Randomized Controlled Trial Comparative Study
Double dose of cetirizine hydrochloride is effective for patients with urticaria resistant: a prospective, randomized, non-blinded, comparative clinical study and assessment of quality of life.
An increased dose of the prescribed drug or a change of the drug is recommended in the treatment for the patients with urticaria refractory to the standard dose of antihistamines. Efficacy and safety of doubling the dose of cetirizine were compared with olopatadine in the patients with symptoms like wheal or itching, despite the treatment with the standard dose of cetirizine. ⋯ Doubling the dose of cetirizine may be efficacious to the patients with urticaria refractory to the regular dose of cetirizine.
