Known Drug Interactions

7 DRUG INTERACTIONS Cyclosporine : In two adult clinical studies, cyclosporine (one 4 mg/kg dose or two 3 mg/kg doses) increased the AUC of caspofungin. Caspofungin did not increase the plasma levels of cyclosporine. There were transient increases in liver ALT and AST when caspofungin and cyclosporine were co-administered.

Mechanism: Cyclosporine increases the levels of caspofungin in your blood and may cause temporary stress or irritation to your liver.

What to do: Your doctor should monitor your liver function tests closely if you are taking both of these medications.

Other Inducers of Hepatic CYP Enzymes Adults : When caspofungin is co-administered to adult patients with other inducers of hepatic CYP enzymes, such as efavirenz, nevirapine, phenytoin, dexamethasone, or carbamazepine, administration of a daily dose of 70 mg of caspofungin should be considered [see Dosage and Administration ( 2.5 ) and Clinical Pharmacology ( 12.3 )] . Pediatric Patients : When caspofungin is co-administered to pediatric patients with other inducers of hepatic CYP enzymes, such as efavirenz, nevirapine, phenytoin, dexamethasone, or carbamazepine, administration of a daily ...

Mechanism: Carbamazepine causes your liver to break down caspofungin faster than usual, which can lower the amount of medicine in your body.

What to do: Your doctor may need to increase your daily dose of caspofungin to 70 mg to ensure the treatment remains effective.

Other Inducers of Hepatic CYP Enzymes Adults : When caspofungin is co-administered to adult patients with other inducers of hepatic CYP enzymes, such as efavirenz, nevirapine, phenytoin, dexamethasone, or carbamazepine, administration of a daily dose of 70 mg of caspofungin should be considered [see Dosage and Administration ( 2.5 ) and Clinical Pharmacology ( 12.3 )] . Pediatric Patients : When caspofungin is co-administered to pediatric patients with other inducers of hepatic CYP enzymes, such as efavirenz, nevirapine, phenytoin, dexamethasone, or carbamazepine, administration of a daily ...

Mechanism: Phenytoin speeds up the way your liver processes caspofungin, which may reduce the medicine's ability to fight infection.

What to do: Your healthcare provider might increase your caspofungin dose to 70 mg per day when these drugs are used together.

Other Inducers of Hepatic CYP Enzymes Adults : When caspofungin is co-administered to adult patients with other inducers of hepatic CYP enzymes, such as efavirenz, nevirapine, phenytoin, dexamethasone, or carbamazepine, administration of a daily dose of 70 mg of caspofungin should be considered [see Dosage and Administration ( 2.5 ) and Clinical Pharmacology ( 12.3 )] . Pediatric Patients : When caspofungin is co-administered to pediatric patients with other inducers of hepatic CYP enzymes, such as efavirenz, nevirapine, phenytoin, dexamethasone, or carbamazepine, administration of a daily ...

Mechanism: Dexamethasone triggers your liver to clear caspofungin from your system more quickly than it normally would.

What to do: Your doctor should consider increasing your daily caspofungin dose to 70 mg to maintain the correct level of medicine in your blood.

Telaprevir Decrease AUC by 92% Systemic Hormonal Contraceptives Prevention or Management: Advise patients to change to non-hormonal methods of birth control during rifampin therapy Estrogens Decrease exposure Progestins Anticonvulsants Phenytoin Administered with rifampin 450 mg daily Decrease exposure Antiarrhythmics Disopyramide Decrease exposure Mexiletine Decrease exposure Quinidine Decrease exposure Propafenone Decrease AUC by 50%–67% Tocainide Decrease exposure Antiestrogens Tamoxifen Decrease AUC by 86% Toremifene Decrease steady state concentrations of toremifene in serum Antithromb...

Mechanism: Rifampin increases the activity of enzymes that break down other drugs, which reduces the amount of caspofungin available to fight infection.

What to do: Your doctor may need to adjust your dose of caspofungin while you are taking rifampin to ensure it stays at a helpful level.

What the FDA Data Shows for caspofungin

The FDA label for caspofungin (sold under brand names such as Cancidas) classifies it as a prescription-only medication in the Echinocandin Antifungal class. Caspofungin treats several types of fungal infections. Official labeling lists 7 commonly reported side effects, including Diarrhea, Fever, Increased liver enzyme levels.

Post-market surveillance from the FDA Adverse Event Reporting System (FAERS) captures real-world experience. For this drug, FAERS contains 2,366 voluntary reports. The database also lists 6 documented drug interactions derived from FDA labeling, with the top-flagged interaction rated minor severity. Acquisition-cost data is surveyed weekly by CMS and updated as manufacturers report changes.

Report counts do not establish causation — a FAERS entry documents a temporal association, not proof that the drug produced the outcome. Widely prescribed medications naturally accumulate more reports than niche therapies, so raw totals must be interpreted alongside total exposure. Shortage status, recall history, and patent information further shape supply and switching decisions.
