 15 mg/kg daily 2, 3, 6
Standard treatment should be given to pregnant women with all first-line drugs (rifampicin, isoniazid, pyrazinamide, ethambutol) 1, 2
Patients with liver disease can use all first-line drugs, but baseline and frequent monitoring of liver function is required 1, 2
Patients with diabetes mellitus should use the same standard regimen, but rifampicin reduces the efficacy of sulphonylureas, so doses of oral hypoglycemic agents may need to be increased 1, 2

Directly observed therapy (DOT) should be implemented whenever possible as it is the central element of successful tuberculosis management, although this citation is from a less preferred source, it is included for completeness 9
Do not extend treatment beyond 6 months for uncomplicated tuberculous adenitis, as this is unnecessary and reduces adherence 1, 2
Do not confuse tuberculous adenitis with tuberculous meningitis, which requires 12 months of treatment 1, 2, 5
