Medical Editor: John P. Cunha, DO, FACOEP
Zyprexa Relprevv (olanzapine) is an atypical antipsychotic prescribed to treat schizophrenia and acute manic episodes associate with bipolar I disorder. Common side effects of Zyprexa Relprevv include agitation or restlessness, constipation, dizziness, drowsiness, weakness, insomnia, nausea, dry mouth, dizziness upon standing (orthostatic hypotension), tremors or shaking, weight gain, or pain where the injection was given. More severe side effects of Zyprexa Relprevv include involuntary movements (tardive dyskinesia), elevated blood sugar (hyperglycemia) in people with diabetes, coma, dementia in the elderly, abnormal menstruation, sexual dysfunction, and breast enlargement.
Dosing of Zyprexa Relprevv ranges from 10-20 mg daily for schizophrenia, and 10-15 mg daily for bipolar I disorder. The maximum dose is 20 mg daily for both schizophrenia and bipolar I disorder. There are several drugs that interact with Zyprexa Relprevv, so the patient should discuss all medications they are taking with the prescribing doctor. There are no adequate studies of Zyprexa Relprevv in pregnant women. Zyprexa Relprevv should only be prescribed to a pregnant woman if the benefits outweigh the unknown risks. Zyprexa Relprevv is excreted in breast milk; therefore it is recommended that nursing mothers not use Zyprexa Relprevv.
Our Zyprexa Relprevv Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

What is Patient Information Overview?
A concise overview of the drug for the patient or caregiver from First DataBank.
Zyprexa Relprevv Overview - Patient Information: Side Effects
To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Olanzapine extended-release injection is designed to release medication slowly over 2 to 4 weeks. If the medication releases too quickly, your drug levels may be too high. Seek immediate medical attention if any of these symptoms of high olanzapine levels occur: very drowsy/hard to wake up, severe dizziness, slowed breathing, new or worsening mental/mood changes (such as confusion, agitation, nervousness, aggression), restlessness, muscle stiffness/spasm, shaking (tremor), unusual weakness, difficulty walking or speaking, balance problems, seizure.
This drug may rarely make your blood sugar level rise, which can cause or worsen diabetes. Weight gain from this drug may increase the risk of this side effect. Tell your doctor immediately if you develop symptoms of high blood sugar such as increased thirst and urination, breath smells fruity, feel very hungry/weak/tired. If you already have diabetes, be sure to check your blood sugar level regularly.
This drug may cause significant weight gain and a rise in your blood cholesterol (or triglyceride) levels, especially in teenagers. These effects, along with diabetes, may increase your risk for developing heart disease. Discuss the risks and benefits of treatment with your doctor. (See also Notes section.)
Tell your doctor immediately if any of these unlikely but serious side effects occur: yellowing of the eyes/skin, severe abdominal pain, difficulty swallowing, signs of infection (such as fever, persistent sore throat), trouble urinating.
This medication may rarely cause a very serious condition called neuroleptic malignant syndrome (NMS). Get medical help right away if you have any of the following symptoms: fever, muscle stiffness/pain/tenderness/weakness, severe tiredness, severe confusion, sweating, fast/irregular heartbeat, dark urine, change in the amount of urine.
Olanzapine may rarely cause a condition known as tardive dyskinesia. In some cases, this condition may be permanent. Tell your doctor immediately if you develop any unusual/uncontrolled movements (especially of the face or tongue).
In rare cases, olanzapine may increase your level of a certain substance made by the body (prolactin). For females, this increase in prolactin may result in unwanted breast milk, missed/stopped periods, or difficulty becoming pregnant. For males, it may result in decreased sexual ability, inability to produce sperm, or enlarged breasts. If you develop any of these symptoms, tell your doctor immediately.
A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Zyprexa Relprevv FDA Prescribing Information: Side Effects
Clinical Trials Experience
The information below for ZYPREXA RELPREVV is derived primarily from a clinical trial database consisting of 2058 patients with approximately 1948 patient years of exposure to ZYPREXA RELPREVV. This database includes safety data from 6 open-label studies and 2 double-blind comparator studies, conducted in patients with schizophrenia or schizoaffective disorder. Additionally, data obtained from patients treated with oral olanzapine are also presented below. Adverse reactions were assessed by the collection of adverse reactions, vital signs, weights, laboratory analytes, ECGs, and the results of physical and ophthalmologic examinations. In the tables and tabulations that follow for ZYPREXA RELPREVV, the MedDRA terminology has been used to classify reported adverse reactions. Data obtained from oral olanzapine studies was reported using the COSTART and MedDRA dictionaries.
The stated frequencies of adverse reactions represent the proportion of individuals who experienced, at least once, a treatment-emergent adverse reaction of the type listed. A reaction was considered treatment emergent if it occurred for the first time or worsened while receiving therapy following baseline evaluation. Reactions listed elsewhere in labeling may not be repeated below. The entire label should be read to gain a complete understanding of the safety profile of ZYPREXA RELPREVV.
The prescriber should be aware that the figures in the tables and tabulations cannot be used to predict the incidence of side effects in the course of usual medical practice where patient characteristics and other factors differ from those that prevailed in the clinical trials. Similarly, the cited frequencies cannot be compared with figures obtained from other clinical investigations involving different treatments, uses, and investigators. The cited figures, however, do provide the prescribing physician with some basis for estimating the relative contribution of drug and nondrug factors to the adverse reaction incidence in the population studied.
Adverse Reactions Associated with Discontinuation of Treatment in a Short-Term, Placebo-Controlled Trial
Overall, there was no difference in the incidence of discontinuation due to adverse reactions between ZYPREXA RELPREVV (4%; 13/306 patients) and placebo (5%; 5/98 patients) in an 8-week trial.
Commonly Observed Adverse Reactions in a Short-Term, Placebo-Controlled Trial
In an 8-week trial, treatment-emergent adverse reactions with an incidence of 5% or greater in at least one of the ZYPREXA RELPREVV treatment groups (210 mg/2 weeks, 405 mg/4 weeks, or 300 mg/2 weeks) and greater than placebo were: headache, sedation, weight gain, cough, diarrhea, back pain, nausea, somnolence, dry mouth, nasopharyngitis, increased appetite, and vomiting.
Adverse Reactions Occurring at an Incidence of 2% or More among ZYPREXA RELPREVV-Treated Patients in a Short- Term, Placebo-Controlled Trial
Table 9 enumerates the incidence, rounded to the nearest percent, of treatment-emergent adverse reactions that occurred in 2% or more of patients treated with ZYPREXA RELPREVV and with incidence greater than placebo who participated in the 8-week, placebo-controlled trial.

Dose Dependency of Adverse Reactions
A dose group difference for oral olanzapine has been observed for fatigue, dizziness, weight gain and prolactin elevation. In a single 8-week randomized, double-blind, fixed-dose study comparing 10 (N=199), 20 (N=200) and 40 (N=200) mg/day of oral olanzapine in adult patients with schizophrenia or schizoaffective disorder, incidence of fatigue (10 mg/day: 1.5%; 20 mg/day: 2.1%; 40 mg/day: 6.6%) was observed with significant differences between 10 vs 40 and 20 vs 40 mg/day. The incidence of dizziness (10 mg/day: 2.6%; 20 mg/day: 1.6%; 40 mg/day: 6.6%) was observed with significant differences between 20 vs 40 mg. Dose group differences were also noted for weight gain and prolactin elevation [see WARNINGS AND PRECAUTIONS].
The following table enumerates the percentage of patients with treatment-emergent extrapyramidal symptoms as assessed by categorical analyses of formal rating scales during acute therapy in a controlled clinical trial comparing oral olanzapine at 3 fixed doses with placebo in the treatment of schizophrenia in a 6-week trial.

Dystonia, Class Effect
Symptoms of dystonia, prolonged abnormal contractions of muscle groups, may occur in susceptible individuals during the first few days of treatment. 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. While these symptoms can occur at low doses, the frequency and severity are greater with high potency and at higher doses of first generation antipsychotic drugs. In general, an elevated risk of acute dystonia may be observed in males and younger age groups receiving antipsychotics; however, events of dystonia have been reported infrequently ( < 1%) with olanzapine use.
Other Adverse Reactions
Local Injection Site Reactions
Eleven ZYPREXA RELPREVV-treated patients (3.6%) and 0 placebo-treated patients experienced treatmentemergent injection-related adverse reactions (injection site pain, buttock pain, injection site mass, induration, injection site induration) in the placebo-controlled database. The most frequently occurring treatment-emergent adverse reaction was injection site pain (2.3% ZYPREXA RELPREVV-treated; 0% placebo-treated).
Other Adverse Reactions Observed During the Clinical Trial Evaluation of Olanzapine for Extended-Release Injectable Suspension
Injection site abscess has been reported in clinical trials with ZYPREXA RELPREVV therapy. Isolated cases required surgical intervention.
Commonly Observed Adverse Reactions During the Clinical Trial Evaluation of Oral Olanzapine
In clinical trials of oral olanzapine monotherapy for the treatment of schizophrenia in adult patients, treatmentemergent adverse reactions with an incidence of 5% or greater in the olanzapine treatment arm and at least twice that of placebo were: postural hypotension, constipation, weight gain, dizziness, personality disorder, and akathisia.
Other Adverse Reactions Observed During the Clinical Trial Evaluation of Oral Olanzapine
Following is a list of treatment-emergent adverse reactions reported by patients treated with oral olanzapine (at multiple doses ≥ 1 mg/day) in clinical trials. This listing is not intended to include reactions (1) already listed in previous tables or elsewhere in labeling, (2) for which a drug cause was remote, (3) which were so general as to be uninformative, (4) which were not considered to have significant clinical implications, or (5) which occurred at a rate equal to or less than placebo. Reactions are classified by body system using the following definitions: frequent adverse reactions are those occurring in at least 1/100 patients; infrequent adverse reactions are those occurring in 1/100 to 1/1000 patients; rare adverse reactions are those occurring in fewer than 1/1000 patients.
Cardiovascular System - Infrequent: cerebrovascular accident, vasodilatation.
Digestive System - Infrequent: abdominal distension, nausea and vomiting, tongue edema; Rare: ileus, intestinal obstruction, liver fatty deposit.
Hemic and Lymphatic System - Infrequent: thrombocytopenia.

Vital Signs and Laboratory Studies
ZYPREXA RELPREVV in Adults: Statistically significant within group mean changes for ZYPREXA RELPREVV, which were also significantly different from placebo, were observed for the following: eosinophils, monocytes, cholesterol, low-density lipoprotein (LDL), triglycerides, and direct bilirubin. There were no statistically significant differences between ZYPREXA RELPREVV and placebo in the incidence of potentially clinically significant changes in any of the laboratory values studied.
Statistically significant within group mean changes for ZYPREXA RELPREVV, which were also significantly different from oral olanzapine (in a 24-week double-blind study), were observed for the following: gammaglutamyltransferase (GGT) and sodium.
From an analysis of the laboratory data in an integrated database of 41 completed clinical studies in adult patients treated with oral olanzapine, high GGT levels were recorded in ≥ 1% (88/5245) of patients.
Statistically significant differences were observed between ZYPREXA RELPREVV and oral olanzapine for the incidence of treatment-emergent low platelet count (0% ZYPREXA RELPREVV vs 1% oral olanzapine); and low total bilirubin (2.8% ZYPREXA RELPREVV vs 0.7% for oral olanzapine). There was a statistically significant difference between ZYPREXA RELPREVV and oral olanzapine in potentially clinically significant changes for high leukocyte count (0% ZYPREXA RELPREVV vs 1% oral olanzapine).
Changes in aminotransferases observed with ZYPREXA RELPREVV treatment were similar to those reported with ZYPREXA treatment. In placebo-controlled ZYPREXA RELPREVV studies, clinically significant ALT elevations ( ≥ 3 times the upper limit of the normal range) were observed in 2.7% (8/291) of patients exposed to olanzapine compared to 3.2% (3/94) of the placebo patients. None of these patients experienced jaundice. In 3 of these patients, liver enzymes reverted to the normal range despite continued treatment, and in 5 cases enzymes values decreased, but were still above the normal range at the end of therapy.
Within the larger premarketing ZYPREXA RELPREVV database of 1886 patients with baseline ALT ≤ 90 IU/L, the incidence of ALT elevation to > 200 IU/L was 0.8%. None of these patients experienced jaundice or other symptoms attributable to liver impairment and most had transient changes that tended to normalize while ZYPREXA RELPREVV treatment was continued.
From an analysis of the laboratory data in an integrated database of 41 completed clinical studies in adult patients treated with oral olanzapine, elevated uric acid was recorded in ≥ 3% (171/4641) of patients.
Olanzapine Monotherapy in Adults: An assessment of the premarketing experience for oral olanzapine revealed an association with asymptomatic increases in ALT, AST, and GGT. Within the original premarketing database of about 2400 adult patients with baseline ALT ≤ 90 IU/L, the incidence of ALT elevations to > 200 IU/L was 2% (50/2381). None of these patients experienced jaundice or other symptoms attributable to liver impairment and most had transient changes that tended to normalize while olanzapine treatment was continued.
In placebo-controlled oral olanzapine monotherapy studies in adults, clinically significant ALT elevations (change from < 3 times the upper limit of normal [ULN] at baseline to ≥ 3 times ULN) were observed in 5% (77/1426) of patients exposed to olanzapine compared to 1% (10/1187) of patients exposed to placebo. ALT elevations ≥ 5 times ULN were observed in 2% (29/1438) of olanzapine-treated patients, compared to 0.3% (4/1196) of placebo-treated patients. ALT values returned to normal, or were decreasing, at last follow-up in the majority of patients who either continued treatment with olanzapine or discontinued olanzapine. No patient with elevated ALT values experienced jaundice, liver failure, or met the criteria for Hy's Rule.
Caution should be exercised in patients with signs and symptoms of hepatic impairment, in patients with preexisting conditions associated with limited hepatic functional reserve, and in patients who are being treated with potentially hepatotoxic drugs.
Oral olanzapine administration was also associated with increases in serum prolactin [see WARNINGS AND PRECAUTIONS], with an asymptomatic elevation of the eosinophil count in 0.3% of patients, and with an increase in CPK.
Comparison of ZYPREXA RELPREVV and oral olanzapine, in a 24 week study, revealed no significant differences on ECG changes. Between-group comparisons for pooled placebo-controlled trials revealed no significant oral olanzapine/placebo differences in the proportions of patients experiencing potentially important changes in ECG parameters, including QT, QTc, and PR intervals. Oral olanzapine use was associated with a mean increase in heart rate of 2.4 beats per minute compared to no change among placebo patients. This slight tendency to tachycardia may be related to olanzapine's potential for inducing orthostatic changes [see WARNINGS AND PRECAUTIONS].
Adverse reactions reported since market introduction that were temporally (but not necessarily causally) related to ZYPREXA therapy include the following: allergic reaction (e.g., anaphylactoid reaction, angioedema, pruritus or urticaria), cholestatic or mixed liver injury, diabetic coma, diabetic ketoacidosis, discontinuation reaction (diaphoresis, nausea, or vomiting), hepatitis, jaundice, neutropenia, pancreatitis, priapism, rash, rhabdomyolysis, and venous thromboembolic events (including pulmonary embolism and deep venous thrombosis). Random cholesterol levels of ≥ 240 mg/dL and random triglyceride levels of ≥ 1000 mg/dL have been reported. Additionally, injection site abscess has been reported in postmarketing reports with ZYPREXA RELPREVV therapy. Isolated cases required surgical intervention.
