Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Raviteja Guddeti, M.B.B.S. [2] Danitza Lukac Vishal Devarkonda, M.B.B.S [3]

Overview

The mainstay of therapy for brucellosis is antimicrobial therapy. The preferred regimen for uncomplicated brucellosis is a combination of Doxycycline and streptomycin. Rifampicin is the drug of choice for brucellosis in pregnancy. For children less than 8 years of age, the preferred regimen is either gentamycin or a combination of trimethoprim-sulfamethoxazole and streptomycin.^[1]

Medical Therapy

The mainstay of therapy for brucellosis is antimicrobial therapy:^[2]^[3]^[4]^[5]^[6]^[7]

Doxycycline and streptomycin are used in combination for 2-3 weeks to prevent recurring infection.
Depending on the timing of treatment and severity of illness, recovery may take a few weeks to several months.
The use of more than one antibiotic is needed for several weeks, due to the fact that the bacteria incubates within cells.

Antimicrobial therapy for Brucellosis
Uncomplicated brucellosis in adults and children ≥8yrs of age	Preferred regimen: Doxycycline 100 mg PO bid for 6 weeks AND Streptomycin 1 g/day IM for 2-3 weeks Alternative regimen (1): Doxycycline 100 mg/day PO for six weeks AND Gentamicin 5mg/kg IM for 7-days Alternative regimen (2): Gentamicin 5mg/kg/day IV/ IM for 7-10 days AND Rifampicin 600–900 mg/day PO for six weeks
Complications of brucellosis	Spondylitis Preferred regimen: Doxycycline for 3 months AND Streptomycin for 2 to 3 weeks. Neurobrucellosis Preferred regimen: Ceftriaxone 2 mg IV q12h for 1 month and Doxycycline 100 mg PO bid for 4-5 month AND Rifampicin 600–900 mg/day PO for 4-5 month Brucella endocarditis Preferred regimen: Doxycyclineaandn Aminoglycoside for at least 8 weeks, and therapy should be continued for several weeks after surgery when valve replacement is necessary Note: Rifampicin or Trimethoprim/sulfamethoxazole are used for their ability to penetrate cell membranes
Pregnancy	Preferred regimen: Rifampicin 900 mg PO qd for 6 weeks Note: Adding Trimethoprim-sulfamethoxazole can be considered, but this option should probably be avoided preceding the 13th week and after the 36th week of gestation because of concern about teratogenicity and kernicterus.
.For children < 8 yrs of age	Preferred regimen (1): TMP/SMZ 8/40 mg/ kg/day PO bid for 6 weeks and Streptomycin 30 mg/kg/day IM q24h for 3 weeks Preferred regimen (2): Gentamicin 5 mg/kg/day IM/ IV q24h for 7-10 days Alternative regimen (1): TMP/SMZAND Rifampicin 15 mg/kg/day PO for 6 weeks Alternative regimen (2): RifampicinAND an Aminoglycoside
.Post-exposure prophylaxis	Preferred regimen (1): Doxycycline 100mg PO bid for at least 3 weeks Preferred regimen (2): TMP/SMZ 160 mg/800mg PO bid for at least 3 weeks
