Dosage Adjustments in Patients with Hepatic Impairment:

• Reduce dosage for adult patients with moderate hepatic impairment (35 mg once daily, with a 70 mg loading dose on Day 1 where appropriate).

Dosage Adjustments in Patients Receiving Concomitant Inducers of Hepatic CYP Enzymes.

Adult Patients:

• When Cancidas is co-administered to adult patients with other inducers of hepatic CYP enzymes such as nevirapine, efavirenz, carbamazepine, dexamethasone, or phenytoin, administration of a daily dose of 70 mg of Cancidas should be considered.
• Adult patients on rifampin should receive 70 mg of Cancidas once daily.

Pediatric Patients:

• When Cancidas is co-administered to pediatric patients with other inducers of hepatic CYP enzymes, such as efavirenz, nevirapine, phenytoin, dexamethasone, or carbamazepine, a Cancidas dose of 70 mg/m2 once daily (not to exceed 70 mg) should be considered.

Administration:

• Caspofungin injection comes as a powder to be mixed with liquid and injected intravenously (into a vein) over approximately 1 hour once a day.
• Administer by slow intravenous (IV) infusion over approximately 1 hour.

Discontinue Cancidas at the first sign or symptom of a hypersensitivity reaction and administer appropriate treatment.
• Laboratory abnormalities in liver function tests have been seen in healthy volunteers and in adult and pediatric patients treated with Cancidas. Isolated cases of hepatic dysfunction, hepatitis, or hepatic failure have been reported. Monitor patients who develop abnormal liver enzymes for evidence of worsening hepatic function, and evaluate risk/benefit of continuing Cancidas.
• Elevated liver enzymes have occurred in patients receiving Cancidas and cyclosporine concomitantly. Limit use to patients for whom potential benefit outweighs potential risk. Monitor patients who develop abnormal liver function tests (LFTs) during concomitant use with Cancidas.
• Advise female patients of the potential risks to a fetus. Instruct patients to tell their healthcare provider if they are pregnant, become pregnant, or are thinking about becoming pregnant. Instruct patients to tell their healthcare provider if they plan to breastfeed their infant.
