Do not administer to patients with cardiac disorders (heart failure, recent myocardial infarction, conduction disorders, bradycardia, etc.), dementia (e.g. Alzheimer's disease), Parkinson's disease and history of neuroleptic malignant syndrome. Administer with caution and carefully monitor use in older patients, patients with hypokalaemia, hypotension, renal or hepatic impairment, history of seizures. May cause: drowsiness (caution when driving/operating machinery), insomnia, headache, extrapyramidal symptoms, agitation, anxiety, orthostatic hypotension, weight gain, hyperprolactinaemia, sexual dysfunction; neuroleptic malignant syndrome (unexplained hyperthermia with neuromuscular disorders), rare but requiring immediate treatment discontinuation. In case of extrapyramidal symptoms, try reducing the dose of risperidone or, if the extrapyramidal symptoms are severe, add biperiden or trihexyphenidyl. Avoid or monitor combination with: central nervous system depressants (opioid analgesics, sedatives, H1 antihistamines, etc.); fluoxetine, paroxetine, sertraline, verapamil (increased plasma concentrations of risperidone); carbamazepine, rifampicin, phenobarbital, phenytoin (decreased plasma concentrations of risperidone); antihypertensive drugs (risk of hypotension); drugs that prolong the QT interval (amiodarone, chloroquine, erythromycin, fluconazole, mefloquine, pentamidine, quinine, etc.). Avoid alcohol during treatment (increased risk of adverse effects). Pregnancy: re-evaluate whether the treatment is still necessary; if it is continued, use the lowest effective dose. Observe the neonate the first few days (risk of agitation, tremors, hypertonia/hypotonia, respiratory difficulties, sleeping disorders, etc.) if the mother was under rd treatment in the 3 trimester. If treatment starts during pregnancy, preferably use haloperidol. Breast-feeding: if absolutely necessary, do not exceed 6 mg daily.
