Unimed Levocetirizine Drug Interactions





Full Prescribing Info
Drug Interactions
No interactions studies have been performed with levocetirizine (including no studies with CYP3A3 inducer); studies with the racemate compound cetirizine demonstrated that there were no clinically relevant adverse interactions (with pseudoephedrine, cimetidine, ketoconazole, erythromycin, azithromycin, glipizide and diazepam). A small decrease in the clearance of cetirizine (16%) was observed in a multiple dose study with theophylline (400 mg once a day); while the disposition of theophylline was not altered by concomitant cetirizine administration. The extent absorption of levocetirizine is not reduced with food, although the rate of absorption is decreased. In sensitive patients the simultaneous administration of cetirizine or levocetirizine and alcohol or other CNS depressants may have effects on the central nervous system, although it has been shown that the racemate cetirizine does not potentiate the effect of alcohol.
