Visual and auditory hallucinations have also been reported.

Other complex behaviors e. Amnesia, anxiety and other neuro-psychiatric symptoms may also occur. The emergence of any new behavioral sign or symptom of concern requires careful and immediate evaluation. In primarily depressed patients treated with sedative-hypnotics, worsening of depression, and suicidal thoughts and actions including completed suicides , have been reported. Suicidal tendencies may be present in such patients and protective measures may be required.

Intentional overdosage is more common in this group of patients; therefore, the lowest number of tablets that is feasible should be prescribed for the patient at any one time. Since sedative-hypnotics have the capacity to depress respiratory drive, precautions should be taken if Intermezzo is prescribed to patients with compromised respiratory function. Post-marketing reports of respiratory insufficiency in patients receiving 10 mg of zolpidem tartrate, most of whom had pre-existing respiratory impairment, have been reported.

The risks of respiratory depression should be considered prior to prescribing Intermezzo in patients with respiratory impairment including sleep apnea and myasthenia gravis. There have been reports of withdrawal signs and symptoms following the rapid dose decrease or abrupt discontinuation of zolpidem. Monitor patients for tolerance, abuse, and dependence [see Drug Abuse and Dependence ].

Inform patients and their families about the benefits and risks of treatment with Intermezzo.

In mice, these doses are approximately 7, 30, and times, respectively, the recommended human dose RHD of 3. No evidence of carcinogenic potential was observed in mice. In rats, renal tumors lipoma , liposarcoma were seen at the mid-and high doses. Zolpidem was negative in in vitro bacterial reverse mutation, mouse lymphoma, and chromosomal aberration and in vivo mouse micronucleus genetic toxicology assays.

There was no impairment of fertility at any dose tested. There are no adequate and well-controlled studies of zolpidem 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. Intermezzo 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 at doses greater than the recommended human dose RHD of 3.

For a pool of U. The dose of Intermezzo in elderly patients is 1. Women cleared zolpidem tartrate from the body after sublingual administration of a 3. Given the higher blood levels of zolpidem tartrate in women compared to men at a given dose, the recommended dose of Intermezzo for women is 1. 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 flumazenil 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 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 management of all overdosage, the possibility of multiple drug ingestion should be considered. The healthcare provider may wish to consider contacting a poison control center for up-to-date information on the management of hypnotic drug overdosage. Intermezzo is contraindicated in patients with known hypersensitivity to zolpidem. 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.

This selective binding of zolpidem on the BZ1 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 at hypnotic doses. Intermezzo disintegrates in the sublingual cavity after administration. On average, Intermezzo is rapidly absorbed in both genders, with a mean Tmax across studies of about 35 minutes to about 75 minutes.

In healthy normal volunteers age 21 to 45 years dosed with 3. In women, the average Cmax and AUC of the 1. Based on data obtained with oral zolpidem, zolpidem tartrate is converted to inactive metabolites that are eliminated primarily by renal excretion. The elimination half-life of a single dose of a 3. The recommended dose for Intermezzo is 1. A pharmacokinetic study of 1. The Cmax and AUC of 1. The elimination half-life remained unchanged.

The pharmacokinetics of oral zolpidem tartrate in eight patients with chronic hepatic insufficiency were compared to results in subjects with normal hepatic function. Tmax did not change. The mean half-life in cirrhotic patients of 9. No statistically significant differences were observed for Cmax, Tmax, half-life, and AUC between the first and last day of drug administration when baseline concentration adjustments were made.

Zolpidem was not hemodialyzable. No accumulation of unchanged drug appeared after 14 or 21 days. Zolpidem pharmacokinetics were not significantly different in renallyimpaired patients.

There was no evidence of an additive effect in psychomotor performance. The effect of inhibitors of other P enzymes on the pharmacokinetics of zolpidem is unknown.

There were no pharmacodynamic effects of zolpidem detected on subjective drowsiness, postural sway, or psychomotor performance. Zolpidem tartrate had no effect on digoxin pharmacokinetics and did not affect prothrombin time when given with warfarin in healthy subjects. Intermezzo was evaluated in two randomized, double-blind, placebo-controlled studies Studies 1 and 2 in patients with insomnia characterized by difficulty returning to sleep after a middle-ofthe-night MOTN awakening.

The primary outcome measure was latency to persistent sleep LPS. The effect on sleep latency was similar for females receiving 1. Patients took study drug 3. Subjective patient-estimated time to fall back to sleep after middle-of-the-night awakening was significantly shorter for Intermezzo 3. A randomized, double-blind, placebo-controlled, active-control, single-center, four-period, crossover study in 40 healthy subjects was conducted to evaluate the effects of middle-of-thenight administration of Intermezzo on next-morning driving performance.

The four randomized treatments included Intermezzo 3. The primary outcome measure was the change in the standard deviation of lateral position SDLP , a measure of driving impairment. The results were analyzed using a symmetry analysis, which determined the proportion of subjects whose change from their own SDLP in the placebo condition was statistically significantly above a threshold thought to reflect clinically meaningful driving impairment.

When driving began 3 hours after taking Intermezzo, testing had to be terminated for one subject a year old woman due to somnolence. Overall, the symmetry analysis showed a statistically significant impairing effect at 3 hours. When driving began 4 hours after taking Intermezzo, statistically significant impairment was not found, but numerically Intermezzo was worse than placebo.

Zolpidem blood levels were not measured in the driving study, and the study was not designed to correlate specific blood level with degree of impairment. However, the estimated blood level of zolpidem in patients whose SDLP worsened according to the symmetry analysis is considered to present a risk for driving impairment. In some women, the 3. Therefore, the recommended dose for women is 1. A small negative effect on SDLP may remain in some patients 4 hours after the 1.

In studies performed with other zolpidem formulations 5 mg to 10 mg oral zolpidem tartrate given at bedtime, there was no objective polysomnographic evidence of rebound insomnia at recommended doses seen in studies evaluating sleep on the nights following discontinuation. There was subjective evidence of impaired sleep in the elderly on the first post-treatment night at doses above the recommended elderly dose of 5 mg oral zolpidem tartrate. Controlled studies in adults utilizing objective measures of memory yielded no consistent evidence of next-day memory impairment following the administration at bedtime of 5 mg to 10 mg oral zolpidem tartrate.

However, in one study involving zolpidem tartrate doses of 10 mg and 20 mg, there was a significant decrease in next-morning recall of information presented to subjects during peak drug effect 90 minutes post-dose , i. There was also subjective evidence from adverse event data for anterograde amnesia occurring in association with the administration of oral zolpidem tartrate, predominantly at doses above 10 mg. Read the Medication Guide that comes with Intermezzo before you start taking it and each time you get a refill.
