Ambien (Zolpidem Tartrate) User Reviews, Side Effects, Interactions

The table is limited to data from doses up to and including 10 mg, the highest dose recommended for use. The following table was derived from results of three placebo-controlled long-term efficacy trials involving AMBIEN (zolpidem tartrate). These trials involved patients with chronic insomnia who were treated for 28 to 35 nights with zolpidem at doses of 5, 10, or 15 mg. The table includes only adverse events occurring at an incidence of at least 1% for zolpidem patients.

Dosage adjustment may be necessary when AMBIEN is combined with other CNS depressant drugs because of the potentially additive effects.

Consideration should be given to using a lower dose of zolpidem when a potent CYP3A4 inhibitor and zolpidem are given together. Ketoconazole, a potent CYP3A4 inhibitor, increased the exposure to and pharmacodynamic effects of zolpidem.

The recommended initial doses for women and men are different because zolpidem clearance is lower in women.

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.

Reactions most commonly associated with discontinuation from U.S. Approximay 4% of 1,959 patients who received zolpidem at all doses (1 to 50 mg) in similar foreign trials discontinued treatment because of an adverse reaction.

The 5 mg tablet also contains FD&C Red No.

placebo-controlled trials. Events reported by investigators were classified utilizing a modified World Health Organization (WHO) dictionary of preferred terms for the purpose of establishing event frequencies. 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 population studied. The following tables enumerate treatment-emergent adverse reactions frequencies that were observed at an incidence equal to 1% or greater among patients with insomnia who received zolpidem tartrate and at a greater incidence than placebo in U.S. 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.

Rifampin, a CYP3A4 inducer, significantly reduced the exposure to and the pharmacodynamic effects of zolpidem. Use of CYP3A4 inducers in combination with zolpidem may decrease the efficacy of zolpidem.

Concomitant use of zolpidem with these drugs may increase drowsiness and psychomotor impairment, including impaired driving ability. Co-administration of zolpidem with other CNS depressants increases the risk of CNS depression. Zolpidem tartrate was evaluated in healthy volunteers in single-dose interaction studies for several CNS drugs.

The following adverse events which are considered to meet the DSM -III-R criteria for uncomplicated sedative/ hypnotic withdrawal were reported during U.S. Sedative /hypnotics have produced withdrawal signs and symptoms following abrupt discontinuation. These reported symptoms range from mild dysphoria and insomnia to a withdrawal syndrome that may include abdominal and muscle cramps, vomiting, sweating, tremors, and convulsions. clinical trials following placebo substitution occurring within 48 hours following last zolpidem treatment: fatigue, nausea, flushing, lightheadedness, uncontrolled crying, emesis, stomach cramps, panic attack, nervousness, and abdominal discomfort. Post-marketing reports of abuse, dependence and withdrawal have been received. These reported adverse events occurred at an incidence of 1% or less. However, available data cannot provide a reliable estimate of the incidence, if any, of dependence during treatment at recommended doses.

Treatment-emergent adverse events associated with clinical trial participation were recorded by clinical investigators using terminology of their own choosing. AMBIEN was administered to,660 subjects in clinical trials throughout the U.S., Canada, and Europe. To provide a meaningful estimate of the proportion of individuals experiencing treatment-emergent adverse events, similar types of untoward events were grouped into a smaller number of standardized event categories and classified utilizing a modified World Health Organization (WHO) dictionary of preferred terms.

In some patients, the higher morning blood levels following use of the 10 mg dose increase the risk of next day impairment of driving and other activities that require full alertness. Ambien should be taken as a single dose and should not be readministered during the same night. If the 5 mg dose is not effective, the dose can be increased to 10 mg. Use the lowest effective dose for the patient. The total dose of AMBIEN should not exceed 10 mg once daily immediay before bedtime. The recommended initial dose is 5 mg for women and either 5 or 10 mg for men, taken only once per night immediay before bedtime with at least 7–8 hours remaining before the planned time of awakening.

Patients with mild to moderate hepatic impairment do not clear the drug as rapidly as normal subjects. Avoid AMBIEN use in patients with severe hepatic impairment as it may contribute to encephalopathy [see WARNINGS AND PRECAUTIONS, Use In Specific Populations, CLINICAL PHARMACOLOGY ]. The recommended dose of AMBIEN in these patients is 5 mg once daily immediay before bedtime.

An additive adverse effect on psychomotor performance between alcohol and oral zolpidem was demonstrated.

Abuse is characterized by misuse of the drug for non-medical purposes, often in combination with other psychoactive substances. Addiction is a primary, chronic, neurobiological disease with genetic, psychosocial, and environmental factors influencing its development and manifestations. Abuse and addiction are separate and distinct from physical dependence and tolerance. Tolerance may occur to both desired and undesired effects of drugs and may develop at different rates for different effects. Tolerance is a state of adaptation in which exposure to a drug induces changes that result in a diminution of one or more of the drug effects over time. It is characterized by behaviors that include one or more of the following: impaired control over drug use, compulsive use, continued use despite harm, and craving. Drug addiction is a treatable disease, using a multidisciplinary approach, but relapse is common.

Rare: bilirubinemia, increased SGOT. Metabolic and nutritional:. Infrequent: abnormal hepatic function, increased SGPT.

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 following adverse reactions have been identified during post-approval use of AMBIEN.

AMBIEN 10 mg tablets are capsule-shaped, white, film coated, with AMB 10 debossed on one side and 5421 on the other and supplied as:

Central and peripheral nervous system:

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.

Tablets are not scored. AMBIEN is available in 5 mg and 10 mg strength tablets for oral administration.

Hematologic and lymphatic system:

AMBIEN has been shown to decrease sleep latency for up to 35 days in controlled clinical studies. AMBIEN (zolpidem tartrate) is indicated for the short-term treatment of insomnia characterized by difficulties with sleep initiation.

Studies of abuse potential in former drug abusers found that the effects of single doses of zolpidem tartrate 40 mg were similar, but not identical, to diazepam 20 mg, while zolpidem tartrate 10 mg was difficult to distinguish from placebo.

Stop taking zolpidem and get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. Zolpidem may cause a severe allergic reaction.

There is evidence from dose comparison trials suggesting a dose relationship for many of the adverse reactions associated with zolpidem use, particularly for certain CNS and gastrointestinal adverse events.

The frequencies presented, therefore, represent the proportions of the 3,660 individuals exposed to zolpidem, at all doses, who experienced an event of the type cited on at least one occasion while receiving zolpidem. All reported treatment-emergent adverse events are included, except those already listed in the table above of adverse events in placebo-controlled studies, those coding terms that are so general as to be uninformative, and those events where a drug cause was remote. It is important to emphasize that, although the events reported did occur during treatment with AMBIEN, they were not necessarily caused by it.
