Warnings and precautions

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

  • you have or have previously had liver disease. If you have liver disease, your doctor may prescribe a lower dose of Voriconazole Teva. The doctor must also check your liver function through blood tests while you are being treated with Voriconazole Teva.
  • you have a known disease of the heart muscle, irregular heartbeats, slow heartbeats, or an ECG change called “long QTc syndrome”.

Avoid sunlight and exposure to the sun while you are being treated. It is important to cover exposed areas of the skin and to use sunscreen with a high sun protection factor (SPF), as the skin can become more sensitive to the sun’s UV rays. These precautions also apply to children.

While you are being treated with Voriconazole Teva, tell your doctor immediately if you get:

  • sun damage
  • severe skin rash or blisters
  • bone pain.

If you develop the above skin problems, your doctor may refer you to a dermatologist who, after a consultation, may decide that it is important for you to be examined regularly. There is a small risk of developing skin cancer during long-term use of voriconazole.

Tell your doctor if you develop signs of ‘adrenal insufficiency. This means that the adrenal glands do not produce enough of certain steroid hormones such as cortisol, which can lead to symptoms such as chronic or prolonged fatigue, muscle weakness, loss of appetite, weight loss, and abdominal pain.

Talk to your doctor if you develop signs of Cushing’s syndrome. This means that the body produces too much of the hormone cortisol, which can lead to symptoms such as weight gain, lumps of fat between the shoulder blades, a round face, darker skin on the stomach, thighs, breasts, and arms, thin skin, bruising more easily, high blood sugar, excessive hair growth, excessive sweating.

Your doctor checks liver and kidney function by taking certain blood samples.
