Clinical Question

Are second-generation H1-antihistamines effective for the suppression of chronic spontaneous urticaria?

Evidence-Based Answer

There is good evidence that second-generation H1-antihistamines are helpful in the short- and intermediate-term suppression of urticaria. Cetirizine (Zyrtec) in a dosage of 10 mg daily is effective at completely suppressing symptoms of chronic spontaneous urticaria (number needed to treat [NNT] = 4).1 (Strength of Recommendation: A, based on consistent, good-quality patient-oriented evidence.)

Practice Pointers

Chronic spontaneous urticaria affects up to 1% of the general population.2 The economic burden of chronic spontaneous urticaria in the United States is estimated to be $2.5 billion to $5 billion annually.3 Second-generation H1-antihistamines are recommended as the mainstay of treatment for chronic spontaneous urticaria.4 The authors of this study sought to determine if second-generation H1-antihistamines are effective for the relief of chronic spontaneous urticaria and whether one agent is superior to others. Further, they sought to determine optimal dosing regimens, whether duration of benefits can be predicted, and the risks associated with use of these medications.

This Cochrane review included 73 studies with 9,759 participants.1 Methodologic quality of the included
