1. What Voriconazole is and what it is used for
This medicine 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 cell 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.
Prevention of fungal infections in high risk bone marrow transplant recipients.
This product should only be taken under the supervision of a doctor.
2. What you need to know before you take Voriconazole

- if you are allergic to voriconazole or any of the other ingredients of this medicine (listed in section 6).
The medicines in the following list must not be taken during your course of Voriconazole treatment:
- Terfenadine (used for allergy)
- Astemizole (used for allergy)
- Cisapride (used for stomach problems)
- Pimozide (used for treating mental illness)
- Quinidine (used for irregular heartbeat)
- Rifampicin (used for treating tuberculosis)
- Efavirenz (used for treating HIV) in doses of 400mg and above once daily
- Carbamazepine (used to treat seizures)
- Phenobarbital (used for severe insomnia and seizures)

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 heartbeat, slow heart rate or an abnormality of electrocardiogram (ECG) called ‘long QT 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. These precautions are also applicable to children.
While being treated with Voriconazole, tell your doctor immediately if you develop:
- 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.
Your doctor should monitor the function of your liver and kidneys by doing blood tests.
Children and adolescents
Voriconazole must not be given to children younger than 2 years of age.
Other medicines and Voriconazole
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
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 100mg twice daily.
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:

The recommended dose for children and adolescents is as follows:
Children aged 2 to less than 12 years and adolescents aged 12 to 14 years weighing less than 50kg:
- Dose for the first 24 hours (Loading Dose): Your treatment will be started as an infusion.

Tablets must only be given if the child is able to swallow tablets.
Take your tablet at least one hour before, or one hour after a meal. Swallow the tablet whole with some water.
If you or your child are taking Voriconazole for prevention of fungal infections, your doctor may stop giving Voriconazole if you or your child develop treatment-related side effects.
If you take more Voriconazole than you should
If you take more tablets than prescribed (or if someone else takes your tablets) you must seek medical advice or go to the nearest hospital casualty department immediately. Take your box of Voriconazole tablets with you. You may experience abnormal intolerance to light as a result of taking more Voriconazole than you should.
If you forget to take Voriconazole
It is important to take your Voriconazole tablets regularly at the same time each day. If you forget to take one dose, take your next dose when it is due. Do not take a double dose to make up for a forgotten dose.
If you stop taking Voriconazole
It has been shown that taking all doses at the appropriate times may greatly increase the effectiveness of your medicine. Therefore, unless your doctor instructs you to stop treatment, it is important to keep taking Voriconazole correctly, as described above.
Continue taking Voriconazole until your doctor tells you to stop. Do not stop treatment early because your infection may not be cured. Patients with a weakened immune system or those with difficult infections may require long-term treatment to prevent the infection from returning.
When Voriconazole treatment is stopped by your doctor, you should not experience any effects.
If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
