NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

WARNING: RISKS FROM CONCOMITANT USE WITH OPIOIDS; ABUSE, MISUSE, AND ADDICTION; and DEPENDENCE AND WITHDRAWAL REACTIONS Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Monitor patients for respiratory depression and sedation [see Warnings and Precautions (5.1), Drug Interactions (7.1)]. The use of benzodiazepines, including midazolam, exposes users to risks of abuse, misuse, and addiction, which can lead to overdose or death.

Abuse and misuse of benzodiazepines commonly involve concomitant use of other medications, alcohol, and/or illicit substances, which is associated with a n increased frequency of serious adverse outcomes. Before prescribing Midazolam Injection and throughout treatment, assess each patient’s risk for abuse, misuse, and addiction [see Warnings and Precautions (5.2)]. The continued use of benzodiazepines may lead to clinically significant physical dependence.

The risks of dependence and withdrawal increase with longer treatment duration and higher daily dose. Although Midazolam Injection is indicated only for intermittent use [see Indications and Usage (1) and Dosage and Administration (2)], if used more frequently than recommended, abrupt discontinuation or rapid dosage reduction of Midazolam Injection may precipitate acute withdrawal reactions, which can be life-threatening. For patients using Midazolam Injection more frequently than recommended, to reduce the risk of withdrawal reactions, use a gradual taper to discontinue Midazolam Injection [see Warnings and Precautions (5.3)].

WARNING: RISKS FROM CONCOMITANT USE WITH OPIOIDS; ABUSE, MISUSE, AND ADDICTION; and DEPENDENCE AND WITHDRAWAL REACTIONS See full prescribing information for complete boxed warning. Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Monitor patients for respiratory depression and sedation.

(5.1, 7.1) The use of benzodiazepines, including midazolam, exposes users to risks of abuse, misuse, and addiction, which can lead to overdose or death. Before prescribing Midazolam Injection and throughout treatment, assess each patient’s risk for abuse, misuse, and addiction. (5.2) Although Midazolam Injection is indicated only for intermitt ent use (1, 2), if used more frequently than recommended, abrupt discontinuation or rapid dosage reduction of Midazolam Injection may precipitate acute withdrawal reactions, which can be lifethreatening.

For patients using Midazolam Injection more frequently than recommended, to reduce the risk of withdrawal reactions, use a gradual taper to discontinue Midazolam Injection. (5.3)

🎯 Indications and Usage 27 words ▾

Midazolam Injection is indicated for the treatment of status epilepticus in adults. Midazolam Injection is a benzodiazepine indicated for the treatment of status epilepticus in adults. (1)

⏱️ Dosage and Administration ~1 min read ▾

Recommended Dose The recommended dose of Midazolam Injection is a single 10 mg dose, administered by intramuscular injection [see Dosage and Administration (2.2)]. Important Administration Instructions Midazolam Injection should be administered by trained personnel who have had adequate training in the recognition and treatment of status epilepticus and first aid/basic airway management. Midazolam Injection is for intramuscular use only as a single dose.

Inject in the mid-outer thigh (vastus lateralis muscle) using the prefilled autoinjector. The Midazolam autoinjector can inject through clothing. Move all objects from in and around the patient’s clothing that may interfere with the injection.

For people who do not have a lot of fat at the mid-outer thigh, bunch up the thigh at the injection site to provide a thicker area for administration. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit [see Dosage Forms and Strengths (3)]. Refer to the illustrated Midazolam Injection Instructions for Use for autoinjector administration instructions.

Monitoring After administration of Midazolam Injection, continuous monitoring of respiratory and cardiac function is recommended until the patient is stabilized. Serious and life-threatening cardiorespiratory adverse reactions, such as hypoventilation, airway obstruction, apnea, and hypotension have been reported with the use of midazolam. Patients should be monitored in a setting that allows for immediate access to resuscitative drugs.

Appropriate resuscitation equipment and personnel trained in their use and skilled in airway management should be available [see Warnings and Precautions (5.4), Adverse Reactions (6.1)]. Observation for signs of cardiorespiratory depression is particularly important in patients with chronic obstructive pulmonary disease (COPD), patients 60 or more years of age, and patients who have received concomitant narcotics or other central nervous system (CNS) depressants. The recommended dose is a single 10 mg dose, administered by intramuscular injection using the prefilled autoinjector.

(2.1) Inject in the mid-outer thigh (vastus lateralis muscle). (2.2) Continuous monitoring of respiratory and cardiac function is recommended. (2.3)

⚠️ Warnings and Cautions ~3 min read ▾

Risks from Concomitant Use with Opioids Concomitant use of benzodiazepines, including Midazolam Injection, and opioids may result in profound sedation, respiratory depression, coma, and death. If a decision is made to use midazolam concomitantly with opioids, monitor patients closely for respiratory depression and sedation [see Drug Interactions (7.1)]. Trained personnel administering Midazolam Injection must have the skills necessary to manage serious cardiorespiratory adverse reactions, including skills in airway management.

Abuse, Misuse, and Addiction The use of benzodiazepines, including Midazolam Injection, exposes users to the risks of abuse, misuse, and addiction, which can lead to overdose or death. Abuse and misuse of benzodiazepines often (but not always) involve the use of doses greater than the maximum recommended dosage and commonly involve concomitant use of other medications, alcohol, and/or illicit substances, which is associated with an increased frequency of serious adverse outcomes, including respiratory depression, overdose, or death [see Drug Abuse and Dependence (9.2)].

Before prescribing Midazolam Injection and throughout treatment, assess each patient’s risk for abuse, misuse, and addiction. Use of Midazolam Injection, particularly in patients at elevated risk, necessitates counseling about the risks and proper use of Midazolam Injection along with monitoring for signs and symptoms of abuse, misuse, and addiction. Do not exceed the recommended dosing frequency; avoid or minimize concomitant use of CNS depressants and other substances associated with abuse, misuse, and addiction (e.g., opioid analgesics, stimulants); and advise patients on the proper disposal of unused drug.

If a substance use disorder is suspected, evaluate the patient and institute (or refer them for) early treatment, as appropriate. Dependence and Withdrawal Reactions After Use of Midazolam Injection More Frequently Than Recommended For patients using Midazolam Injection more frequently than recommended, to reduce the risk of withdrawal reactions, use a gradual taper to discontinue Midazolam Injection (a patient-specific plan should be used to taper the dose). Patients at an increased risk of withdrawal adverse reactions after benzodiazepine discontinuation or rapid dosage reduction include those who take higher dosages, and those who have had longer durations of use.

Acute Withdrawal Reactions The continued use of benzodiazepines may lead to clinically significant physical dependence. Although Midazolam Injection is indicated only for intermittent use [see Indications and Usage (1) and Dosage and Administration (2)], if used more frequently than recommended, abrupt discontinuation or rapid dosage reduction of Midazolam Injection, or administration of flumazenil (a benzodiazepine antagonist) may precipitate acute withdrawal reactions, which can be life-threatening (e.g., seizures) [see Drug Abuse and Dependence (9.3)].

Protracted Withdrawal Syndrome In some cases, benzodiazepine users have developed a protracted withdrawal syndrome with withdrawal symptoms lasting weeks to more than 12 months [see Drug Abuse and Dependence (9.3)]. Risks of Cardiorespiratory Adverse Reactions Serious cardiorespiratory adverse reactions have occurred after administration of midazolam. These have included respiratory depression, airway obstruction, oxygen desaturation, apnea, respiratory arrest and/or cardiac arrest, sometimes resulting in death or permanent neurologic injury.

There have also been rare reports of hypotensive episodes requiring treatment during or after diagnostic or surgical manipulations, particularly in patients with hemodynamic instability. Hypotension occurs more frequently in patients premedicated with a narcotic. The danger of hypoventilation, airway obstruction, or apnea is greater in elderly patients and those with chronic disease states or decreased pulmonary reserve [see Use in Specific Populations (8.5, 8.7)]; patients with C… [Excerpted — this section continues on DailyMed.]

🤒 Adverse Reactions ~2 min read ▾

The following serious adverse reactions are discussed in greater detail in other sections: Risks from Concomitant Use with Opioids [see Warnings and Precautions (5.1)] Abuse, Misuse, and Addiction [see Warnings and Precautions (5.2)] Dependence and Withdrawal Reactions After Use of Midazolam Injection More Frequently Than Recommended [see Warnings and Precautions (5.3)] Risks of Cardiorespiratory Adverse Reactions [see Warnings and Precautions (5.4)] Other Adverse Reactions [see Warnings and Precautions (5.5)] Risks from Concomitant Use of Central Nervous System Depressants [see Warnings and Precautions (5.6)] Impaired Cognitive Function [see Warnings and Precautions (5.7)] Glaucoma [see Warnings and Precautions (5.8)] Neonatal Sedation and Withdrawal Syndrome [see Warnings and Precautions (5.9)] Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The safety of Midazolam Injection has been established by data from an adequate and well-controlled study of a different midazolam injection in adult patients with status epilepticus [see Clinical Studies (14)]. Below is a display of the adverse reactions of midazolam injection in this adequate and well-controlled study. Adverse Reactions in the Controlled Study of Intramuscular Midazolam in Patients with Status Epilepticus In a double-blind, randomized, active-controlled clinical study, 448 patients were assigned to receive intramuscular (IM) midazolam via an autoinjector, and 445 were assigned to receive intravenous (IV) lorazepam.

Approximately 45% of patients were female, and the mean age was 43 years. Patients were administered treatment by a healthcare professional (e.g., paramedic) prior to arrival at a hospital. Table 1 lists the adverse reactions occurring in 2% or more of the IM midazolam-treated patients and at a rate greater than the IV lorazepam-treated patients.

Table 1 Adverse Reactions in 2% or More of IM Midazolam-Treated Patients and More Frequent than in IV Lorazepam-Treated Patients in Out of Hospital Treatment of Status Epilepticus Adverse Reactions in Other Midazolam Studies Midazolam Injection is only indicated for status epilepticus, but for uses other than that for which Midazolam Injection is indicated, fluctuations in vital signs were the most frequently seen findings following parenteral administration of midazolam in adults, and included decreased tidal volume and/or respiratory rate decrease [11% of patients following intramuscular administration], as well as variations in blood pressure and pulse rate.

The majority of serious adverse effects, particularly those associated with oxygenation and ventilation, have been reported when midazolam was administered with other medications capable of depressing the CNS. The incidence of such events was higher in patients undergoing procedures involving the airway without the protective effect of an endotracheal tube (e.g., upper endoscopy and dental procedures). The following additional adverse reactions were reported after intramuscular administration in adults: Headache (1.3%), and local effects at the IM injection site including pain (3.7%), induration (0.5%), redness (0.5%), and muscle stiffness (0.3%).

The most common adverse reactions (incidence >3%) in clinical trials in patients with status epilepticus were upper airway obstruction, agitation, and pyrexia.

🔄 Drug Interactions 216 words ▾

Effect of Concomitant Use of Benzodiazepines and Opioids The concomitant use of benzodiazepines and opioids increases the risk of respiratory depression because of actions at different receptor sites in the CNS that control respiration. Benzodiazepines interact at GABAA sites and opioids interact primarily at mu receptors. When benzodiazepines and opioids are combined, the potential for benzodiazepines to significantly worsen opioid-related respiratory depression exists.

Limit dosage and duration of concomitant use of benzodiazepines and opioids. Monitor patients closely for respiratory depression and sedation. Other CNS Depressants and Alcohol The sedative effect of Midazolam Injection is accentuated by concomitantly administered medication that depresses the central nervous system, particularly opioids (e.g., morphine, meperidine, and fentanyl), secobarbital, and droperidol, and also by alcohol [see Warnings and Precautions (5.1, 5.4, 5.6)].

Cytochrome P450-3A4 Inhibitors Caution is advised when Midazolam Injection is administered concomitantly with drugs that are known to inhibit the P450-3A4 enzyme system (e.g., cimetidine, erythromycin, diltiazem, verapamil, ketoconazole, and itraconazole). These drug interactions may result in prolonged sedation caused by a decrease in plasma clearance of midazolam [see Clinical Pharmacology (12.3)]. Benzodiazepines and Opioids: Risk of respiratory depression is increased.

(7.1) Other CNS Depressants and Alcohol: Sedative effect of midazolam is increased. (7.2) Cytochrome P450-3A4 Inhibitors: May result in prolonged sedation due to decreased plasma clearance of midazolam. (7.3)

👥 Use in Specific Populations ~3 min read ▾

Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antiepileptic drugs (AEDs), such as Midazolam Injection, during pregnancy. Healthcare providers are encouraged to recommend that pregnant women who are taking Midazolam Injection during pregnancy enroll in the North American Antiepileptic Drug (NAAED) pregnancy registry by calling 1-888-233-2334 or visiting http://www.aedpregnancyregistry.org/. Risk Summary Infants born to mothers using benzodiazepines late in pregnancy have been reported to experience symptoms of sedation and/or neonatal withdrawal [see Warnings and Precautions (5.9) and Clinical Considerations].

Available data from published observational studies of pregnant women exposed to benzodiazepines do not report a clear association with benzodiazepines and major birth defects (see Data). Administration of midazolam to rats and rabbits during the period of organogenesis or to rats during late pregnancy and throughout lactation at doses greater than those used clinically did not result in adverse effects on development (see Animal Data). Data for other benzodiazepines suggest the possibility of increased neuronal cell death and long-term effects on neurobehavioral and immunological function based on findings in animals following prenatal or early postnatal exposure at clinically relevant doses.

The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defects, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Clinical Considerations Fetal/Neonatal Adverse Reactions Benzodiazepines cross the placenta and may produce respiratory depression, hypotonia, and sedation in neonates. Monitor neonates exposed to Midazolam Injection during pregnancy or labor for signs of sedation, respiratory depression, hypotonia, and feeding problems. Monitor neonates exposed to Midazolam Injection during pregnancy for signs of withdrawal.

Manage these neonates accordingly [see Warnings and Precautions (5.9)]. Data Human Data Published data from observational studies on the use of benzodiazepines during pregnancy do not report a clear association with benzodiazepines and major birth defects. Although early studies reported an increased risk of congenital malformations with diazepam and chlordiazepoxide, there was no consistent pattern noted.

In addition, the majority of more recent case-control and cohort studies of benzodiazepine use during pregnancy, which were adjusted for confounding exposures to alcohol, tobacco and other medications, have not confirmed these findings. Animal Data When midazolam (0, 0.2, 1, or 4 mg/kg/day) was administered intravenously to pregnant rats during the period of organogenesis, no adverse effects on embryofetal development were observed. The highest dose tested, which was associated with minimal evidence of maternal toxicity, is approximately 4 times the recommended human dose (RHD) of 10 mg based on body surface area (mg/m 2 ).

When midazolam (0, 0.2, 0.6, and 2 mg/kg/day) was administered intravenously to rabbits during the period of organogenesis, no adverse effects on embryofetal development were reported. The high dose, which was not associated with evidence of maternal toxicity, is approximately 4 times the RHD on a mg/m 2 basis. When midazolam (0, 0.2, 1, or 4 mg/kg/day) was administered intravenously to female rats during late gestation and throughout lactation, no clear adverse effects were noted in the offspring.

The high dose, which was not associated with evidence of maternal toxicity, is approximately 4 times the RHD on a mg/m 2 basis. In published animal studies, administration of benzodiazepines or other drugs that enhance GABAergic inhibition to neonatal rats has been r… [Excerpted — this section continues on DailyMed.]

🆘 Overdosage ~1 min read ▾

Overdosage of benzodiazepines is characterized by central nervous system depression ranging from drowsiness to coma. In mild to moderate cases, symptoms can include drowsiness, confusion, dysarthria, lethargy, hypnotic state, diminished reflexes, ataxia, and hypotonia. Rarely, paradoxical or disinhibitory reactions (including agitation, irritability, impulsivity, violent behavior, confusion, restlessness, excitement, and talkativeness) may occur.

In severe overdosage cases, patients may develop respiratory depression and coma. Overdosage of benzodiazepines in combination with other CNS depressants (including alcohol and opioids) may be fatal [see Warnings and Precautions (5.2)]. Markedly abnormal (lowered or elevated) blood pressure, heart rate, or respiratory rate raise the concern that additional drugs and/or alcohol are involved in the overdosage.

In managing benzodiazepine overdosage, employ general supportive measures, including intravenous fluids and airway maintenance. Flumazenil, a specific benzodiazepine receptor antagonist indicated for the complete or partial reversal of the sedative effects of benzodiazepines in the management of benzodiazepine overdosage, can lead to withdrawal and adverse reactions, including seizures, particularly in the context of mixed overdosage with drugs that increase seizure risk (e.g., tricyclic and tetracyclic antidepressants) and in patients with long-term benzodiazepine use and physical dependency.

The risk of withdrawal seizures with flumazenil use may be increased in patients with epilepsy. Flumazenil is contraindicated in patients who have received a benzodiazepine for control of a potentially life-threatening condition (e.g., status epilepticus). If the decision is made to use flumazenil, it should be used as an adjunct to, not as a substitute for, supportive management of benzodiazepine overdosage.

See the flumazenil injection Prescribing Information. Consider contacting a poison center (1-800-221-2222) or a medical toxicologist for additional overdosage management recommendations.

🧬 Clinical Pharmacology ~3 min read ▾

Mechanism of Action The exact mechanism of action for midazolam in the treatment of status epilepticus is not fully understood, but is thought to involve potentiation of GABAergic neurotransmission resulting from binding at the benzodiazepine site of the GABAA receptor. Pharmacodynamics The effects of midazolam on the CNS are dependent on the dose administered, the route of administration, and the presence or absence of other medications. Pharmacokinetics The pharmacokinetics of midazolam were evaluated in a single dose-escalation trial in healthy subjects; following IM injection of midazolam at doses ranging from fixed total amounts of 5 mg to 30 mg (one half to three times the recommended dose) or body weight based dose of 0.10 mg/kg to 0.49 mg/kg, the overall median time to maximum plasma concentration (Tmax) was observed at approximately 0.5 hours after administration.

The rate and extent of systemic exposure, as assessed by maximum plasma concentration (Cmax) and area under the plasma drug concentration-time curve from time 0 to infinity (AUC0-∞), tended to increase proportionally with increasing dose from 5 mg to 30 mg. Absorption Following IM administration of a single 10 mg midazolam dose to healthy subjects via this autoinjector, midazolam was absorbed with median Tmax (range) of 0.5 (0.17 to 1.03) hours; midazolam mean (±SD) Cmax and AUC 0-∞ were 127 (±47.3) ng/mL and 454 (±134) ng∙hr/mL, respectively.

Distribution The mean (±SD) apparent volume of distribution (Vz/F) of midazolam following a single IM dose of 10 mg midazolam via this autoinjector was 169 (±61.7) L in healthy subjects. In humans, midazolam has been shown to cross the placenta and enter into fetal circulation, and has been detected in human milk and CSF [see Use in Specific Populations (8.1, 8.2)]. In adults, midazolam is approximately 97% bound to plasma protein, principally albumin.

The 1-hydroxy metabolite is approximately 89% bound to plasma protein Elimination Elimination of the parent drug takes place via hepatic metabolism of midazolam to hydroxylated metabolites that are conjugated and excreted in the urine. Metabolism In vitro studies with human liver microsomes indicate that the biotransformation of midazolam is mediated by the cytochrome P450-3A4 (CYP3A4). This enzyme is present in gastrointestinal tract mucosa, as well as in the liver.

The 1-hydroxy-midazolam (also termed alpha-hydroxymidazolam) metabolite comprises 60% to 70% of the biotransformation products of midazolam, while 4-hydroxy-midazolam constitutes 5% or less. Small amounts of a dihydroxy derivative have also been detected, but not quantified. The principal urinary excretion products are glucuronide conjugates of the hydroxylated derivatives.

Studies of the intravenous administration of 1-hydroxy-midazolam in humans suggest that 1-hydroxymidazolam is at least as potent as the parent compound, and may contribute to the net pharmacologic activity of midazolam. In vitro studies have demonstrated that the affinities of 1- and 4-hydroxy-midazolam for the benzodiazepine receptor are approximately 20% and 7%, respectively, relative to midazolam. Excretion Following IM administration of 10 mg midazolam via this autoinjector, mean (±SD) terminal elimination halflife was 5.16 (±1.77) hours and mean (±SD) apparent total body clearance (CL/F) of midazolam was and 23.8 (±6.77) L/hr.

The principal urinary excretion product is 1-hydroxy-midazolam in the form of a glucuronide conjugate; smaller amounts of the glucuronide conjugates of 4-hydroxy- and dihydroxy-midazolam are detected as well. The amount of midazolam excreted unchanged in the urine after a single IV dose is less than 0.5%. Following a single IV infusion in 5 healthy volunteers, 45% to 57% of the dose was excreted in the urine as the 1-hydroxymethyl midazolam conjugate.

Specific Populations Changes in the pharmacokinetic profile of midazolam due to drug interactions, physiological variables, etc., may result in changes in the pla… [Excerpted — this section continues on DailyMed.]

🔬 Clinical Studies ~1 min read ▾

The effectiveness of Midazolam Injection administered via this autoinjector for the treatment of status epilepticus in adults is based upon an adequate and well-controlled study of a different midazolam injection, which is described below, and a bioavailability study comparing intramuscular administration of 10 mg midazolam using this autoinjector versus midazolam vial in healthy adults. The safety and effectiveness of midazolam injection for the treatment of status epilepticus was established in a multi-center, randomized, double-blind (double-dummy), active-control trial comparing midazolam administered intramuscularly (IM) via a different autoinjector to lorazepam administered intravenously (IV).

Patients meeting the diagnosis of status epilepticus, with continuing convulsive seizure activity after the arrival of paramedics, were eligible for enrollment. The ITT population consisted of 893 patients who were randomized to receive either IM midazolam (n=448) or IV lorazepam (n=445). Following randomization, each patient received study treatments administered by a healthcare professional (e.g., paramedic) prior to arrival at a hospital.

According to the double-dummy design, adult patients received 10 mg IM midazolam followed by IV placebo or received IM placebo followed by 4 mg IV lorazepam. The primary efficacy endpoint was the termination of convulsive seizure activity (without the need for rescue medication) prior to arrival at the emergency department (ED) as determined by the ED attending physician. A statistically significantly higher percentage of midazolam-treated patients met the primary efficacy endpoint, as shown in Table 2.

🔒 Drug Abuse and Dependence ~3 min read ▾

Controlled Substance Midazolam Injection contains midazolam, a Schedule IV controlled substance. Abuse Midazolam is a benzodiazepine and a CNS depressant with a potential for abuse and addiction. Abuse is the intentional, non-therapeutic use of a drug, even once, for its desirable psychological or physiological effects.

Misuse is the intentional use, for therapeutic purposes, of a drug by an individual in a way other than prescribed by a health care provider or for whom it was not prescribed. Drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that may include a strong desire to take the drug, difficulties in controlling drug use (e.g., continuing drug use despite harmful consequences, giving a higher priority to drug use than other activities and obligations), and possible tolerance or physical dependence.

Even taking benzodiazepines as prescribed may put patients at risk for abuse and misuse of their medication. Abuse and misuse of benzodiazepines may lead to addiction. Abuse and misuse of benzodiazepines often (but not always) involve the use of doses greater than the maximum recommended dosage and commonly involve concomitant use of other medications, alcohol, and/or illicit substances, which is associated with an increased frequency of serious adverse outcomes, including respiratory depression, overdose, or death.

Benzodiazepines are often sought by individuals who abuse drugs and other substances, and by individuals with addictive disorders [see Warnings and Precautions (5.2)].The following adverse reactions have occurred with benzodiazepine abuse and/or misuse: abdominal pain, amnesia, anorexia, anxiety, aggression, ataxia, blurred vision, confusion, depression, disinhibition, disorientation, dizziness, euphoria, impaired concentration and memory, indigestion, irritability, muscle pain, slurred speech, tremors, and vertigo.

The following severe adverse reactions have occurred with benzodiazepine abuse and/or misuse: delirium, paranoia, suicidal ideation and behavior, seizures, coma, breathing difficulty, and death. Death is more often associated with polysubstance use (especially benzodiazepines with other CNS depressants such as opioids and alcohol). Midazolam was actively self-administered in primate models used to assess the positive reinforcing effects of psychoactive drugs.

Midazolam produced physical dependence of a mild to moderate intensity in cynomolgus monkeys after 5 to 10 weeks of administration. Available data concerning the drug abuse and dependence potential of midazolam suggest that its abuse potential is at least equivalent to that of diazepam. Dependence Physical Dependence After Use of Midazolam Injection More Frequently Than Recommended Midazolam Injection may produce physical dependence if used more frequently than recommended.

Physical dependence is a state that develops as a result of physiological adaptation in response to repeated drug use, manifested by withdrawal signs and symptoms after abrupt discontinuation or a significant dose reduction of a drug. Although Midazolam Injection is indicated only for intermittent use [see Indications and Usage (1) and Dosage and Administration (2)], if used more frequently than recommended, abrupt discontinuation or rapid dosage reduction or administration of flumazenil, a benzodiazepine antagonist, may precipitate acute withdrawal reactions, including seizures, which can be life-threatening.

Patients at an increased risk of withdrawal adverse reactions after benzodiazepine discontinuation or rapid dosage reduction include those who take higher dosages (i.e., higher and/or more frequent doses) and those who have had longer durations of use [see Warnings and Precautions (5.3)]. For patients using Midazolam Injection more frequently than recommended, to reduce the risk of withdrawal reactions, use a gradual taper to discontinue Midazolam Injection [see Warnings and Precautions (5.3)]. Acute Withdrawal Signs and Symptoms Acute with… [Excerpted — this section continues on DailyMed.]

🧪 Nonclinical Toxicology 212 words ▾

Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis Midazolam maleate was administered in the diet to mice and rats for 2 years at doses of 0, 1, 9, or 80 mg/kg/day. In female mice in the highest dose group there was a marked increase in the incidence of hepatic tumors. In highdose male rats there was a small but statistically significant increase in benign thyroid follicular cell tumors.

The highest dose not associated with increased tumor incidences in mice and rats (9 mg/kg/day) is approximately 4 and 9 times, respectively, the recommended human dose (RHD) of 10 mg based on body surface area (mg/m2). The pathogenesis of induction of these tumors is not known. These tumors were found after chronic administration, whereas human use will ordinarily be of single or several doses.

Mutagenesis Midazolam was negative for genotoxicity in in vitro (Ames, mammalian cell clastogenicity) and in vivo (mouse bone marrow micronucleus) assays. Impairment of Fertility When midazolam (0, 1, 4, or 16 mg/kg) was orally administered to male and female rats prior to and during mating and continuing in females throughout gestation and lactation, no adverse effects on male or female fertility were noted. Midazolam plasma exposures (AUC) at the highest dose tested were approximately 6 times that in humans at the RHD.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The form printed on the packaging and shown on DailyMed is the one the FDA registered. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero and the dashes are dropped. The Identity section at the top of this page lists each form of this code.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Rafa Laboratories, Ltd.. Listing status can change — the directory data on this page refreshes weekly.
