Side Effects

Like all medicines, VFEND can have side effects. If any side effects occur, most are likely to be minor and temporary. However, some may be serious and need medical attention.

The most commonly reported side effects are visual disturbances (blurring of vision, reduced vision, colour vision change and increased sensitivity to light), fever, rash, nausea, vomiting, diarrhea, headache, swelling of the extremities and stomach pains.

Other reported side effects include: changes in heart rate or rhythm, changes in blood pressure, blood cell changes, blood chemistry changes, dizziness, itchiness, weakness, back pain, chest pain, flu like symptoms, facial swelling, hallucinations and other nervous symptoms, tingling, cough, breathing difficulty, hair loss, pain and irritation of the eyes, joint pain.

The following side effects have also been reported with the use of VFEND: peripheral neuropathy (nerve damage) with symptoms such as a burning pain, tingling, numbness, sensitivity to touch and weakness, and hyponatremia (low levels of sodium in the blood) with symptoms such as nausea, vomiting, confusion, weakness, fatigue, cramps, decreased consciousness and seizures.

Check with your doctor immediately if chills, fever, flushing, sweating, muscle aches or pains, or other fIu-like symptoms occur, especially if they occur shortly before, or together with a skin rash. Also, contact your doctor in case of a fast heartbeat, chest tightness or faintness. Very rarely, these effects may be the first signs of a serious reaction to this medication.

Contact your doctor if you suffer persistent abdominal pain and tenderness or vomiting as this may be a sign of a serious condition (pancreatitis).

If you develop bone pain during treatment, contact your doctor.

You should not drive at night while taking VFEND.

Proper Use of this medication

Usual adult dose:

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

Always take VFEND exactly as directed by your doctor. You should check with your doctor or pharmacist if you are unsure. Never change the dose yourself.

Your doctor will prescribe a higher dose of VFEND on your first day of treatment to more quickly obtain an effective blood level of the antibiotic in your body.

VFEND Injection:

During the first 24 hours, you will be administered 2 doses of 6 mg/kg (12 hours apart).

After the first 24 hours:

  • If you have an Aspergillus infection, you will be administered 4 mg/kg, twice a day.
  • If you have a Candida infection, you will be administered 3 mg/kg or 4 mg/kg, twice a day.

It has been shown that taking all doses at the appropriate times may greatly increase the effectiveness of your medicine.

VFEND tablets must be taken at least one hour before or two hours after a meal. Swallow the tablet whole with some water.

VFEND oral suspension must be taken one hour before or following a meal. Shake the closed bottle for approximately 10 seconds before each use. The suspension should only be administered using the oral dispenser supplied with each pack.

VFEND oral suspension should not be mixed with any other medication or flavoring agent, and should not be further diluted with water or any other drinks.

If you have liver disease, your doctor may prescribe a lower dose of VFEND.

Your doctor may order periodic blood tests to monitor your liver function during VFEND treatment.

Continue taking VFEND 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.

Overdose:

In case of drug overdose, contact a health care practitioner, hospital emergency department or regional Poison Control Centre immediately, even if there are no symptoms.

Take your box of VFEND tablets or bottle of VFEND oral suspension with you.

Missed dose:

If you miss taking a dose of VFEND, just take the next dose when it is due. Do not take a double dose to make up for the forgotten dose.
