Noxafil

What is Noxafil?

Noxafil (which refers to injection, delayed-release tablets, and oral suspension) and Noxafil PowderMix (for delayed-release oral suspension) are prescription medicines used in adults and children to help prevent or treat fungal infections that can spread throughout your body (invasive fungal infections).

These infections are caused by fungi called Aspergillus or Candida. Noxafil and Noxafil PowderMix are used in people who have an increased chance of getting these infections due to a weak immune system. These include people who have had a hematopoietic stem cell transplantation (bone marrow transplant) with graft versus host disease or those with a low white blood cell count due to chemotherapy for blood cancers (hematologic malignancies).

Noxafil injection is used for:

• prevention of fungal infections in adults and children 2 years of age and older.
• treatment of fungal infections in adults and children 13 years of age and older.

Noxafil delayed-release tablets are used for:

• prevention of fungal infections in adults and children 2 years of age and older who weigh greater than 88 lbs (40 kg).
• treatment of fungal infections in adults and children 13 years of age and older.

Noxafil oral suspension is used for:

• prevention of fungal infections in adults and children 13 years of age and older.

Noxafil PowderMix for delayed-release oral suspension is used for:

• prevention of fungal infections in children 2 years of age and older who weigh 88 lbs (40 kg) or less.

Noxafil oral suspension is also used to treat a fungal infection called “thrush” caused by Candida in your mouth or throat area. Noxafil oral suspension can be used as the first treatment for thrush, or as another treatment for thrush after itraconazole or fluconazole treatment has not worked.

Noxafil oral suspension is for adults and children 13 years of age and older.

Get to know the oral syringes

Before you prepare a dose, review the parts of the syringe and how to use them. If you have any questions about measuring with a syringe, call your healthcare provider. Make sure the plunger is pushed all the way into the barrel before you start to measure the dose.

• Look for the number on the measuring scale that matches the amount of mixing liquid or Noxafil PowderMix that you need.
• Be sure to follow the directions in this booklet to remove air bubbles from the syringe. Air bubbles can affect the amount of medicine that the child gets.

Step 1. Get the mixing liquid ready.

When you use the mixing liquid for the first time:

• Open the bottle and remove the safety seal.
• Place the bottle adapter on top of the bottle with the small hole facing up.
• Push the bottle adapter all the way down.
• After it is in place, the bottle adapter stays in the bottle.
• Put the cap back on the bottle.

Step 2. Gather all your supplies and put on a clean surface.

1 mixing cup (Using the tab on the mixing cup, pull open the lid.)	1 packet of Noxafil PowderMix powder	Mixing liquid	2 syringes (Have 1 of each size ready, but you may only use 1, depending on the dose.)	Scissors (not included with kit: use sharp household scissors or kitchen scissors)
		The Noxafil PowderMix box has a mixing cup holder inside to help tilt the cup when you are measuring the dose.

Step 3. Add Noxafil PowderMix to the mixing cup

Take 1 packet of Noxafil PowderMix and shake the powder to the bottom of the packet.
Cut open the packet of Noxafil PowderMix at the dotted line and add all of the Noxafil PowderMix to the mixing cup. Make sure the packet of Noxafil PowderMix is completely empty.

Step 4. Shake the mixing liquid bottle.

Shake the mixing liquid well before each time you prepare Noxafil PowderMix.

Step 5. Fill the blue syringe with 9 mL of mixing liquid.

Push the plunger of the blue syringe into the syringe barrel as far as it goes. Remove the cap from the bottle of mixing liquid. Push the notched tip of the syringe into the bottle adapter. With the syringe attached to the bottle, turn.the bottle and syringe upside down. With your other hand, pull back the plunger to draw the mixing liquid back into the syringe. Stop when you get to the 9 mL line. Turn the bottle back over and remove the syringe to check your measurement.

Step 6. Check for air bubbles.

Hold the syringe with notched tip up. Tap it with your finger to move any air bubbles up. Slowly push the plunger to make the air come out.
	Re-check the measurement of mixing liquid in the syringe. If it is less than 9 mL, put the notched tip back into the mixing liquid and pull the plunger back until you get to the 9 mL mark.

Step 7. Add the 9 mL of mixing liquid to the Noxafil PowderMix.

• Add the 9 mL of mixing liquid to the Noxafil PowderMix in the mixing cup by pushing all the way down on the plunger.

Step 8. Mix the Noxafil PowderMix.
