6.1 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.
The most common adverse reactions in adult patients in clinical trials (≥5%) were weight increased, akathisia, headache, somnolence, and insomnia.
The most common adverse reactions in pediatric patients in clinical trials (≥5%) were weight increased, somnolence, headache, akathisia, and nasopharyngitis.

Dystonia Symptoms of dystonia may occur in susceptible individuals during the first few days of treatment.
Dystonic symptoms include spasm of the neck muscles, sometimes progressing to tightness of the throat, swallowing difficulty, difficulty breathing, and/or protrusion of the tongue.
While these symptoms can occur at low doses, they occur more frequently and with greater severity with high potency and at higher doses of first-generation antipsychotic drugs.
An elevated risk of acute dystonia is observed in males and younger age groups.
Other Adverse Reactions Observed during Clinical Trial Evaluation of REXULTI Other adverse reactions (≥1% frequency and greater than placebo) within the short-term, placebo-controlled trials in adult patients with MDD and schizophrenia are shown below.
The following listing does not include adverse reactions: 1) already listed in previous tables or elsewhere in the labeling, 2) for which a drug cause was remote, 3) which were so general as to be uninformative, 4) which were not considered to have clinically significant implications, or 5) which occurred at a rate equal to or less than placebo.
Eye Disorders: Vision Blurred Gastrointestinal Disorders: Nausea, Dry Mouth, Salivary Hypersecretion, Abdominal Pain, Flatulence Investigations: Blood Prolactin Increased Musculoskeletal and Connective Tissue Disorders: Myalgia Psychiatric Disorders: Abnormal Dreams Skin and Subcutaneous Tissue Disorders: Hyperhidrosis Pediatric Patients (13 to 17 years of age) In a short-term, randomized, double-blind, placebo- controlled study in pediatric patients 13 to 17 years of age with schizophrenia, safety was assessed in 110 patients in which 100 received REXULTI for at least 6 weeks.
In an on-going, 2 year, open-label study in pediatric patients 13 to 17 years of age with schizophrenia, in which safety was assessed in 194 patients of which 140 received REXULTI for at least 6 months.
Adverse reactions reported in clinical studies for this age group were generally similar to those observed in adult patients.
Hyperprolactinemia In a 6-week, placebo-controlled study in pediatric patients with schizophrenia, a 3.3 ng/mL mean increase (from baseline to last visit) was observed in the REXULTI group (versus a 2.8 ng/mL mean decrease in the placebo group) in females.
Additionally, more female subjects in the REXULTI group (28.9%, n=13) compared to the placebo group (4.7%, n=2) had shifts from normal (≤30 ng/mL) prolactin levels at baseline to abnormal (>30 ng/mL) during the course of treatment.
In males, overall mean shifts in the REXULTI group were not consistent with an increase in prolactin however, more male subjects in the REXULTI group (21.4%, n=9) compared to the placebo group (7.0%, n=3) had shifts from normal (≤20 ng/mL) prolactin levels at baseline to abnormal (>20 ng/mL) during the course of treatment.
One subject in the study experienced TEAE of galactorrhea without elevated prolactin.
6.2 Postmarketing Experience The following adverse reaction has been identified during post-approval use of REXULTI.

Other Adverse Reactions Observed during Clinical Trial Evaluation of REXULTI Other adverse reactions (≥1% frequency and greater than placebo) within the short-term, placebo-controlled trials in adult patients with MDD and schizophrenia are shown below.
The following listing does not include adverse reactions: 1) already listed in previous tables or elsewhere in the labeling, 2) for which a drug cause was remote, 3) which were so general as to be uninformative, 4) which were not considered to have clinically significant implications, or 5) which occurred at a rate equal to or less than placebo.
Eye Disorders: Vision Blurred Gastrointestinal Disorders: Nausea, Dry Mouth, Salivary Hypersecretion, Abdominal Pain, Flatulence Investigations: Blood Prolactin Increased Musculoskeletal and Connective Tissue Disorders: Myalgia Psychiatric Disorders: Abnormal Dreams Skin and Subcutaneous Tissue Disorders: Hyperhidrosis Pediatric Patients (13 to 17 years of age) In a short-term, randomized, double-blind, placebo- controlled study in pediatric patients 13 to 17 years of age with schizophrenia, safety was assessed in 110 patients in which 100 received REXULTI for at least 6 weeks.
In an on-going, 2 year, open-label study in pediatric patients 13 to 17 years of age with schizophrenia, in which safety was assessed in 194 patients of which 140 received REXULTI for at least 6 months.
Adverse reactions reported in clinical studies for this age group were generally similar to those observed in adult patients.
Hyperprolactinemia In a 6-week, placebo-controlled study in pediatric patients with schizophrenia, a 3.3 ng/mL mean increase (from baseline to last visit) was observed in the REXULTI group (versus a 2.8 ng/mL mean decrease in the placebo group) in females.
Additionally, more female subjects in the REXULTI group (28.9%, n=13) compared to the placebo group (4.7%, n=2) had shifts from normal (≤30 ng/mL) prolactin levels at baseline to abnormal (>30 ng/mL) during the course of treatment.
In males, overall mean shifts in the REXULTI group were not consistent with an increase in prolactin however, more male subjects in the REXULTI group (21.4%, n=9) compared to the placebo group (7.0%, n=3) had shifts from normal (≤20 ng/mL) prolactin levels at baseline to abnormal (>20 ng/mL) during the course of treatment.
One subject in the study experienced TEAE of galactorrhea without elevated prolactin.
6.2 Postmarketing Experience The following adverse reaction has been identified during post-approval use of REXULTI.
Because these reactions 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.
