Propoxyphene HCl 65 Interactions
The CNS-depressant effect of propoxyphene is additive with that of other CNS depressants, including alcohol.
As is the case with many medicinal agents, propoxyphene may slow the metabolism of a concomitantly administered drug. Should this occur, the higher serum concentrations of that drug may result in increased pharmacologic or adverse effects of that drug. Such occurrences have been reported when propoxyphene was administered to patients on antidepressants, anticonvulsants, or warfarin-like drugs. Sever neurologic signs, including coma, have occurred with concurrent use of carbamazepine.
