This medication is used to treat a wide variety of bacterial infections. This medication is a combination of 2 drugs. Piperacillin is a penicillin-type antibiotic that works by stopping the growth of bacteria. Tazobactam is an enzyme inhibitor (beta-lactamase inhibitor) that helps the piperacillin work better.
This medication is given by injection into a vein as directed by your doctor, usually every 6 hours. It should be injected slowly over at least 30 minutes. The dosage is based on your medical condition, age, weight, and response to treatment.
If you are giving this medication to yourself at home, learn all preparation and usage instructions from your health care professional. Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Learn how to store and discard medical supplies safely.
If you are using the frozen pre-mixed solution, thaw the container at room temperature or in the refrigerator. If the bag is thawed in the refrigerator, let it sit at room temperature for at least 1 hour before using. Do no thaw by putting in warm/hot water or microwaving. After thawing, shake well and squeeze the container to check for leaks. Discard solution if the container leaks. Do not re-freeze the solution after thawing.
Antibiotics work best when the amount of medicine in your body is kept at a constant level. Therefore, use this drug at evenly spaced intervals.
Continue to use this medication until the full prescribed amount is finished, even if symptoms disappear after a few days. Stopping the medication too early may allow bacteria to continue to grow, which may result in a return of the infection.
Tell your doctor if your condition persists or worsens.
Swelling, redness, pain, and soreness at the injection site may occur. Dizziness, trouble sleeping, nausea, vomiting, diarrhea, and headache may also occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

This medication may rarely cause a severe intestinal condition (Clostridium difficile-associated diarrhea) due to a type of resistant bacteria. This condition may occur during treatment or weeks to months after treatment has stopped. Tell your doctor right away if you develop: persistent diarrhea, abdominal or stomach pain/cramping, blood/mucus in your stool.
Do not use anti-diarrhea products or narcotic pain medications if you have any of these symptoms because these products may make them worse.
