Interactions between your drugs

buprenorphine oritavancin

Applies to: buprenorphine and oritavancin

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of buprenorphine, which is primarily metabolized by the isoenzyme. Reduced efficacy or withdrawal symptoms may occur in patients maintained on buprenorphine. In addition, when two or more medications with similar adverse effect profiles are given concurrently, the likelihood of experiencing these adverse reactions may be increased. For example, coadministration with other agents that can prolong the QT interval (e.g., apalutamide, encorafenib, enzalutamide) may result in additive effects and an increased risk of ventricular arrhythmias like torsade de pointes.

MANAGEMENT: Pharmacologic response to buprenorphine should be monitored more closely whenever a CYP450 3A4 inducer is added to or withdrawn from therapy, and the buprenorphine dosage adjusted as necessary. If the CYP450 3A4 inducer also carries a risk of prolonging the QT interval, then obtaining more frequent electrocardiograms (ECGs) to monitor the QT interval may be advisable. Patients should be counseled to seek immediate medical attention if they experience symptoms that could indicate the occurrence of torsade de pointes such as dizziness, lightheadedness, syncope, palpitations, irregular heartbeat, and/or shortness of breath. The prescribing information for the concomitant CYP450 3A4 inducers should be consulted for specific recommendations.

Drug and food interactions

Major

buprenorphine food

Applies to: buprenorphine

Do not use alcohol or medications that contain alcohol while you are receiving treatment with buprenorphine. This may increase nervous system side effects such as drowsiness, dizziness, lightheadedness, difficulty concentrating, and impairment in thinking and judgment. In severe cases, low blood pressure, respiratory distress, fainting, coma, or even death may occur. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. Do not use more than the recommended dose of buprenorphine, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medication without first talking to your doctor.
