1. What Piperacilin/Tazobactam Aurovitas is and what it is used for

Piperacillin belongs to a group of medicines called "broad-spectrum penicillin antibiotics" and can destroy many types of bacteria. Tazobactam can prevent some resistant bacteria from surviving the effects of piperacillin. Thus, when piperacillin and tazobactam are administered concomitantly, a wider range of bacteria are destroyed.

Antibiotics are used to treat bacterial infections and are not effective against viral infections such as flu or the common cold.

It is important that you follow the instructions regarding dose, dosing interval, and duration of treatment as directed by your doctor.

Do not store or reuse this medicine. If you have any antibiotic left over after completing your treatment, return it to the pharmacy for proper disposal. Medicines must not be disposed of down the drain or in household waste.

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 may be used to treat bacterial infections in patients 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 abdominal infections, such as appendicitis, peritonitis (infection of the fluid and lining of abdominal organs), and infections of the gallbladder. Piperacillin/tazobactam may be used to treat bacterial infections in patients with low white blood cell counts (reduced resistance to infections).

In certain severe infections, your doctor may consider using piperacillin/tazobactam in combination with other antibiotics.

2. What you need to know before using Piperacillin/Tazobactam Aurovitas

Do not use Piperacillin/Tazobactam Aurovitas

• if you are allergic to piperacillin, tazobactam, or any of the other ingredients of this medicine (listed in section 6).
• if you are allergic to antibiotics known as penicillins, cephalosporins, or other beta-lactamase inhibitors, as you may be allergic to piperacillin/tazobactam.

Warnings and precautions

Talk to your doctor, pharmacist, or nurse before using Piperacillin/Tazobactam Aurovitas:

• if you have allergies. If you have multiple allergies, make sure to inform your doctor or other healthcare professional before receiving this medicine.
• if you had diarrhea before treatment or if you develop diarrhea during or after treatment. In this case, inform your doctor or other healthcare professional immediately. Do not take any medication for diarrhea without first consulting your doctor.
• if you have low blood potassium levels. Your doctor may want to assess your kidney function before you receive this medicine and may perform periodic blood tests during treatment.
• if you have kidney or liver problems, or are undergoing hemodialysis. Your doctor may want to check your kidney function before you receive this medicine and may perform periodic blood tests during treatment.
• if you are taking another antibiotic called vancomycin at the same time as piperacillin/tazobactam, as this may increase the risk of kidney damage (see also Other medicines and Piperacillin/Tazobactam Aurovitas in this leaflet).
• if you are taking certain medicines (called anticoagulants) to prevent excessive blood clotting (see also Other medicines and Piperacillin/Tazobactam Aurovitas in this leaflet) or if you experience unexpected bleeding during treatment. In this case, inform your doctor or other healthcare professional immediately.
• if you experience seizures during treatment. In this case, inform your doctor or other healthcare professional immediately.
• if you suspect you have developed a new infection or if your infection has worsened. In this case, inform your doctor or other healthcare professional immediately.

Haemophagocytic lymphohistiocytosis

Cases of a disease in which the immune system produces excessive numbers of otherwise normal white blood cells called histiocytes and lymphocytes, leading to inflammation (haemophagocytic lymphohistiocytosis), have been reported. This condition can be potentially fatal if not diagnosed and treated early. If you experience multiple symptoms such as fever, swollen lymph nodes, feeling weak, 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 limited data on safety and efficacy.

Other medicines and Piperacillin/Tazobactam Aurovitas

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines, including those obtained without a prescription.

Some medicines may interact with piperacillin or tazobactam. These include:

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

Effects on laboratory tests

If you need to provide a blood or urine sample, inform your doctor or laboratory staff that you are taking piperacillin/tazobactam.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine. Your doctor will decide whether piperacillin/tazobactam is suitable for you.

Piperacillin and tazobactam may pass to the unborn baby through the placenta or into breast milk. If you are breastfeeding, your doctor will decide whether piperacillin/tazobactam is suitable for you.

Driving and using machines

Piperacillin/tazobactam is not expected to affect your ability to drive or operate machinery.

Piperacillin/Tazobactam Aurovitas contains sodium

This medicine contains 216 mg of sodium (the main component of table/cooking salt) per vial. This corresponds to 10.8% of the maximum daily recommended sodium intake for an adult. This should be taken into account in patients on a low-sodium diet.

3. How to use Piperacillin/Tazobactam Aurovitas

Your doctor or another healthcare professional will administer this medicine by intravenous infusion (into a vein via an infusion drip over 30 minutes).

Dosage

The dose of medicine you will be given depends on what you are being treated for, your age, and whether or not you have kidney problems.

Adults and adolescents aged 12 years and older

The usual dose is 4 g/0.5 g of piperacillin/tazobactam administered every 6–8 hours intravenously (directly into the bloodstream).

Children aged 2 to 12 years

The usual dose for children with abdominal infections is 100 mg/12.5 mg/kg body weight of piperacillin/tazobactam administered every 8 hours intravenously (directly into the bloodstream). The usual dose for children with low white blood cell counts is 80 mg/10 mg/kg body weight of piperacillin/tazobactam administered every 6 hours intravenously (directly into the bloodstream).

Your doctor will calculate the dose based on the child's body weight, but each individual dose will not exceed 4 g/0.5 g of piperacillin/tazobactam.

You will be given piperacillin/tazobactam until all signs of infection have completely disappeared (from 5 to 14 days).

Patients with kidney problems

Your doctor may need to reduce your dose of piperacillin/tazobactam or the frequency of administration. Your doctor may also wish to carry out blood tests to ensure you are receiving the correct dose, especially if you need to use this medicine for a prolonged period.

If you use more Piperacillin/Tazobactam Aurovitas than you should

Since piperacillin/tazobactam will be administered by a doctor or another healthcare professional, it is unlikely that you will receive an incorrect dose. However, if you experience adverse effects such as seizures, or think you have been given too much medicine, tell your doctor immediately.

In case of overdose or accidental ingestion, contact your doctor or pharmacist immediately or call the Toxicology Information Service at 91 562 04 20, indicating the medicine and the amount administered.
