Antibacterial combination (Penicillin-class antibiotic and beta-lactamase inhibitor)

TAZOBACTAM (often used in combination with piperacillin) is an injectable medication used to treat serious bacterial infections. It works by combining an antibiotic with a substance that helps overcome bacterial resistance.

How it worksThis drug works as a beta-lactamase inhibitor, which means it helps stop bacteria from breaking down the antibiotic, making the treatment more effective.

Brand names:Piperacillin and Tazobactam

Used for

Intra-abdominal infections in adults and children (2 months and older)Hospital-acquired pneumonia in adults and children (2 months and older)Skin and skin structure infections in adultsPelvic infections in adult femalesCommunity-acquired pneumonia in adults

How to take

FormsInjection

RoutesIntravenous (IV)

Adult dosages vary by condition. For most infections, the dose is 3.375 g every six hours. For hospital-acquired pneumonia, the starting dose may be higher at 4.5 g every six hours combined with another medication. Patients with kidney issues will need a lower dose.

This medication should only be used to treat or prevent infections that are proven or strongly suspected to be caused by bacteria to avoid drug resistance. Dosage must be adjusted for patients with kidney impairment or those on dialysis.

Special populations

PregnancyTAZOBACTAM can cross the placenta. While animal studies showed no major birth defects at certain doses, there is not enough information from pregnant women to fully know the risks to a developing baby.

PediatricTAZOBACTAM is used in children 2 months of age and older for certain infections like intra-abdominal infections and hospital-acquired pneumonia.

GeriatricPatients over 65 may need lower doses, especially if they have decreased kidney, liver, or heart function. This medication also contains sodium, which may be important for elderly patients to monitor.
