Sleepiness: The major side-effect of zyrtec (cetirizine) is sedation - sleepiness, fatigue, and slowed reaction time. This occurs in 1 out of 10 or 1 out of 12 users. Compare to Benadryl (diphenhydramine) 1 of 3 users or clariting 1 in 50 users. Also occasionally reported are stomachache, headache, diarrhea, constipation & dry mouth & throat. In older men zyrtec can sometimes cause difficulty with urination.
