  • 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 with Voriconazole Sandoz. 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.

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.
