1.    Tap the bottle to release the powder.

2.    Remove the cap.

3.    Measure 23 ml of water by filling the measuring cup (included in the carton) to the top of the marked line then pour the water into the bottle. Using the cup measure another 23 ml of water and add this to the bottle. You should always add a total of 46 ml (2 x 23 ml) of water irrespective of the

Page 4 of 9

dose you are taking.

4.    Replace the cap and shake the bottle vigorously for about 1 minute.

5.    Remove the cap. Press the bottle adaptor into the neck of the bottle (as shown on figure below). The adaptor is provided so that you can fill the oral syringe with medicine from the bottle. Replace the cap on the bottle.

6.    Write the date of expiry of the constituted suspension on the bottle label (the shelf-life of the constituted suspension is 14 days). Any unused suspension should be discarded after this date.

Your pharmacist should advise you how to measure the medicine using the multi-dosing oral syringe

provided in the pack. Please see instructions below before using Voriconazole Pfizer suspension.

1.    Shake the closed bottle of constituted suspension for approximately 10 seconds before use. Remove the cap.

2.    While the bottle is upright, on a flat surface, insert the tip of the oral syringe into the adaptor.

3.    Turn the bottle upside down while holding the oral syringe in place. Slowly pull back the plunger of the oral syringe to the graduation mark that marks the dose for you. To measure the dose accurately, the top edge of the black ring should be lined up with the graduated mark on the oral syringe.

4.    If large bubbles can be seen, slowly push the plunger back into the syringe. This will force the medicine back into the bottle. Repeat step 3 again.

5.    Turn the bottle back upright with the oral syringe still in place. Remove the oral syringe from the bottle.

6.    Put the tip ofthe oral syringe into the mouth. Point the tip of the oral syringe towards the inside of the cheek. SLOWLY push down the plunger of the oral syringe. Do not squirt the medicine out quickly. If the medicine is to be given to a child, make sure the child is sitting, or is held, upright before giving the medicine.

Cleaning and storing the syringe:

1.    The syringe should be washed after each dose. Pull the plunger out of the syringe and wash both parts in warm soapy water. Then rinse with water.

2.    Dry the two parts. Push the plunger back in to the syringe. Keep it in a clean safe place with the medicine.

If you take more Voriconazole Pfizer than you should:

If you take more suspension than prescribed (or if someone else takes your suspension) you must seek medical advice or go to the nearest hospital casualty department immediately. Take your bottle of Voriconazole Pfizer suspension with you. You may experience abnormal intolerance to light as a result of taking more Voriconazole Pfizer than you should.

If you forget to take Voriconazole Pfizer:

It is important to take your Voriconazole Pfizer suspension regularly at the same time each day. If you forget to take one dose, take your next dose when it is due. Do not take a double dose to make up for the forgotten dose.

If you stop taking Voriconazole Pfizer:

It has been shown that taking all doses at the appropriate times may greatly increase the effectiveness of your medicine. Therefore unless your doctor instructs you to stop treatment, it is important to keep taking Voriconazole Pfizer correctly, as described above.
