About colistimethate sodium

Colistimethate sodium is an antibiotico which is used to treat infections caused by certain types of germs (bacteria). It works by killing the bacteria causing the infection. It is not absorbed by the body if it is taken by mouth, so instead it is given by injection or breathed into the lungs (inhaled). It is inhaled when it is for an infection which affects the lungs only (such as in people with fibrosi cistica). It is given by injection for infections which affect the body generally.

The rest of this leaflet deals with colistimethate sodium when it is inhaled for chest infections in people with conditions such as cystic fibrosis.

In people with cystic fibrosis, the cells that line the airways make phlegm (mucus) that is thicker than normal. This is not cleared from the lungs easily, and can trap bacteria and lead to infection. A germ (bacterium) called Pseudomonas aeruginosa commonly lives in the thick mucus in the airways. To keep it from flaring up into repeated infections, colistimethate sodium is inhaled into the lungs by nebuliser or inhaler device.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start using colistimethate sodium it is important that your doctor knows:

• Use colistimethate sodium exactly as your doctor tells you to. Your doctor or nurse will give you/your child the first few doses and show you what to do. Ask for further information if there is anything you are not sure about.

• If you are using a nebuliser, you will be shown how to make up the solution and how to nebulise it. As a guide only, the usual dose nebulised by adults and children over 2 years of age is 1 to 2 million units (1-2 vials) two or three times daily. This dose may be increased from time to time when needed.

  • Insert the capsule widest end first into the inhaler chamber.

  • Pierce the capsule gradually using a two-step process (your nurse/doctor will demonstrate this for you) and remember only to pierce each capsule once.

  • Place the mouthpiece between your lips and form a seal around it.

• Try not to miss any doses. If you do forget a dose, have it as soon as you remember unless it is nearly time for your next dose, in which case leave out the missed dose. Do not have two doses together to make up for a forgotten dose.

• Your doctor may recommend another type of inhaler (a bronchodilator) to widen your airways as much as possible so that colistimethate can get deeper into your lungs. If this is the case, always use the inhaler before having a dose of colistimethate sodium.

• All people with cystic fibrosis should be up to date with routine immunisations and have an annual flu jab to prevent influenza. It is also important to be immunised with pneumococcal vaccine to help prevent pneumonia caused by this bacterium.

• It is important for people with cystic fibrosis to exercise and to be as active and fit as possible. So, sports and games such as running, swimming, football and tennis are encouraged.

• If you are having an operation or dental treatment, tell the person carrying out the treatment that you are having this medicine. This is because colistimethate sodium can interfere with some anaesthetics and they may not be suitable for you.

• Se acquisti dei medicinali, verifica con un farmacista che siano adatti da assumere insieme agli altri tuoi medicinali.
