Halcion


Halcion

Generic name: TriazolamBrand names: Halcion

Why is Halcion prescribed?

Halcion is used for short-term treatment of insomnia. It is a member of the benzodiazepine class of drugs, many of which are used as tranquilizers.

Most important fact about Halcion

Sleep problems are usually temporary, requiring treatment for only a short time, usually 1 or 2 days and no more than 1 to 2 weeks. Insomnia that lasts longer than this may be a sign of another medical problem. If you find you need this medicine for more than 7 to 10 days, be sure to check with your doctor.

How should you take Halcion?

Take Halcion exactly as directed; never take more than your doctor has prescribed.

  • If you miss a dose...Take Halcion only as needed.
  • Storage instructions...Keep Halcion in the container it came in, tightly closed, and out of reach of children. Store it at room temperature.

What side effects may occur?

Side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue taking Halcion.

  • Side effects may include:Coordination problems, dizziness, drowsiness, headache, light-headedness, nausea/vomiting, nervousness

Why should Halcion not be prescribed?

You should not take Halcion if you are pregnant or if you have had an allergic reaction to it or to other benzodiazepine drugs such as Valium.

Also avoid Halcion if you are taking the antifungal medications itraconazole, or ketoconazole, or the antidepressant nefazodone.

Special warnings about Halcion

When Halcion is used every night for more than a few weeks, it loses its effectiveness to help you sleep. This is known as tolerance. Also, it can cause dependence, especially when it is used regularly for longer than a few weeks or at high doses.

Abrupt discontinuation of Halcion should be avoided, since it has been associated with withdrawal symptoms (convulsions, cramps, tremor, vomiting, sweating, feeling ill, perceptual problems, and insomnia). A gradual dosage tapering schedule is usually recommended for patients taking more than the lowest dose of Halcion for longer than a few weeks. The usual treatment period is 7 to 10 days.

If you develop unusual and disturbing thoughts or behavior—including increased anxiety or depression—during treatment with Halcion, you should discuss them with your doctor immediately.

"Traveler's amnesia" has been reported by patients who took Halcion to induce sleep while traveling. To avoid this condition, do not take Halcion on an overnight airplane flight of less than 7 to 8 hours.

You may suffer increased anxiety during the daytime while taking Halcion.

When you first start taking Halcion, until you know whether the medication will have any carry over effect the next day, use extreme care while doing anything that requires complete alertness such as driving a car or operating machinery.

After discontinuing the drug, you may experience rebound insomnia for the first 2 nights—that is, insomnia may be worse than before you took the sleeping pill.

You should be aware that anterograde amnesia (forgetting events after an injury) has been associated with benzodiazepine drugs such as Halcion.

You should be cautious about using Halcion if you have liver or kidney problems, lung problems, or a tendency to temporarily stop breathing while you are asleep.

Possible food and drug interactions when taking Halcion

Avoid alcoholic beverages and grapefruit juice.

If Halcion is taken with certain other drugs, the effects of either could be increased, decreased, or altered. It is especially important to check with your doctor before combining Halcion with the following:
