HALCION®, CIV (triazolam) Medication Guide

HALCION (HAL-cee-on)
(triazolam) Tablets, C-IV
What is the most important information I should know about HALCION?
  • HALCION is a benzodiazepine medicine. Taking benzodiazepines with opioid medicines, alcohol, or other central nervous system depressants (including street drugs) can cause severe drowsiness, breathing problems (respiratory depression), coma and death.
  • After taking HALCION, you may get up out of bed while not being fully awake and do an activity that you do not know you are doing. The next morning, you may not remember that you did anything during the night. You have a higher chance for doing these activities if you drink alcohol or take other medicines that make you sleepy with HALCION. Reported activities include:
    • driving a car ("sleep-driving")
    • making and eating food
    • talking on the phone
    • having sex
    • sleep-walking
    Call your healthcare provider right away if you find out that you have done any of the above activities after taking HALCION.
  • Do not take HALCION unless you are able to stay in bed a full night (7 to 8 hours) before you must be active again.
  • Do not take more HALCION than prescribed.
What is HALCION?
  • HALCION is a prescription medicine used to treat certain types of insomnia including difficulty falling asleep, waking up often during the night, or waking up early in the morning.
  • HALCION is a federal controlled substance (C-IV) because it can be abused or lead to dependence. Keep HALCION in a safe place to prevent misuse and abuse. Selling or giving away HALCION may harm others, and is against the law. Tell your healthcare provider if you have ever abused or been dependent on alcohol, prescription medicines or street drugs.
  • It is not known if HALCION is safe and effective in children.
  • Elderly patients are especially susceptible to dose related adverse effects when taking HALCION.
  • It is not known if HALCION is safe and effective for use longer than 2 to 3 weeks.
Do not take HALCION if you:
  • are allergic to triazolam, other benzodiazepines, or any of the ingredients in HALCION. See the end of this Medication Guide for a complete list of ingredients in HALCION.
  • take antifungal medicines including ketoconazole and itraconazole
  • take a medicine to treat depression called nefazodone
  • take medicines to treat HIV infection called protease inhibitors, including ritonavir, indinavir, nelfinavir, saquinavir or lopinavir

Tell your healthcare provider about all of the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Do not take HALCION with other medicines that can make you sleepy. Taking HALCION with certain other medicines can cause side effects or affect how well HALCION or the other medicines work. Do not start or stop other medicines without talking to your healthcare provider.
