Quazepam, also known by its brand name Doral, is a benzodiazepine that's used to treat insomnia. It helps adults fall asleep, stay asleep, or avoid waking up too early. You take a dose right before you go to bed as needed for sleep and plan to sleep for at least 8 hours. Otherwise, you might feel very groggy the next day, which is a common side effect of the medication. Quazepam (Doral) is only for short-term use because it can be habit-forming.
Insomnia (trouble falling asleep or staying asleep)
Quazepam (Doral) is a benzodiazepine, or "benzo" for short. It's thought to attach to proteins in the brain called gamma-aminobutyric acid (GABA) receptors. This helps calm the brain, which makes it easier to fall asleep and stay asleep.
Quazepam (Doral) 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.
Taking quazepam (Doral) with opioid medications is dangerous. It can make you very sleepy and slow down your breathing, which can be life-threatening.
Because of these risks, it's important to talk to your prescriber or pharmacist if you need to take both a benzodiazepine and an opioid. They can help you find the safest option. Don't drive or use heavy machines until you're fully alert.
Risk factors: Taking higher-than-recommended doses of quazepam (Doral) | Taking with illicit substances or other dangerous medications | Drinking alcohol
To lower your risk, take quazepam (Doral) only as prescribed. Take the lowest dose for the shortest amount of time to help you sleep. Talk to your prescriber if you're worried about these risks.
Risk factors: Taking quazepam (Doral) for a long time | Taking quazepam (Doral) at a higher dose or more often | Stopping the medication suddenly
Taking quazepam (Doral) for a long time or at high doses can lead to physical dependence. This is when your body gets used to the medication and needs it to feel normal.
If you suddenly lower your dose or stop taking quazepam (Doral), you might have withdrawal symptoms. These can include an upset stomach, muscle aches, shaking, headache, anxiety, trouble sleeping, and in rare cases, seizures. These symptoms can be uncomfortable and sometimes dangerous.
Always take quazepam (Doral) as instructed by your prescriber. Don't stop or change your dose without talking to your prescriber first. They can help you slowly lower the dose to stop the medication safely.
Risk factors: Sleeping fewer than 7 to 8 hours after taking quazepam (Doral) | Drinking alcohol | Taking a higher dose of quazepam (Doral) | Taking other medications that can make you sleepy
People who take quazepam (Doral) can feel sleepy and have trouble focusing the next day. This can be dangerous, especially for older adults, because it raises the risk of falling.
These side effects are more likely to happen if you don't get at least 7 to 8 hours of sleep after taking quazepam (Doral). The risk is also higher if you drink alcohol or take other medications that make you sleepy, like other benzodiazepines or opioids.
Don't drive or do anything that needs your full attention if you still feel sleepy. Wait until you feel fully awake and can think clearly to stay safe.
In some rare cases, quazepam (Doral) can cause serious allergic reactions. This can happen any time you take the medication. Allergic reactions can include swelling of the face, tongue, neck, or throat. Other symptoms are trouble breathing, closing of the throat, nausea, or vomiting. Call 911 right away if you have signs of an allergic reaction after taking quazepam (Doral).
Some people taking quazepam (Doral) have had changes in thinking and behavior. This can include acting strangely or being more aggressive. Some also had hallucinations (seeing or hearing things that aren't real). And others had memory problems or sleep issues. Talk to your prescriber if any unusual thoughts or behavior happen while you're taking this medication.
Risk factors: Higher dose of quazepam (Doral) | Drinking alcohol | Also taking other medications that slow the body down
Sometimes after taking quazepam (Doral), people can do things in their sleep or when they're not fully awake. They include sleepwalking, cooking, eating, making phone calls, and having sex. Some people might even drive while asleep, which is very dangerous. Most people don't remember doing these things. So if you've been told that you've done something like this in your sleep, talk to your prescriber. You'll need to stop taking quazepam (Doral).
Benzodiazepines like quazepam (Doral) can make depression worse. Tell your prescriber if you have depression before starting this medication. They can keep an eye on your mental health. Let your care team know if your depression gets worse. And call 911 right away if you think about hurting yourself.
Tell your prescriber right away if you become pregnant while taking quazepam (Doral). They can help you find a safer option.
Quazepam (Doral) can harm your baby, especially if it's taken late in pregnancy. It can make your newborn very tired, have slow breathing, or have withdrawal. Signs of withdrawal include shaking, crying a lot, trouble feeding, or twitching. Sometimes, these effects can be dangerous. Healthcare specialists trained in newborn care can help if this happens.
