Side effects of Despej in details
The following adverse reactions are discussed in greater detail in other sections of the label:
- Hypersensitivity reactions.
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 Despej 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 Despej and placebo-treated patients. The percent of patients who withdrew prematurely due to adverse events was 2.4% in the Despej group and 2.6% in the placebo group. There were no serious adverse events in these trials in patients receiving Despej. All adverse events that were reported by greater than or equal to 2% of patients who received the recommended daily dose of Despej tablets (5 mg once daily), and that were more common with Despej tablets than placebo, are listed in Table 1.
The frequency and magnitude of laboratory and electrocardiographic abnormalities were similar in Despej 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 Despej tablets and 205 received placebo. Adverse events that were reported by greater than or equal to 2% of patients who received Despej tablets and that were more common with Despej than placebo were (rates for Despej 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%).

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 Despej: 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.
