6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the label: Cardiovascular and Central Nervous System effects [see Warnings and Precautions (5.1)] Increased intraocular pressure [see Warnings and Precautions (5.2)] Urinary retention in patients with prostatic hypertrophy [see Warnings and Precautions (5.2)] Hypersensitivity reactions [see Warnings and Precautions (5.4)] Severe Skin Reactions The most common adverse reactions (reported in ≥2% of patients) were insomnia, headache, mouth dry, fatigue, somnolence, pharyngitis, dizziness, nausea, and anorexia. (6.1) To report SUSPECTED ADVERSE REACTIONS, contact Merck Sharp & Dohme Corp., a subsidiary of Merck & Co., Inc., at 1-877-888-4231 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 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. The safety data described below are from 2 clinical trials with CLARINEX-D 12 HOUR Extended Release Tablets that included 1248 patients with seasonal allergic rhinitis, of which 414 patients received CLARINEX-D 12 HOUR Extended Release Tablets twice daily for up to 2 weeks. The majority of patients were between 18 and <65 years of age with a mean age of 35.8 years and were predominantly women (64%). Patient ethnicity was 82% Caucasian, 9% Black, 6% Hispanic and 3% Asian/other ethnicity. The percentage of subjects receiving CLARINEX-D 12 HOUR Extended Release Tablets and who discontinued from the clinical trials because of an adverse event was 3.6%. Adverse reactions that were reported by ≥2% of subjects receiving CLARINEX-D 12 HOUR Extended Release Tablets are shown in Table 1. Table 1: Incidence of Adverse Reactions Reported by ≥2% of Subjects Receiving CLARINEX-D 12 HOUR Extended Release Tablets Adverse Reaction CLARINEX-D 12 HOUR BID (N=414) Desloratadine 5 mg QD (N=412) Pseudoephedrine 120 mg BID (N=422) Gastrointestinal Disorders Mouth Dry 8% 2% 8% Nausea 2% 1% 3% General Disorders and Administration Site Conditions Fatigue 4% 2% 2% Metabolism and Nutrition Disorders Anorexia 2% 0% 2% Nervous System Disorders Headache 8% 8% 9% Somnolence 3% 4% 2% Dizziness 3% 2% 2% Psychiatric Disorders Insomnia 10% 3% 13% Respiratory, Thoracic, and Mediastinal Disorders Pharyngitis 3% 3% 3% There were no relevant differences in adverse reactions for subgroups of patients as defined by gender, age, or race. 6.2 Post-Marketing Experience In addition to the adverse reactions reported during clinical trials and listed above, adverse events have been identified during post approval use of CLARINEX-D 12 HOUR Extended Release Tablets. Because these 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. Adverse events identified from post-marketing surveillance on the use of CLARINEX-D 12 HOUR Extended Release Tablets include: Cardiac disorders: tachycardia, palpitations Respiratory, thoracic and mediastinal disorders: dyspnea Skin and subcutaneous tissue disorders: rash, pruritus In addition to these events, the following spontaneous adverse events have been reported during the marketing of desloratadine as a single ingredient product: Nervous system disorders: headache, somnolence, dizziness, 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 Cases of severe skin reactions such as acute generalized exanthematous pustulosis (AGEP) have been reported with pseudoephedrine-containing products.

Usage information

Dosing and administration
2 DOSAGE AND ADMINISTRATION Administer CLARINEX-D 12 HOUR Extended Release Tablet by the oral route only. Do not break, chew, or crush the tablet. Swallow the tablet whole. For oral use only (2) Adults and adolescents 12 years of age and over: The recommended dose of CLARINEX-D 12 HOUR Extended Release Tablets is one tablet twice a day. (2.1) 2.1 Adults and Adolescents 12 years of Age and Over The recommended dose of CLARINEX-D 12 HOUR Extended Release Tablets is 1 tablet twice a day, administered approximately 12 hours apart and with or without a meal. Higher doses or increased dosing frequency of CLARINEX-D 12 HOUR Extended Release Tablets have not demonstrated increased effectiveness. Do not exceed the recommended dose as desloratadine and pseudoephedrine, the active components of CLARINEX-D 12 HOUR Extended Release Tablets have been associated with adverse effects at higher doses [see Overdosage (10.1) and (10.2)].
Use in special populations
8 USE IN SPECIFIC POPULATIONS Renal impairment: Avoid in patients with renal impairment. (8.6) Hepatic impairment: Avoid in patients with hepatic impairment. (8.7) 8.1 Pregnancy Pregnancy Category C: There are no adequate and well-controlled studies of desloratadine and pseudoephedrine in combination in pregnant women. Neither are there animal reproduction studies conducted with the combination of desloratadine and pseudoephedrine. Desloratadine was not teratogenic in rats or rabbits but affected implantation in rats. Because animal reproduction studies are not always predictive of human response, CLARINEX-D 12 HOUR Extended Release Tablets should be used during pregnancy only if clearly needed. Desloratadine was not teratogenic in rats or rabbits at approximately 210 and 230 times, respectively, the AUC in humans at the recommended daily oral dose. An increase in pre-implantation loss and a decreased number of implantations and fetuses were noted, however, in a separate study in female rats at approximately 120 times the AUC in humans at the recommended daily oral dose. Reduced body weight and slow righting reflex were reported in pups at approximately 50 times or greater than the AUC in humans at the recommended daily oral dose. Desloratadine had no effect on pup development at approximately 7 times the AUC in humans at the recommended daily oral dose. The AUCs in comparison referred to the desloratadine exposure in rabbits and the sum of desloratadine and its metabolites exposures in rats, respectively [see Nonclinical Toxicology (13.2)]. 8.3 Nursing Mothers Desloratadine and pseudoephedrine both pass into breast milk; therefore, a decision should be made whether to discontinue nursing or to discontinue CLARINEX-D 12 HOUR Extended Release Tablets, taking into account the benefit of the drug to the nursing mother and the possible risk to the child. 8.4 Pediatric Use CLARINEX-D 12 HOUR Extended Release Tablets are not indicated for use in pediatric patients under 12 years of age. 8.5 Geriatric Use The number of subjects (n=10) ≥65 years old treated with CLARINEX-D 12 HOUR Extended Release Tablets was too limited to make any formal statistical comparison regarding the efficacy or safety of this drug product in this age group, or to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences between the elderly and younger patients, although the elderly are more likely to have adverse reactions to sympathomimetic amines. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy [see Clinical Pharmacology (12.3)]. Pseudoephedrine, desloratadine, and their metabolites are known to be substantially excreted by the kidney, and the risk of adverse reactions may be greater in patients with renal impairment. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor the patient for adverse events [see Clinical Pharmacology (12.3)]. 8.6 Renal Impairment No studies with CLARINEX-D 12 HOUR Extended Release Tablets were conducted in subjects with renal impairment. CLARINEX-D 12 HOUR Extended Release Tablets should generally be avoided in patients with renal impairment [see Warnings and Precautions (5.5) and Clinical Pharmacology (12.3)]. 8.7 Hepatic Impairment No studies with CLARINEX-D 12 HOUR Extended Release Tablets or pseudoephedrine were conducted in subjects with hepatic impairment. CLARINEX-D 12 HOUR Extended Release Tablets should generally be avoided in patients with hepatic impairment [see Warnings and Precautions (5.6) and Clinical Pharmacology (12.3)]. 8.8 Gender No clinically significant gender-related differences were observed in the pharmacokinetic parameters of desloratadine, 3-hydroxydesloratadine or pseudoephedrine following administration of CLARINEX-D 12 HOUR Extended Release Tablets. 8.9 Race No studies have been conducted to evaluate the effect of race on the pharmacokinetics of CLARINEX-D 12 HOUR Extended Release Tablets.
Pregnancy and lactation
8.3 Nursing Mothers Desloratadine and pseudoephedrine both pass into breast milk; therefore, a decision should be made whether to discontinue nursing or to discontinue CLARINEX-D 12 HOUR Extended Release Tablets, taking into account the benefit of the drug to the nursing mother and the possible risk to the child.

Interactions

7 DRUG INTERACTIONS No specific interaction studies have been conducted with CLARINEX-D 12 HOUR Extended Release Tablets. Monoamine Oxidase (MAO) Inhibitors: Do not use. May potentiate the effect of pseudoephedrine on vascular system. (7.1) 7.1 Monoamine Oxidase Inhibitors CLARINEX-D 12 HOUR Extended Release Tablets should not be used in patients receiving monoamine oxidase (MAO) inhibitor therapy or within fourteen (14) days of stopping such treatment because the action of pseudoephedrine a component of CLARINEX-D 12 HOUR Extended Release tablets on the vascular system may be potentiated by these agents [see Contraindications (4) and Warnings and Precautions (5.3)]. 7.2 Beta-Adrenergic Blocking Agents The antihypertensive effects of beta-adrenergic blocking agents, methyldopa, and reserpine, may be reduced by sympathomimetics such as pseudoephedrine. Exercise caution when using CLARINEX-D 12 HOUR Extended Release Tablets with these agents. 7.3 Digitalis Increased ectopic pacemaker activity can occur when pseudoephedrine is used concomitantly with digitalis. Exercise caution when using CLARINEX-D 12 HOUR Extended Release Tablets with these agents. 7.4 Inhibitors of Cytochrome P450 3A4 In controlled clinical studies co-administration of desloratadine with ketoconazole, erythromycin, or azithromycin resulted in increased plasma concentrations of desloratadine and 3-hydroxydesloratadine but there were no clinically relevant changes in the safety profile of desloratadine [see Clinical Pharmacology (12.3)]. 7.5 Fluoxetine In controlled clinical studies co-administration of desloratadine with fluoxetine, a selective serotonin reuptake inhibitor (SSRI), resulted in increased plasma concentrations of desloratadine and 3-hydroxydesloratadine but there were no clinically relevant changes in the safety profile of desloratadine [see Clinical Pharmacology (12.3)]. 7.6 Cimetidine In controlled clinical studies co-administration of desloratadine with cimetidine a histamine H2-receptor antagonist resulted in increased plasma concentrations of desloratadine and 3-hydroxydesloratadine but there were no clinically relevant changes in the safety profile of desloratadine [see Clinical Pharmacology (12.3)].
