Drug Interaction Report

MONITOR: Additive central nervous system and cardiorespiratory depressant effects may occur when fospropofol or propofol is administered with other depressants such as sedative-hypnotic agents and narcotic analgesics.

MANAGEMENT: Patients should be monitored closely for excessive sedation and cardiorespiratory depression, and the medication dosage(s) adjusted accordingly. Supportive therapy should be provided if needed.

GENERALLY AVOID: Use of anticholinergic agents with alcohol may result in sufficient impairment of attention so as to render driving and operating machinery more hazardous. In addition, the potential for abuse may be increased with the combination. The mechanism of interaction is not established but may involve additive depressant effects on the central nervous system. No effect of oral propantheline or atropine on blood alcohol levels was observed in healthy volunteers when administered before ingestion of a standard ethanol load. However, one study found impairment of attention in subjects given atropine 0.5 mg or glycopyrrolate 1 mg in combination with alcohol.

MANAGEMENT: Alcohol should generally be avoided during therapy with anticholinergic agents. Patients should be counseled to avoid activities requiring mental alertness until they know how these agents affect them.
