Triazolam (Halcion) 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.
Serious risks when taking triazolam (Halcion) and opioids together
Mixing triazolam (Halcion) with certain pain medications called opioids can be life-threatening. Taking these two types of medications together can make you extremely sleepy and can possibly stop your breathing.
It's very important not to combine triazolam (Halcion) with opioids unless it's absolutely necessary and unless you're closely supervised by a healthcare professional (HCP). Get emergency help if you feel like you're having trouble breathing or you can't wake up easily after you take triazolam (Halcion).
Potential for misuse and addiction
Risk factors: Personal or family history of alcohol or substance use disorder | Personal or family history of mental health problems
Triazolam (Halcion) is a controlled substance because it has a risk for misuse and addiction. Misusing this medication can raise the risk for serious and possibly life-threatening side effects, such as dangerously slow breathing, not being able to stay awake, and death.
To lower your risk for misuse and addiction, take triazolam (Halcion) exactly as prescribed. Don't change the dose or how often you take it without talking to your prescriber first. They'll prescribe the lowest amount of medication that's necessary to help you sleep for the shortest period of time possible.
Physical dependence and withdrawal
Risk factors: Taking triazolam (Halcion) for a long time | Stopping triazolam (Halcion) suddenly
Taking triazolam (Halcion) for a long period of time can lead to physical dependence. This happens when your body starts relying on the medication to function normally . And you could have withdrawal symptoms if you suddenly stop taking triazolam (Halcion). These withdrawal symptoms can include difficulty sleeping, nausea, muscle pain, and more nervousness. To lower your risk for dependence and withdrawal, your healthcare team will only prescribe the lowest possible dose to treat your insomnia for the shortest amount of time.
Unusual behavior while sleeping
Risk factors: Drinking alcohol | Taking other medications for sleep or anxiety
Medications like triazolam (Halcion) have caused people to have unusual sleep behavior. This includes "sleep driving," cooking and eat food, making phone calls, and other behaviors that happen while you're asleep. In most cases, you don't remember that these behaviors happened. Let your prescriber know if your loved ones notice these behaviors while you're sleeping.
Changes in thoughts or behavior
Some people who take triazolam (Halcion) might feel more anxious during the day, confused, outgoing, irritable, or aggressive. It's also possible to have amnesia (memory loss) for a few hours after you take the medication. And people with depression might experience worsened symptoms, including thoughts of self-harm, while they're taking triazolam (Halcion). Let your prescriber know if you notice unusual changes in your mood or personality. Get medical attention right away if you have any thoughts of harming yourself.
Effects on driving and concentration
Risk factors: Drinking alcohol | Taking other medications that make you less alert | High doses
Triazolam (Halcion) can lower your ability to focus, think, and react. 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.
Difficulty breathing
In people with breathing problems, triazolam (Halcion) can slow down breathing or stop breathing for a brief period of time. Let your prescriber know right away if you or your partner notices a change in how well you're able to breathe while you're taking this medication. Triazolam (Halcion) might not be safe for you.
Harm to unborn baby
Triazolam (Halcion) can cause harm to your baby if you're pregnant. Taking this medication during late pregnancy can raise the risk that your baby has serious side effects after they're born. These side effects can include dangerously slowed breathing, limpness, and withdrawal symptoms like irritability, restlessness, and poor feeding. Speak with your healthcare team about other options to help you get good sleep if you're pregnant or planning to become pregnant.
Interactions with other medications
Triazolam (Halcion) can interact with some other medications. For example, certain medications can cause the levels of triazolam (Halcion) in the body to get dangerously high. This can raise the risk for serious side effects. Some medications that can interact with triazolam (Halcion) in this way include antibiotics like clarithromycin, antifungals like ketoconazole, and certain HIV medications called protease inhibitors.
Speak with your prescriber and pharmacist about all the medications, including over-the-counter medications and supplements, you're taking or plan to take. They might need to make dose adjustments to some of your medications or they might recommend other safer options.

Triazolam (Halcion) is only meant for short-term use (7 to 10 days at a time).

Your prescriber can also suggest other ways to get better sleep.
Only take triazolam (Halcion) if you know you're going to bed right away. Taking this medication during the day can lead to daytime sleepiness.
Triazolam (Halcion) can make you sleepy, less alert, and have trouble thinking clearly and reacting quickly. Don't drive or do anything that requires concentration the next day after you take triazolam (Halcion) until you know how the medication affects you.
Don't drink alcohol while you're taking triazolam (Halcion). Mixing this medication with alcohol can make you extremely sleepy and can slow down your breathing.
