VFEND contains the active ingredient voriconazole. VFEND is an antifungal medication. It acts by eliminating or preventing the growth of fungi that cause infections.

It is used to treat patients (adults and children 2 years of age or older) with:

• invasive aspergillosis (a type of fungal infection produced by Aspergillus sp),
• candidemia (another type of fungal infection produced by Candida sp) in non-neutropenic patients (patients who do not have an abnormally low white blood cell count),
• serious invasive infections produced by Candida sp, when the fungus is resistant to fluconazole (another antifungal medication),
• serious fungal infections produced by Scedosporium sp or by Fusarium sp (two different species of fungi).

VFEND is used in patients with serious fungal infections that can put their lives at risk.

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

This medication must be used only under medical supervision.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting VFEND if:

• You have or have had liver disease. If you have liver disease, your doctor may prescribe a lower dose of VFEND. Your doctor should also monitor your liver function while you are taking VFEND by performing blood tests.
• You know you have heart disease, irregular heartbeats, slow heart rate, or an electrocardiogram (ECG) anomaly called "prolonged QTc syndrome."

Avoid any exposure to the sun and sunlight during treatment. It is essential to cover exposed areas and use a high-factor sunscreen, as you may experience increased skin sensitivity to UV rays from the sun. This may be exacerbated by the use of other medications that sensitize the skin to sunlight, such as methotrexate. These precautions also apply to children.

While taking VFEND:

• Inform your doctor if you experience:

• 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 may consider regular examinations. There is a small risk of developing skin cancer with long-term use of VFEND.

If you develop signs of "adrenal insufficiency" where the adrenal glands do not produce sufficient amounts of certain steroid hormones, such as cortisol, which may cause symptoms like:

• chronic or prolonged fatigue
• muscle weakness
• loss of appetite
• weight loss
• abdominal pain

Inform your doctor.

If you experience signs of "Cushing's syndrome" where the body produces too much cortisol hormone, which may cause symptoms like:

• weight gain
• hump of fat between the shoulders
• rounded face
• darkening of skin on the abdomen, thighs, breasts, and arms
• thin skin
• easily bruising
• high blood sugar levels
• excessive hair growth
• excessive sweating

Inform your doctor.

Your doctor should monitor your liver and kidney function by performing blood tests.

Children and adolescents

VFEND should not be administered to children under 2 years old.

Inform your doctor if you are using any of the following medications, as simultaneous treatment with VFEND should be avoided as much as possible, and you may need to adjust the dose of voriconazole:

If you take more VFEND than you should

If you take more tablets than prescribed (or if someone else takes your tablets), seek immediate medical assistance or go to the nearest emergency hospital. Bring the box of VFEND tablets 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 essential to take VFEND tablets regularly at the same time of day. If you forget to take a dose, take the next one when it is due. Do not take a double dose to make up for the missed dose.

If you have any other questions about the use of this medication, ask your doctor, pharmacist, or nurse.
