Uses

What is anidulafungin used for?

Anidulafungin is an antifungal medication that fights infections caused by fungus.

Anidulafungin treats candida (yeast) infections in the blood, or in the stomach or esophagus.

Anidulafungin may also be used for purposes not listed in this medication guide.

How should I take anidulafungin?

Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Anidulafungin is injected into a vein through an IV. You may be shown how to use an IV at home. Do not self-inject this medicine if you do not understand how to give the injection and properly dispose of used needles, IV tubing, and other items used to inject the medicine.

Anidulafungin is a powder medicine that must be mixed with a liquid (diluent) before using it. You will then need to dilute this mixture into a solution with another liquid in an IV bag. If you are using the injections at home, be sure you understand how to properly mix and store the medicine.

Anidulafungin is sometimes given for up to 14 days after lab tests show that the infection has cleared. Use this medicine for the full prescribed length of time. Anidulafungin will not treat a viral infection such as the flu or a common cold.

Use a disposable needle and syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof “sharps” disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.

Do not use anidulafungin diluted solution if it has changed colors or has particles in it. Call your pharmacist for new medication.

How do I store anidulafungin?

Store the dry powder medicine in a refrigerator. Do not freeze.

After you mix the powder and diluent, you may store this mixture at room temperature for up to 24 hours before further diluting it. The final diluted solution may be stored at room temperature for up to 48 hours.

You may also store the diluted solution in a freezer for at least 72 hours before using it.
