⏱️ Dosage and Administration ▾
2DOSAGE AND ADMINISTRATION • Use the lowest dose effective for the patient ( 2.1 ) • Recommended initial dose is 6.25 mg for women, and 6.25 or 12.5 mg for men, immediately before bedtime with at least 7 to 8 hours remaining before the planned time of awakening ( 2.1 ) • Geriatric patients and patients with hepatic impairment: Recommended dose is 6.25 mg for men and women ( 2.2 ) • Lower doses of CNS depressants may be necessary when taken concomitantly with zolpidem tartrate extended-release tablets, USP ( 2.3 ) • Tablets to be swallowed whole, not to be crushed, divided or chewed ( 2.4 ) • The effect of zolpidem tartrate extended-release tablets, USP may be slowed if taken with or immediately after a meal ( 2.4 ) 2.1Dosage in Adults Use the lowest effective dose for the patient.
The recommended initial dose is 6.25 mg for women and either 6.25 or 12.5 mg for men, taken only once per night immediately before bedtime with at least 7 to 8 hours remaining before the planned time of awakening. If the 6.25 mg dose is not effective, the dose can be increased to 12.5 mg. In some patients, the higher morning blood levels following use of the 12.5 mg dose increase the risk of next day impairment of driving and other activities that require full alertness [see WARNINGS AND PRECAUTIONS (5.1) ].
The total dose of zolpidem tartrate extended-release tablet, USP should not exceed 12.5 mg once daily immediately before bedtime. The recommended initial doses for women and men are different because zolpidem clearance is lower in women.
2.2Special Populations Elderly or debilitated patients may be especially sensitive to the effects of zolpidem tartrate. Patients with hepatic insufficiency do not clear the drug as rapidly as normal subjects. The recommended dose of zolpidem tartrate extended-release tablets in both of these patient populations is 6.25 mg once daily immediately before bedtime [see WARNINGS AND PRECAUTIONS (5.1) ; USE IN SPECIFIC POPULATIONS (8.5) ].
2.3Use with CNS Depressants Dosage adjustment may be necessary when zolpidem tartrate extended-release tablets are combined with other CNS depressant drugs because of the potentially additive effects [see WARNINGS AND PRECAUTIONS (5.1) ].
2.4Administration Zolpidem tartrate extended-release tablets should be swallowed whole, and not be divided, crushed, or chewed. The effect of zolpidem tartrate extended-release tablets may be slowed by ingestion with or immediately after a meal.

⛔ Contraindications ▾
4 CONTRAINDICATIONS Zolpidem tartrate extended-release tablets are contraindicated in patients with known hypersensitivity to zolpidem. Observed reactions include anaphylaxis and angioedema [see WARNINGS AND PRECAUTIONS (5.3) ] . Known hypersensitivity to zolpidem ( 4 )
⚠️ Warnings and Cautions ▾
5WARNINGS AND PRECAUTIONS • CNS depressant effects: Impaired alertness and motor coordination, including risk of morning impairment. Caution patients against driving and other activities requiring complete mental alertness the morning after use. ( 5.1 ) • Need to evaluate for co-morbid diagnoses: Revaluate if insomnia persists after 7 to 10 days of use ( 5.2 ) • Severe anaphylactic/anaphylactoid reactions: Angioedema and anaphylaxis have been reported.
Do not rechallenge if such reactions occur. ( 5.3 ) • "Sleep-driving" and other complex behaviors while not fully awake. Risk increases with dose and use with other CNS depressants and alcohol.
Immediately evaluate any new onset behavioral changes. ( 5.4 ) • Depression: Worsening of depression or, suicidal thinking may occur. Prescribe the least amount of tablets feasible to avoid intentional overdose.
( 5.5 ) • Respiratory Depression: Consider this risk before prescribing in patients with compromised respiratory function ( 5.6 ) • Withdrawal effects: Symptoms may occur with rapid dose reduction or discontinuation ( 5.7 , 9.3 )
5.1CNS Depressant Effects and Next-Day Impairment Zolpidem tartrate extended-release are a central nervous system (CNS) depressant and can impair daytime function in some patients even when used as prescribed. Prescribers should monitor for excess depressant effects, but impairment can occur in the absence of subjective symptoms, and may not be reliably detected by ordinary clinical exam (i.e. less than formal psychomotor testing). While pharmacodynamic tolerance or adaptation to some adverse depressant effects of zolpidem tartrate extended-release may develop, patients using zolpidem tartrate extended-release should be cautioned against driving or engaging in other hazardous activities or activities requiring complete mental alertness the day after use.
Additive effects occur with concomitant use of other CNS depressants (e.g. benzodiazepines, opioids, tricyclic antidepressants, alcohol), including daytime use. Downward dose adjustment of zolpidem tartrate extended-release tablet are and concomitant CNS depressants should be considered [see DOSAGE AND ADMINISTRATION (2.3) ]. The use of zolpidem tartrate extended-release with other sedative-hypnotics (including other zolpidem products) at bedtime or the middle of the night is not recommended.
The risk of next-day psychomotor impairment is increased if zolpidem tartrate extended-release is taken with less than a full night of sleep remaining (7 to 8 hours); if higher than the recommended dose is taken; if co-administered with other CNS depressants; or co-administered with other drugs that increase the blood levels of zolpidem [see DOSAGE AND ADMINISTRATION (2) and CLINICAL STUDIES (14.2) ].
5.2Need to Evaluate for Co-morbid Diagnoses Because sleep disturbances may be the presenting manifestation of a physical and/or psychiatric disorder, symptomatic treatment of insomnia should be initiated only after a careful evaluation of the patient. The failure of insomnia to remit after 7 to 10 days of treatment may indicate the presence of a primary psychiatric and/or medical illness that should be evaluated. Worsening of insomnia or the emergence of new thinking or behavior abnormalities may be the consequence of an unrecognized psychiatric or physical disorder.
Such findings have emerged during the course of treatment with sedative/hypnotic drugs, including zolpidem.
5.3Severe Anaphylactic and Anaphylactoid Reactions Cases of angioedema involving the tongue, glottis or larynx have been reported in patients after taking the first or subsequent doses of sedative-hypnotics, including zolpidem. Some patients have had additional symptoms such as dyspnea, throat closing or nausea and vomiting that suggest anaphylaxis. Some patients have required medical therapy in the emergency department.
If angioedema involves the throat, glottis or larynx, airway obstruction may occur and be fatal. Patients who develop angioedema…
🤒 Adverse Reactions ▾
6ADVERSE REACTIONS The following serious adverse reactions are discussed in greater detail in other sections of the labeling: • CNS-depressant effects and next-day impairment [see WARNINGS AND PRECAUTIONS (5.1) ] • Serious anaphylactic and anaphylactoid reactions [see WARNINGS AND PRECAUTIONS (5.3) ] • Abnormal thinking and behavior changes, and complex behaviors [see WARNINGS AND PRECAUTIONS (5.4) ] • Withdrawal effects [see WARNINGS AND PRECAUTIONS (5.7) ] Most commonly observed adverse reactions (> 10% in either elderly or adult patients) are: headache, next-day somnolence and dizziness ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Sandoz Inc. at 1-800-525-8747 or FDA at 1-800-FDA-1088 or http://www.fda.gov/medwatch.
6.1Clinical Trials Experience Associated with discontinuation of treatment: In 3-week clinical trials in adults and elderly patients (> 65 years), 3.5% (7/201) patients receiving zolpidem tartrate extended-release 6.25 or 12.5 mg discontinued treatment due to an adverse reaction as compared to 0.9% (2/216) of patients on placebo. The reaction most commonly associated with discontinuation in patients treated with zolpidem tartrate extended-release was somnolence (1%). In a 6-month study in adult patients (18 to 64 years of age), 8.5% (57/669) of patients receiving zolpidem tartrate extended-release 12.5 mg as compared to 4.6% on placebo (16/349) discontinued treatment due to an adverse reaction.
Reactions most commonly associated with discontinuation of zolpidem tartrate extended-release included anxiety (anxiety, restlessness or agitation) reported in 1.5% (10/669) of patients as compared to 0.3% (1/349) of patients on placebo, and depression (depression, major depression or depressed mood) reported in 1.5% (10/669) of patients as compared to 0.3% (1/349) of patients on placebo. Data from a clinical study in which selective serotonin reuptake inhibitor- (SSRI-) treated patients were given zolpidem revealed that four of the seven discontinuations during double-blind treatment with zolpidem (n=95) were associated with impaired concentration, continuing or aggravated depression, and manic reaction; one patient treated with placebo (n =97) was discontinued after an attempted suicide.
Most commonly observed adverse reactions in controlled trials: During treatment with zolpidem tartrate extended-release in adults and elderly at daily doses of 12.5 mg and 6.25 mg, respectively, each for three weeks, the most commonly observed adverse reactions associated with the use of zolpidem tartrate extended-release were headache, next-day somnolence, and dizziness. In the 6-month trial evaluating zolpidem tartrate extended-release 12.5 mg, the adverse reaction profile was consistent with that reported in short-term trials, except for a higher incidence of anxiety (6.3% for zolpidem tartrate extended-release versus 2.6% for placebo).
Adverse reactions observed at an incidence of ≥1% in controlled trials: The following tables enumerate treatment-emergent adverse reaction frequencies that were observed at an incidence equal to 1% or greater among patients with insomnia who received zolpidem tartrate extended-release in placebo-controlled trials. Events reported by investigators were classified utilizing the MedDRA dictionary for the purpose of establishing event frequencies. The prescriber should be aware that these figures cannot be used to predict the incidence of side effects in the course of usual medical practice, in which patient characteristics and other factors differ from those that prevailed in these clinical trials.
Similarly, the cited frequencies cannot be compared with figures obtained from other clinical investigators involving related drug products and uses, since each group of drug trials is conducted under a different set of conditions. However, the cited figures provide the physician with a basis for estimating the relative contribution of drug and nondrug factors to the incidence of side effects in the…
🔄 Drug Interactions ▾
7DRUG INTERACTIONS • CNS depressants, including alcohol: Possible adverse additive CNS-depressant effects ( 5.1 , 7.1 ) • Imipramine: Decreased alertness observed ( 7.1 ) • Chlorpromazine: Impaired alertness and psychomotor performance observed ( 7.1 ) • Rifampin: Combination use may decrease effect ( 7.2 ) • Ketoconazole: Combination use may increase effect ( 7.2 )
7.1CNS-Active Drugs Co-administration of zolpidem with other CNS depressants increases the risk of CNS depression [see WARNINGS AND PRECAUTIONS (5.1) ]. Zolpidem tartrate was evaluated in healthy volunteers in single-dose interaction studies for several CNS drugs. Imipramine, Chlorpromazine Imipramine in combination with zolpidem produced no pharmacokinetic interaction other than a 20% decrease in peak levels of imipramine, but there was an additive effect of decreased alertness.
Similarly, chlorpromazine in combination with zolpidem produced no pharmacokinetic interaction, but there was an additive effect of decreased alertness and psychomotor performance [see CLINICAL PHARMACOLOGY (12.3) ]. Haloperidol A study involving haloperidol and zolpidem revealed no effect of haloperidol on the pharmacokinetics or pharmacodynamics of zolpidem. The lack of a drug interaction following single-dose administration does not predict the absence of an effect following chronic administration [see CLINICAL PHARMACOLOGY (12.3) ].
Alcohol An additive adverse effect on psychomotor performance between alcohol and oral zolpidem was demonstrated [see WARNINGS AND PRECAUTIONS (5.1) ]. Sertraline Concomitant administration of zolpidem and sertraline increases exposure to zolpidem [see CLINICAL PHARMACOLOGY (12.3) ]. Fluoxetine After multiple doses of zolpidem tartrate and fluoxetine an increase in the zolpidem half-life (17%) was observed.
There was no evidence of an additive effect in psychomotor performance [see CLINICAL PHARMACOLOGY (12.3) ].
7.2Drugs that Affect Drug Metabolism via Cytochrome P450 Some compounds known to inhibit CYP3A may increase exposure to zolpidem. The effect of drugs on other P450 enzymes on the exposure to zolpidem is not known. Rifampin Rifampin, a CYP3A4 inducer, significantly reduced the exposure to and the pharmacodynamic effects of zolpidem.
Use of Rifampin in combination with zolpidem may decrease the efficacy of zolpidem. Ketoconazole Ketoconazole, a potent CYP3A4 inhibitor, increased the pharmacodynamic effects of zolpidem. Consideration should be given to using a lower dose of zolpidem when ketoconazole and zolpidem are given together.
👥 Use in Specific Populations ▾
8USE IN SPECIFIC POPULATIONS • Pregnancy: Based on animal data may cause fetal harm ( 8.1 ) • Pediatric use: Safety and effectiveness not established. Hallucinations (incidence rate 7%) and other psychiatric and/or nervous system adverse reactions were observed frequently in a study of pediatric patients with Attention-Deficit/Hyperactivity Disorder ( 5.4 , 8.4 )
8.1Pregnancy Pregnancy Category C There are no adequate and well-controlled studies of zolpidem tartrate extended-release in pregnant women. Studies in children to assess the effects of prenatal exposure to zolpidem have not been conducted; however, cases of severe neonatal respiratory depression have been reported when zolpidem was used at the end of pregnancy, especially when taken with other CNS depressants. Children born to mothers taking sedative-hypnotic drugs may be at risk for withdrawal symptoms during the postnatal period.
Neonatal flaccidity has also been reported in infants born to mothers who received sedative-hypnotic drugs during pregnancy. Zolpidem tartrate extended-release should be used during pregnancy only if the potential benefit outweighs the potential risk to the fetus. Administration of zolpidem to pregnant rats and rabbits resulted in adverse effects on offspring development at doses greater than the zolpidem tartrate extended-release maximum recommended human dose (MRHD) of 12.5 mg/day (approximately 10 mg/day zolpidem base); however, teratogenicity was not observed.
When zolpidem was administered at oral doses of 4, 20, and 100 mg base/kg/day to pregnant rats during the period of organogenesis, dose-related decreases in fetal skull ossification occurred at all but the lowest dose, which is approximately 4 times the MRHD on a mg/m 2 basis. In rabbits treated during organogenesis with zolpidem at oral doses of 1, 4, and 16 mg base/kg/day, increased embryo-fetal death and incomplete fetal skeletal ossification occurred at the highest dose. The no-effect dose for embryo-fetal toxicity in rabbits is approximately 8 times the MRHD on a mg/m 2 basis.
Administration of zolpidem to rats at oral doses of 4, 20, and 100 mg base/kg/day during the latter part of pregnancy and throughout lactation produced decreased offspring growth and survival at all but the lowest dose, which is approximately 4 times the MRHD on a mg/m 2 basis.
8.2Labor and Delivery Zolpidem tartrate extended-release tablet has no established use in labor and delivery [see PREGNANCY (8.1) ].
8.3Nursing Mothers Zolpidem is excreted in human milk. Caution should be exercised when zolpidem tartrate extended-release tablet is administered to a nursing woman.
8.4Pediatric Use Zolpidem tartrate extended-release is not recommended for use in children. Safety and effectiveness of zolpidem in pediatric patients below the age of 18 years have not been established. In an 8-week study in pediatric patients (aged 6 to 17 years) with insomnia associated with attention-deficit/hyperactivity disorder (ADHD) an oral solution of zolpidem tartrate dosed at 0.25 mg/kg at bedtime did not decrease sleep latency compared to placebo..
Psychiatric and nervous system disorders comprised the most frequent (> 5%) treatment emergent adverse reactions observed with zolpidem versus placebo and included dizziness (23.5% vs. 1.5%), headache (12.5% vs. 9.2%), and hallucinations were reported in 7% of the pediatric patients who received zolpidem; none of the pediatric patients who received placebo reported hallucinations [see WARNINGS AND PRECAUTIONS (5.4) ].
Ten patients on zolpidem (7.4%) discontinued treatment due to an adverse reaction. FDA has not required pediatric studies of zolpidem tartrate extended-release tablets in the pediatric population based on these efficacy and safety findings.
8.5Geriatric Use A total of 99 elderly (≥ 65 years of age) received daily doses of 6.25 mg zolpidem tartrate extended-release in a 3-week placebo-controlled study. The adverse reaction profile of zolpidem tartrate extended-…

Psychiatric and nervous system disorders comprised the most frequent (> 5%) treatment emergent adverse reactions observed with zolpidem versus placebo and included dizziness (23.5% vs. 1.5%), headache (12.5% vs. 9.2%), and hallucinations were reported in 7% of the pediatric patients who received zolpidem; none of the pediatric patients who received placebo reported hallucinations [see WARNINGS AND PRECAUTIONS (5.4) ].
Ten patients on zolpidem (7.4%) discontinued treatment due to an adverse reaction. FDA has not required pediatric studies of zolpidem tartrate extended-release tablets in the pediatric population based on these efficacy and safety findings.
🧓 Geriatric Use ▾
8.5Geriatric Use A total of 99 elderly (≥ 65 years of age) received daily doses of 6.25 mg zolpidem tartrate extended-release in a 3-week placebo-controlled study. The adverse reaction profile of zolpidem tartrate extended-release 6.25 mg in this population was similar to that of zolpidem tartrate extended-release 12.5 mg in younger adults (≤ 64 years of age). Dizziness was reported in 8% of zolpidem tartrate extended-release-treated patients compared with 3% of those treated with placebo.
The dose of zolpidem tartrate extended-release in elderly patients is 6.25 mg to minimize adverse effects related to impaired motor and/or cognitive performance and unusual sensitivity to sedative/hypnotic drugs [see WARNINGS AND PRECAUTIONS (5.1) ] .
🆘 Overdosage ▾
10OVERDOSAGE
10.1Signs and Symptoms In postmarketing experience of overdose with zolpidem tartrate alone, or in combination with CNS-depressant agents, impairment of consciousness ranging from somnolence to coma, cardiovascular and/or respiratory compromise and fatal outcomes have been reported.
10.2Recommended Treatment General symptomatic and supportive measures should be used along with immediate gastric lavage where appropriate. Intravenous fluids should be administered as needed. Zolpidem's sedative hypnotic effect was shown to be reduced by flumazenil and therefore may be useful; however, flumazenil administration may contribute to the appearance of neurological symptoms (convulsions).
As in all cases of drug overdose, respiration, pulse, blood pressure, and other appropriate signs should be monitored and general supportive measures employed. Hypotension and CNS depression should be monitored and treated by appropriate medical intervention. Sedating drugs should be withheld following zolpidem overdosage, even if excitation occurs.
The value of dialysis in the treatment of overdosage has not been determined, although hemodialysis studies in patients with renal failure receiving therapeutic doses have demonstrated that zolpidem is not dialyzable. As with the management of all overdosage, the possibility of multiple drug ingestion should be considered. The physician may wish to consider contacting a poison control center for up-to-date information on the management of hypnotic drug product overdosage.
🧬 Clinical Pharmacology ▾
12CLINICAL PHARMACOLOGY
12.1Mechanism of Action Zolpidem, the active moiety of zolpidem tartrate, is a hypnotic agent with a chemical structure unrelated to benzodiazepines, barbiturates, or other drugs with known hypnotic properties. It interacts with a GABA-BZ receptor complex and shares some of the pharmacological properties of the benzodiazepines. In contrast to the benzodiazepines, which non-selectively bind to and activate all BZ receptor subtypes, zolpidem in vitro binds the BZ 1 receptor preferentially with a high affinity ratio of the α 1 /α 5 subunits.
This selective binding of zolpidem on the BZ 1 receptor is not absolute, but it may explain the relative absence of myorelaxant and anticonvulsant effects in animal studies as well as the preservation of deep sleep (stages 3 and 4) in human studies of zolpidem tartrate at hypnotic doses.
12.3Pharmacokinetics Zolpidem tartrate extended-release exhibits biphasic absorption characteristics, which results in rapid initial absorption from the gastrointestinal tract similar to zolpidem tartrate immediate-release, then provides extended plasma concentrations beyond three hours after administration. A study in 24 healthy male subjects was conducted to compare mean zolpidem plasma concentration-time profiles obtained after single oral administration of zolpidem tartrate extended-release 12.5 mg and of an immediate-release formulation of zolpidem tartrate (10 mg).
The terminal elimination half-life observed with zolpidem tartrate extended-release (12.5 mg) was similar to that obtained with immediate-release zolpidem tartrate (10 mg). The mean plasma concentration-time profiles are shown in Figure 1 . Figure 1: Mean plasma concentration-time profiles for zolpidem tartrate extended-release (12.5 mg) and immediate-release zolpidem tartrate (10 mg) Figure 1: Mean plasma concentration-time profiles for zolpidem tartrate extended-release (12.5 mg) and immediate-release zolpidem tartrate (10 mg) In adult and elderly patients treated with zolpidem tartrate extended-release, there was no evidence of accumulation after repeated once-daily dosing for up to two weeks.
Absorption: Following administration of zolpidem tartrate extended-release, administered as a single 12.5 mg dose in healthy male adult subjects, the mean peak concentration (C max ) of zolpidem was 134 ng/mL (range: 68.9 to 197 ng/ml) occurring at a median time (T max ) of 1.5 hours. The mean AUC of zolpidem was 740 ng∙hr/mL (range: 295 to 1359 ng∙hr/mL). A food-effect study in 45 healthy subjects compared the pharmacokinetics of zolpidem tartrate extended-release 12.5 mg when administered while fasting or within 30 minutes after a meal.
Results demonstrated that with food, mean AUC and C max were decreased by 23% and 30%, respectively, while median T max was increased from 2 hours to 4 hours. The half-life was not changed. These results suggest that, for faster sleep onset, zolpidem tartrate extended-release should not be administered with or immediately after a meal.
Distribution: Total protein binding was found to be 92.5 ± 0.1% and remained constant, independent of concentration between 40 and 790 ng/mL. Metabolism: Zolpidem is converted to inactive metabolites that are eliminated primarily by renal excretion. Elimination: When zolpidem tartrate extended-release was administered as a single 12.5 mg dose in healthy male adult subjects, the mean zolpidem elimination half-life was 2.8 hours (range: 1.62 to 4.05 hr).
Special Populations Elderly: In 24 elderly (≥ 65 years) healthy subjects administered a single 6.25 mg dose of zolpidem tartrate extended-release, the mean peak concentration (C max ) of zolpidem was 70.6 (range: 35 to 161) ng/mL occurring at a median time (T max ) of 2 hours. The mean AUC of zolpidem was 413 ng∙hr/mL (range: 124 to 1190 ng∙hr/mL) and the mean elimination half-life was 2.9 hours (range: 1.59 to 5.50 hours). Hepatic Impairment: Zolpidem tartrate extended-release was not studied in patients with…
