Flurazepam is used to treat sleeping problems (insomnia). It's a controlled substance because it has a risk for becoming habit-forming. The brand name Dalmane has been discontinued, but it's still available as generic versions. Side effects of the medication include headache and upset stomach.
Insomnia (trouble sleeping)
Flurazepam is a benzodiazepine. It affects chemicals in the brain to calm down your nervous system, helping you fall asleep and stay asleep.
Flurazepam can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Taking flurazepam with opioids
Combining flurazepam with pain medications called opioids can cause a life-threatening interaction that might cause you to be extremely sleepy or stop breathing. This can lead to coma or death. It's very important not to combine flurazepam with opioids unless you're under close supervision of a healthcare provider. Get emergency help if you feel like you are having trouble breathing or can't wake up very easily after taking flurazepam. Educate those around to keep an eye out for these side effects as well.
Risk factors: History of substance misuse | Taking with alcohol or illicit drugs | Taking flurazepam for a long time | Stopping flurazepam suddenly
Flurazepam is a controlled medication because it has a high risk of addiction and misuse. Your body can also become dependent on the medication even if you're taking it as exactly as directed. Taking flurazepam for the shortest amount of time needed can lower these risks.
If you've been taking flurazepam for a long time, talk to your provider before stopping. Stopping flurazepam suddenly can lead to withdrawals, which can cause serious symptoms, including seizures. In some causes, withdrawal symptoms can last weeks to more than a year at a time. If you need to stop this medication, your provider can help you do so safely by lowering your dose slowly over time.
Risk factors: Alcohol use | Taking other medications that make you less alert | High doses
Flurazepam can weaken your ability to focus, think, and react. These effects can last until the morning after taking flurazepam. Be careful and avoid activities that require you to be alert, such as driving a car or operating machinery, until you know how this medication affects you.
In some rare cases, flurazepam can cause an allergic reaction. Some reactions can be life-threatening and require emergency medical treatment. If you experience trouble breathing, hives, or swelling in your face, lips, tongue, or throat, get medical attention right away.
Risk factors: Taking higher doses of flurazepam | Drinking alcohol | Taking other medications that cause sleepiness
Flurazepam can cause behavioral and personality changes. Some people have reported lower inhibitions (meaning you may do things you wouldn't normally do), aggressiveness, agitation, and hallucinations (seeing or hearing things that aren't there). There are also reports of people sleep-driving or doing other activities while asleep and having no memory of it the next morning. Talk to your provider if you're doing potentially dangerous activities while you're sleeping. There might be other sleep medications that are safer for you.
