Very common (>10% incidence) adverse effects include: * Headache * Ejaculation failure * Insomnia * Dizziness Common (1–10% incidence) adverse effects include: * Urine that tests positive for red and/or white blood cells * Sedation (causes less sedation than most antipsychotic drugs according to a recent meta-analysis of the efficacy and tolerability of 15 antipsychotic drugs. Causes only slightly and non-significantly more sedation than amisulpride and paliperidone) * Ejaculation disorder * Erectile dysfunction * Orthostatic hypotension * Weight gain (which it seems to possess a similar propensity for causing as quetiapine) Uncommon (0.1–1% incidence) adverse effects include: * Substernal chest pain * Face oedema * Influenza-like illness * Neck rigidity * Pallor * Peripheral vascular disorder * syncope * Torsades de pointes * Vasodilation * Suicide attempt * Amnesia * Anxiety * Ataxia * Confusion * Incoordination * Libido decreased * Libido increased * Miosis * Nystagmus * Personality disorder * Psychosis * Reflexes decreased * Reflexes increased * Stupor * Suicidal tendency * Urinary retention * Vertigo * Diabetes mellitus * Abnormal stools * Gastritis * Gingivitis * Glossitis * Increased appetite * Mouth ulceration * Rectal disorder * Rectal haemorrhage * Stomatitis * Tongue disorder * Ulcerative stomatitis * Anaemia * Ecchymosis * Hypochromic anaemia * Leukopenia * Hyperglycaemia * Hyperlipemia * Oedema * Bone pain * Myasthenia * Twitching * Bronchitis * Hyperventilation * Pneumonia * Sinusitis * Furunculosis * Herpes simplex * Nail disorder * Psoriasis * Pustular Rash * Skin discolouration * Skin hypertrophy * Skin ulcer * Abnormal vision * Keratoconjunctivitis * Lacrimation disorder * Otitis externa * Pupillary disorder * Taste perversion * Anorgasmia * Penis disorder (gs) * Urinary urgency * Hyperprolactinaemia (which it seems to cause with a higher propensity than most other atypical antipsychotics do) * Seizures * Galactorrhoea Rare (<0.1% incidence) adverse effects include: * Neuroleptic malignant syndrome * Tardive dyskinesia Unknown frequency adverse events include: * Extrapyramidal side effects (EPSE; e.g. dystonia, akathisia, muscle rigidity, parkinsonism, etc. These adverse effects are probably uncommon/rare according to a recent meta-analysis of the efficacy and tolerability of 15 antipsychotic drugs which found it had the 2nd lowest effect size for causing EPSE) * Venous thromboembolism * QT interval prolongation (probably common; in a recent meta-analysis of the efficacy and tolerability of 15 antipsychotic drugs it was found to be the most prone to causing QT interval prolongation)
