Zyrtec Side Effects
Controlled and uncontrolled clinical trials aimed at Zyrtec side effects, conducted in the United States and Canada included more than 6000 patients aged 12 years and older, with more than 3900 receiving cetirizine at doses of 5 to 20 mg per day. The duration of treatment ranged from 1 week to 6 months, with a mean exposure of 30 days.
Most side effects reported during therapy with Zyrtec (cetirizine) were mild or moderate. In placebo-controlled trials, the incidence of discontinuations due to adverse reactions in patients receiving cetirizine 5 or 10 mg was not significantly different from placebo (2.9% vs. 2.4%, respectively).
The most common side effect in patients aged 12 years and older that occurred more frequently on cetirizine than placebo was somnolence. The incidence of somnolence associated with Zyrtec (cetirizine) was dose related, 6% in placebo, 11% at 5 mg and 14% at 10 mg. Discontinuations due to somnolence for cetirizine were uncommon (1.0% on cetirizine vs. 0.6% on placebo). Fatigue and dry mouth also appeared to be Zyrtec side effects. There were no differences by age, race, gender or by body weight with regard to the incidence of adverse reactions.
Zyrtec side effects are as follows:
- somnolence
- fatigue
- dry mouth
- pharyingits
