Sonata Side Effects Center

Medical Editor: John P. Cunha, DO, FACOEP

Sonata (zaleplon) is used to treat insomnia. Sonata is in the non-benzodiazepine sedative hypnotic drug class. This medication is available in generic form. Common side effects include dizziness, drowsiness, short-term memory loss, or lack of coordination, especially during the first 2 hours after you take the medication. Taking the medication properly just before falling asleep will reduce your risk of these effects. Some people using Sonata have engaged in activity such as driving, eating, or making phone calls and later having no memory of the activity. If this happens to you, stop taking this medication and talk with your doctor about another treatment for your sleep disorder.

The dose of Sonata should be individualized. The recommended dose for most adults is 10 mg. For some patients, 5 mg may be a sufficient dose. Sonata may interact with cimetidine, thioridazine, promethazine, cyclosporine, rifampin, antibiotics, antidepressants, narcotic pain medications, muscle relaxers, seizure medications, or anti-anxiety medications. Tell your doctor all medications you are taking. Sonata should be used only when prescribed during pregnancy. Discuss the risks and benefits with your doctor. This medication passes into breast milk and may have undesirable effects on a nursing infant. Consult your doctor before breast-feeding. Sonata may be habit-forming and should be used only by the person it was prescribed for. You may have withdrawal symptoms if you stop taking Sonata. Do not stop taking Sonata suddenly without first talking to your doctor.

Sonata Overview - Patient Information: Side Effects

SIDE EFFECTS: Dizziness, drowsiness, short-term memory loss, or lack of coordination may occur, especially during the first 2 hours after you take the medication. Taking the medication properly just before falling asleep will reduce your risk of these effects. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.

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.

Tell your doctor immediately if any of these unlikely but serious side effects occur: mental/mood changes (e.g., agitation, confusion, seeing/hearing things that are not there, rare thoughts of suicide), unusual behavior.

Rarely, after taking this drug, people have gotten out of bed and driven vehicles while not fully awake ("sleep-driving"). People have also sleepwalked, prepared/eaten food, made phone calls, or had sex while not fully awake. Often, these people do not remember these events. This problem can be dangerous to you or to others. If you find out that you have done any of these activities after taking this medication, tell your doctor immediately. Your risk is increased if you use alcohol or other medications that can make you drowsy while taking zaleplon.

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.

Sonata FDA Prescribing Information: Side Effects
(Adverse Reactions)

SIDE EFFECTS

The premarketing development program for Sonata (zaleplon) included zaleplon exposures in patients and/or normal subjects from 2 different groups of studies: approximately 900 normal subjects in clinical pharmacology/pharmacokinetic studies; and approximately 2,900 exposures from patients in placebo-controlled clinical effectiveness studies, corresponding to approximately 450 patient exposure years. The conditions and duration of treatment with Sonata (zaleplon) varied greatly and included (in overlapping categories) open-label and double- blind phases of studies, inpatients and outpatients, and short-term or longer-term exposure. Adverse reactions were assessed by collecting adverse events, results of physical examinations, vital signs, weights, laboratory analyses, and ECGs.

Adverse events during exposure were obtained primarily by general inquiry and recorded by clinical investigators using terminology of their own choosing. Consequently, it is not possible to provide a meaningful estimate of the proportion of individuals experiencing adverse events without first grouping similar types of events into a smaller number of standardized event categories. In the tables and tabulations that follow, COSTART terminology has been used to classify reported adverse events.

The stated frequencies of adverse events represent the proportion of individuals who experienced, at least once, a treatment-emergent adverse event of the type listed. An event was considered treatment-emergent if it occurred for the first time or worsened while receiving therapy following baseline evaluation.

Adverse Findings Observed in Short-Term, Placebo-Controlled Trials

Adverse Events Associated With Discontinuation of Treatment

In premarketing placebo-controlled, parallel-group phase 2 and phase 3 clinical trials, 3.1% of 744 patients who received placebo and 3.7% of 2,149 patients who received Sonata (zaleplon) discontinued treatment because of an adverse clinical event. This difference was not statistically significant. No event that resulted in discontinuation occurred at a rate of ≥ 1%.

Adverse Events Occurring at an Incidence of 1% or More Among Sonata (zaleplon) 20 mg-Treated Patients

Table 1 enumerates the incidence of treatment-emergent adverse events for a pool of three 28-night and one 35- night placebo-controlled studies of Sonata (zaleplon) at doses of 5 mg or 10 mg and 20 mg. The table includes only those events that occurred in 1% or more of patients treated with Sonata (zaleplon) 20 mg and that had a higher incidence in patients treated with Sonata (zaleplon) 20 mg than in placebo-treated patients.

The prescriber should be aware that these figures cannot be used to predict the incidence of adverse events in the course of usual medical practice where patient characteristics and other factors differ from those which 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 non-drug factors to the adverse event incidence rate in the population studied.

Other Adverse Events Observed During the Premarketing Evaluation of Sonata (zaleplon)

Listed below are COSTART terms that reflect treatment-emergent adverse events as defined in the introduction to the ADVERSE REACTIONS section. These events were reported by patients treated with Sonata (zaleplon) at doses in a range of 5 mg/day to 20 mg/day during premarketing phase 2 and phase 3 clinical trials throughout the United States, Canada, and Europe, including approximately 2,900 patients. All reported events are included except those already listed in Table 1 or elsewhere in labeling, those events for which a drug cause was remote, and those event terms that were so general as to be uninformative.

Drug Abuse And Dependence

Controlled Substance Class

Sonata (zaleplon) is classified as a Schedule IV controlled substance by federal regulation.

Abuse, Dependence, and Tolerance

Abuse and addiction are separate and distinct from physical dependence and tolerance. Abuse is characterized by misuse of the drug for non-medical purposes, often in combination with other psychoactive substances. Physical dependence is a state of adaption that is manifested by a specific withdrawal syndrome that can be produced by abrupt cessation, rapid dose reduction, decreasing blood level of the drug and/or administration of an antagonist. 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's effects over time. Tolerance may occur to both the desired and undesired effects of drugs and may develop at different rates for different effects.

Addiction is a primary, chronic, neurobiological disease with genetic, psychosocial, and environmental factors influencing its development and manifestations. 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, utilizing a multidisciplinary approach, but relapse is common.

Abuse

Two studies assessed the abuse liability of Sonata (zaleplon) at doses of 25 mg, 50 mg, and 75 mg in subjects with known histories of sedative drug abuse. The results of these studies indicate that Sonata (zaleplon) has an abuse potential similar to benzodiazepine and benzodiazepine-like hypnotics.

Dependence

The potential for developing physical dependence on Sonata (zaleplon) and a subsequent withdrawal syndrome was assessed in controlled studies of 14-, 28-, and 35-night durations and in open-label studies of 6- and 12-month durations by examining for the emergence of rebound insomnia following drug discontinuation. Some patients (mostly those treated with 20 mg) experienced a mild rebound insomnia on the first night following withdrawal that appeared to be resolved by the second night. The use of the Benzodiazepine Withdrawal Symptom Questionnaire and examination of any other withdrawal-emergent events did not detect any other evidence for a withdrawal syndrome following abrupt discontinuation of Sonata (zaleplon) therapy in pre-marketing studies.

However, available data cannot provide a reliable estimate of the incidence of dependence during treatment at recommended doses of Sonata (zaleplon) . Other sedative/hypnotics have been associated with various signs and symptoms following abrupt discontinuation, ranging from mild dysphoria and insomnia to a withdrawal syndrome that may include abdominal and muscle cramps, vomiting, sweating, tremors, and convulsions. Seizures have been observed in two patients, one of which had a prior seizure, in clinical trials with Sonata (zaleplon) . Seizures and death have been seen following the withdrawal of zaleplon from animals at doses many times higher than those proposed for human use. Because individuals with a history of addiction to, or abuse of, drugs or alcohol are at risk of habituation and dependence, they should be under careful surveillance when receiving Sonata (zaleplon) or any other hypnotic.

Tolerance

Possible tolerance to the hypnotic effects of Sonata (zaleplon) 10 mg and 20 mg was assessed by evaluating time to sleep onset for Sonata (zaleplon) compared with placebo in two 28-night placebo-controlled studies and latency to persistent sleep in one 35-night placebo-controlled study where tolerance was evaluated on nights 29 and 30. No development of tolerance to Sonata (zaleplon) was observed for time to sleep onset over 4 weeks.
