- invasive aspergillosis (a type of fungal infection caused by Aspergillus sp),
- candidaemia (another type of fungal infection caused by Candida sp) in non-neutropenic patients (patients who do not have an abnormally low count of white blood cells),
- serious invasive infections caused by Candida spwhen the fungus is resistant to fluconazole (another antifungal medicine),
- serious fungal infections caused by Scedosporium spor Fusarium sp(two different species of fungi).
VFEND is used in patients with serious fungal infections that may be life-threatening.
Prevention of fungal infections in patients undergoing a bone marrow transplant who are at high risk.

Warnings and precautions
Consult your doctor, pharmacist, or nurse before starting treatment with VFEND if:

- you know that you have cardiomyopathy, irregular heartbeats, slow heart rate, or an abnormality in your electrocardiogram (ECG) called "QTc prolongation".
You should avoid any exposure to the sun and sunlight during treatment. It is important that you cover exposed areas and use a sunscreen with a high sun protection factor (SPF), as you may be more sensitive to the UV rays of the sun. This sensitivity can be increased by the use of other medicines that make your skin more sensitive to sunlight, such as methotrexate. These precautions also apply to children.
While taking VFEND:
- tell your doctor if you get
- sunburn
- severe skin rash or blisters
- bone pain
If you develop skin disorders such as those described above, your doctor may refer you to a dermatologist, who may consider it important to examine you regularly. There is a small chance that you may develop skin cancer with long-term use of VFEND.
If you develop signs of "adrenal insufficiency" where the adrenal glands do not produce enough of certain steroid hormones, such as cortisol, which can cause symptoms such as: chronic or prolonged fatigue, muscle weakness, loss of appetite, weight loss, abdominal pain, tell your doctor.
If you develop signs of "Cushing's syndrome" where the body produces too much cortisol hormone which can cause symptoms such as: weight gain, hump of fat between the shoulders, rounded face, darkening of the skin of the abdomen, thighs, breasts, and arms, thin skin, easy bruising, high blood sugar levels, excessive hair growth or excessive sweating, tell your doctor.
Your doctor should monitor your liver and kidney function with blood tests.
Children and adolescents

If you or your child are taking VFEND to prevent fungal infections, your doctor may stop the administration of VFEND if you or your child experience side effects related to treatment.
If you take more VFEND than you should
If you take more tablets than you have been told to take (or if someone else takes your tablets), you must contact a doctor or go to the nearest hospital emergency department immediately. Take the VFEND pack with you. You may notice an abnormal sensitivity to light as a result of taking more VFEND than you should.
If you forget to take VFEND
It is important that you take your VFEND tablets regularly at the same time each day. If you forget to take a dose, take the next dose when it is due. Do not take a double dose to make up for a forgotten dose.
If you stop taking VFEND
It has been shown that strictly following the prescribed dose, taking each dose at the right time, can significantly increase the effectiveness of this medicine. Therefore, unless your doctor tells you to stop treatment, it is important that you continue to take VFEND as instructed above.
Continue to take VFEND until your doctor tells you to stop. Do not stop treatment early, as the infection may not be fully treated. Patients with a weakened immune system or complicated infections may need longer treatment to prevent the infection from coming back.
