Halcion (Triazolam)

Halcion (triazolam) is indicated for short‑term treatment of insomnia when rapid onset of sleep is required.

• Short‑term relief of difficulty falling asleep, typically within 30 minutes.
• Management of transient insomnia episodes that disrupt daily functioning.
• Use in adults who require rapid sleep induction for shift‑work or jet‑lag.
• Adjunct therapy when non‑pharmacologic measures, such as sleep hygiene, are insufficient.
• Prescribed for a limited duration, usually not exceeding two weeks, to reduce tolerance.

Side effects of Halcion vary in frequency and severity; they are categorized as common or serious.

Common

• Drowsiness or fatigue, especially after the first dose.
• Light‑headedness or dizziness that may affect coordination.
• Impaired balance or motor skills, increasing fall risk.
• Memory disturbances, such as anterograde amnesia for events after dosing.
• Mood changes, including irritability or mild depression.

Serious

• Respiratory depression, particularly when combined with other depressants.
• Severe allergic reactions, such as rash, itching, swelling, or anaphylaxis.
• Paradoxical reactions, including agitation, aggression, or hallucinations.

When prescribing Halcion, clinicians consider several precautions to minimize risks and ensure safe use.

• Limit use to the shortest effective period to avoid dependence.
• Assess for a history of substance abuse or addiction.
• Avoid use in patients with severe respiratory disorders.
• Use with caution in the elderly due to increased fall risk.
• Contraindicated during pregnancy because of fetal risk (Category D).
• Monitor for signs of withdrawal upon discontinuation.

Halcion may interact with other medications, affecting its sedative properties or metabolism.

Avoid

• Other central nervous system depressants (e.g., opioids, barbiturates, alcohol).
• Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin).
• Drugs that prolong the QT interval.

Use with caution

• Antidepressants that lower seizure threshold.
• Other benzodiazepines or sedative‑hypnotics.
