Sources: ;Very Common (>10% incidence) * Headache * Tachycardia * Somnolence (causes less sedation than most atypical antipsychotics) * Insomnia * Hyperprolactinaemia (seems to cause comparable prolactin elevation to its parent drug, risperidone) * Sexual Dysfunction ;Common (1–10% incidence) * Cough * Extrapyramidal side effects (EPSE; e.g. dystonia, akathisia, muscle rigidity, parkinsonism. It appears to produce similar EPSE to risperidone, asenapine and ziprasidone and more EPSE than olanzapine, clozapine, aripiprazole, quetiapine, amisulpride and sertindole) * Orthostatic hypotension * Weight gain (tends to produce a moderate degree of weight gain, possibly related to its potent blockade of the 5-HT2C receptor) * QT interval prolongation (tends to produce less QT interval prolongation than most other atypical antipsychotics and approximately as much QT interval prolongation as aripiprazole and lurasidone) * Nasopharyngitis * Anxiety * Indigestion * Constipation Discontinuation The British National Formulary recommends a gradual withdrawal when discontinuing antipsychotics to avoid acute withdrawal syndrome or rapid relapse. Symptoms of withdrawal commonly include nausea, vomiting, and loss of appetite. Other symptoms may include restlessness, increased sweating, and trouble sleeping. Less commonly there may be a feeling of the world spinning, numbness, or muscle pains. Symptoms generally resolve after a short period of time. There is tentative evidence that discontinuation of antipsychotics can result in psychosis. It may also result in reoccurrence of the condition that is being treated. Rarely tardive dyskinesia can occur when the medication is stopped. Deaths In April 2014, it was reported that 21 Japanese people who had received shots of the long-acting injectable<unk>  to date had died, out of 10,700 individuals prescribed the drug.
