What is Desloratadine?

Desloratadine is an antihistamine that reduces the effects of the natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.

Desloratadine is used to treat the symptoms of allergies, such as sneezing, watery eyes, and runny nose. It is also used to treat skin hives and itching in people with chronic skin reactions.

Desloratadine may also be used for purposes not listed in this medication guide.

Desloratadine indications

An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.

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%).

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.

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: 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.
