Ziprasidone, sold under the brand name Geodon among others, is an atypical antipsychotic used to treat schizophrenia and bipolar disorder.[5] It may be used by mouth and by injection into a muscle (IM).[5] The IM form may be used for acute agitation in people with schizophrenia.[5]

Common side effects include tremors, tics, dizziness, dry mouth, restlessness, nausea, and mild sedation.[6][7] Although it can also cause weight gain, the risk is much lower than for other atypical antipsychotics.[8] How it works is not entirely clear but is believed to involve effects on serotonin and dopamine in the brain.[5]

Ziprasidone was approved for medical use in the United States in 2001.[5] The pills are made up of the hydrochloride salt, ziprasidone hydrochloride. The intramuscular form is the mesylate, ziprasidone mesylate trihydrate, and is provided as a lyophilized powder. In 2020, it was the 282nd most commonly prescribed medication in the United States, with more than 1 million prescriptions.[9][10]
