1. Contents of the pack and further information

1. What is Piperacillin/Tazobactam Kabi and what is it used for

Piperacillin belongs to a group of medicines called broad-spectrum penicillin antibiotics and can kill many types of bacteria. Tazobactam can prevent some resistant bacteria from surviving the effects of piperacillin. In this way, when piperacillin and tazobactam are administered together, more types of bacteria are killed.

Piperacillin/tazobactam is used in adults and adolescents to treat bacterial infections, such as those affecting the lower respiratory tract (lungs), urinary tract (kidneys and bladder), abdomen, skin, or blood. Piperacillin/tazobactam can be used to treat bacterial infections with low white blood cell counts (reduced resistance to infections).

Piperacillin/tazobactam is used in children between 2 and 12 years of age to treat infections in the abdomen, such as appendicitis, peritonitis (infection of the fluid and lining of the abdominal organs), and infections of the gallbladder. Piperacillin/tazobactam can be used to treat bacterial infections with low white blood cell counts (reduced resistance to infections).

In certain severe infections, your doctor may decide to use Piperacillin/Tazobactam in combination with other antibiotics.

In this case, you must inform your doctor or other healthcare professional immediately.
• if you are taking another antibiotic called vancomycin at the same time as Piperacillin/Tazobactam, this may increase the risk of kidney damage (see also Use of Piperacillin/Tazobactam Kabi with other medicationsin this leaflet).
• if you experience seizures during treatment. In this case, you must inform your doctor or other healthcare professional immediately.
• if you think you have developed a new infection or if your infection has worsened. In this case, you must inform your doctor or other healthcare professional immediately.

Stop using Piperacillin/Tazobactam Kabi and seek immediate medical attention if you notice any of the symptoms described in section 4.

Hemophagocytic lymphohistiocytosis

There have been reports of a disease in which the immune system produces too many white blood cells, called histiocytes and lymphocytes, causing inflammation (hemophagocytic lymphohistiocytosis). This disease can be potentially fatal if not diagnosed and treated early. If you experience multiple symptoms such as fever, swelling of the lymph nodes, feeling of weakness, feeling of dizziness, difficulty breathing, bruising, or skin rash, contact your doctor immediately.

Children under 2 years of age

Piperacillin/tazobactam is not recommended for use in children under 2 years of age due to the lack of safety and efficacy data.

Use of Piperacillin/Tazobactam Kabi with other medications

Tell your doctor or pharmacist that you are using, have recently used, or may need to use any other medication. Some medications may interact with piperacillin or tazobactam.

These include:

• a medication for gout (probenecid). This product may increase the time it takes for piperacillin and tazobactam to be eliminated from the body
• medications used to thin the blood or treat blood clots (e.g., heparin, warfarin, or acetylsalicylic acid).
• medications used to relax muscles during surgery. Inform your doctor if you are going to undergo general anesthesia.
• methotrexate (a medication used to treat cancer, arthritis, or psoriasis). Piperacillin and tazobactam may increase the time it takes for methotrexate to be eliminated from the body.
• medications that decrease potassium levels in the blood (e.g., diuretic pills or certain cancer medications).
• medications containing other antibiotics such as tobramycin, gentamicin, or vancomycin. Inform your doctor if you have kidney problems. Taking Piperacillin/Tazobactam and vancomycin at the same time may increase the risk of kidney damage even if you do not have kidney problems.
