zaleplon
Zaleplon, once sold under the brand name Sonata, is a prescription sleep medication for adults. It helps with insomnia (trouble falling asleep). It's a type of sedative-hypnotic called a non-benzodiazepine, or "z-drug." You take it by mouth right before bed or when you're already in bed and can't fall asleep. Zaleplon is a controlled substance because it has a risk of misuse and dependence. Side effects can include headache and dizziness.

- Insomnia (trouble falling asleep)
How Zaleplon works
Zaleplon belongs to the drug class called non-benzodiazepine sedative-hypnotics. People call it a "z-drug" for short.
Zaleplon turns on proteins in the brain called gamma-aminobutyric acid-A (GABA-A) receptors. This helps calm the brain and make it easier to fall asleep.

Risks and warnings for Zaleplon
Zaleplon 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.
Doing things while not fully awake
Zaleplon raises the risk that you might do things while asleep or not fully awake. This can be dangerous and might happen any time you take the medication. These things can include sleepwalking, cooking, eating, talking on the phone, having sex, or even driving. People don't actually remember doing these things after waking up. If a loved one tells you that you did something in your sleep, talk to your prescriber. You might need to stop taking zaleplon.
Sleepiness and trouble focusing the next day
- Risk factors: Not getting at least 7 hours of sleep after taking zaleplon | Taking too much zaleplon | Older age | Drinking alcohol | Taking other medications that make you sleepy or less alert
Zaleplon can make you sleepy. This can raise the risk of falling, especially for older adults. Zaleplon can also make it harder to focus, think, and react. These effects can last until the morning after you take the medication.
These side effects are more likely if you don't get at least 7 hours of sleep after taking zaleplon. The risk is also higher if you drink alcohol or take other medications that make you sleepy, like benzodiazepines or other sleep medications. Tell your care team about all the medications you take so they can help keep you safe.
Only take zaleplon if you can get at least 7 hours of sleep. Take it right before sleeping or when you're already in bed and can't fall asleep. Don't drive or do anything that needs your full attention until you know how this medication affects you (during the night and on the next day). Wait until you feel fully awake and can think clearly.
Dependence and withdrawal
Zaleplon has a risk of physical dependence. This means that your body might get used to the medication and need it to feel normal. If you stop taking the medication or lower your dose too fast, you might have withdrawal symptoms. Symptoms can include trouble sleeping, stomach upset, muscle cramps, sweating, and shakiness.
Take zaleplon exactly as directed. Never change your dose or stop taking zaleplon without talking to your prescriber first. Talk to your prescriber if you want to lower your dose or stop the medication. They'll give you specific instructions on how to do this in a safe way.
Abnormal thoughts and unusual behavior
Some people who take medications like zaleplon can have abnormal thoughts and behavior. This can include acting strangely, being more aggressive, feeling agitated, or having memory problems. Some people also had hallucinations (seeing or hearing things that aren't there). Talk to your prescriber if you have any unusual thoughts or behavior while taking zaleplon.
Severe allergic reaction
- Risk factors: Sensitive to FD&C yellow #5 (tartrazine) food dye
Although it's rare, some people can have a severe allergic reaction to zaleplon. 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 zaleplon.
Caution use in people with breathing problems or depression
If you have breathing problems like chronic obstructive pulmonary disease (COPD) or sleep apnea, talk to your prescriber before starting zaleplon. This medication might affect your breathing. Your prescriber can weigh the risks and benefits for you to take zaleplon.
Also let your prescribe know if you have depression. Medications like zaleplon might make depression worse. Watch for signs of depression and tell your care team if it gets worse. Call 911 right away if you think about hurting yourself.

Pros and cons of Zaleplon
Pros
- Works within 30 minutes or so to help you fall asleep
- Low risk of causing daytime sleepiness since it doesn't stay very long in the body
Cons
- Not shown to help with staying asleep throughout the night
- Not usually recommended to take for more than 30 days because it can be habit-forming
Pharmacist tips for Zaleplon
- Take zaleplon with or without food. If it's hurting your stomach, you can try taking it with a small amount of food or a snack. Keep in mind that taking the medication too close to a heavy, high-fat meal can make it take longer to work.
- Take zaleplon only when you have trouble sleeping. Take it right before bed or when you're already in bed but then can't fall asleep. If you take it while you're still up, you might feel dizzy or lightheaded. You could also have trouble remembering things or moving around safely.
- Take zaleplon only if you can get at least 7 hours of sleep. Otherwise, you might feel extra sleepy or dizzy the next day. You also might have trouble seeing clearly and reacting fast. This can make it hard to focus or do things safely. Don't drive until you're fully awake and alert.
- Some people who take zaleplon might do things while asleep. This can include sleepwalking, driving, cooking, and eating. Sometimes, it can be dangerous. Tell your prescriber if someone's told you that you did something while asleep after taking this medication.
- Avoid drinking alcohol while taking zaleplon. Alcohol can raise your risk of serious side effects, like feeling too sleepy and breathing too slowly.
- Tell your healthcare team about all the medications you take so they can make sure it's safe for you. This is very important if you take opioids or other medications that make you sleepy. Don't take other sleep aids at the same time as zaleplon. These medications can make side effects worse. Taking it with opioids can also make your breathing dangerously slow.
- Don't lower your dose or stop taking zaleplon without talking to your prescriber first. Lowering the dose or stopping too fast can cause withdrawal symptoms. This can include stomach pain, muscle cramps, shaking, and trouble sleeping. Follow your prescriber's instructions to slowly lower the dose to stop the medication safely.
- If your sleep doesn't get any better after 7 to 10 days of taking zaleplon, talk to your prescriber. They can check if something else is making you have trouble sleeping.
- It's a good idea to add in lifestyle changes and strategies to help you sleep better. Talk to your prescriber about how to practice good sleep hygiene.
Common questions about Zaleplon
Yes, zaleplon is a controlled substance because it has a risk of misuse and dependence. To keep people safe, there are federal and state laws that limit how it's prescribed and dispensed. Ask your prescriber to learn more about the medication's risks and regulations.
Some people have reported gaining weight while taking zaleplon, but it's not common. It's also not clear if the medication caused the weight gain. Talk to your prescriber or primary care provider if you notice any unexpected weight changes after starting zaleplon. They can give you tips for weight loss or help you manage you weight.
Zaleplon can help people fall asleep within about 30 minutes after it's taken. Since it works pretty fast, take it right before bed. You can also take it when you're already in bed and can't fall asleep. In both cases, make sure you can get at least 7 hours of sleep after taking zaleplon.
No. Never take zaleplon twice in one night. This can raise your risk of side effects, including headache and feeling very sleepy the next day. It can lead to falls or injuries. Always take zaleplon exactly as prescribed. If it's not helping you fall asleep or if you have trouble staying asleep, talk to your prescriber. You might need a different dose or another medication.
No, zaleplon and zolpidem (Ambien) aren't the same. They're both non-benzodiazepines that calm the brain and help you sleep. But they're two different medications. Their role in helping with the sleep process is different. Zaleplon only helps people fall asleep. It isn't a good choice for people who need help staying asleep because it doesn't last for a long time. But some forms of zolpidem (Ambien) can help with both falling asleep and staying asleep. Talk to your prescriber to learn more about both medications.
No, zaleplon isn't a benzodiazepine. It's actually a non-benzodiazepine sedative-hypnotic, or also called a "z-drug." But it works in a similar way to benzodiazepines to help with sleep. They both make it easier to sleep by calming the brain.
Talk to your prescriber if you're pregnant, planning to become pregnant, or breastfeeding. In general, zaleplon isn't recommended during pregnancy or while nursing. We don't fully know how safe it is during pregnancy. Zaleplon can also pass into breast milk. If you breastfeed while taking this medication, it could make your baby sleepy or have trouble feeding. Discuss the risks and benefits of taking zaleplon with your prescriber. They can help find the safest option for you.
