Concomitant use of benzodiazepines and opioids may result in profound respiratory depression, coma, and death; administer concomitantly when there are no alternative options; limit dosages and durations to minimum required; monitor for signs and symptoms of respiratory depression and sedation
Contraindications
Documented hypersensitivity
Acute alcohol intoxication
Narrow-angle glaucoma (questionable)
Caution
Use caution in COPD, sleep apnea, renal/hepatic disease, impaired gag reflex, open-angle glaucoma (questionable), alcoholism, respiratory disease, depression, suicidal ideation
May impair ability to perform hazardous tasks
Caution with IV use in shock, coma, and depressed respiration and in patients who recently received other respiratory depressants
Anterograde amnesia may occur
Use caution in patients with history of drug abuse or acute alcoholism; tolerance, psychological and physical dependence may occur with prolonged use
Use in myasthenia gravis is allowed in limited circumstances
Use caution in severe respiratory depression and depressed neuroses, psychotic reactions

Pregnancy & Lactation
Pregnancy Category: X
Lactation: Avoid if breastfeeding
Minor tranquilizers should be avoided in 1st trimester of pregnancy due to increased risk of congenital malformations
Maternal use shortly before delivery is associated with floppy infant syndrome (good and consistent evidence)
Prenatal benzodiazepine exposure slightly increased oral cleft risk (limited or inconsistent evidence)
Pregnancy Categories
A:Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B:May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.
C:Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.
D:Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.
X:Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.
NA:Information not available.
Pharmacology
Mechanism of Action
Depresses all levels of CNS (eg, limbic and reticular formation), possibly by increasing membrane permeability to chloride ions, which in turn increases the inhibitory activity of GABA on neuronal excitability.

Distribution

Vd: 1.4 L/kg
Metabolism
Metabolized by CYP3A4 (minor), glucuronic acid conjugation
Metabolites: Inactive
Elimination
Half-life elimination: 9.5-12.4 hr
