Piperacillin + Tazobactam: Brands, Price & Uses in Bangladesh

Piperacillin + Tazobactam is an injectable combination antibiotic (an extended-spectrum penicillin plus a beta-lactamase inhibitor) used to treat serious bacterial infections caused by susceptible, including beta-lactamase-producing, organisms.

Established / FDA-approved uses

• Complicated intra-abdominal infections (e.g. appendicitis with peritonitis, peritonitis), typically with an antibacterial active against anaerobes when clinically indicated
• Complicated and uncomplicated skin and skin structure infections, including diabetic foot infections
• Community-acquired pneumonia (moderate severity)
• Nosocomial (hospital-acquired) pneumonia, moderate to severe, generally used together with an aminoglycoside
• Postpartum endometritis and other pelvic infections

Guideline-supported / adjunct uses

• Empiric therapy of febrile neutropenia, usually in combination with an aminoglycoside, as recommended by infectious disease guidelines
• Empiric broad-spectrum coverage in sepsis of unknown source pending culture results, per local antibiogram and specialist guidance

The final choice of antibiotic and duration of therapy should be guided by culture and sensitivity results and a physician's clinical judgment.

Piperacillin + Tazobactam is given only by intravenous infusion, usually over 30 minutes (extended infusions of 3–4 hours may be used in some hospital protocols for severe infections, per local practice). Dose and frequency depend on the indication, severity of infection, and renal function.

Renal impairment

Dose and/or frequency must be reduced according to creatinine clearance (CrCl), as advised by the treating physician; patients on hemodialysis require an additional dose after each dialysis session.

Antibiotic stewardship

Take exactly as prescribed by your physician; do not stop, extend, skip doses, or share this medicine with others without medical advice. Completing the full prescribed course helps prevent treatment failure and antibiotic resistance.

Most people tolerate Piperacillin + Tazobactam well, but side effects can occur.

Common

• Diarrhea, nausea, vomiting, constipation
• Headache, insomnia
• Rash, itching
• Injection/infusion site reactions
• Mildly elevated liver enzymes

Less common but important

• Hypersensitivity reactions, including rash, fever, and rarely anaphylaxis (see Contraindications)
• Electrolyte disturbances, particularly low potassium (hypokalemia), related to the sodium content of the formulation
• Clostridioides difficile-associated diarrhea/colitis, which can range from mild to severe and may occur even after the medicine is stopped
• Blood count changes (e.g. low white cell or platelet counts)

Seek prompt medical attention for severe rash, difficulty breathing, swelling of the face/throat, severe or persistent diarrhea, or unusual bleeding/bruising.
