Zyrtec is 3.5 times more likely than Claritin to cause sedation, particularly when used at dosages higher than 10mg/day.
However, Zyrtec is still much less sedating than older antihistamines such as promethazine.
Cetirizine was significantly more likely than loratadine to cause drowsiness and have a negative effect on motivation in one study of 60 patients with allergic rhinitis. Trials have shown both Zyrtec and Claritin are significantly more effective than placebo (a pretend pill) for reducing symptoms associated with allergic rhinitis, hay fever, and other allergies.
Trials have not consistently shown that one antihistamine is more effective than another, although one trial did report cetirizine reducing symptoms to a greater extent.
Azelastine improves all rhinitis symptoms including nasal congestion, postnasal drip, sneezing and sleeping difficulty.
