Zolpidem is used to treat sleep problems (insomnia) in adults. It helps you fall asleep faster and stay asleep longer, so you can get a better night's sleep. It may also reduce the number of times you wake up during the night. Zolpidem belongs to a class of drugs called sedative-hypnotics. It acts on your brain to produce a calming effect.
Take this medication by mouth on an empty stomach as directed by your doctor, usually once a night. Since zolpidem works quickly, take it right before you get into bed. Do not take it with or after a meal because it will not work as quickly.
Do not crush or chew extended-release tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.
Do not take a dose of this drug unless you have time for a full night's sleep of at least 7 to 8 hours. If you have to wake up before that, you may have some memory loss and may have trouble safely doing any activity that requires alertness, such as driving or operating machinery. (See also Precautions section.)
Dosage is based on your gender, age, medical condition, other medications you may be taking, and response to treatment. Do not increase your dose, take it more often, or use it for longer than prescribed. Do not take more than 12.5 milligrams a day. Women are usually prescribed a lower dose because the drug is removed from the body more slowly than in men. Older adults are usually prescribed a lower dose to decrease the risk of side effects.
This medication may cause withdrawal reactions, especially if it has been used regularly for a long time or in high doses. In such cases, withdrawal symptoms (such as nausea, vomiting, flushing, stomach cramps, nervousness, shakiness) 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 right away.
Along with its benefits, this medication may rarely cause abnormal drug-seeking behavior (addiction). This risk may be increased if you have abused alcohol or drugs in the past. Take this medication exactly as prescribed to lessen the risk of addiction.
When this medication is used for a long time, it may not work as well. Talk with your doctor if this medication stops working well.
Tell your doctor if your condition persists after 7 to 10 days, or if it worsens.
You may have trouble sleeping the first few nights after you stop taking this medication. This is called rebound insomnia and is normal. It will usually go away after 1-2 nights. If this effect continues, contact your doctor.
This medication may make you sleepy during the day. Tell your doctor if you have daytime drowsiness. Your dose may need to be adjusted.
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 right away if any of these unlikely but serious side effects occur: memory loss, mental/mood/behavior changes (such as new/worsening depression, abnormal thoughts, thoughts of suicide, hallucinations, confusion, agitation, aggressive behavior, anxiety).
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 right away. Your risk is increased if you use alcohol or other medications that can make you drowsy while taking zolpidem.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
