1. WHAT PIPERACILLIN/TAZOBACTAM IS AND WHAT IT IS USED FOR
Piperacillin belongs to the group of medicines known as “broad spectrum penicillin antibiotics”. It can kill many kinds of bacteria. Tazobactam can prevent some resistant bacteria from surviving the effects of piperacillin. This means that when piperacillin and tazobactam are given together, more types of bacteria are killed.
Piperacillin/Tazobactam is used in adults and adolescents to treat bacterial infections, such as those affecting the lower respiratory tract (lungs), urinary tract (kidneys and bladder), abdomen, skin or blood. Piperacillin /Tazobactam may be used to treat bacterial infections in patients with low white blood cell counts (reduced resistance to infections).
Piperacillin/Tazobactam is used in children aged 2-12 years to treat infections of the abdomen such as appendicitis, peritonitis (infection of the fluid and lining of the abdominal organs), and gallbladder (biliary) infections.
In certain serious infections, your doctor may consider using Piperacillin/Tazobactam in combination with other antibiotics.
