The most commonly reported adverse reactions in pediatric patients included somnolence, dizziness, dysgeusia, oral paresthesia, nausea, increased appetite, fatigue, and increased weight.^[Ref]

Nervous system

• Very common (10% or greater): Somnolence (up to 53%), extrapyramidal symptoms (up to 25%), sedation (up to 19.2%), akathisia (up to 15%), headache (up to 11%), dizziness (up to 10.1%)

• Frequency not reported: Bradykinesia, cerebrovascular events, hyperkinesia, hypersomnia, lethargy, motor impairment, myoclonus, resting tremor, tardive dyskinesia^[Ref]

Somnolence occurred in up to 53% of patients aged 10 to 17 years given 5 mg orally 2 times a day.

Extrapyramidal symptoms occurred in 25% of patients given 10 mg, compared to 11% of patients given 5 mg.^[Ref]

Gastrointestinal

• Very common (10% or greater): Oral hypoesthesia (up to 30%), oral paresthesia (up to 11%)
• Common (1% to 10%): Abdominal pain, constipation, dry mouth, dyspepsia, glossodynia, nausea, oropharyngeal pain, salivary hypersecretion, stomach discomfort, toothache, vomiting

Oral hypoesthesia occurred in up to 30% of pediatric patients and up to 24% of adults.

Application site reactions that include oral ulcers, blisters, peeling/sloughing, and inflammation primarily in the sublingual area have led to discontinuation of therapy in many cases. Oral hypoesthesia and/or oral paraesthesia may occur directly after administration and usually resolve in 1 hour.^[Ref]

Psychiatric

• Very common (10% or greater): Insomnia (up to 16%)
• Common (1% to 10%): Agitation, anger, anxiety, bipolar disorder, bipolar I disorder, depression, depressive symptoms, irritability, mania, schizophrenia, suicidal ideation

• Very common (10% or greater): Fatigue (up to 14%)
• Uncommon (0.1% to 1%): Fall
• Rare (less than 0.1%): Idiosyncratic drug reaction

Metabolic

• Very common (10% or greater): Weight gain of at least 7% (up to 13.1%)

• Uncommon (0.1% to 1%): Hyperglycemia, hyponatremia
• Frequency not reported: Blood insulin increased, diabetes mellitus, dyslipidemia, metabolic changes^[Ref]

While all atypical antipsychotics have been associated with metabolic changes including hyperglycemia, dyslipidemia, and weight gain, the degree of metabolic change differs for each agent.

In clinical trials with this drug, changes from baseline in fasting glucose ranged from -0.6 to 3.8 mg/dL in adults and -0.45 to 1.43 mg/dL in pediatric patients treated with this drug for 3 to 6 weeks compared with -0.2 and -2.24 mg/dL in adults and pediatric patients receiving placebo, respectively. In a 52-week double-blind, comparator-controlled trial in primarily schizophrenic patients, the mean increase in fasting glucose from baseline was 2.4 mg/dL.

An increase of 7% or more in body weight occurred in 8% to 12% of adults and 4.4% to 4.8% of pediatric patients treated with this drug for 3 weeks compared with 1.1% and 1.6%, respectively in adults and pediatric patients receiving placebo. In a 52-week double-blind, comparator-controlled trial in primarily schizophrenic patients, the mean increase in weight from baseline was 0.9 kg.^[Ref]

Musculoskeletal

• Common (1% to 10%): Arthralgia, muscle rigidity, muscle strain, myalgia
• Frequency not reported: Involuntary muscle contractions, muscle spasms, muscle twitching, musculoskeletal stiffness, neck muscle spasm^[Ref]

Very common (10% or greater: Creatine kinase elevations (up to 11.1%)

Cardiovascular

• Common (1% to 10%): Edema, hypertension, orthostatic hypotension, peripheral edema, tachycardia
• Uncommon (0.1% to 1%): Bundle branch block, hypotension, QT prolongation on ECG, sinus bradycardia, sinus tachycardia, temporary bundle branch block
• Frequency not reported: Heart rate increased^[Ref]

In a dedicated QT study in patients with schizophrenia, doses of 5, 10, 15, and 20 mg twice a day were compared with placebo. QTc interval increases ranged from 2 to 5 msec. No patients had QTc increases of 60 msec or greater, nor did any patient experience a QTc of 500 msec or greater.

Orthostatic hypotension was reported in 4.1% of elderly subjects compared with 0.3% in the combined study populations.^[Ref]

Hepatic

• Common (1% to 10%): ALT increased, AST increased, angioedema, transient asymptomatic elevations in hepatic transaminases^[Ref]

Transient elevations in serum transaminases (primarily ALT) in the short-term schizophrenia and bipolar mania trials were more common in treated patients but mean changes were not clinically relevant. In short-term, placebo-controlled schizophrenia trials, the mean increase in transaminase levels for treated patients was 1.6 units/L compared to a decrease of 0.4 units/L for placebo treated patients. The proportion of patients with transaminase elevations three or more times the ULN (at the endpoint) was 0.9% for treated patients versus 1.3% for placebo treated patients. In short-term, placebo-controlled bipolar mania trials, the mean increase in transaminase levels for treated patients was 8.9 units/L compared to a decrease of 4.9 units/L in placebo treated patients. The proportion of patients with transaminase elevations three or more times the ULN (at the endpoint) was 2.5% for treated patients versus 0.6% for placebo treated patients. No cases of more severe liver injury were seen. In a 52 week, double-blind, comparator controlled trial of patients with schizophrenia and schizoaffective disorder, the mean increase from baseline of ALT was 1.7 units/L.^[Ref]
