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 a "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 this drug 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:
Antidepressant medications, including "tricyclic" drugs such as Elavil and such MAO inhibitors as Nardil and Parnate
Antihistamines such as Benadryl and Tavist
Barbiturates such as phenobarbital and Seconal
Cyclosporine (Sandimmune Neoral)
Erythromycin (E.E.S., PCE, E-Mycin, others)

Major tranquilizers such as Mellaril and Thorazine
