• Hypersensitivity to drug, its components, or other echinocandins


Use cautiously in:

• renal or hepatic disease

• pregnant or breastfeeding patients

• children (safety and efficacy not established).


• Administer by I.V. infusion only.

• Reconstitute with 5 ml normal saline solution injection (without bacteriostatic agent) or dextrose 5% injection added to 50-mg or 100-mg vial to yield approximately 10 mg/ml or 20 mg/ml, respectively.

• To minimize excessive foaming, gently dissolve powder by swirling vial. Don't shake vigorously.

• Protect diluted solution from light.

• Add reconstituted solution to 100 ml normal saline solution or 100 ml dextrose 5% before infusing.

• Flush existing I.V. line with normal saline solution before infusing drug.

• Infuse over 1 hour. Be aware that more rapid infusion increases risk of histamine-mediated reactions (rash, pruritus, facial swelling, vasodilation).

If serious hypersensitivity (anaphylaxis or anaphylactoid) reaction occurs, immediately discontinue infusion and provide appropriate interventions.

Calcium, glucose, magnesium, potassium: decreased levels

Liver function tests: abnormal

Patient monitoring

• If patient develops clinical or laboratory evidence of hematologic abnormalities, abnormal liver function tests, or electrolyte disorders, monitor closely for signs or symptoms that these conditions are getting worse. Risks against benefits of continuing therapy should be considered.

Patient teaching

• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs and tests mentioned above.
