1. WHAT PROMIXIN IS AND WHAT IT IS USED FOR
Promixin contains colistimethate sodium. It is an antibiotic that is given by injection to treat some types of serious infections caused by certain bacteria.
Promixin is used when other antibiotics are not suitable.
2. BEFORE YOU ARE GIVEN PROMIXIN
In certain circumstances your doctor may decide not to prescribe Promixin.
Do not have Promixin and tell your doctor if:
If this applies to you, tell your doctor before you are given Promixin.
Take special care with Promixin and tell your doctor, pharmacist or nurse if:
In premature and new-born babies, special care should be taken when using Promixin as the kidneys are not yet fully developed.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including non-prescription medicines. These medicines may interfere with the effects of Promixin.
If you suffer from myasthenia gravis and are also taking other antibiotics called macrolides (such as azithromycin, clarithromycin or erythromycin) or antibiotics called fluoroquinolones (such as ofloxacin, norfloxacin and ciprofloxacin), taking Promixin further increases the risk of muscle weakness and breathing difficulties.
Having Promixin as an infusion at the same time as receiving colistimethate sodium as an inhalation can increase your risk of side effects.
Pregnancy and breast-feeding
You may be given Promixin if you are pregnant or trying to get pregnant if your doctor considers the benefits are greater than the possible risks. It is unknown if having Promixin may harm your unborn baby.
It is not recommended that you breast-feed while you are taking this medicine as Promixin can pass into breast milk.
Driving and using machines
Promixin may make you feel dizzy, confused or have problems with your sight, such as blurred vision. If this happens to you, do not drive or use any tools or machines.
3. HOW YOU WILL BE GIVEN PROMIXIN
Your treatment with Promixin will be given to you by your doctor as an infusion into a vein over 30 – 60 minutes.
The usual daily dose in adults is 9 million international units, divided into two or three doses. If you are quite unwell, you will be given a higher dose of 9 million international units once at the start of treatment.
In some cases, your doctor may decide to give a higher daily dose of up to 12 million international units.
The usual daily dose in children weighing up to 40 Kg is 75,000 to 150,000 international units per kilogram body weight, divided into three doses. Higher doses have occasionally been given in cystic fibrosis.
Children and adults with kidney problems, including those on dialysis, are usually given lower doses. Your doctor will monitor your kidney function regularly while you receive Promixin.
If you are given too much Promixin
As a doctor or nurse will be giving you Promixin, it is unlikely that you will receive an incorrect dose. Tell your doctor or nurse if you have any concerns about the amount of medicine that you are given.
The symptoms of having too much Promixin can include:
If you were not given Promixin when expected
If you think that you have missed a dose of Promixin and it is less than 3 hours since you should have been given the dose, tell your doctor or nurse.
If it is more than 3 hours after the missed dose the doctor or nurse will wait for your next dose.
Your doctor will decide how long you should be given Promixin. It is important that your treatment is completed as advised by your doctor or your symptoms may get worse.
If you have any further questions on the use of this product, ask your doctor.
