1. What is Piperacillin/Tazobactam Aurovitas 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, by administering piperacillin and tazobactam concomitantly, more types of bacteria are destroyed.

Antibiotics are used to treat bacterial infections and do not work for viral infections such as the flu or the common cold.

It is essential that you follow the instructions regarding dosage, administration interval, and treatment duration indicated by your doctor.

Do not store or reuse this medicine. If you have any leftover antibiotic after finishing treatment, return it to the pharmacy for proper disposal. Do not throw medicines down the drain or into the trash.

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 in patients with low white blood cell counts (lower resistance to infections).

Piperacillin/tazobactam is used in children between 2 and 12 years old 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 in patients with low white blood cell counts (lower 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 you use Piperacillin/Tazobactam Aurovitas

Do not use Piperacillin/Tazobactam Aurovitas

• if you are using another antibiotic called vancomycin at the same time as piperacillin/tazobactam, it may increase the risk of kidney damage (see also Other medicines and Piperacillin/Tazobactam Aurovitas in this leaflet).
• if you are using 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.

Hemophagocytic lymphohistiocytosis

There have been reports of a disease in which the immune system produces too many white blood cells, otherwise normal, 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

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

Other medicines and Piperacillin/Tazobactam Aurovitas

Tell your doctor or pharmacist if you are using, have recently used, or might use 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 going to undergo 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 decrease potassium levels in the blood (e.g., diuretic pills or certain cancer medicines).
• medicines that contain other antibiotics such as tobramycin, gentamicin, or vancomycin.
• Tell your doctor if you have kidney problems. The use of piperacillin/tazobactam and vancomycin at the same time may increase the risk of kidney damage, even if you do not have kidney problems.

3. How to use Piperacillin/Tazobactam Aurovitas

Your doctor or other healthcare professional will administer this medicine to you by intravenous infusion (into a vein with a drip over 30 minutes).

Dosage

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

Adults and adolescents 12 years and older

The normal dose is 4 g/0.5 g of piperacillin/tazobactam administered every 6-8 hours through a vein (directly into the bloodstream).

Children 2 to 12 years old

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

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

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

Patients with kidney problems

It may be necessary for your doctor to reduce the dose of piperacillin/tazobactam or the frequency of administration. Your doctor may also want to perform blood tests to ensure you are receiving the correct dose of treatment, especially if you need to use this medicine for a long time.

If you use more Piperacillin/Tazobactam Aurovitas than you should

Because a doctor or other healthcare professional will administer piperacillin/tazobactam to you, it is unlikely that you will receive an incorrect dose. However, if you experience side effects such as seizures or think you have been given too much medicine, tell your doctor immediately.
