Dose reference #

Adult educational reference · Oral tablet · United States. The clinician selects treatment after assessment; this page does not calculate or change a prescription.

Selected initial anxiety dose: 2–3 mg/day in two or three doses; usual range 2–6 mg/day. Individualize to response and sedation.

Contraindications & important cautions #

Avoid acute narrow-angle glaucoma and hypersensitivity. Opioids/alcohol increase respiratory depression; assess dependence risk.

Selected important cautions; consult the full product information for all contraindications and warnings.

Adverse effects #

Sedation, amnesia, motor impairment, dependence and withdrawal; respiratory risk rises with other depressants.

Interactions #

Assess opioids, alcohol and other sedatives. Different routes have different administration/monitoring requirements.

Monitoring #

Review indication, duration, response, sedation and respiratory context. Abrupt withdrawal after dependence can be dangerous.

Special populations #

Older/debilitated patients: initial 1–2 mg/day divided. Review respiratory disease, hepatic illness and pregnancy/neonatal effects.

Adult scope. Pregnancy, breastfeeding and pediatric use require the exact product’s population-specific guidance and individual assessment.

Discontinuation, restarting & counseling #

Use a gradual individualized taper; abrupt cessation may cause seizures or delirium.

Condition-specific prescribing #

Additional indication-specific records retain their own formulation and source context.
