Consumer:

Abiraterone may increase the blood levels of romiDEPsin. You may be more likely to experience side effects such as anemia, bleeding problems, infections, or an irregular heart rhythm that may be serious or life-threatening. Contact your doctor if you develop paleness, fatigue, dizziness, fainting, unusual bruising or bleeding, fever, chills, diarrhea, sore throat, muscle aches, shortness of breath, blood in phlegm, weight loss, red or inflamed skin, body sores, and pain or burning during urination. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with these medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Professional:

MONITOR: Coadministration with inhibitors of P-glycoprotein (P-gp) may increase the plasma concentrations of romidepsin, which is a substrate of the efflux transporter. Although there are no formal drug interaction studies, the interaction may increase the risk of hematologic toxicities such as anemia, leukopenia, and thrombocytopenia as well as electrocardiographic changes such as QT interval prolongation and T-wave and ST-segment changes.

MANAGEMENT: Caution is advised if romidepsin is prescribed in combination with P-gp inhibitors. Pharmacologic response to romidepsin should be monitored more closely whenever a P-gp inhibitor is added to or withdrawn from therapy, and the romidepsin dosage adjusted as necessary. Patients should have complete blood cell counts, electrocardiograms, and serum electrolyte levels performed at baseline and regular intervals as recommended in the product labeling. Patients should be advised to seek medical attention if they experience symptoms that could indicate the occurrence of torsade de pointes such as dizziness, lightheadedness, fainting, palpitation, irregular heart rhythm, shortness of breath, or syncope.
