1. What Noxafil is and what it is used for

Noxafil contains a medicine called posaconazole. This belongs to a group of medicines called “antifungals”. It is used to prevent and treat many different fungal infections.

This medicine works by killing or stopping the growth of some types of fungi that can cause infections.

Noxafil can be used in adults to treat the following types of fungal infections when other antifungal medicines have not worked or you have had to stop taking them:

  • infections caused by fungi of the Aspergillus family that have not improved during treatment with the anti-fungal medicines amphotericin B or itraconazole or when these medicines have had to be stopped;
  • infections caused by fungi of the Fusarium family that have not improved during treatment with amphotericin B or when amphotericin B has had to be stopped;
  • infections caused by fungi that cause the conditions known as “chromoblastomycosis” and “mycetoma” that have not improved during treatment with itraconazole or when itraconazole has had to be stopped;
  • infections caused by a fungus called Coccidioides that have not improved during treatment with one or more of amphotericin B, itraconazole or fluconazole or when these medicines have had to be stopped.

This medicine can also be used to prevent fungal infections in adults who are at high risk of getting a fungal infection, such as:

  • patients who have a weak immune system due to having chemotherapy for “acute myelogenous leukemia” (AML) or “myelodysplastic syndromes” (MDS)
  • patients having “high-dose immunosuppressive therapy” after “hematopoietic stem cell transplant” (HSCT).

2. What you need to know before you take Noxafil

Do not take Noxafil if:

  • you are allergic to posaconazole or any of the other ingredients of this medicine (listed in section 6).
  • you are taking: terfenadine, astemizole, cisapride, pimozide, halofantrine, quinidine, any medicines that contain “ergot alkaloids” such as ergotamine or dihydroergotamine, or a “statin” such as simvastatin, atorvastatin or lovastatin.

Do not take Noxafil if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking Noxafil.

See “Other medicines and Noxafil” below for more information including information on other medicines which may interact with Noxafil.

Warnings and precautions

Talk to your doctor, pharmacist or nurse before taking Noxafil if you:

  • have had an allergic reaction to another antifungal medicine such as ketoconazole, fluconazole, itraconazole or voriconazole.
  • have or have ever had liver problems. You may need to have blood tests while you are taking this medicine.
  • develop severe diarrhoea or vomiting, as these conditions may limit the effectiveness of this medicine.
  • have an abnormal heart rhythm tracing (ECG) that shows a problem called long QTc interval
  • have a weakness of the heart muscle or heart failure
  • have a very slow heartbeat
  • have heart rhythm disturbance
  • have any problem with potassium, magnesium or calcium levels in your blood
  • are taking vincristine, vinblastine and other “vinca alkaloids” (medicines used to treat cancer).

If any of the above apply to you (or you are not sure), talk to your doctor, pharmacist or nurse before taking Noxafil.

If you develop severe diarrhoea or vomiting (being sick) while taking Noxafil, talk to your doctor, pharmacist or nurse straight away, as this may stop it from working properly. See Section 4 for more information.

Children

Noxafil should not be used in children (17 years of age and younger).

Other medicines and Noxafil

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Do not take Noxafil if you are taking any of the following:

  • terfenadine (used to treat allergies)
  • astemizole (used to treat allergies)
  • cisapride (used to treat stomach problems)
  • pimozide (used to treat symptoms of Tourette's and mental illness)
  • halofantrine (used to treat malaria)
  • quinidine (used to treat abnormal heart rhythms).

Noxafil can increase the amount of these medicines in the blood which may lead to very serious changes to your heart rhythm:

  • any medicines that contain “ergot alkaloids” such as ergotamine or dihydroergotamine used to treat migraines. Noxafil can increase the amount of these medicines in the blood which may lead to a severe decrease in blood flow to your fingers or toes and could cause damage to them.
  • a “statin” such as simvastatin, atorvastatin or lovastatin used to treat high cholesterol.

Do not take Noxafil if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking this medicine.

Other medicines

Look at the list of medicines given above that must not be taken while you are taking Noxafil. In addition to the medicines named above there are other medicines that carry a risk of rhythm problems that may be greater when they are taken with Noxafil. Please make sure you tell your doctor about all the medicines you are taking (prescribed or non-prescribed).

Certain medicines may increase the risk of side effects of Noxafil by increasing the amount of Noxafil in the blood.

The following medicines may decrease the effectiveness of Noxafil by decreasing the amount of Noxafil in the blood:

  • rifabutin and rifampicin (used to treat certain infections). If you are already taking rifabutin, you will need a blood test and you will need to look out for some possible side effects of rifabutin.
  • some medicines used to treat or prevent fits including; phenytoin, carbamazepine, phenobarbital or primidone).
  • efavirenz and fosamprenavir used to treat HIV infection.

Noxafil may possibly increase the risk of side effects of some other medicines by increasing the amount of these medicines in the blood. These medicines include:

  • vincristine, vinblastine and other “vinca alkaloids” (used to treat cancer)
  • ciclosporin (used during or after transplant surgery)
  • tacrolimus and sirolimus (used during or after transplant surgery)
  • rifabutin (used to treat certain infections)
  • medicines used to treat HIV called protease inhibitors (including lopinavir and atazanavir, which are given with ritonavir)
  • midazolam, triazolam, alprazolam or other “benzodiazepines” (used as sedatives or muscle relaxants)
  • diltiazem, verapamil, nifedipine, nisoldipine or other “calcium channel blockers” (used to treat high blood pressure)
  • digoxin (used to treat heart failure)
  • Glipizide or other “sulfonylureas” (used to treat high blood sugar).

If any of the above apply to you (or you are not sure), talk to your doctor or pharmacist before taking Noxafil.
