6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

Adults and Adolescents

Allergic Rhinitis: In multiple-dose placebo-controlled trials, 2834 patients ages 12 years or older received Desloratadine Tablets at doses of 2.5 mg to 20 mg daily, of whom 1655 patients received the recommended daily dose of 5 mg. In patients receiving 5 mg daily, the rate of adverse events was similar between Desloratadine and placebo-treated patients. The percent of patients who withdrew prematurely due to adverse events was 2.4% in the Desloratadine group and 2.6% in the placebo group. There were no serious adverse events in these trials in patients receiving desloratadine. All adverse events that were reported by greater than or equal to 2% of patients who received the recommended daily dose of Desloratadine Tablets (5 mg once daily), and that were more common with Desloratadine Tablets than placebo, are listed in Table 1.

The frequency and magnitude of laboratory and electrocardiographic abnormalities were similar in Desloratadine and placebo-treated patients. There were no differences in adverse events for subgroups of patients as defined by gender, age, or race.

Chronic Idiopathic Urticaria: In multiple-dose, placebo-controlled trials of chronic idiopathic urticaria, 211 patients ages 12 years or older received Desloratadine Tablets and 205 received placebo. Adverse events that were reported by greater than or equal to 2% of patients who received Desloratadine Tablets and that were more common with Desloratadine than placebo were (rates for Desloratadine and placebo, respectively): headache (14%, 13%), nausea (5%, 2%), fatigue (5%, 1%), dizziness (4%, 3%), pharyngitis (3%, 2%), dyspepsia (3%, 1%), and myalgia (3%, 1%).

Pediatrics

Pediatric subjects aged 6 to 11 years received 2.5 mg once a day, subjects aged 1 to 5 years received 1.25 mg once a day, and subjects 6 to 11 months of age received 1.0 mg once a day.

In subjects 6 to 11 years of age, no individual adverse event was reported by 2 percent or more of the subjects.

In subjects 2 to 5 years of age, adverse events reported for Desloratadine and placebo in at least 2 percent of subjects receiving Desloratadine Oral Solution and at a frequency greater than placebo were fever (5.5%, 5.4%), urinary tract infection (3.6%, 0%) and varicella (3.6%, 0%).
