Interactions between your drugs

Major

buprenorphine grepafloxacin

Applies to: buprenorphine / naloxone and grepafloxacin

CONTRAINDICATED: Grepafloxacin can cause dose-related prolongation of the QT interval. Theoretically, coadministration with other agents that can prolong the QT interval may result in additive effects and increased risk of ventricular arrhythmias including torsade de pointes and sudden death.

MANAGEMENT: Coadministration of grepafloxacin with other drugs that can prolong the QT interval is considered contraindicated.

Drug and food interactions

Major

buprenorphine food

Applies to: buprenorphine / naloxone

GENERALLY AVOID: Alcohol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics including buprenorphine. Concomitant use may result in additive CNS depression and impairment of judgment, thinking, and psychomotor skills. In more severe cases, hypotension, respiratory depression, profound sedation, coma, or even death may occur.

MANAGEMENT: Patients taking buprenorphine should not consume alcohol or use medications that contain alcohol on days of buprenorphine dosing. In general, potent narcotics such as buprenorphine should not be combined with alcohol.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
