Side effects of Desloratadine in details
A side effect of any drug can be defined as the unwanted or undesired effect produced by the drug. The side effect can be major or in few medications minor that can be ignored. Side effects not only vary from drug to drug, but it also depends on the dose of the drug, the individual sensitivity of the person, brand or company which manufactures it. If side effects overweigh the actual effect of the medicine, it may be difficult to convince the patient to take the drug. Few patients get specific side effects to specific drugs; in that case, a doctor replaces the drug with another. If you feel any side effect and it troubles you, do not forget to share with your healthcare practitioner.
The following adverse reactions are discussed in greater detail in other sections of the label:
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.

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.

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.
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: tachycardia, palpitations, rare cases of hypersensitivity reactions (such as rash, pruritus, urticaria, edema, dyspnea, and anaphylaxis), psychomotor hyperactivity, movement disorders (including dystonia, tics, and extrapyramidal symptoms), seizures, and elevated liver enzymes including bilirubin, and very rarely, hepatitis.
