Common side effects include movement problems, sleepiness, dizziness, trouble seeing, constipation, and increased weight. About 9 to 20% of people gained more than 7% of the baseline weight depending on the dose. Serious side effects may include the potentially permanent movement disorder tardive dyskinesia, as well as neuroleptic malignant syndrome, an increased<unk> k of suicide, and high blood sugar levels. In older people with psychosis as a result of dementia, it may increase the<unk> k of death. While atypical antipsychotics appear to have a lower rate of movement problems as compared to typical antipsychotics,<unk>  has a high<unk> k of movement problems among the atypicals. Atypical antipsychotics however are associated with a greater amount of weight gain. Drug interactions * Carbamazepine and other enzyme inducers may reduce plasma levels of<unk> . If a person is taking both carbamazepine and<unk> , the dose of<unk>  will likely need to be increased. The new dose should not be more than twice the patient's original dose. * CYP2D6 inhibitors, such as SSRI medications, may increase plasma levels of<unk>  and those medications. * Since<unk>  can cause hypotension, its use should be monitored closely when a patient is also taking antihypertensive medicines to avoid severe low blood pressure. *<unk>  and its metabolite paliperidone are reduced in efficacy by P-glycoprotein inducers such as St John's wort Discontinuation The British National Formulary recommends a gradual withdrawal when discontinuing antipsychotic treatment to avoid acute withdrawal syndrome or rapid relapse. Some have argued the additional somatic and psychiatric symptoms associated with dopaminergic super-sensitivity, including dyskinesia and acute psychosis, are common features of withdrawal in individuals treated with neuroleptics. This has led some to suggest the withdrawal process might itself be schizomimetic, producing schizophrenia-like symptoms even in previously healthy patients, indicating a possible pharmacological origin of mental illness in a yet unknown percentage of patients currently and previously treated with antipsychotics. This question is unresolved, and remains a highly controversial issue among professionals in the medical and mental health communities, as well as the public. Dementia Older people with dementia-related psychosis are at a higher<unk> k of death if they take<unk>  compared to those who do not. Most deaths are related to heart problems or infections.
