What TAZOCIN EF is used for
The name of your medicine is TAZOCIN EF. It contains the active ingredients piperacillin sodium and tazobactam sodium. They belong to a group of antibiotics called penicillins that work by killing bacteria.
Piperacillin is an antibiotic that kills many types of bacteria. Tazobactam belongs in the penicillin group but does not have activity against bacteria. It helps piperacillin to overcome bacteria which have become resistant to piperacillin.
TAZOCIN EF is active against bacteria which cause serious infections such as: –
- Chest infections
- Urine infections
- Stomach infections
- Skin infections
- Gynaecological infections
- Septicaemia (blood poisoning).
It is also used to treat many other infections.
In hospitalised children aged 2 to 12 years, TAZOCIN EF is used to treat serious infections in the abdomen.TAZOCIN EF is not recommended to treat abdominal infections in children under 2 years.
TAZOCIN EF will not work against infections caused by viruses such as colds or flu.
This medicine is available only with a doctor's prescription.
TAZOCIN EF is not addictive.

How TAZOCIN EF will be given to you
How much you will be given
The dosage of TAZOCIN EF is generally 4.5g every eight hours. The dose may vary between 2.25g and 4.5 g and may also be given every six hours. For children aged 2 to 12 years, weighing up to 40 kg, and with normal kidney function, the recommended dosage is 112.5 mg/kg (100 mg piperacillin/12.5 mg tazobactam) every 8 hours. For children aged 2 to 12 years, weighing over 40 kg, and with normal kidney function, the recommended dose is 4.5 g (4 g piperacillin/0.5 g tazobactam) every 8 hours.
Your doctor may change these dosages.
If you have kidney disease your doctor will adjust the dose to suit you.
How TAZOCIN EF will be given
A doctor or nurse in hospital will always give TAZOCIN EF to you. It will usually be given to you as a slow injection into a vein over 20-30 minutes.
How long you will receive TAZOCIN EF
The length of time you will be given TAZOCIN EF depends on the type and severity of your infection. It should be given for at least five days, and for 48 hours after all signs of illness and fever have gone.
It is unlikely that you will ever receive an overdose of TAZOCIN EF because it will be given by a trained nurse or doctor.
While you are receiving TAZOCIN EF
If you receive TAZOCIN EF for a prolonged time, your doctor may wish to do some blood tests. Sometimes blood disorders can occur if you take TAZOCIN EF.
If a doctor asks you for a urine sample, tell him/her that you are receiving TAZOCIN EF. Antibiotics in the penicillin family, including TAZOCIN EF, can cause interference in some tests for glucose in urine. Penicillins that are excreted in urine can cause a false-positive result. The doctor will request a test, which is not affected by penicillins.
