The following dosing information is available for DESLORATADINE (desloratadine):
No enhanced Dosing information available for this drug.
Desloratadine is administered orally once daily without regard to meals. Desloratadine orally disintegrating tablets are administered by placing a tablet on the tongue, allowing it to disintegrate, and then subsequently swallowing with or without water. Patients receiving desloratadine orally disintegrating tablets should be instructed not to remove a tablet from the blister until just prior to dosing.
Desloratadine oral solution should be administered using a commercially available dropper or syringe that is calibrated to deliver 2 or 2.5 mL. Extended-release tablets containing desloratadine in fixed combination with pseudoephedrine sulfate should be swallowed intact and should not be chewed, broken, or crushed.
Commercially available desloratadine conventional tablets and oral solution are bioequivalent. The currently available reformulated orally disintegrating tablets containing 5 mg of desloratadine are bioequivalent to the original orally disintegrating formulation (no longer commercially available), which previously was shown to be bioequivalent to desloratadine conventional tablets and oral solution.

The following drug interaction information is available for DESLORATADINE (desloratadine):
There are 0 contraindications.
There are 2 severe interactions.
These drug interactions can produce serious consequences in most patients. Actions required for severe interactions include, but are not limited to, discontinuing one or both agents, adjusting dosage, altering administration scheduling, and providing additional patient monitoring. Review the full interaction monograph for more information.
| Drug Interaction | Drug Names |
|---|---|
| Radioactive Iodide/Agents that Affect Iodide SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Many compounds can affect iodide protein binding and alter iodide pharmacokinetics and pharmacodynamics.(1) CLINICAL EFFECTS: Compounds that affect iodide pharmacokinetics and pharmacodynamics may impact the effectiveness of radioactive iodide.(1) PREDISPOSING FACTORS: Compounds that affect iodide pharmacokinetics and pharmacodynamics are expected to have the most impact during therapy using radioactive iodide. Diagnostic procedures would be expected to be impacted less. PATIENT MANAGEMENT: Discuss the use of agents that affect iodide pharmacokinetics and pharmacodynamics with the patient's oncologist.(1) Because indocyanine green contains sodium iodide, the iodine-binding capacity of thyroid tissue may be reduced for at least one week following administration. Do not perform radioactive iodine uptake studies for at least one week following administration of indocyanine green.(2) The manufacturer of iopamidol states administration may interfere with thyroid uptake of radioactive iodine and decrease therapeutic and diagnostic efficacy. Avoid thyroid therapy or testing for up to 6 weeks post administration of iopamidol.(3) DISCUSSION: Many agents interact with radioactive iodine. The average duration of effect is: anticoagulants - 1 week antihistamines - 1 week anti-thyroid drugs, e.g: carbimazole, methimazole, propylthiouracil - 3-5 days corticosteroids - 1 week iodide-containing medications, e.g: amiodarone - 1-6 months expectorants - 2 weeks Lugol solution - 3 weeks saturated solution of potassium iodine - 3 weeks vitamins - 10-14 days iodide-containing X-ray contrast agents - up to 1 year lithium - 4 weeks phenylbutazone - 1-2 weeks sulfonamides - 1 week thyroid hormones (natural or synthetic), e.g.: thyroxine - 4 weeks tri-iodothyronine - 2 weeks tolbutamide - 1 week topical iodide - 1-9 months (1) |

The following precautions are available for DESLORATADINE (desloratadine):
Safety and efficacy have not been established for symptomatic management of seasonal allergic rhinitis in children younger than 2 years of age. Safety and efficacy have not been established for symptomatic management of perennial allergic rhinitis or chronic idiopathic urticaria in children younger than 6 months of age. Safety and efficacy of the fixed-combination preparation containing desloratadine and pseudoephedrine sulfate for symptomatic management of seasonal allergic rhinitis have not been established in children younger than 12 years of age.
Overdosage and toxicity (including death) have been reported in children younger than 2 years of age receiving nonprescription (over-the-counter, OTC) preparations containing antihistamines, cough suppressants, expectorants, and nasal decongestants alone or in combination for relief of symptoms of upper respiratory tract infection. Clinicians should ask caregivers about use of nonprescription cough and cold preparations to avoid overdosage. For additional information on precautions associated with the use of cough and cold preparations in pediatric patients, see Cautions: Pediatric Precautions in the Antihistamines General Statement 4:00.

Desloratadine is distributed into milk. Discontinue nursing or the drug, taking into account the importance of the drug to the woman. Exercise caution if the fixed-combination preparation containing desloratadine and pseudoephedrine sulfate is used in nursing women.
Experience with desloratadine in those 65 years of age and older is insufficient to determine whether they respond differently from younger adults. In one study, peak plasma concentrations and area under the plasma concentration-time curve (AUC) of desloratadine were increased (by 20%) and plasma elimination half-life was prolonged in geriatric patients compared with younger adults; however, these age-related differences do not appear to be clinically important. Nevertheless, dosage should be selected with caution because of the greater frequency of decreased hepatic, renal, and/or cardiac function and of concomitant disease and drug therapy observed in geriatric patients.
