This medication is used to treat sleep problems (insomnia). It may help you fall asleep faster, stay asleep longer, and lessen how often you wake up during the night, so you can get a better night's rest. Flurazepam belongs to a class of drugs called sedative-hypnotics. It acts on your brain to produce a calming effect.
Use of this medication is usually limited to treatment periods of 1 to 2 weeks or less. If your insomnia continues for a longer time, talk to your doctor to see if you need other treatment.
Read the Medication Guide provided by your pharmacist before you start taking flurazepam and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth with or without food as directed by your doctor, usually just before you get into bed. The dosage is based on your medical condition, age, and response to treatment.
Although unlikely, this drug can infrequently cause temporary short-term memory loss. To lessen the chance of this, 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.
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 immediately.
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.
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.
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 or 2 nights. If this effect continues, contact your doctor.
Dizziness or difficulty with coordination may occur. If either of these effects persists or worsens, tell your doctor or pharmacist promptly. To reduce the risk of dizziness or falling, get up slowly when rising from a sitting or lying position.
This medication may make you sleepy during the day. Tell your doctor if you have daytime drowsiness. Your dose may need to be adjusted.
Tell your doctor right away if you have any serious side effects, including: 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 flurazepam.
