1. What Voriconazole is and what it is used for

Voriconazole tablets contain 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.

Prevention of fungal infections in high risk bone marrow transplant recipients.

This product should only be taken under the supervision of a doctor.

If you are allergic to voriconazole or any of the other ingredients of this medicine (listed in section 6).

It is very important that you inform your doctor or pharmacist if you are taking or have taken any other medicines, even those that are obtained without a prescription, or herbal medicines.

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 heart beat)
  • rifampicin (used for treating tuberculosis)
  • efavirenz (used for treating HIV) in doses of 400 mg and above once daily

  • sirolimus (used in transplant patients)
  • ritonavir (used for treating HIV) in doses of 400 mg and more twice daily

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 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. 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.

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

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)

  • indinavir and other HIV protease inhibitors (used for treating HIV)
  • non-nucleoside reverse transcriptase inhibitors (e.g., efavirenz, delavirdine, nevirapine) (used for treating HIV) (some doses of efavirenz can NOT be taken at the same time as voriconazole)
  • methadone (used to treat heroin addiction)
  • alfentanil and fentanyl and other short-acting opiates such as sufentanil (painkillers used for surgical procedures)
  • oxycodone and other long-acting opiates such as hydrocodone (used for moderate to severe pain)

  • fluconazole (used for fungal infections)
  • everolimus (used for treating advanced kidney cancer and in transplant patients)

3. How to take Voriconazole

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

Your doctor will determine your dose depending on your weight and the type of infection you have.

The recommended dose for adults (including elderly patients) is as follows:

Patients 40 kg and above

Dose for the first 24 hours (Loading dose): 400 mg every 12 hours for the first 24 hours.

Patients less than 40 kg

Dose for the first 24 hours (Loading dose): 200 mg every 12 hours for the first 24 hours.

Depending on your response to treatment, your doctor may increase the daily dose to 300 mg twice a day.

The doctor may decide to decrease the dose if you have mild to moderate cirrhosis.

Use in children and adolescents

The recommended dose for children and teenagers is as follows:

Children aged 2 to less than 12 years and teenagers aged 12 to 14 years weighing less than 50 kg

Dose for the first 24 hours (Loading dose): Your treatment will be started as an infusion.

Depending on your response to treatment, your doctor may increase or decrease the daily dose.

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.
