Voriconazole Pfizer 200 mg powder for solution for infusion – patient leaflet, side effects, dosage

1. What Voriconazole is and what it is used for

Voriconazole contains the active substance voriconazole. Voriconazole is an antifungal medicine. It works by killing or stopping the growth of the fungi that cause infections. It is used for the treatment of patients (adults and children over the age of 2) with:

• invasive aspergillosis (a type of fungal infection due to Aspergillus sp),
• candidaemia (another type of fungal infection due to Candida sp) in non-neutropenic patients (patients without abnormally low white blood cells count),
• serious invasive Candida sp. infections when the fungus is resistant to fluconazole (another antifungal medicine), • serious fungal infections caused by Scedosporium sp. or Fusarium sp. (two different species of fungi).

Voriconazole is intended for patients with worsening, possibly life-threatening, fungal infections.

Warnings and precautions

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

• you have had an allergic reaction to other azoles. • you are suffering from, or have ever suffered from liver disease. If you have liver disease, your doctor may prescribe a lower dose of Voriconazole. Your doctor should also monitor your liver function while you are being treated with Voriconazole by doing blood tests.

• you are known to have cardiomyopathy, irregular heart beat,

  slow heart rate or an abnormality of electrocardiogram (ECG) called ‘long QTc syndrome’.

  You should avoid any sunlight and sun exposure while being treated. It is important to cover sun exposed areas of skin and use sunscreen with high sun protection factor (SPF), as an increased sensitivity of skin to the sun’s UV rays can occur. This may be further increased by other medicines that sensitise the skin to sunlight, like methotrexate. These precautions are also applicable to children.

  While being treated with Voriconazole:

  • tell your doctor immediately if you develop

    ° sunburn

    ° severe skin rash or blisters

    ° bone pain

If you develop skin disorders as described above, your doctor may refer you to a dermatologist, who after consultation may decide that it is important for you to be seen on a regular basis. There is a small chance that skin cancer could develop with long-term use of Voriconazole.

If you develop signs of ‘adrenal insufficiency’ where the adrenal glands do not produce adequate amounts of certain steroid hormones such as cortisol which may lead to symptoms such as: chronic, or long lasting fatigue, muscle weakness, loss of appetite, weight loss, abdominal pain, please tell your doctor. If you develop signs of ‘Cushing’s syndrome’ where the body produces too much of the hormone cortisol which may lead to symptoms such as: weight gain, fatty hump between the shoulders, a rounded face, darkening of the skin on the stomach, thighs breasts, and arms, thinning skin, bruising easily, high blood sugar, excessive hair growth, excessive sweating, please tell your doctor. Your doctor should monitor the function of your liver and kidney by doing blood tests.

Children and adolescents

Voriconazole should not be given to children younger than 2 years of age.

Other medicines and Voriconazole

Please tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including those that are obtained without a prescription.

• Some medicines, when taken at the same time as Voriconazole, may affect the way Voriconazole works or Voriconazole may affect the way they work.

Tell your doctor if you are taking the following medicine, as treatment with Voriconazole at the same time should be avoided if possible:

• Ritonavir (used for treating HIV) in doses of 100 mg twice daily • Glasdegib (used for treating cancer) – if you need to use both drugs your doctor will monitor your heart rhythm frequently Tell your doctor if you are taking either of the following medicines, as treatment with Voriconazole at the same time should be avoided if possible, and a dose adjustment of voriconazole may be required:
• Rifabutin (used for treating tuberculosis). If you are already being treated with rifabutin your blood counts and side effects to rifabutin will need to be monitored.
• Phenytoin (used to treat epilepsy). If you are already being treated with phenytoin your blood concentration of phenytoin will need to be monitored during your treatment with Voriconazole and your dose may be adjusted.

Tell your doctor if you are taking any of the following medicines, as a dose adjustment or monitoring may be required to check that the medicines and/ or Voriconazole are still having the desired effect:

• Warfarin and other anticoagulants (e.g., phenprocoumon, acenocoumarol; used to slow down clotting of the blood) • Ciclosporin (used in transplant patients)
• Tacrolimus (used in transplant patients)
• Sulfonylureas (e.g., tolbutamide, glipizide, and glyburide) (used for diabetes)
• Statins (e.g., atorvastatin, simvastatin) (used for lowering cholesterol)
• Benzodiazepines (e.g., midazolam, triazolam) (used for severe insomnia and stress)
• Omeprazole (used for treating ulcers)
