Piperacillin — Uses, Dosage, Side Effects & Safety

Drug class: Infection & Antibiotics

Overview

Piperacillin is a prescription antibiotic used to treat a wide range of serious bacterial infections, including those of the lungs (such as pneumonia), urinary tract, skin, abdomen, and blood (sepsis). It is especially effective against infections caused by susceptible Gram-negative and Gram-positive bacteria, including Pseudomonas aeruginosa. Piperacillin works by interfering with the formation of bacterial cell walls, which leads to the destruction of the bacteria. It is often given in combination with tazobactam, a beta-lactamase inhibitor, to broaden its spectrum and overcome resistance. Key points for patients: Piperacillin is usually administered by injection in a hospital or clinic setting. It is important to complete the full course of therapy as prescribed, even if you start to feel better, to ensure the infection is fully treated and to prevent resistance.
