CLARITYNE Products should be administered with caution in patients with severe liver impairment (see Dosage & Administration).
The administration of CLARITYNE Products should be discontinued at least 48 hours before skin tests since antihistamines may prevent or reduce otherwise positive reactions to dermal reactivity index.
Effects on ability to drive and use machines: In clinical trials that assessed driving ability, no impairment occurred in patients receiving loratadine. However, patients should be informed that very rarely some people experience drowsiness, which may affect their ability to drive or use machines.
