Newcomer JW, These effects range from relatively minor tolerability issues (e.g., mild sedation or dry mouth) to very unpleasant (e.g., constipation, akathisia, sexual dysfunction) to painful (e.g., acute dystonias) to disfiguring (e.g., weight gain, tardive dyskinesia) to life-threatening (e.g., myocarditis, agranulocytosis). Sharma SG. Switch to an antipsychotic with a different adverse effect profile. Decreasing the antipsychotic dose is the first‐choice management strategy for anticholinergic side effects. 33. Don't miss a single issue. Haddad PM, 2010 Mar 1;81(5):617-622. They can include: Note that priapism requires urgent medical attention. We will revise it in 2023. In: Haddad PM, Dursun S, Deakin B, eds. McGrath JJ. Many psychiatrists who have tried antipsychotics have experienced akathisia, and a number have said it was close to the worst experience of their lives. A double-blind comparison with chlorpromazine. All rights Reserved. There is insufficient long-term clinical information on this medication to include it in this review. 1. Cochrane Database Syst Rev. Get Permissions, Access the latest issue of American Family Physician. Also, as a class, the older first-generation antipsychotics are more likely to be associated with movement disorders, but this is primarily true of medications that bind tightly to dopaminergic neuroreceptors, such as haloperidol, and less true of medications that bind weakly, such as chlorpromazine. Miscellaneous treatments for neuroleptic-induced tardive dyskinesia. 39. Environmental Science and Pollution Research. Newcomer JW. Kirkwood G, The use of antipsychotic medications entails a difficult trade-off between the benefit of alleviating psychotic symptoms and the risk of troubling, sometimes life-shortening adverse effects. Additional risk factors include pre‐existing rigidity26 and AIDS27, 28. But more modern atypical antipsychotics (also called “second-generation”) can also produce side effects. Treatment options include decreasing or dividing doses or switching to a medication with a lesser antiadrenergic effect.6. 2007;176(11):1613]. In all reported cases, reducing the dose or discontinuing the causative medication was effective in ending the uncontrollable behavior within weeks228, 233, 234. Although FGAs and SGAs can cause these problems, risk is variable—the greatest risk is with clozapine and olanzapine. Hallmarks of the syndrome are fever, autonomic instability, rigidity and altered mental status, associated with leukocytosis and elevated creatine phosphokinase. If a baseline prolactin was obtained, and the elevation in prolactin appears clearly related to the antipsychotic, further workup is likely not necessary. Dose reduction is not an effective approach to clozapine‐associated neutropenia224. Barnes TR, Prevention of orthostatic hypotension relies on antipsychotic choice, gradual titration, and dosing distributed throughout the day (in order to minimize peak levels)175. Valbenazine for tardive dyskinesia: a systematic review of the efficacy and safety profile for this newly approved novel medication – what is the number needed to treat, number needed to harm and likelihood to be helped or harmed? Autism spectrum disorder and pupillometry: A systematic review and meta-analysis. Brooks SJ, Benzodiazepines are also thought to be effective in treating dystonias23, 24. 41. According to FDA guidelines, the medication should be stopped if the white blood cell count drops below 3,000 cells per mm3 (3.00 × 109 per L) or the ANC level below 1,500 cells per mm3. Consensus development conference on antipsychotic drugs and obesity and diabetes. Saunders CS, Explains what antipsychotics are used for, how the medication works, possible side effects and information about withdrawal. There has also been concern that elevated prolactin levels may be partly responsible for the observed increase in breast cancer rate among women with schizophrenia165, though evidence is far from conclusive, due to multiple associated lifestyle and metabolic factors166. Schneeweiss S, It appears to be much less common with other SGAs, but has been reported with the use of olanzapine and ziprasidone (Geodon) at high dosages.6. / Journals 1999;156(11):1835–1836. FGAs with lower potency dopamine D2 neuroreceptor blockade (Table 1) are no more likely than most SGAs to cause extrapyramidal symptoms. While this might be right in some cases, it is almost certainly wrong in most cases. See our page on taking antipsychotics safely for more information. 23. This has been known to cause sudden death in extreme cases. Risk factors include use of high dose or rapid administration, thioridazine or butyrophenone antipsychotics, and pre‐existing hypertension or ischemic heart disease188, 190, 191. Although it is a common side effect and a frequently cited reason for medication non‐adherence, the management of sedation has not been widely studied. 18. Development of prescribing safety indicators related to mental health disorders and medications: Modified e‐Delphi study. Mind Infoline is closed right now, for support visit our out of hours page. Several other approaches to akathisia have been explored, but have very limited empirical support. Dystonic reactions are spastic contractions of the muscles, including oculogyric crisis, retrocollis, torticollis, trismus, opisthotonos, or laryngospasm. Evidence suggests that adverse effects are not the main reason why individuals discontinue an antipsychotic medication255.
