1. What is Piperacillin + Tazobactam Accord and what is it used for

Piperacillin belongs to a group of medicines called "broad-spectrum penicillins". It is an antibiotic that kills many types of bacteria. Tazobactam may prevent some bacteria that are not sensitive to piperacillin from surviving. This means that when piperacillin and tazobactam are given together, more strains of bacteria will be killed. Piperacillin + Tazobactam Accord is used in adults and adolescents to treat bacterial infections of the lower respiratory tract (lungs), urinary tract (kidneys and bladder), abdominal cavity, skin, and blood. Piperacillin + Tazobactam Accord may be used to treat bacterial infections in patients with a low white blood cell count (reduced resistance to infections). Piperacillin + Tazobactam Accord is used in children aged 2 to 12 years to treat infections in the abdominal cavity, including appendicitis, peritonitis (infection of the fluid and membrane inside the abdominal organs), and cholecystitis (bile ducts). Piperacillin + Tazobactam Accord can be used to treat bacterial infections in patients with a low white blood cell count (reduced resistance to infections). In some severe infections, the doctor may consider giving Piperacillin + Tazobactam Accord together with other antibiotics.

2. Important information before using Piperacillin + Tazobactam Accord

When not to use Piperacillin + Tazobactam Accord

• If the patient is allergic to piperacillin or tazobactam.
• If the patient is allergic to antibiotics called penicillins, cephalosporins, or other beta-lactamase inhibitors, as they may be allergic to Piperacillin + Tazobactam Accord.

Warnings and precautions

Before starting treatment with Piperacillin + Tazobactam Accord, the patient should discuss with their doctor, pharmacist, or nurse:

• If the patient has allergies. If the patient has multiple allergies, they should make sure to tell their doctor or healthcare professional about them before taking the medicine.
• If the patient has had diarrhea before treatment or if it occurs during or after treatment. The patient should immediately inform their doctor or healthcare professional about this. The patient should not take any medicines for diarrhea without consulting their doctor.
• If the patient has low potassium levels in their blood. It is possible that the doctor will check the patient's kidneys and perform regular blood tests during treatment.
• If the patient has kidney or liver problems, or is undergoing hemodialysis. It is possible that the doctor will check the patient's kidneys and perform regular blood tests during treatment.
• If the patient is taking another antibiotic called vancomycin at the same time as Piperacillin + Tazobactam Accord, as the risk of kidney damage may be increased (see also Piperacillin + Tazobactam Accord and other medicines in this leaflet).
• If the patient is taking certain medicines (called anticoagulants) that prevent excessive blood clotting (see also Piperacillin + Tazobactam Accord and other medicines in this leaflet) or if unexpected bleeding occurs during treatment. The patient should immediately tell their doctor or healthcare professional about this.
• If the patient experiences seizures during treatment. The patient should immediately tell their doctor or healthcare professional about this.
• If the patient thinks they have developed a new infection or if an existing infection has worsened. In this case, the patient should tell their doctor or healthcare professional about it.

There have been reports of a disease in which the immune system produces too many normally harmless white blood cells called histiocytes and lymphocytes, causing inflammation (hemophagocytic lymphohistiocytosis). This condition can be life-threatening if not diagnosed and treated early. If the patient experiences multiple symptoms such as fever, swollen lymph nodes, feeling weak, dizziness, shortness of breath, bluish discoloration, or skin rash, they should immediately contact their doctor.

Children

Piperacillin + Tazobactam Accord is not recommended for use in children under 2 years of age due to insufficient data on safety and efficacy.

Piperacillin + Tazobactam Accord and other medicines

The patient should tell their doctor or healthcare professional about all medicines they are currently taking, or have recently taken, and about any medicines they plan to take, including those available without a prescription. Some medicines may interact with piperacillin and tazobactam. These include:

• A medicine used to treat gout (probenecid). It may prolong the time it takes for piperacillin and tazobactam to be removed from the body.
• Medicines that reduce blood clotting or are used to treat blood clots (e.g., heparin, warfarin, aspirin).
• Medicines used to relax muscles during surgery. If the patient is to undergo general anesthesia, they should inform their doctor about taking this medicine.
• Methotrexate (a medicine used to treat cancer, arthritis, or psoriasis). Piperacillin and tazobactam may prolong the time it takes for methotrexate to be removed from the body.
• Medicines that reduce potassium levels in the blood (e.g., diuretics or certain medicines used to treat cancer).
• Medicines containing other antibiotics: tobramycin, gentamicin, or vancomycin. If the patient has kidney problems, they should tell their doctor. Taking Piperacillin + Tazobactam Accord and vancomycin at the same time may increase the risk of kidney damage, even if the patient does not have kidney problems.

If the patient is going to have a blood or urine test, they should tell their doctor or laboratory staff that they are taking Piperacillin + Tazobactam Accord.

Pregnancy and breastfeeding

If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a baby, they should consult their doctor or healthcare professional before taking this medicine. The doctor will decide whether Piperacillin + Tazobactam Accord is suitable for the patient. Piperacillin and tazobactam may pass into the baby in the womb or through breast milk. If the patient is breastfeeding, the doctor will decide whether Piperacillin + Tazobactam Accord is suitable for them.

Driving and using machines

Taking Piperacillin + Tazobactam Accord is unlikely to affect the patient's ability to drive or use machines.

3. How to use Piperacillin + Tazobactam Accord

This medicine will be given to the patient by a doctor or other healthcare professional through an intravenous infusion (lasting 30 minutes) into one of the patient's veins.

Dosage

The dose of the medicine given to the patient depends on the disease being treated, the patient's age, and any kidney problems they may have.

Adults and adolescents over 12 years

The usual dose is 4 g of piperacillin and 0.5 g of tazobactam, given into one of the patient's veins (directly into the bloodstream) every 6-8 hours.

Children aged 2 to 12 years

In children with abdominal infections, the recommended dose is 100 mg of piperacillin and 12.5 mg of tazobactam per kilogram of body weight, given into one of the patient's veins (directly into the bloodstream) every 8 hours. The usual dose in children with a low white blood cell count is 80 mg of piperacillin and 10 mg of tazobactam per kilogram of body weight, given into one of the patient's veins (directly into the bloodstream) every 6 hours. The doctor will calculate the dose of the medicine based on the child's body weight, but each individual dose of Piperacillin + Tazobactam Accord will not exceed 4 g + 0.5 g. The patient will receive Piperacillin + Tazobactam Accord until the infection symptoms have completely resolved (for 5 to 14 days).

Patients with kidney problems

The doctor may recommend reducing the dose of Piperacillin + Tazobactam Accord or the frequency of administration. It is possible that the doctor will perform blood tests to ensure that the correct dose of the medicine is being given, especially if the patient is receiving the medicine for a long time.

Overdose of Piperacillin + Tazobactam Accord

Piperacillin + Tazobactam Accord will be given to the patient by a doctor or other healthcare professional, so it is unlikely that the wrong dose will be given.
