Quick overview

Tazocin Injection is a broad-spectrum, combination antibiotic containing piperacillin sodium (a penicillin antibiotic) and tazobactam sodium (a beta-lactamase inhibitor). It is given intravenously, mainly in hospital settings, to treat moderate-to-severe bacterial infections. It is not effective against viral infections such as the common cold or flu.

What is Tazocin Injection

Tazocin Injection is a broad-spectrum, combination antibiotic containing two active ingredients: piperacillin (a penicillin antibiotic) and tazobactam (a beta-lactamase inhibitor). It is a powerful intravenous medication used primarily in hospital settings to treat moderate-to-severe bacterial infections. It is ineffective against viral infections like the cold or flu.

Tazocin Injection uses

  • Severe lung infections, such as hospital-acquired or community-acquired pneumonia
  • Abdominal infections, including complicated stomach infections, peritonitis, or gallbladder infections
  • Skin and soft tissue infections, such as deep tissue cellulitis, diabetic foot ulcers, or abscesses
  • Urinary tract infections (UTIs), specifically complicated UTIs or kidney infections
  • Gynecological infections, such as severe postpartum or pelvic infections
  • Sepsis and bacteremia (severe bloodstream infections)
  • Febrile neutropenia (used as empiric treatment for patients with low white blood cell counts who develop a fever)

Benefits of Tazocin Injection

  • Overcomes bacterial resistance by blocking the enzyme (beta-lactamase) that some bacteria use to destroy penicillin
  • Broad spectrum action against Gram-positive, Gram-negative, and anaerobic bacteria
  • Effective for mixed infections caused by multiple types of bacteria at once, commonly found in the abdomen

How Tazocin Injection works

Piperacillin kills bacteria by stopping them from building their cell walls. Tazobactam blocks an enzyme that bacteria use to destroy piperacillin, so the combination works against more types of bacteria than piperacillin alone.

Tazocin Injection dosage

This medicine is given into a vein (intravenously) either as a slow injection or a slow infusion over a set period of time. It is given at regular intervals throughout the day as directed by your doctor. The length of treatment depends on your general health, the type of infection you have, and how well you respond to the medication. You may receive it in a hospital, or you may be shown how to give it to yourself at home. After your condition improves, your doctor may switch you to another antibiotic you can take by mouth to finish your treatment. You should begin to feel better during the first few days of treatment; call your doctor if your symptoms do not improve or get worse. Antibiotics will not work for colds, flu, or other viral infections.

Warnings and precautions

  • Pregnancy: There is not enough human study data on using this medicine during pregnancy. 
  • Pregnant women should be treated only if the expected benefit outweighs the possible risks to the mother and baby.
  • Breastfeeding: There is not enough study data on using this medicine while breastfeeding. 
  • Breastfeeding women should be treated only if the expected benefit outweighs the possible risks to the woman and child.
  • Kidney: People with kidney problems need their dose adjusted based on how well their kidneys are working, and should tell their doctor about any kidney disease.
  • Liver: Using this medicine together with a beta-lactamase inhibitor may slightly increase the risk of liver-related side effects, and liver function should be kept in mind during treatment.
  • Do not use this medicine if you have a history of severe allergic reactions to penicillins, cephalosporins, or beta-lactamase inhibitors, or any of its ingredients.
  • Serious and sometimes fatal allergic reactions have happened in patients taking penicillin or cephalosporin antibiotics, including this medicine.
  • This medicine may cause severe skin reactions such as Stevens-Johnson syndrome and other serious skin conditions. 
  • If a skin rash develops, patients should be watched closely and the medicine stopped if the rash gets worse.
  • Antibiotic-related colitis caused by C. difficile bacteria can occur, ranging from mild to life-threatening, and may appear even weeks after stopping the antibiotic.
  • Low white blood cell counts can occur, especially with prolonged treatment, so regular blood tests are recommended.
  • Seizures can occur, especially with high doses or in people with kidney problems.
  • This medicine may make hormonal birth control (pills, patches, rings, injections) less effective, so another method of contraception should be used during treatment.
  • Tell your doctor if you have cystic fibrosis, as this can increase the risk of fever and rash with this medicine.
  • Bleeding problems have occurred in some patients taking piperacillin, more often in those with kidney failure.
  • If you have diabetes, this medicine can cause false results with certain urine glucose tests, so talk to your doctor about alternative testing.

Storage

  • Vials containing sterile powder for injection should be stored at controlled room temperature (15°C - 25°C) in the original container

  • Keep all medication out of sight and reach of children

When to see a doctor

  • Seek immediate medical attention for signs of a severe allergic reaction, including facial or throat swelling and difficulty breathing.
  • Seek medical help if you notice a marked decrease in urination or swelling in the feet and ankles, which may signal kidney injury.
