Hypotension and circulatory collapse should be treated with appropriate measures such as intravenous fluids. If sympathomimetic agents are used for vascular support, epinephrine and dopamine should not be used, since beta stimulation combined with α 1 antagonism associated with Ziprasidone may worsen hypotension. Similarly, it is reasonable to expect that the alpha-adrenergic-blocking properties of bretylium might be additive to those of Ziprasidone, resulting in problematic hypotension. Do not start, stop, or change the dosage of any medicines without your doctor's approval. QT prolongation and arrhythmia. Hypokalemia may result from diuretic therapy, diarrhea, and other causes.
This medication can cause birth defects, according to animal studies, although this side effect has not been confirmed in humans. If you miss a dose, take it as soon as you remember.

Ziprasidone is primarily cleared via three metabolic routes to yield four major circulating metabolites, benzisothiazole BITP sulphoxide, BITP-sulphone, Ziprasidone sulphoxide, and S-methyldihydroZiprasidone. Approximately 20% of the dose is excreted in the urine, with approximately 66% being eliminated in the feces. Unchanged Ziprasidone represents about 44% of total drug-related material in serum. In vitro studies using human liver subcellular fractions indicate that S-methyldihydroZiprasidone is generated in two steps. These studies indicate that the reduction reaction is mediated primarily by chemical reduction by glutathione as well as by enzymatic reduction by aldehyde oxidase and the subsequent methylation is mediated by thiol methyltransferase. In vitro studies using human liver microsomes and recombinant enzymes indicate that CYP3A4 is the major CYP contributing to the oxidative metabolism of Ziprasidone. CYP1A2 may contribute to a much lesser extent. Based on in vivo abundance of excretory metabolites, less than one-third of Ziprasidone metabolic clearance is mediated by cytochrome P450 catalyzed oxidation and approximately two-thirds via reduction. There are no known clinically relevant inhibitors or inducers of aldehyde oxidase.
It is essential to periodically monitor serum electrolytes in patients for whom diuretic therapy is introduced during Ziprasidone treatment. Persistently prolonged QTc intervals may also increase the risk of further prolongation and arrhythmia, but it is not clear that routine screening ECG measures are effective in detecting such patients.

Hyperglycemia and diabetes mellitus, in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, have been reported in patients treated with atypical antipsychotics. There have been few reports of hyperglycemia or diabetes in patients treated with Ziprasidone hydrochloride. Although fewer patients have been treated with Ziprasidone hydrochloride, it is not known if this more limited experience is the sole reason for the paucity of such reports. Assessment of the relationship between atypical antipsychotic use and glucose abnormalities is complicated by the possibility of an increased background risk of diabetes mellitus in patients with schizophrenia and the increasing incidence of diabetes mellitus in the general population. Given these confounders, the relationship between atypical antipsychotic use and hyperglycemia-related adverse reactions is not completely understood. Precise risk estimates for hyperglycemia-related adverse reactions in patients treated with atypical antipsychotics are not available. Daniel DG, Zimbroff DL, Potkin SG, Reeves KR, Harrigan EP, Lakshminarayanan M May 1999. Neuroleptic Malignant Syndrome NMS has been reported in association with administration of antipsychotic drugs.

Ziprasidone should be used with particular caution in patients with known cardiovascular disease history of myocardial infarction or ischemic heart disease, heart failure or conduction abnormalities cerebrovascular disease, or conditions which would predispose patients to hypotension dehydration, hypovolemia, and treatment with antihypertensive medications. The efficacy of oral Ziprasidone in the treatment of schizophrenia was evaluated in 5 placebo-controlled studies, 4 short-term 4- and 6-week trials and one maintenance trial. All trials were in adult inpatients, most of whom met DSM III-R criteria for schizophrenia. Each study included 2 to 3 fixed doses of Ziprasidone as well as placebo. Four of the 5 trials were able to distinguish Ziprasidone from placebo; one short-term study did not. Although a single fixed-dose haloperidol arm was included as a comparative treatment in one of the three short-term trials, this single study was inadequate to provide a reliable and valid comparison of Ziprasidone and haloperidol.
