ZALEPLON - ORAL
COMMON BRAND NAME(S): Sonata
USES: This medication is used for a short time to treat people who have trouble falling asleep. If you have other sleep problems such as not being able to sleep through the night, this medication may not be right for you. Zaleplon is known as a hypnotic. It works on certain centers in the brain to relax you and help you fall asleep faster.
HOW TO USE: Read the Medication Guide provided by your pharmacist before you start taking zaleplon and each time you get a refill. If you have any questions, consult your doctor or pharmacist. Take this medication by mouth as directed by your doctor. Zaleplon works very quickly, so it is important to take it just before or when you get into bed. Zaleplon should not be used for naps or short sleep periods of less than 4 hours because this may increase your risk of side effects such as memory loss or drowsiness. Your doctor will work with you to find the smallest dose that works for you. You should not eat a very heavy/high-fat meal within 2 hours before taking this medication since doing so may prevent the drug from working properly. Dosage is based on your medical condition and response to therapy. Since this medication is usually prescribed for a short time, your doctor will tell you when to stop taking it or when to cut back. You may feel anxious or have trouble falling asleep in the first day or two after stopping this medication (rebound insomnia). Contact your doctor if you continue to have trouble falling asleep several days after stopping zaleplon. This medication may cause withdrawal reactions, especially if it has been used regularly for a long time (more than a few weeks) or in high doses. In such cases, withdrawal symptoms (such as unusual depressed/anxious mood, stomach/muscle cramps, vomiting, sweating, shakiness, or seizures) may occur if you suddenly stop using this medication. To prevent withdrawal reactions, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details, and report any withdrawal reactions immediately. Though it is very unlikely to occur, this medication can also result in abnormal drug-seeking behavior (addiction/habit forming). Do not increase your dose, take it more frequently, or use it for a longer time than prescribed. Properly stop the medication when so directed. This will lessen the chances of becoming addicted. Inform your doctor if your condition persists or worsens.
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, 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.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: liver problems, very high/low blood pressure, breathing problems (e.g., asthma), depression, history of drug/alcohol abuse.

Do not start, stop or change the dosage of any medicine before checking with them first. This drug should not be used with the following medication because very serious interactions may occur: sodium oxybate. If you are currently using the medication listed above, tell your doctor or pharmacist before starting zaleplon.

Tell your doctor or pharmacist if you also take drugs that cause drowsiness such as: certain antihistamines (e.g., diphenhydramine, promethazine), anti-seizure drugs (e.g., levetiracetam), other drugs for sleep or anxiety (e.g., alprazolam, diazepam, zolpidem), muscle relaxants (e.g., cyclobenzaprine, carisoprodol), narcotic pain relievers (e.g., codeine), psychiatric medicines (e.g., thioridazine, risperidone, amitriptyline, trazodone).
