Posaconazole for fungal infections

About posaconazole

Fungal infections within the body sometimes occur. You are more at risk of developing an internal fungal infection if your immune system does not work properly. For example, if you are taking chemioterapia, or if your immune system is being suppressed following an organ or cell transplant. Internal fungal infections can be serious and, sometimes, life-threatening.

Posaconazole is used to treat (or prevent) serious fungal infections, particularly when other antifungal medicines have not been effective or are not suitable. It works by stopping the growth of the fungi causing the infection.

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 taking posaconazole it is important that your doctor knows:

• Se sei incinta o stai allattando.

• If you have liver problems.

• If you have any heart or heart rhythm problems.

• If you have porphyria, a rare inherited blood disorder.

• Se hai mai avuto una reazione allergica a un medicinale.

• If you are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines. This is because a number of medicines can interfere with the way posaconazole works.

• Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. It will give you more information about posaconazole and will provide you with a full list of side-effects which you may experience from taking it.

• Take posaconazole exactly as your doctor tells you to. How frequently you will need to take it will depend upon why you are taking it, but as a guide, it will range from once a day to four times daily if you are taking liquid medicine. If you are taking tablets, it is likely you will be prescribed 300 mg (three tablets) to take twice daily on the first day, and then 300 mg (three tablets) to take once a day on the following days.

• The tablets can be taken either before or after meals. Swallow the tablets with a drink of water. Do not crush or break the tablets - they should be swallowed whole.

• The liquid medicine should be taken during, or straight after, a meal or snack where possible as this will help your body to absorb the medicine. If you are unable to eat much, make sure your doctor knows this, as you may be better taking smaller doses more frequently. Use the spoon included in your pack to measure out your doses. It is marked for doses of 2.5 ml and 5 ml.

• Space your doses evenly throughout the day, and keep taking this medicine until your course is finished unless you are told otherwise. This is to make sure there is no chance of further infection.

• If you forget to take a dose, take it as soon as you remember. However, if when you remember, it is nearly time for your next dose, leave out the forgotten dose. Do not take two doses together to make up for a missed dose.

• Remember to keep your regular appointments with your doctor. This is so your doctor can check on your progress. Your doctor will want to do some blood tests during this treatment, to check that your liver is working properly.

• If you buy any medicines, check with a pharmacist that they are suitable to take with posaconazole. This is because several medicines interfere with it and may either decrease how well it works or increase the risk you may experience side-effects.

• You must not get pregnant while you are taking posaconazole. Make sure you have discussed with your doctor which types of contraception are suitable for you and your partner if this is relevant for you.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with posaconazole. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

If you experience any other symptoms which you think may be due to the medicine, speak with your doctor or pharmacist.

• Tenere tutti i medicinali fuori dalla portata e dalla vista dei bambini.

• Conservare in un luogo fresco e asciutto, lontano da fonti di calore e luce diretta.

• The liquid medicine keeps for four weeks once the bottle has been opened. Do not use it after this time.
