#13. In these studies, the most commonly observed adverse reactions associated with the use of intramuscular ziprasidone (incidence of 5% or greater) and observed at a rate on intramuscular ziprasidone (in the higher dose groups) at least twice that of the lowest intramuscular ziprasidone group were headache (13%), nausea (12%), and somnolence (20%). Steady-state concentrations are achieved within one to three days of dosing. Add 1.2 mL of Sterile Water for Injection to the vial and shake vigorously until all the drug is dissolved. Titration within the range of 4080 mg twice daily (in 20 mg twice daily increments) was permitted for the duration of the study. This material is provided for educational purposes only and is not intended for medical advice, diagnosis or treatment. Positive results were obtained in both the in vitro mammalian cell gene mutation assay and the in vitro chromosomal aberration assay in human lymphocytes. Increased prolactin levels were also observed in animal studies with this compound, and were associated with an increase in mammary gland neoplasia in mice; a similar effect was not observed in rats [see Nonclinical Toxicology (13.1)]. Ziprasidone may antagonize the effects of levodopa and dopamine agonists. The safety and effectiveness of Geodon have not been established in pediatric patients. In the second phase of the trial, ECGs were obtained at the time of maximum plasma concentration while the drug was co-administered with an inhibitor of the CYP4503A4 metabolism of the drug. Dystonia - Class Effect: Symptoms of dystonia, prolonged abnormal contractions of muscle groups, may occur in susceptible individuals during the first few days of treatment. To administer a 10 mg dose, draw up 0.5 mL of the reconstituted solution. The recommended dose is 10 mg to 20 mg administered as required up to a maximum dose of 40 mg per day. Lorazepam and haloperidol can be delivered in the same syringe, whereas lorazepam and loxapine will require 2 separate injections. Hypokalemia (and/or hypomagnesemia) may increase the risk of QT prolongation and arrhythmia. The occurrence of rash was related to dose of ziprasidone, although the finding might also be explained by the longer exposure time in the higher dose patients. Over 325 of these subjects participated in trials involving the administration of multiple doses. Although disturbances such as galactorrhea, amenorrhea, gynecomastia, and impotence have been reported with prolactin-elevating compounds, the clinical significance of elevated serum prolactin levels is unknown for most patients. Reconstitution of vial: Using aseptic technique, add 1.2 mL of Sterile Water for Injection, USP to the single-dose vial and shake vigorously until all the drug is dissolved. Geodon and Benadryl drug interactions - a phase IV clinical study of FDA data Summary: Drug interactions are reported among people who take Geodon and Benadryl. The developmental no effect dose was 10 mg/kg/day (equivalent to the MRHD based on a mg/m2 body surface area). Approximately 6.5% (18/279) of ziprasidone-treated patients in short-term, placebo-controlled studies discontinued treatment due to an adverse reaction, compared with about 3.7% (5/136) on placebo. In this set of clinical trials, weight gain was reported as an adverse reaction in 0.4% and 0.4% of ziprasidone and placebo patients, respectively. Low serum potassium and magnesium should be replaced before proceeding with treatment. My preferred agitation regimen is the following: 1) Known or suspected psychosis: 5mg Droperidol +/- 5-10 mg Versed, generally IM pending IV access--takes 5-10 min. Because of ziprasidone's dose-related prolongation of the QT interval and the known association of fatal arrhythmias with QT prolongation by some other drugs, ziprasidone is contraindicated: Pharmacokinetic/pharmacodynamic studies between ziprasidone and other drugs that prolong the QT interval have not been performed. Dopamine Epinephrine (Adrenalin) Esmolol (Brevibloc) Furosemide (Lasix) Heparin Insulin (regular) Lidocaine (Xylocaine) Lorazepam (Ativan) Magnesium . Based on in vitro studies utilizing human liver enzymes, ziprasidone is not a substrate for CYP1A2; smoking should therefore not have an effect on the pharmacokinetics of ziprasidone. Conditions that lower the seizure threshold may be more prevalent in a population of 65 years or older. In a second 3-week placebo-controlled trial (n=205), the dose of ziprasidone was 40 mg twice daily on Day 1. When deciding among the alternative treatments available for the condition needing treatment, the prescriber should consider the finding of ziprasidone's greater capacity to prolong the QT/QTc interval compared to several other antipsychotic drugs [see Warnings and Precautions (5.3)]. In long-term (at least 1 year), placebo-controlled, flexible-dose studies in schizophrenia, the mean change from baseline in random total cholesterol for ziprasidone 2040 mg BID was +2.5 mg/dL (N=14); for ziprasidone 6080 mg BID was -19.7 mg/dL (N=10); and for placebo was -28.0 mg/dL (N=9). There are no known clinically relevant inhibitors or inducers of aldehyde oxidase. The efficacy of intramuscular ziprasidone in the management of agitated schizophrenic patients was established in two short-term, double-blind trials of schizophrenic subjects who were considered by the investigators to be "acutely agitated" and in need of IM antipsychotic medication. Adverse reaction reports not listed above that have been received since market introduction include rare occurrences of the following : Cardiac Disorders: Tachycardia, torsade de pointes (in the presence of multiple confounding factors), [see Warnings and Precautions (5.3)]; Digestive System Disorders: Swollen tongue; Reproductive System and Breast Disorders: Galactorrhea, Priapism; Nervous System Disorders: Facial droop, Neuroleptic malignant syndrome, Serotonin syndrome (alone or in combination with serotonergic medicinal products), Tardive dyskinesia; Psychiatric Disorders: Insomnia, mania/hypomania; Skin and subcutaneous Tissue Disorders: Allergic reaction (such as allergic dermatitis, angioedema, orofacial edema, urticaria), Rash, Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS); Urogenital System Disorders: Enuresis, Urinary incontinence; Vascular Disorders: Postural hypotension, Syncope. However, the syndrome can develop, although much less commonly, after relatively brief treatment periods at low doses. There was no evidence to suggest that these developmental effects were secondary to maternal toxicity. Ziprasidone has not been evaluated or used to any appreciable extent in patients with a recent history of myocardial infarction or unstable heart disease. Proliferative changes in the pituitary and mammary glands of rodents have been observed following chronic administration of other antipsychotic agents and are considered to be prolactin-mediated. Approximately 20% of the dose is excreted in the urine, with approximately 66% being eliminated in the feces. 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. Protect from light. DRESS consists of a combination of three or more of the following: cutaneous reaction (such as rash or exfoliative dermatitis), eosinophilia, fever, lymphadenopathy and one or more systemic complications such as hepatitis, nephritis, pneumonitis, myocarditis, and pericarditis. Chemically, ziprasidone mesylate trihydrate is 5-[2-[4-(1,2-benzisothiazol-3-yl)-1-piperazinyl]ethyl]-6-chloro-1,3-dihydro-2H-indol-2-one, methanesulfonate, trihydrate. After a 3-day single-blind placebo run-in, subjects were randomized to one of 3 fixed doses of ziprasidone (20 mg, 40 mg, or 80 mg twice daily) or placebo and observed for relapse. A reaction was considered treatment emergent if it occurred for the first time or worsened while receiving therapy following baseline evaluation. The BARS is a seven point scale with scores ranging from 1 (difficult or unable to rouse) to 7 (violent, requires restraint). Metabolism and Elimination: Although the metabolism and elimination of IM ziprasidone have not been systematically evaluated, the intramuscular route of administration would not be expected to alter the metabolic pathways. It is generally not recommended to mix Geodon and Ativan in the same syringe, as there is a potential for interaction between the two medications. There was no effect on fertility at 40 mg/kg/day (2 times the MRHD based on mg/m2 body surface area). The mean increase in QTc from baseline for ziprasidone ranged from approximately 9 to 14 msec greater than for four of the comparator drugs (risperidone, olanzapine, quetiapine, and haloperidol), but was approximately 14 msec less than the prolongation observed for thioridazine. Can you mix geodon and lorazepam in the same syringe? Drug class: Atypical antipsychotics. Ziprasidone was significantly superior to placebo in time to relapse, with no significant difference between the different dose groups. Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. Undesirable alterations in lipids have been observed in patients treated with atypical antipsychotics. The premarketing experience for ziprasidone did not reveal an excess risk of mortality for ziprasidone compared to other antipsychotic drugs or placebo, but the extent of exposure was limited, especially for the drugs used as active controls and placebo. Some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization. The developmental no-effect dose is 5 mg/kg/day (0.2 times the MRHD based on mg/m2 body surface area). This possibility needs to be considered in deciding among alternative drug products [see Indications and Usage (1)]. Upon appearance of rash for which an alternative etiology cannot be identified, ziprasidone should be discontinued. In premarketing trials involving more than 5400 patients and/or normal subjects, accidental or intentional overdosage of oral ziprasidone was documented in 10 patients. If a patient requires antipsychotic drug treatment after recovery from NMS, the potential reintroduction of drug therapy should be carefully considered. . A no-effect level was not established for these effects. In addition, patients were required to have a score of 3 or more on at least 3 of the following items of the PANSS: anxiety, tension, hostility and excitement. Two meds that are Y site compatible may not necessarily be compatible mixed in an IM syringe. In addition, instruct patients to report symptoms such as dizziness, palpitations, or syncope to the prescriber [see Warnings and Precautions (5.3)]. Antipsychotic drugs (which include GEODON) may cause somnolence, postural hypotension, and motor and sensory instability, which could lead to falls and, consequently, fractures or other injuries. Given these confounders, the relationship between atypical antipsychotic use and hyperglycemia-related adverse reactions is not completely understood. Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS). Distributed by Table 13 enumerates the incidence, rounded to the nearest percent, of treatment-emergent adverse reactions that occurred during acute therapy with intramuscular ziprasidone in 1% or more of patients. Symptoms of schizophrenia include: Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status, and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac dysrhythmia). Acute Treatment of Agitation in Schizophrenia. Somnolence led to discontinuation in 0.3% of the patients in short-term clinical trials in adults. Ziprasidone should be discontinued in patients who are found to have persistent QTc measurements >500 msec [see Warnings and Precautions (5.3)]. 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). This combination works faster than using either drug alone. In premarketing trials with ziprasidone, about 5% of patients developed rash and/or urticaria, with discontinuation of treatment in about one-sixth of these cases. Ziprasidone's activity is primarily due to the parent drug. Dystonic symptoms include: spasm of the neck muscles, sometimes progressing to tightness of the throat, swallowing difficulty, difficulty breathing, and/or protrusion of the tongue. for Injection Contains 10 of NDC 0049-1203-01, Geodon for Injection These two drugs are compatible in syringe and should be mixed so that only one injection is needed. Chronic antipsychotic treatment should generally be reserved for patients who suffer from a chronic illness that (1) is known to respond to antipsychotic drugs, and (2) for whom alternative, equally effective, but potentially less harmful treatments are not available or appropriate. Instruct patients to report to their health care provider at the earliest onset any signs or symptoms that may be associated with Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) or with severe cutaneous adverse reactions, such as Stevens-Johnson syndrome [see Warnings and Precautions (5.5)]. In the double-blind randomization period, 127 subjects were treated with ziprasidone, and 112 subjects were treated with placebo. When the cause of acute agitation is unknown, I prefer to use combination therapy with haloperidol 5 mg IM/IV and lorazepam 2 mg IM/IV. Advise patients that there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to GEODON during pregnancy [see Use in Specific Populations (8.1)]. Monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately. But the LSD will likely not do anything on account of Geodon's high affinity blockade of the 5HT2a receptor. The results of the oral ziprasidone trials in adult bipolar I disorder, manic/mixed episode follow: in a 3-week placebo-controlled trial (n=210), the dose of ziprasidone was 40 mg twice daily on Day 1 and 80 mg twice daily on Day 2. Ziprasidone is a psychotropic agent that is chemically unrelated to phenothiazine or butyrophenone antipsychotic agents. Extrapyramidal Symptoms (EPS) - The incidence of reported EPS (which included the adverse reaction terms extrapyramidal syndrome, hypertonia, dystonia, dyskinesia, hypokinesia, tremor, paralysis and twitching) for ziprasidone-treated patients in the short-term, placebo-controlled schizophrenia trials was 14% vs. 8% for placebo. Single-dose vials require reconstitution prior to administration. As with other antipsychotic drugs and placebo, sudden unexplained deaths have been reported in patients taking ziprasidone at recommended doses. In the trial, ECGs were obtained at the time of maximum plasma concentration following two injections of ziprasidone (20 mg then 30 mg) or haloperidol (7.5 mg then 10 mg) given four hours apart. Data sources include IBM Watson Micromedex (updated 2 Apr 2023), Cerner Multum (updated 17 Apr 2023), ASHP (updated 10 Apr 2023) and others. None of these adverse reactions occurred individually at an incidence greater than 10% in bipolar mania trials. In patients who do require chronic treatment, the smallest dose and the shortest duration of treatment producing a satisfactory clinical response should be sought. A study was conducted in stable chronic or subchronic (CGI-S 5 at baseline) schizophrenic inpatients (n=294) who had been hospitalized for not less than two months. The BPRS psychosis cluster (conceptual disorganization, hallucinatory behavior, suspiciousness, and unusual thought content) is considered a particularly useful subset for assessing actively psychotic schizophrenic patients. Prolongation of the QTc interval is associated in some other drugs with the ability to cause torsade de pointes-type arrhythmia, a potentially fatal polymorphic ventricular tachycardia, and sudden death. The other patient had a QTc of 391 msec at the end of treatment with ziprasidone and upon switching to thioridazine experienced QTc measurements of 518 and 593 msec. When taking any two medications, consider this in addition to the fact that they have different mechanisms of action. When meds are run together at a Y site, there is actually very little surface area of mixture between the two. An additive effect of ziprasidone and other drugs that prolong the QT interval cannot be excluded. Patients with a pre-existing low WBC or a history of drug induced leukopenia/neutropenia should have their complete blood count (CBC) monitored frequently during the first few months of therapy and should discontinue GEODON at the first sign of decline in WBC in the absence of other causative factors. Each mL of reconstituted solution contains 20 mg ziprasidone. Answer (1 of 3): Generally, any two antipsychotics can be taken together. Subscribe to Drugs.com newsletters for the latest medication news, new drug approvals, alerts and updates. Pooled data from short-term, placebo-controlled studies in schizophrenia and bipolar disorder are presented in Tables 58. There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to atypical antipsychotics, including GEODON, during pregnancy. In animal studies, ziprasidone administration to pregnant rats and rabbits during organogenesis caused developmental toxicity at doses similar to recommended human doses, and was teratogenic in rabbits at 3 times the maximum recommended human dose (MRHD). Available for Android and iOS devices. The primary endpoint in this study was time to recurrence of a mood episode (manic, mixed or depressed episode) requiring intervention, which was defined as any of the following: discontinuation due to a mood episode, clinical intervention for a mood episode (e.g., initiation of medication or hospitalization), or Mania Rating Scale score 18 or a MADRS score 18 (on 2 consecutive assessments no more than 10 days apart). Geodon Injection Dosage and Administration Acute Treatment of Agitation in Schizophrenia Intramuscular Dosing The recommended dose is 10 mg to 20 mg administered as required up to a maximum dose of 40 mg per day. no its not good to mix any drugs together in a syringe inless its in a IV bag mixed by a professional but deffinitly dont mix in a single syringe. 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. Ziprasidone was shown to increase time to copulation in Sprague-Dawley rats in two fertility and early embryonic development studies at doses of 10 to 160 mg/kg/day (0.5 to 8 times the MRHD of 200 mg/day based on mg/m2 body surface area). The Brief Psychiatric Rating Scale (BPRS) and the Positive and Negative Syndrome Scale (PANSS) are both multi-item inventories of general psychopathology usually used to evaluate the effects of drug treatment in schizophrenia. If you must take both medications, it is recommended to do so at least an hour apart to avoid any . Bipolar Disorder During a 6-month placebo-controlled bipolar maintenance study in adults with ziprasidone as an adjunct to lithium or valproate, the incidence of clinically significant weight gain ( 7% of body weight) during the double-blind period was 5.6% for both ziprasidone and placebo treatment groups who completed the 6 months of observation for relapse. In vitro studies using human liver microsomes and recombinant enzymes indicate that CYP3A4 is the major CYP contributing to the oxidative metabolism of ziprasidone. Of the total number of subjects in clinical studies of ziprasidone, 2.4 percent were 65 and over. and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). PREMIERProRx is a registered trademark of Premier Healthcare Alliance, L.P., used under license. These patients include: (1) 4331 patients who participated in multiple-dose trials, predominantly in schizophrenia, representing approximately 1698 patient-years of exposure as of February 5, 2000; and (2) 472 patients who participated in bipolar mania trials representing approximately 133 patient-years of exposure. Hypotension and circulatory collapse should be treated with appropriate measures such as intravenous fluids. Long-standing hyperprolactinemia when associated with hypogonadism may lead to decreased bone density. Therefore, ziprasidone should not be given with: Ziprasidone is contraindicated in individuals with a known hypersensitivity to the product. Aspiration pneumonia is a common cause of morbidity and mortality in elderly patients, in particular those with advanced Alzheimer's dementia. An analysis for dose response in the schizophrenia 4-study pool revealed an apparent relation of adverse reaction to dose for the following reactions: asthenia, postural hypotension, anorexia, dry mouth, increased salivation, arthralgia, anxiety, dizziness, dystonia, hypertonia, somnolence, tremor, rhinitis, rash, and abnormal vision. Applies to: Ativan (lorazepam) and Zyprexa (olanzapine) Ask your doctor before using LORazepam together with OLANZapine. Rather, ziprasidone should be avoided in patients with histories of significant cardiovascular illness, e.g., QT prolongation, recent acute myocardial infarction, uncompensated heart failure, or cardiac arrhythmia. The following adverse reactions have been identified during post-approval use of GEODON. Can you mix geodon and lorazepam in the same syringe? Ziprasidone is a medication that works in the brain to treat schizophrenia. Ziprasidone use should be avoided in combination with other drugs that are known to prolong the QTc interval [see Contraindications (4.1) and Drug Interactions (7.4)]. Feb 15, 2021 A grizzled LPN veteran taught me a nice little trick, pull up your haldol first in the syringe and inject it into your Ativan vial, then draw both of them up. You can mix them, yes. In clinical trials with oral ziprasidone, the electrocardiograms of 2/2988 (0.06%) patients who received GEODON and 1/440 (0.23%) patients who received placebo revealed QTc intervals exceeding the potentially clinically relevant threshold of 500 msec. The conditions and duration of treatment with ziprasidone included open-label and double-blind studies, inpatient and outpatient studies, and short-term and longer-term exposure. Some people, especially the elderly, may also experience impairment in thinking, judgment, and motor coordination. Ziprasidone was significantly more effective than placebo in reduction of the MRS total score and the CGI-S score. Adverse reactions are further categorized by body system and listed in order of decreasing frequency according to the following definitions: Frequent - adverse reactions occurring in at least 1/100 patients (1.0% of patients) (only those not already listed in the tabulated results from placebo-controlled trials appear in this listing); Infrequent - adverse reactions occurring in 1/100 to 1/1000 patients (in 0.11.0% of patients). While the clinical trials did not reveal any tendency for drug-seeking behavior, these observations were not systematic and it is not possible to predict on the basis of this limited experience the extent to which ziprasidone will be misused, diverted, and/or abused once marketed. Contents should be mixed thoroughly by gently inverting the . The types of relapse events observed included depressive, manic, and mixed episodes. Geodon In clinical trial and postmarketing experience, events of leukopenia/neutropenia have been reported temporally related to antipsychotic agents. Applies to: Ativan (lorazepam) and Geodon (ziprasidone) Using LORazepam together with ziprasidone may increase side effects such as dizziness, drowsiness, confusion, and difficulty concentrating. In the patient taking the largest confirmed amount, 3,240 mg, the only symptoms reported were minimal sedation, slurring of speech, and transitory hypertension (200/95). Patients with severe neutropenia (absolute neutrophil count <1000/mm3) should discontinue GEODON and have their WBC followed until recovery. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The mechanism of action of ziprasidone in the treatment of the listed indications could be mediated through a combination of dopamine type 2 (D2) and serotonin type 2 (5HT2) antagonism. There was a reproducible mutagenic response in the Ames assay in one strain of S. typhimurium in the absence of metabolic activation. After intramuscular administration of single doses, peak serum concentrations typically occur at approximately 60 minutes post-dose or earlier and the mean half-life (T) ranges from two to five hours. COMPATIBILITY OF DRUGS COMBINED IN A SYRINGE. Intravenous access should be established, and gastric lavage (after intubation, if patient is unconscious) and administration of activated charcoal together with a laxative should be considered. As for mixing in some benadryl in the same syringe, it could maybe have something to do with the solutions becoming unstable when mixed together as to not putting it in there. Less than one-third of ziprasidone metabolic clearance is mediated by cytochrome P450 catalyzed oxidation. no its not good to mix any drugs together in a syringe inless its in a IV bag mixed by a professional but deffinitly dont mix in a single syringe. For current full prescribing information, please visit www.pfizer.com. Pooled data from short-term, placebo-controlled studies in schizophrenia and bipolar disorder are presented in Tables 910. We comply with the HONcode standard for trustworthy health information. There was no statistically significant change in the urinary dextromethorphan/dextrorphan ratio. Titration within the range of 4080 mg twice daily (in 20 mg twice daily increments) was permitted for the duration of study (beginning on Day 2). This question came up when I was asked why Haldol, Ativan, and Benadryl can't go in the same syringe. The management of NMS should include: (1) immediate discontinuation of antipsychotic drugs and other drugs not essential to concurrent therapy; (2) intensive symptomatic treatment and medical monitoring; and (3) treatment of any concomitant serious medical problems for which specific treatments are available. A pharmacokinetic interaction of ziprasidone with valproate is unlikely due to the lack of common metabolic pathways for the two drugs. Ketoconazole, a potent inhibitor of CYP3A4, at a dose of 400 mg QD for 5 days, increased the AUC and Cmax of ziprasidone by about 3540%. A retrospective cohort study from a Medicaid database of 9258 women exposed to antipsychotics during pregnancy did not indicate an overall increased risk for major birth defects. 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. During long-term therapy with ziprasidone, a categorization of patients at baseline on the basis of body mass index (BMI) revealed the greatest mean weight gain and highest incidence of clinically significant weight gain (> 7% of body weight) in patients with low BMI (<23) compared to normal (2327) or overweight patients (>27).
