1. What is Piperacillin/Tazobactam Sala 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 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 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 (reduced resistance to infections).

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

2. What you need to know before you use Piperacillin/Tazobactam Sala

Do not use Piperacillin/Tazobactam Sala

• if you have kidney or liver problems, or if you are undergoing hemodialysis. Your doctor may want to examine your kidneys before you receive this medicine and may perform periodic blood tests during treatment.
• if you are using 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 Sala” in this leaflet).
• if you are using certain medicines (called anticoagulants) to prevent excessive blood clotting (see also “Other medicines and Piperacillin/Tazobactam Sala” in this leaflet) or if you experience unexpected bleeding during treatment.

• 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.
• 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 of age due to the lack of safety and efficacy data.

Other medicines and Piperacillin/Tazobactam Sala

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 product 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. Inform your doctor if you have kidney problems, even if you do not 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.

The usual 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 of age

The usual 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.

Instructions for Use

Piperacillin/Tazobactam will be administered by intravenous infusion (drip over 30 minutes).

Intravenous Route

Each vial should be reconstituted with the volume of solvent shown in the following table, using one of the compatible solvents for reconstitution. To facilitate vial reconstitution, invert and shake to release the powder adhered to the walls. Shake with rotary movements until dissolved. If shaken constantly, it usually reconstitutes within 5 to 10 minutes (see handling details below).

• Compatible solvents for reconstitution:
  • Sodium chloride injection solution 0.9% (9 mg/ml)
  • Sterile water for injectable preparations (1)
  • 5% Glucose

(1) The maximum recommended volume of sterile water for injectable preparations per dose is 50 ml.

The reconstituted solutions should be extracted from the vial with a syringe. After reconstitution as indicated, the vial content extracted with a syringe will provide the nominal amount of piperacillin and tazobactam.

The reconstituted solutions can be further diluted to the desired volume (e.g., from 50 ml to 150 ml) with one of the following compatible solvents:

• Sodium chloride injection solution 0.9% (9 mg/ml)
• 5% Glucose
• 6% Dextran in sodium chloride 0.9%

Incompatibilities

Whenever Piperacillin/Tazobactam is used simultaneously with another antibiotic (e.g., aminoglycosides), these should be administered separately. The mixture of beta-lactam antibiotics with aminoglycosides in vitrocan result in substantial inactivation of the aminoglycoside.

Piperacillin/Tazobactam should not be mixed with other substances in a syringe or infusion bottle, as its compatibility has not been established.

Due to chemical instability, Piperacillin/Tazobactam should not be used with solutions containing only sodium bicarbonate.

Piperacillin/Tazobactam is not compatible with Ringer's lactate solution (sodium chloride composite solution).

Piperacillin/Tazobactam should not be added to hemoderivatives or albumin hydrolysates.
