- Rash: A skin rash may develop, which could indicate an allergic reaction.
Serious Side Effects (Less Common)

- Clostridium difficile-associated Diarrhea (C. diff): Severe diarrhea can occur after antibiotic use. Contact your doctor if you experience persistent diarrhea.
- Kidney Problems: Signs such as unusual fatigue, swelling in the legs or ankles, or changes in urination may indicate kidney issues.
- Low Blood Cell Counts: Unexplained bruising, bleeding, or frequent infections may suggest a decrease in blood cells.
Contraindications for Piperacillin Tazobactam
A contraindication is a specific condition or factor that makes a medication unsafe for use. Piperacillin-tazobactam has several contraindications, meaning it may not be suitable for everyone.
- Allergy to penicillin or beta-lactam antibiotics: Piperacillin is a penicillin-class antibiotic, and tazobactam is a beta-lactamase inhibitor. If you have a known allergy to penicillin or other beta-lactam antibiotics, taking Piperacillin-tazobactam could trigger a severe allergic reaction, including anaphylaxis, which can be life-threatening.
- Severe renal impairment: In patients with significant kidney problems, the body may not clear Piperacillin-tazobactam effectively, leading to a buildup of the drug in the bloodstream. This can increase the risk of side effects, including seizures and other serious complications.
- History of seizures: Piperacillin-tazobactam can lower the seizure threshold, making seizures more likely in individuals with a history of epilepsy or other seizure disorders.
- Severe liver disease: In patients with severe liver dysfunction, the metabolism and clearance of the medication may be impaired, increasing the risk of toxicity.
Drug to Drug Interactions
Certain medications may interact with Piperacillin-tazobactam, potentially leading to harmful effects or reducing the effectiveness of either drug. If you are taking any of the following, it is important to inform your healthcare provider before starting Piperacillin-tazobactam:
- Probenecid (Benemid): Probenecid can increase the levels of Piperacillin-tazobactam in your blood, which may raise the risk of side effects.
- Vecuronium (Norcuron): Piperacillin-tazobactam may prolong the effects of vecuronium, a muscle relaxant used during surgery, potentially leading to breathing difficulties.
- Methotrexate (Trexall, Rheumatrex): Piperacillin-tazobactam can elevate methotrexate levels, increasing the risk of toxicity, including kidney damage.
- Warfarin (Coumadin): Piperacillin-tazobactam may affect blood clotting, which could increase the risk of bleeding if you are taking blood thinners like warfarin.
