The reference site for Piperacillin

Piperacillin is a broad-spectrum β-lactam antibiotic of the ureidopenicillin class.

WHAT IS Piperacillin?

Piperacillin is an extended spectrum beta-lactam antibiotic of the ureidopenicillin class. It is normally used together with the beta-lactamase inhibitor tazobactam to form the branded version Tazocin® or Zosyn®(marketed by Wyeth-Ayerst). The combination of these two fights against many gram-positive and gram-negative pathogens and anaerobes, including Pseudomonas aeruginosa.

This combination is mainly used in intensive care medicine (pneumonia, peritonitis), some diabetes-related foot infections and empirical therapy in febrile neutropenia (e.g. after chemotherapy).

Piperacillin and tazobactam are also used to treat many other kinds of infections including those of the skin, blood, central nervous system, respiratory tract, sinuses, urinary tract, and certain infections in women (gynecological infections).

FDA Information

Piperacillin was first approved by the FDA in 1981. Following this, in 1993, the FDA approved the brand name Zosyn® (a combination of piperacillin with tazobactam).

In November 2003, a new generic piperacillin product was FDA-approved. Please visit the official site of the FDA for further information.

What special precautions should I follow?

Tell your doctor or pharmacist if you are allergic to this medication, penicillin, or if you have any other allergies.

Moreover, please inform your doctor if you have pre-existing kidney disease, cystic fibrosis, seizures, or other illnesses.

Piperacillin/tazobactam contains sodium. This could affect you if you are on a salt-restricted diet or if you have a condition which could be worsened by an increase in salt intake (e.g., congestive heart failure). Consult your doctor or pharmacist for more information.

It is important that you also tell your doctor or pharmacist of all prescription and non-prescription/herbal products you may use, especially other antibiotics, “blood thinners”, blood pressure medication, or methotrexate.

Piperacillin/tazobactam may interfere with the effectiveness of birth control pills. Discuss using other methods of birth control with your doctor.

Piperacillin/tazobactam may make you dizzy, so you are strongly advised to use cautiously when engaging in activities requiring alertness such as driving or using machinery. Limit alcoholic beverages.

Kidney function declines as you grow older. This medication is removed by the kidneys, therefore elderly people may be more sensitive to the effects of this drug, especially salt retention.

Piperacillin/tazobactam should be used only if clearly needed during pregnancy. Discuss the risks and benefits with your doctor. Since small amounts of this medication are found in breast milk, consult your doctor before breast-feeding.

Moreover, this medication may rarely cause a severe intestinal condition (pseudomembranous colitis) due to a resistant bacteria. This condition may occur weeks after treatment has stopped.
