The Effects of Geodon

Geodon is a prescription drug classified as an atypical anti-psychotic. It contains the generic medicine ziprasidone. Geodon is available as an oral capsule and an injection that is given into the muscle. According to the "2010 Lippincott's Nursing Drug Guide," Geodon oral capsules are given twice a day in doses of 20mg to 80mg. Intramuscular doses of 10mg to 20mg may be given, with a maximum dose of 40mg in a 24-hour period.

Effects in Schizophrenia

Oral Geodon treats some of the symptoms of schizophrenia. It is used to alleviate anger and withdrawal from social situations. Some individuals with schizophrenia are quiet and emotionless. Geodon is also beneficial for these symptoms. The drug may help those with a lack of motivation become more motivated to care for themselves, express themselves and engage in activities around them. Ziprasidone also helps lengthen the period of time between relapses of schizophrenic symptoms.

Effects in Agitation

Intramuscular Geodon is used to treat severe agitation, threatening behaviors, self-harming behaviors and other psychotic behaviors exhibited during acute schizophrenic episodes. It works rapidly to control behavior. The drug manufacturer recommends that intramuscular injections not be given to individuals already taking the oral preparation.

Effects in Bipolar Disorder

Oral Geodon is used to treat acute manic episodes and mixed episodes in bipolar disorder, according to the National Center for Biotechnology Information. Alleviated symptoms include extreme irritation, severe excitement and frenzied behavior. Ziprasidone is also given in combination with valproate or lithium for chronic treatment of bipolar disorder.
