Serotonin syndrome can range from mild to severe requiring hospitalization to avert fatality. It can also present when abruptly discontinuing a drug such as Clozaril - this action can also flood the CNS with excessive serotonin. The condition can present with single or multiple serotonergic medications, resulting in too much serotonin. Serotonin syndrome or toxicity is a cluster of potentially life-threatening symptoms that is drug-induced. Serotonin Syndrome and Clozaril Withdrawal Ask your local friendly pharmacist about the best way to dispose of medications so you can help protect the environment and the health of people around you. SPECIAL NOTE: As with all leftover, expired, or unused prescription medications, please remember not to flush them or place them in regular garbage containers, and do not otherwise allow them to enter the water system in your community. In Clozaril patients, multi-receptor influences make seizures of particular concern when compared to withdrawal from other antipsychotic medications where seizures can occur but are less prevalent. *Skelly et al.’s 2019 study on abrupt withdrawal from high dose Clozaril, describes the phenomenon of seizure-like activity and other severe reactions as a result of coming off too quickly. Catatonia is associated with abrupt Clozaril withdrawal.Serotonin syndrome can result during Clozapine withdrawal (see below for symptoms of serotonin syndrome in detail) 11,12,13,14,24.Excessive salivation (placing a towel on the pillow is recommended at night) 1.Cardiovascular issues (i.e., tachycardia, blood pressure fluctuations) 1,15.Irregular WBC (white blood cell) count, must be monitored while taking Clozaril and for at least 4 weeks after discontinuation 1,15.Return of psychotic symptoms, high risk of relapse if withdrawal is abrupt 6,9.Severe, abnormal movements such as lurching gait, muscle spasms 7.Newly emerging psychosis in persons with no psychiatric history of such symptoms 10.Clozaril withdrawal symptoms can include: Gradual cessation is recommended to help alleviate this phenomenon. People taking Risperidone for schizophrenia more commonly experience insomnia, while those taking it for bipolar mania are more likely to experience tiredness.In the vast majority of cases, abrupt Clozaril withdrawal is not recommended as it will produce the most severe withdrawal responses. Risperidone (Risperdal) - has been known to cause both tiredness and insomnia depending on the individual.Aripiprazole (Abilify) - sedation is a common side effect. Olanzapine (Zyprexa) - sedation is a common side effect.Quetiapine (Seroquel) - known for extreme sedation and sometimes prescribed for anxiety or sleep disorders.Tolerance to the sedating effect of these drugs may develop during treatment and withdrawal may result in insomnia.Ĭommonly prescribed atypical antipsychotics include: The atypical, or second generation, antipsychotics are less prone to inducing sedation although some atypical antipsychotic drugs are still associated with extreme tiredness and may shift sleep patterns. Chlorpromazine - known for both extreme sedation and anti-anxiety properties.Tolerance to the sedating effect of these drugs may develop during treatment.Įxamples of typical antipsychotics include: Sleep cycles, including REM-sleep, are not altered by antipsychotics, although total sleep time may increase. Typical antipsychotic medications also tend to decrease muscular actions created by psychiatric disorders, like anxiety and obsessive-compulsive disorder, which also may improve sleep. Most typical, or first-generation, antipsychotics have sedating effects. How sedating an antipsychotic is depends on dose and type.
