6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the label: Hypersensitivity reactions. [See Warnings and Precautions (5.1) .] The most common adverse reactions (reported in ≥2% of adult and adolescent patients with allergic rhinitis and greater than placebo) were pharyngitis, dry mouth, myalgia, fatigue, somnolence, dysmenorrhea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Morepen Bio Inc. 666, Plainsboro Road, Suite 215 Plainsboro, NJ 08536, USA.

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. Table 1 Incidence of Adverse Events Reported by ≥2% of Adult and Adolescent Allergic Rhinitis Patients Receiving Desloratadine Tablets Adverse Event Desloratadine Tablets 5 mg (n=1655) Placebo (n=1652) Infections and Infestations Pharyngitis 4.1% 2.0% Nervous System Disorders Somnolence 2.1% 1.8% Gastrointestinal Disorders Dry Mouth 3.0% 1.9% Musculoskeletal and Connective Tissue Disorders ​​​​​​​ Myalgia 2.1% 1.8% Reproductive System and Breast Disorders Dysmenorrhea 2.1% 1.6% General Disorders and Administration Site Conditions ​​ Fatigue 2.1% 1.2% 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 Two hundred and forty-six pediatric subjects 6 months to 11 years of age received Desloratadine Oral Solution for 15 days in three placebo-controlled clinical trials. 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%). In subjects 12 months to 23 months of age, adverse events reported for the Desloratadine product and placebo in at least 2 percent of subjects receiving Desloratadine Oral Solution and at a frequency greater than placebo were fever (16.9%, 12.9%), diarrhea (15.4%, 11.3%), upper respiratory tract infections (10.8%, 9.7%), coughing (10.8%, 6.5%), appetite increased (3.1%, 1.6%), emotional lability (3.1%, 0%), epistaxis (3.1%, 0%), parasitic infection (3.1%, 0%), pharyngitis (3.1%, 0%), rash maculopapular (3.1%, 0%). In subjects 6 months to 11 months 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 upper respiratory tract infections (21.2%, 12.9%), diarrhea (19.7%, 8.1%), fever (12.1%, 1.6%), irritability (12.1%, 11.3%), coughing (10.6%, 9.7%), somnolence (9.1%, 8.1%), bronchitis (6.1%, 0%), otitis media (6.1%, 1.6%), vomiting (6.1%, 3.2%), anorexia (4.5%, 1.6%), pharyngitis (4.5%, 1.6%), insomnia (4.5%, 0%), rhinorrhea (4.5%, 3.2%), erythema (3.0%, 1.6%), and nausea (3.0%, 0%). There were no clinically meaningful changes in any electrocardiographic parameter, including the QTc interval. Only one of the 246 pediatric subjects receiving Desloratadine Oral Solution in the clinical trials discontinued treatment because of an adverse event. 6.2 Post-Marketing Experience Because adverse events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The following spontaneous adverse events have been reported during the marketing of desloratadine: Cardiac disorders: tachycardia, palpitations Respiratory, thoracic and mediastinal disorders: dyspnea Skin and subcutaneous tissue disorders: rash, pruritus Nervous system disorders: psychomotor hyperactivity, movement disorders (including dystonia, tics, and extrapyramidal symptoms), seizures (reported in patients with and without a known seizure disorder) Immune system disorders : hypersensitivity reactions (such as urticaria, edema and anaphylaxis) Investigations: elevated liver enzymes including bilirubin Hepatobiliary disorders: hepatitis Metabolism and nutrition disorders: increased appetite
